How the Eye Lens Stays Clear 08/28/2003
To act as a true lens that can focus light, the lens of the eye
must remain transparent for a lifetime. Yet the eye lens is
not a piece of glass, but a growing, living tissue made up of cells.
How can such a tissue stay clear, when the cells must be nourished,
and when they contain organelles and chromosomes that would tend to
obscure light?
Actually, that is exactly the problem with cataracts,
one of the leading causes of blindness, in which the lens becomes
clouded. Scientists at
Bassnet
Labs at Washington University (St. Louis, Missouri) have been
studying how the eye maintains transparency, and found an enzyme that,
when it fails, leads to cataracts in mice. The job of this
enzyme is to chop up and dispose of DNA in lens cells.
In a normal eye, Light can pass through the lens
because the cells break down their internal structures during
development, reports
Science
Now. Nagata et al. at the lab found large amounts of
an enzyme named DLAD in mouse lens cells that chops up DNA for disposal.
Mice lacking this enzyme developed cataracts. Failures in this
enzyme, or the gene that codes for it, are also probably implicated in
cataract development in humans.
Their work, published in
Nature
Aug. 28, explains how lens cells develop:
The eye lens is composed of fibre cells, which develop from
the epithelial cells on the anterior surface of the lens.
Differentiation into a lens fibre cell is accompanied by changes
in cell shape, the expression of crystallins and the degradation
of cellular organelles. Until now it was not known how
the cell dismantled its organelles and DNA. The fibre cells
have their nuclei removed during maturation, but the DNA remains.
It is the job of DLAD to act like a chipper and degrade the long
DNA molecules into fragments that can be expelled. Even if
the other aspects of fibre-cell cleanup succeed, this study shows
that DNA stragglers are enough to cause cataracts.
So normal eye operation depends on the successful
cleanup and removal of construction equipment and blueprints: organelles and
DNA. Science Now tells a little more about these
remarkable lens cells: Even so, these cells arent
simply empty; they house a highly organized network of proteins
called crystallins* that transmit and focus the light
passing through. Any disruption in this
sophisticated scaffolding can cloud the lens,
causing cataracts. (Emphasis added.)
Here is an electron micrograph from
Birkbeck
College, UK showing how the fibre cells in the lens are stacked
in neat rows like lumber with hexagonal edges for close packing.
What an amazing thing a living,
transparent lens is. Did you ever think about this process,
that a sophisticated molecular machine had to be produced from the
DNA library that could chop up DNA into fragments, so that they
could be removed and not obstruct the light path? Undoubtedly
this is not the only enzyme involved in the cleanup job.
Each fibre cell needs organelles and DNA during development,
but they must be cleared away at the right time, and in the right
order before the lens is deployed into operation, or else the
user is denied the wonder of sight. This is just one tiny
aspect of dozens of complex systems that all must work for
vision to work.
Think of an eagle, detecting from high in the air
a fish below the water, and using its visual sensors to accurately gauge its
approach velocity, pitch, yaw and roll in order for it to capture food for the
young in the nest, whose eyes are just opening to the world.
Muscles, nerves, specialized tissues, detectors, software,
image processing, cleanup,
maintenance, lubrication and systems integration are just a few
subsystems that must be accurately designed and coordinated in this,
just one of many such complex sensory organs in the body.
Evolution is a fake fur that gives warm fuzzies to people who think in
glittering generalities.
Those who put on lab coats and examine the details and try to fit
them into an evolutionary history get
cold shudders.
*A National
Library of Medicine paper describes one of these crystallin
proteins: alpha-Crystallin is a major lens protein, comprising
up to 40% of total lens proteins, where its structural function is to
assist in maintaining the proper refractive index in the lens. In
addition to its structural role, it has been shown to function in a
chaperone-like manner. The chaperone-like function of
alpha-crystallin will help prevent the formation of large
light-scattering aggregates and possibly cataract. ... Reconstructed
images of alpha B-crystallin obtained with cryo-electron microscopy
support the concept that alpha B-crystallin is an extremely dynamic
molecule and demonstrated that it has a hollow interior.
Interestingly, we present evidence that native alpha-crystallin is
significantly more thermally stable than either alpha A- or alpha
B-crystallin alone. In fact, our experiments suggest that a 3:1
ratio of alpha A to alpha B subunit composition in an alpha-crystallin
molecule is optimal in terms of thermal stability. This
fascinating result explains the stoichiometric ratios of alpha A- and
alpha B-crystallin subunits in the mammalian lens. (Emphasis
added.)

Fetal Cells Fail to Help Parkinsons Patients 08/28/2003
Brain cells transplanted from aborted fetuses did not help patients
with Parkinsons disease, reports
Science
Now. In fact, for over half the test patients, it had serious
side effects. The test at Mount Sinai School of Medicine in New York,
involving 34 patients, was the second using this method.
Patients were followed for two years, another year longer
than the first test. It failed to help
patients overall and left some with frightening uncontrollable
movements, the article states. Researchers are hoping
embryonic stem cells might work better.
People suffering from Parkinsons disease deserve all the efforts
that science and medicine can provide, but it crosses the ethical line
to take the life of one to help another. A pro-abortion advocate
might argue that its better to use fetal tissue than let it go into
the garbage; after all, people are going to have abortions anyway.
But we have seen that this creates a black market for fetal body parts,
and gives abortionists a veneer of charitable advertising
to their clients; they can claim to a worried mother that her babys
tissues are going to help someone with a debilitating disease.
Whether experimentation with embryonic stem cells or fetal cells,
there has to be a better
way to help Parkinsons patients than cannibalism: i.e., devouring
the flesh of one to nourish another. It is a tragic commentary
on our times that we are even asking the question. Maybe that
will be the next taboo our society will openly debate: the rights of cannibals
to practice their lifestyle, as long as they do it in private,
or for a good cause, or with mutual consent. (Dont laugh; with
the kinds of nuts we see today, nothing is shocking any more.
Its becoming hard to find any subject outrageous enough to be
understood as satire.)
You could almost predict the
voices that would rise up in support of cannibalism:
2010: The Future of Cannibal Rights
First it will be something kinky on Jerry Springer that college students find amusing,
then the practitioners will be seen as victims, who cannot help the way they
were born. Some scientific journal will report a potential health
benefit, and a psychology journal will conclude that it is harmless,
and actually has
positive social effects in some populations.
Someone will find a gene for cannibalistic propensities.
The ACLU will support a test case of cannibalism for medicinal use;
defense attorneys will argue that it is no different in principle from
using fetal tissues or embryonic stem cells for medical treatment.
Cannibal Rights groups will arise, with marches on Washington; these will be
reported compassionately by the media, making people sympathetic for this
new class of the oppressed; the religious right, by contrast, will
be the bad guys. A ranting protestor, who will be labeled a
fundamentalist Christian, will be shown delivering hate speech to a
mild, nicely-dressed cannibal. Commentators will complain
that the members of the religious right always
want to shove their values down other peoples throats
(but some will try to respond that they want to prevent
other material from going down their throats).
The Discovery Channel will sanitize the
history of cannibal societies, portraying them as healthier and better
adjusted than stressed-out, obese Americans; after all, it was
Christian missionaries, whose exaggerated and biased reports gave
cannibals an undeserved negative reputation.
Celebrities, gradually at first, will become more open about their
private cannibalism, from I dont see anything particularly
wrong with it, to I tried it once when I was young, to
Only a bigot would try to stop someone from doing what he or she
feels is best for their own health. Actors will out each
other. Cable companies will offer the Cannibal News Network,
late nights at first, then prime time. This will be followed
by Cannibal History, Cannibal Gourmet and Cannibal Planet.
Slogans like Eat the one you love and You
are what you eat will be seen on backpacks and locker doors of
public school children, who will have
attended required presentations by visiting cannibals brought in to
describe their lifestyle under the banner of diversity and sensitivity.
Nose bones will become chic on campus.
Pretending to gnaw on anothers
arm will be funny at first, then a sign of affection. Laws will
by then have incrementally reduced penalties for cannibalism except in
the most violent cases. Readers of best-sellers will be shocked
at first, then amused, at great historical figures that were alleged
to have had cannibalistic tendencies.
Cannibals will take on a new label,
Sweet, to overcome any lingering prejudice about cannibalism.
Sweet Rock will become the hottest trend in music.
Some over-zealous right-winger who cant take it any more will bomb a
Sweet Barbecue, and this will become a cause celebre for the
Sweet Rights movement. There will be no end of replays on TV
of the shocking incident (the cameras will avoid, however, scenes of
looters picking up on all the newly-distributed body parts).
In response to this deplorable act, harsh
new laws will be enacted against those who protest or obstruct Sweet
events. Conservative politicians will get nowhere
unless they express moderation on the Sweet Rights controversy
and support cannibal privacy laws. It will be considered
marginally tolerable for a conservative to say, Well, though
I disapprove of the practice myself, Im not one to judge what
someone does in the privacy of their own home.
Liberal politicians and celebrities,
on the other hand, will be grand marshals at the Sweet Pride Parades.
The U.N., with a strong contingent of
representatives from cannibal countries, will have been harshly
criticizing America for years on this issue. Europeans will
wag their heads at how intolerant the Americans are, and some will refuse
to do business with the U.S. until it grants full civil rights to the
Sweet People. Finally, the Supreme Court
will find a right to cannibalism in the Constitution, and it will
become a hate crime to speak out against it.
Supermarkets of the future will be
amply stocked with Sweet products, attractively packaged,
USDA-approved, and microwave-ready. Public service announcements
will encourage partakers not to use black market products, which might
contain disease, but only to
purchase through legitimate approved sources, including flesh farms
where genetically-modified (GM) brainless bodies are grown under sanitary
conditions, and clinics where volunteers can submit their bodies
for consumption. The benefits of clean
cannibalism will be advertised: recycling, less need for valuable
cemetery land, and healthy spare organs for those on waiting lists.
Consumers will feel a little
better if they see labels certifying that the contents contain
no leftovers from Christian executions in totalitarian countries.
Though everyone thinks bigoted reactionaries are deplorable and deserve
condemnation, capital punishment is still taboo among civilized societies.
Beware of sweet-talking advocates who insist that cannibals should
have the right to do whatever they want with your own body.

OK, we have to lighten up this grim discussion with a
cannibal joke. In a New Guinea cannibal deli, a tourist was
intrigued by the menu. It read, Special today: fresh brains!

criminal brain, $5/lb, grad student brain, $7/lb, PhD brain, $10/lb,

Quantum Gravity Theory Fails Observational Test 08/28/2003
Studies of gamma rays from distant galaxies and from the Crab Nebula
have put the kibosh on theories of quantum gravity, reports
Science
Now.
These theories predicted that space and time arent
smooth at the smallest scale, but fuzzy and foaming. Those hopes
have been dashed by two independent measurements of cosmic gamma rays,
which show that Einstein was right after all--and that current plans to
detect the quantum foam of spacetime should fizzle.
The tests involved looking for violations of Lorentz
invariance in gamma rays from these sources. What is the upshot
of these observational tests? The results sink several
quantum gravity theories, including some that predict the universe has
extra, as yet undiscovered dimensions.
The article includes the well-known picture of Albert
Einstein sticking out his tongue, as if saying, Nyah, nyah!
to his critics. Einsteins special relativity holds,
so quantum gravity remains undetectable.
Stephen Hawking has made much of quantum
gravity theories, and some cosmologists have suggested that the quantum
foam nature of spacetime led to a fluctuation that gave birth to
our universe. Hugh Ross has made a big deal out of extra cosmic
dimensions. Well have to see whether these findings produce
cosmic deflation of these ideas.

Mars and Neanderthals 08/27/2003
With Mars closer to Earth than any time in the last

Attack of the Clones 08/27/2003
Three pig clones dropped dead of heart attacks suddenly,
before they reached six months old, reports
Nature
Science Update. These incidents point out that most
scientists rule out reproductive cloning of humans as inherently
dangerous, the article says, but still views therapeutic cloning
to grow tissues and organs as safe.
We are told that therapeutic cloning is a safe, effective operation on
embryos: Here they extract cells from early human embryos, which
can be selected or treated to ensure they are healthy.
Yet researchers found it totally shocking that their pig
clones died suddenly. The article states, Researchers
have already genetically engineered partly humanized pig cells and
then cloned them to make whole pigs, whose organs might avoid
rejection by human recipients. It may raise concerns,
says [Jerry] Yang, who watched his pigs collapse and expire.
Some scientists attempt dangerous and unethical experiments just because
they can, and often just because they want to be first.
Undoubtedly many are motivated by a sincere desire to alleviate human
suffering. But is it justifiable to kill a pre-birth human so that an
post-birth human can live longer? Most scientists are repulsed by
human cloning at this time, but that could change.
Does anyone trust their ability to police themselves?
Science, as well as democracy, may need separation of powers and
consent of the governed.

Helping Chemical Evolution Re-Evolve 08/26/2003
The
Whitehead
Institute for Biomedical Research (MIT) has an upbeat article about
chemical evolution, opening with a theme park flavor, complete with
cartoon of a roller coaster. Then it makes a surprising claim
that David Bartel, researcher at the Institute, is building a theme
park in a test tube. The theme of his theme park is explained:
a microscopic theme park whose motif, the origins of life,
is of equal interest to both scientists and philosophers.
His test tubes, filled with RNA micro exhibits, revolve
around an important theme, because
This is one of the most significant and fundamental questions
in science, right up there with `how does the mind work?' or `how
did the universe begin?'
To try to answer the question, Bartel is doing
evolutions job of selecting the fittest out of trillions,
even quadrillions, of RNA molecules. He is re-evolving
evolution, the article claims, by finding the best at forming
bonds with other RNAs, and giving them better odds: Really,
we end up selecting for the survival of the best
molecules, and then propagating those survivors, this is
Darwinian natural selection, according to the David Cameron, author of
the article. (Emphasis added in all quotes.)
Bartels group is proceeding on the RNA World
assumption: the idea that life got its start when RNAs found a way
to replicate themselves, store genetic information, and perform
simple enzymatic processes. So far, however, Bartel has only
gotten his molecules to replicate about 14 bases, much short of the
200-nucleotide goal. Some critics doubt the RNA
World scenario. David Deamer (UC Santa Cruz), for instance,
thinks its inconceivable that RNA could have catalyzed
and evolved outside the barrier of a cell membrane without just
drifting off.
Because of this and other problems, researchers
consider three alternative scenarios:
- Information First: This is another term for the
RNA World view, because RNA could have the ability to store genetic
information as well as catalyze chemical reactions.
- Metabolism First: This idea, in contrast to
the RNA worlds information first thesis, posits
that a chaotic soup of small, random molecules led to
chance metabolic reactions that evolved into modern
cellular life
- Membrane First: This is Freeman Dysons
garbage bag hypothesis. Cameron describes it,
Dyson, a physicist at the Institute for Advanced Studies in
Princeton, N.J., believes that primordial soup was filled with
membranes (garbage bags) that contained random chemicals
not nearly as complex as RNA or DNA. These chemicals began
catalyzing reactions in each other, some of which eventually caused the
cell-like garbage bags to divide and thus evolve.
Each of these theories stresses one prerequisite for incipient life over the
other two: information, metabolism, and compartmentalization.
Bartel agrees that finding a suitable means to package his
precocious RNAs is necessary for the RNA World scenario to work.
Stuart Kaufmann (Santa Fe Institute) argues that the RNA World story
is too narrow; maybe other, unknown molecules were able to copy
themselves without the template base-pairing technique RNA uses.
But Jack Szostak, another RNA World pioneer, cant
imagine a system as complex as cell formation and division not
being preceded by some sort of informational transmission, such as
RNA creating RNA. Maybe there was a simpler precursor
to RNA, like TNA (threose nucleic acid), which has been manufactured,
but unfortunately does not exist in nature.
The disputes between researchers leave Bartel
undaunted. Meanwhile, Bartel and his team continue working
toward their goal of developing an RNA enzyme that can fully
replicate other RNAs, Cameron concludes.
Were designing these RNAs as well as we can,
Bartel says, and what we cant design, we evolve.
The more successful this re-evolving, [the article ends,]
the closer he gets to his theme parks grand opening.
The time has come for Eugenie Scott and her NCSE friends to rise up
and picket this amusement park
in protest. If religion has no place in science,
then fairy tales must also be banned. The time has also come for the
ACLU lawyers to sue the park for misrepresentation. As any lawyer worth his salt knows,
terms must be defined carefully to avoid equivocation and obfuscation.
The readers are being taken for a ride in fantasyland.
Where does one begin with such an article?
First, remove all the silly theme-park metaphors, because theme parks
do not evolve, they are the products of intelligent design.
Nature has no desire nor power to design theme parks, test tube size
or not.
Then remove all the references to test-tube evolution,
because it is not evolution, it is intelligent design again.
Artificial selection is not evolution. It is the application
of the breeders intention, design, purpose, planning, supervision
and guiding intelligence to achieve a desired result. How on
earth can this be re-evolving evolution, when he is
removing products that would otherwise degenerate or be destroyed
by harmful cross-reactions, and giving them an unnatural new lease
on life? Its the same fundamental fallacy
the computer evolutionists
make with their imaginary digital organisms in silico.
Foul! No guidance, no purpose, no goal,
no direction, no supervision, no sympathy, no cheerleading is
permissible in Darwinland. Thats
why Bartels statement What we dont design, we
evolve, should make the judges hit the gong. (Try your hand
at parsing this one: Really, we end up selecting for
the survival of the best molecules, and then propagating those
survivors - Darwinian natural selection.)
The three competing scenarios each falsify the other
two, and point out why chemical evolution is such a farce.
Without a membrane, the lucky molecules are going to just drift away,
as Deamer pointed out. Without metabolism, there is no energy
with which to convey or replicate genetic instructions.
But without genetic instructions (information), there will be no
replication, and no natural selection. Three strikes is
supposed to put them out, but paying no attention to the umpire,
who seems to be out to lunch, they gleefully run a victory lap
around the bases in their scientific lab coats.
The laboratory work is all a smokescreen.
It obscures the fact this is not science, but only materialistic
philosophers playing games with chemicals. Science is supposed to
be about observation, about proving things. Since the origin
of life is a one-time occurrence not subject to observation, evolutionists
could not prove it even if certain interesting reactions occur.
Even if they created life in a test tube (the impossible dream),
that would not prove it happened in that manner in the past.
At todays
NASA briefing about the shuttle disaster, investigator
Scott Hubbard of Ames Research Center pointed out part of the problem
that led to the failure of Columbia. Based on past
successes, the mood among the shuttle operations team had shifted
to prove to me it wont work instead of prove to me
it will work. Because they had become overconfident,
they slacked off, and expected engineers to raise alarms if they
could not prove everything was go, rather than making sure it was.
It was an accident waiting to happen. Similarly, evolutionists
have become lazy scientists. They expect us to just accept their
tales if we cannot prove that it wont work,
rather than their having to prove it will work.
This is the old debate fallacy of shifting
the burden of proof. In his new book
Darwins
Proof (Brazos, 2003), Cornelius Hunter stresses the point.
It is not the job of a critic to disprove evolution; it is the job
of an evolutionist to prove it. When naturalistic philosophy
became wedded to science, evolutionists got lazy. They worked
on the premise that any remotely-plausible just-so story is
permissible, as long as it is naturalistic. They expected
non-evolutionists to disprove them, but its an impossible
task; it amounts to having to prove a universal negative.
How can you disprove a fairy tale?
After all, it just might be true, in dreamland, that
lucky molecules would just come together start evolving.
How could anyone prove them wrong? But it should not
be a critics job to prove them wrong. It should be an
evolutionists job to prove it right.
It is not enough to prove just one tiny piece of the
story right, either. The whole story must work, and in the right
sequence, and be demonstrated without investigator interference.
For instance, suppose I make up a story about the origin of music:
The Meatball Scenario for the Origin of Music
On top of spaghetti,
all covered with cheese, I lost my poor meatball when somebody sneezed.
It rolled off the table and onto the floor; the last time I saw it,
it rolled out the door. Then it rolled down the street, up over
a mountain, down to the ocean and off
the dock, and was swallowed by a fish. After crossing the Atlantic,
the fish was caught in Portugal, and was fed to a cat, who then jumped onto a piano
and spontaneously played a John Cage
chance music composition. From these humble beginnings,
music was on its way to Bach, Beethoven and Brahms.
This story is not so implausible; why, think of all the millions of people
sneezing every second. Think of all the millions of meatballs being
made in homes around the country, and all the fish in the sea and all the
people that have cats. The ingredients of the scenario are all
natural and all readily available; given enough time, it could
happen.
Suppose no one saw the entire sequence of events, but individuals have seen
small parts of it: a cat on a piano, a man sneezing at dinner, and a
species of fish capable of crossing the Atlantic. I make a big
deal of this.
You respond by pointing out difficulties in the story, but I waltz around
them by invoking ad hoc conditions: the meatball made it over the mountain,
because a strong wind came at just the right moment. I publish a
scientific paper examining a gravy spot on the floor that I have
found. Someone else publishes a photograph of a fisherman on a
dock in Portugal. Have we established the meatball theory for
the origin of music?
Suppose also I insisted that you prove my story
wrong. You would be justified in insisting I prove the story
right. No less should we insist that chemical evolutionists
prove their tale, rather than bluff us
into agreeing that this or that
portion of the tale might be plausible, therefore it is up to a critic
to prove it could not happen. The origin-of-music tall tale is much
more plausible than believing that information organized itself, encased
itself in a membrane, and directed energy precisely where needed to
produce life, and thats where we came from.
The article lists only three alternative hypotheses for
the origin of life, all naturalistic.
The fourth one that is never listed is intelligent design.
Yet that is the only explanation that fits our common experience.
Whenever we find an information-rich system, whether a symphony, or a
book, or computer software, we know that an intelligence caused it.
We may not know the designer, or anything else about him or her, but
we can justifiably infer based on the specified complexity of the parts
that it was not the result of chance and natural law.
The reasoning is exactly the same when observing
the information-rich systems in a living cell.
Since intelligent design passes the
test of uniform experience, it is an inference to the best explanation
and therefore deserves to be the default explanation.
If you ever find a theme park created by chance,
dont ride the roller coaster, because its only an illusion
created by stacks of garbage bags.

Nobel Laureates Opine on DNA, Politics, and the Christian Right 08/24/2003
James Watson (co-discoverer of the DNA code) stopped by California
Institute of Technology on May 5,
and had an informal chat onstage with David Baltimore (Nobel laureate
in DNA research, current Caltech president).
The discussion, held before a packed auditorium, was just reported in
Caltechs latest issue of its magazine
Engineering and Science
(LXVI:2, pp. 19-25). Jane Dietrichs report is
entitled, A Conversation with Jim Watson.
In their unrehearsed remarks, they touched on many subjects: the history
of Watson and Cricks discovery, computational biology, the minimum
genome for life, the ethics of genetic screening, pseudogenes, cloning,
aging, the brain, ethics, politics, science policy,
religion, and what it means to be human.
For example:
Watson went on to describe research that had determined that the bacterium
B. subtilis has only about 250 genes essential to life.
He said that in 1965 he had thought of a bacterial cell as
a little machine and tried to figure out how many essential
parts there were. He had guessed there would be about
a thousand parts, or genes. The astounding fact that a
bacterium can have as few as 250 necessary genes made sense, he
thought, because life had to get started. To put
together a thousand, you needed God, but with no God, you can say
at some time it had to be simple.
(Emphasis added in all quotes.)
A theme Watson repeated several times is that the religious right was
holding back the progress of science. For instance, Baltimore
asked Watson, What is the biggest ethical challenge that comes
out of the kind of knowledge were developing today?
I think its that were not using this
knowledge, said Watson. He pointed out that the gene for
fragile X, which causes the most common form of inherited mental
retardation (one in 265 women carries the gene), is known, but no one
is being screened for it. To me, the ethical thing is
were being held back.
Baltimore: Whos holding that back?
Why is it being held back? Is it because of commercial interest?
I think people are afraid to attack the
Right to Life lobby, thats all, Watson responded.
Screening is bad. Screening is Hitler.
But, countered Baltimore, genetic screening is
an opportunity for each individual to decide on for himself
or herself.
Watsons response was that he finds it
troubling that our society is indifferent to continued
genetic disease. There is a conflict between truth
by revelation and truth by observation and experiment.
I think the big fight eventually in our country is not
going to be between Republicans and Democrats, but between
those who think secularly and those who think in
a fundamentalist way.
The audience applauded. You
know which side Caltech is on, said Baltimore.
Watson continued by contrasting people who believe in
religion but dont want to restrict other people
with fundamentalists who want all people to
follow their beliefs. The latter are those, he
thinks, who are hindering the screening for genetic diseases:
I feel very strongly that were failing ethically
by not using the knowledge we have.
Baltimore asked Watson about the 75% of
non-coding DNA in the human genome that is repetitive,
when other species have much less repetitive DNA:
.... Do you think, he asked, thats
a proof that all of that excess DNA really is junk, sort of
a parasitic DNA that only cares about itself?
Its more like 95 percent,
answered Watson. As in the other species,
it looks like theres about 5 percent thats
conserved1 percent are amino-acid-specifying, and
the other 4 percent are useful in regulating when, where,
and to what extent individual genes function.
All human genetic variation resides in that 5 percent, he
said.... While many human attributes wont
have genetic causes, we shall probably be surprised
by the extent that they do.
The reporter noted that Watson profoundly believes that
modern biology is beginning to profoundly affect
how we as human beings live and think about ourselves.
She noted that often he prefaced his candid answers with
disclaimers like I probably shouldnt say this
or this will sound bad but its probably true.
For instance, when discussing stem cells, cloning, genetic
engineering and the public, he again pointed to the usual
suspects who are hindering scientific progress:
You and I and all of our fellow scientists have to
spend much more time with the public and do it over and
over. Were finding out what human beings
are, and most people dont think like us.
He would like to see scientists run for Congress and become
part of the government. Youve got to get
in there. The Christian Righttheyre
in there. And were not.
Other subjects Watson touched on that fit the category
this will sound bad but its probably true
included: whether there is genetic basis for criminal behavior,
and whether we are all created equal, as assumed in our
Declaration of Independence:
Thats why biology really is becoming so
relevant. We have laws based on the fact that
were equal. And were probably not going
to be.
So it is a big issue, having law
that reflects the standards of genetics, commented
Baltimore.
Watson: And no easy solution.
In discussing his rivalries with Linus Pauling, Rosalind
Franklin and others involved in 1950s genetic research,
Watson said he was struck by the 18th-century Scottish
philosopher David Humes belief that humans are
fueled by their passions, not by reason.
In answer to whether science has gotten too
big, Watson answered, Understanding human beings
at the molecular levelunderstanding the
immune response, which is a lot more complicated than
was thought 30 years ago, and the brain
will take an awful lot of people.
They are an
awful lot, are they not.
This conversation is very enlightening, and
a good example of why the public should fear scientists
who think they know what is good for us.
It demonstrates that highly intelligent
people, which Watson and Baltimore certainly are, are unfit
to be our rulers, because they are just as filled with
illogic, prejudice, and shortsighted planning as the rest
of us. These two are undoubtedly polite and respectable
gentlemen in person, and certainly entitled to their opinions,
but look at their opinions: filled with the us-vs.-them mentality,
the either-or fallacy,
loaded words,
oversimplification,
the straw man tactic, and
suggestions that, if not clarified, could be dangerousas
bad as Hitler, or worsedespite Watsons brush-off of the
fears people have. Lets think about some of
the things they said, first the scientific claims, then
the ethical ones.
- Minimal Life: Watsons comment about
250 genes not needing a God was emphasized in a sidebar
in the magazine. Good grief. So 1000 genes would
need a Creator, but 250 would not? What kind of silly
conclusion is that? There is so much information in
even 250 genes, it would
never come together by chance in
trillions of universes.
Watson cannot point to any
self-sufficient living organism simpler than this bacterium
needing 250 genes as a minimum. As we pointed
out in the Aug. 13 headline,
even evolutionists believe that these minimal cells
are stripped down versions of complex organisms, not evolutionary
missing links. His comment goes to show that scientists
can be very skilled and intelligent in their specialties but
utterly illogical in other respects.
Watson admitted that the human brain and immune system are much more
complicated than previously thought. The one who helped
discover coded language at the core of life
should be aware of the tremendous complexity of even a minimal
living cell. He misrepresents reality to imply there
is a sequence from simple life to complex life, so that no
God is required. A scientist should build his opinion
on observed facts.
- Junk DNA: Both Watson and Baltimore equate
unknown function to no function. We reported
May 23 that so-called junk
DNA is turning out to be a treasure mine of functional
information. The term junk DNA was coined by an evolutionist whose
biased nomenclature stymied scientific progress by implying the repetitive sequences
were useless. Baltimore commits the personification
fallacy by calling this genetic information
parasitic DNA that only cares about itself.
Both men also appear bound to the now-questionable Central Dogma, that
DNA is the master control of genetics. Many investigators now
suspect that epigenetic factors may be just as important, if not
more so, in determining inheritance.
- Right to Life lobby: Here Watson indulges in
the either-or, us-vs-them tactic of making bogeymen out of
those who have legitimate concerns
about screening for genetic diseases. Both Watson and
Baltimore portray themselves as benefactors, wanting to
cure cancer and help
the suffering by using scientific knowledge from genetics,
while the Right-to-Life obscurantists scream Hitler!
and stand in the way of progress, as though more interested in
foisting their fundamentalist beliefs on people than helping
mankind. But who is Watson to lecture us on ethics?
Watson vastly oversimplifies the controversy.
Christians, the religious right, the Right-to-Life lobby, the
fundamentalists, or whatever label you want to put on them, do
not constitute the only people deeply concerned about genetic
screening. There are very serious questions to ask before
granting scientists the ethical reins of society.
Of course, any compassionate person would not want to deny a
person with a debilitating genetic disease the hope of a
cure, but we must define our terms. Is depression a
disease? Is criminal behavior a disease? Is an IQ
under 100 a disease? Should an
individual be allowed physician-assisted suicide if he or she has
a genetic disease? Should a couple be permitted to abort an
unborn baby diagnosed with a genetic disease?
Should the state sterilize disease-tainted individuals to prevent
their corrupting the human gene pool (eugenics)?
How do we define quality of life?
Who decides if a person is fit to live, or is a defective?
Are mentally retarded people fit to live? The elderly?
Criminals? Should we take human evolution into our own
hands? Should we breed a fitter race, such as stronger
swimmers and weight lifters for the Olympics? Should the
government breed worker bees, warriors, intellectuals and rulers
for preselected roles in a utopian society, and if so, would a warrior
have any rights to change his role and become an intellectual?
Should we breed chimeras,
just because we can? Should
couples be given the right to select the sex of their children?
Is it right to
do wrong to have a chance to do good? Should an individual
be put to death so
that another can live? Should we grow
brainless adults to harvest their organs for those needing them?
What is the difference between that and growing clones or stem
cells for the same purpose? When does genetic research
cease to be compassionate medicine, crossing the line into
playing God?
These are just a few of the serious questions that
must be faced, and scientists are definitely not the only
ones to answer them. In fact, as ethics author and lecturer
Dennis Prager
has emphasized, experts should be the last ones to make
the decisions, because they are too close to their special interests.
Scientists can provide valuable information
to the policy makers, yes, but woe to the society that lets them make
the ethical decisions. Scientists often fail to
see the big picture, to understand history, and
to foresee the implications of their views. Watson implies
that we should screen people for a gene that causes mental retardation,
but then what? Should these people be allowed to marry, or
should they be forcibly sterilized
against their will or knowledge, as actually happened to
20,000 victims in the
United States during the eugenics fad? Where would Watson
draw the line on Hitlers experiments, some of which were
well-intentioned on sincerely held scientific beliefs?
We cannot forget history to see how ugly an
unrestrained science can become.
- Truth by revelation vs. truth by observation:
This makes sense, when you dont think about it.
Watsons comment presupposes that both religion and science
claim to provide exhaustive knowledge.
If God had told us all about DNA and retrotransposons, I suppose
it would make sense to believe the Expert, but the Bible is a
condensed book. There is a lot it does not talk about, and
God gave man the freedom and intellect to search out
many things. Conversely, science is incapable of investigating
some very large and important domains: history, aesthetics,
ethics, values, morals and ultimate destiny among them.
Neither source of information is exclusive nor exhaustive.
Watson commits the
either-or fallacy by implying that no person who believes in
divine revelation could ever be a scientist (see our
online book for a refutation), and that
science is a path to ultimate truth. He wrongly presupposes
that scientists can be objective and neutral regarding everything.
- Fundamentalists and proselytizing: Watson
tolerates religious people who dont want all people to
follow their beliefs. Presumably, such believers dont
take their beliefs too seriously. Watson, however, is quite
fundamentalist about his scientism. He thinks scientists
need to run for Congress and impose their beliefs on the rest of
us: such as, how to think secularly, and the belief that
we are not created equal, in fact, we were not created at all.
Watson badly misinterprets the Declaration of Independence clause that
we are all created equal, hinting that biology says
we probably are not. The Founding Fathers
had eyes. They knew people differed radically in size, shape,
physical and even intellectual capacities. The point was that
they are endowed by their Creator with certain inalienable
rights; i.e., all people have equal worth, and each individual must be
treated by the government without partiality. To claim
otherwise is an invitation to tyranny, and science can make no
such claim. A tyranny of scientists
could be the worst of all.
David Hume was not always right, but aptly observed that at least
some humans, even some scientists, are fueled by
their passions, not by reason.

Nature Believes in Biblical Flood? 08/22/2003
Nature
Science Update posted a story about a hypothetical geological
model that may have explained the Biblical flood, and
even quotes Genesis 7:11 on a sidebar: All the fountains of
the great deep burst forth and the floodgates of the heavens were
opened. But before presuming the British science
journal has got religion, it should be noticed that the article is
focused more on a particular geologists explanation for the
Permian extinction that supposedly wiped out most living things
250 million years ago.
Considering this new idea wacky, but not so
wild that it shouldnt be taken seriously, the article
presents Gregory Ryskins hypothesis that huge volumes of
methane, trapped in frozen methane clathrates in the sea, were
released into solution over aeons, then suddenly belched
by a catastrophic event, like an asteroid impact. This might
have released 10,000 times the energy of the worlds nuclear
arsenals, leading to mortality on a massive scale.
If it happened once, it could have happened periodically
on a smaller scale, such as in the Black Sea 7,000 years ago
thus the Biblical flood.
Nature, of course, is more
interested in the evolutionary story of the wipeout of most of life
millions of years ago. Any similarities to a religious
myth dating back just a few thousand years are incidental
in their sophisticated, scientific opinion. It makes
a nice sideline for the occasional religious reader, perhaps.
There are two kinds of people who get interested in
natural explanations for Biblical miracles: (1) those who deny
the Bible, and believe that naturalistic events became entwined
in ethnic legends, as here; (2) those who believe the Bible, and think
that a natural explanation will make the story more palatable to the
public. Though well intentioned, these interpretations tend to
diminish the sovereignty of God, and often play loose with the
Biblical record. Undoubtedly, God could steer natural events to
accomplish His purposes, and a miracle would involve natural phenomena.
But in this case, the flood was not restricted to the Black Sea area,
and it was not due to a belch of swamp gas. According to Genesis,
God brought it about supernaturally by His definitive act, as judgment
on a world that was filled with violence, in which
the wickedness of man was great in the earth, and that every
intent of the thoughts of his heart was only evil continually
(Gen 6).
Sound familiar?
Get ready.

Science Gives One-Sided Brush-off to ID 08/21/2003
In Science
Aug 21, Robert Pennock reviews Michael Ruses latest book
Darwin and Design (see June
12 headline). He compares it with the 19th-century Bridgewater
Treatises, a set of 19th-century monographs by Christians explaining
evidence for God in the sciences. Now, the Templeton Foundation
has funded a set of seven books on science and religion, of which
Ruses book is the first. Pennock likes it a lot and think
it has set a high standard that will be tough to match. It covers
everything from the history of natural theology and design arguments
to the modern Darwinian synthesis, which leaves no more place for
a Designer:
He also has a helpful way of organizing
the conceptual analysis of the design argument, separating the argument
to adaptive complexity from the move to a designing mind. Ruse
clearly explains how Darwinian evolution blocked that second
move, by providing the answer to the question of biological
purpose: Natural selection produces artifact-like features, not
by chance but because if they were not artifact-like they would not
work and serve their possessors needs. The language
of intentional design now serves only as a handy metaphor.
Both Pennock and Ruse think it is possible to be
awestruck at the appearance of design in nature without being religious:
We have learned much in the two centuries since Bridgewater, and Ruse
shows that natural theology is no longer viable. However, he does
not disparage the impulse that led to it. There is indeed awe to
be found in biological adaptations, which might be expressed in a new
theology of nature that appreciates the complex,
adaptive glory of the living world, rejoices in it, and trembles before
it. He quotes Mayr, who once told him, People forget
that it is possible to be intensely religious in the entire absence of
theological belief.
But both Pennock and Ruse only have time for a dismissive sweep of the
modern Intelligent Design movement:
Ruse quickly dismisses the recent attempt to resurrect
Paleys argument by Intelligent Design creationists such as
Phillip Johnson, Michael Behe, and William Dembski; they warrant
only a brief discussion in the final chapter. Ruse reviews
and extends some of the many arguments that have been given against
Behes irreducible complexity, Dembskis
explanatory filter, and appeals to the purported problems of
complex specified information and the no-free-lunch
theorem. Behes view, he concludes, is pure and simple
fantasy; Dembski is just plain wrong; and their
Intelligent Design movement is already regarded, even by theologians,
as an embarrassment.
Pennock calls his review A Bridgewater Treatise for the
21st Century. The book is:
Darwin and Design: Does Evolution Have a Purpose? by
Michael Ruse (Harvard University Press, Cambridge, MA, 2003).
The comebacks are never heard in Science, because the
microphones point in only one direction. Johnson, Dembski, and Behe have
a lot to say in rebuttal (read their books), but the
Darwin Partys tactic, as here, is to brush them off quickly,
as if to say, Dont read their works; you dont
need to, because our Goliath already did it for you.
Its the argument from
authority in a journal that is supposed to be about open-minded
investigation of the facts.
Pennock should have been highly
suspect at Ruse for stooping to ridicule
like calling Behes work pure and simple fantasy or
sidestepping issues and
using glittering generalities
such as summing up Dembskis long and detailed arguments as
just plain wrong, or appealing to peoples
herd instinct by saying that
their work is already regarded, even by theologians [My, O my]
as an embarrassment. Is such blather to be respected
as the honorable and recondite analysis by Darwinisms greatest
living philosopher? Suppose Dembski did that, and instead of
writing two detailed, mathematical tomes, sent Science a
short postcard saying, Y'know, Ruse is just plain wrong.
His ideas are pure and simple fantasy. Everybody thinks they are
an embarrassment. And suppose
Science printed it? Thats about how fair these
Darwin Party journals are when it comes to seriously analyzing the
important issues in philosophy of science today.
Ruse and Pennock dont
want readers of Science to think. They just want them
to swallow the opinions of The Authorities. Ruse said ID is
fantasy. End of story.
You have to know their opinions are weak when a schoolboy
could see right through them. Take a look at the monumental
conclusion about the argument from design that Pennock feels Ruse has
deftly dealt a death blow: Natural selection produces artifact-like
features, not by chance but because if they were not artifact-like they
would not work and serve their possessors needs.
Are you impressed? So this is the best Ruse can come up with
(assuming Pennock, an admirer, accurately encapsulates the argument).
This is no answer at all. Its the same cop-out the
Anthropic Principle argument uses to fail to explain design:
Well, silly, if it werent that way, we wouldnt
be here worrying about the question. Good grief.
Ruse and his disciples have not explained the design of an eye, an
ear, a wing, or anything else. They just say if it were not
well adapted, it wouldnt be there. Newton and Maxwell
would be embarrassed by such shallow reasoning.
Whenever evolutionists really attempt to explain
design in detail, they give up in utter frustration (see
yesterdays headline). Natural selection
is impotent to explain the origin of any complex structure
except without copious additions of imagination and faith, and
yesterdays story essentially said so.
Science is supposed to rest on evidence.
OK, evolutionists, put up or shut up. And if you have your own mind,
read Behes and Johnsons and Dembskis books,
instead of leaning on the one-sided opinions of the Darwin Party.
Another challenge: name one instance of complex specified
information, anywhere, that is the product of unintelligent,
unguided, undirected natural law or chance, or combination of the
two, including natural selection (The Rule: it must be supported
by observational evidence, not just-so storytelling).
Another example of the shallowness of their thinking
is this idea you can be in awe of natures designs without being
religious. To be consistent, they would have to believe that
awe evolved like everything else. What survival value does
awe have? Why are we moved by the good, the true, and the
beautiful? Natural selection cannot provide answers to these
questions: they point to a conscience, and an innate knowledge
of purpose and morality and order that no naturalistic philosophy
can expunge. Thats why Pennock and Rose propose an
alternative theology of nature so that their God-shaped
vacuum has something to bow down to, and tremble before.
When a mans awe becomes detached from the
Creator, it attaches instead to the creation, fulfilling the
Apostle Pauls prediction, professing themselves to
be wise, they became fools.... they worshipped and served the
creature, more than the Creator, who is blessed forever
(Romans 1:20-25).

No Martian Oceans 08/21/2003
In a news bulletin sure to be disappointing to those envisioning
an ancient Mars with oceans brim full of life, the
Jet Propulsion
Laboratory announced today that Mars shows no evidence that
large bodies of water existed in the past.
For six years since its arrival at Mars, the
Mars Global Surveyor
thermal emission spectrometer has been looking for signatures of
carbonates (like limestone), on the surface.
Oceans would have left outcrops high in carbonates, but none have been
found only a general,
low-level measurement that probably is due to atmospheric water
interacting with the ubiquitous dust.
According to Phil
Christensen, infrared specialist, This really points to a cold,
frozen, icy Mars that has always been that way, as opposed to a
warm, humid, ocean-bearing Mars sometime in the past.
The news report has the pessimistic title, New Findings
Could Dash Hopes for Past Oceans on Mars.
The original paper is published in
Science
Aug. 21.
When
Mars Exploration Rover Spirit
arrives in Gusev Crater in January, it will also look for evidence that
surface water once was abundant at that location. There are still
apparent river channels and stream beds to explain, and possible evidence
of shorelines. The lack of carbonates is disappointing to a wet
Mars scenario, but not conclusive. Wet or dry, though, Mars is a
terra incognita just becoming known to us, as was the far west
in the days of
Lewis and Clark. These are great days of discovery.
NASAs recipe for life, however (dirt + water),
doesnt work. We tried it, and all we got was mud.

Understanding Cells: Think Information, Logic Circuits 08/21/2003
The Concepts article in
Nature 08/21/2003
is about Systems biology: Understanding Cells by Paul Nurse.
A striking feature of his article is the repeated use of the word
information:
Many of the properties that characterize living organisms are also
exhibited by individual cells. These include communication,
homeostasis, spatial and temporal organization, reproduction, and
adaptation to external stimuli. Biological explanations of these
complex phenomena are often based on the logical and informational
processes that underpin the mechanisms involved....
Most experimental investigations of cells, however, do not readily
yield such explanations, because they usually put greater emphasis on
molecular and biochemical descriptions of phenomena. To explain
logical and informational processes on a cellular level,
therefore, we need to devise new ways to obtain and analyse data,
particularly those generated by genomic and post-genomic studies.
An important part of the search for such explanations is the
identification, characterization and classification of the logical
and informational modules that operate in cells. For example,
the types of modules that may be involved in the dynamics of
intracellular communication include feedback loops, switches,
timers, oscillators and amplifiers. Many of these could be
similar in formal structure to those already studied in the
development of machine theory, computing and electronic circuitry.
Nurse identifies three types of information seen in cells:
sequence data, interaction data, and functional data.
He feels that this logical, informational approach to the study of
cells will be more productive than just studying the individual
molecules in detail:
A useful analogy of what is being proposed is the analysis of an
electronic circuit. Once the detailed operations of
different types of electronic components have been identified, it is
possible to gain insight into what an electronic circuit can do simply
by knowing what components are present and how they are connected, even
if their precise dynamic behaviour has not been determined. The
various logical and informational modules implicated in a
biological phenomenon of interest have to be integrated in order to
generate a better understanding of how cells work.
Paul Nurse feels that this information-theoretic approach to the cell
could generate a great deal of experimental work.
The identification and characterization of these modules will
require extensive experimental investigation, followed by realistic
modelling of the processes involved, he predicts.
Such analyses would allow a catalogue of the module types that
operate in cells to be assembled.
But this approach will work only if there is a finite
set of such modules:
The success of this general approach depends on there being a limited
set of biochemical activities and molecular interactions that together
can solve the myriad logical and informational problems found in
biological systems. If there is only a restricted set of
processes that are efficient and stable in operation and which have
been exploited by evolution [sic], then there should be only a limited
set of possible solutions to real biological problems. Of course,
if nature shows no such restraint [sic], then we must go back to the
drawing-board if we are ever to understand its complexity.
Paul Nurse is at the Cell Cycle Laboratory, Cancer Research UK,
Lincolns Inn Fields, London.
Two things stand out from this
article: (1) The cell only makes sense when approached in terms
of information and logic, and (2) An information-theoretic
approach generates productive research.
The intelligent design (ID) community has been stressing
these points for some time, but here the same thing is being stated
in Nature, the most prestigious science journal in the world.
We have no inside clue on the beliefs of Paul Nurse, his feelings about
ID and the origin of life, but this could have been written by Paul
Nelson, a leader in the ID movement except for that one
fly-in-the-ointment personification
fallacy line about the efficient processes that have
been exploited by evolution. That line is so out of
character with the rest of the article, one wonders whether Nurse had
to insert it to get it past the censors. It adds nothing.
It looks like an obligatory pinch of incense to Emperor Darwin.
The thrust of the article is that information
is the key to understanding and the key to research. Opponents
of ID falsely criticize that a design-theoretic approach brings
science to a screeching halt. God did it, and that settles
it! Nature has just printed this refutation,
showing that the opposite is true. Everybody knows that
feedback loops, switches, timers, oscillators and amplifiers
are the products of intelligent design. When we see similar
functions in biological systems to those we understand in electronic
circuits, doesnt it make sense to study them from a design
perspective? Wouldnt that provide the scientists with a
fruitful enterprise? Yes unless cells turn out to be
even more complex, too information-rich for our analogies with
man-made circuits. Then, the only sensible approach would be to
look for deeper design, not chance!
ID is going to save biology from implosion.
Poor Charles Atlas Darwin just cant hold up the world
any more. If you are a scientist worried about ID, fear not.
ID will liberate science from a suffocating 19th-century ideology that
didnt know about information and logic modules at the fundamental unit
of life. You can publish your scientific papers in a secular style
without needing to say the G word. Everything will remain the
same, except for some blessed subtractions: the removal of useless,
foolish references to chance and Mother Nature, the tinkerer.
Instead of having to tow the line of the Darwin Party, you can look
at life in a new way, and it will make sense. As Paul Nelson stated in
Unlocking the Mystery of
Life, science becomes this enormous puzzle-solving expedition,
in which you can expect to find rationality and beauty right at the
heart of things. It will be the beginning of another golden age
of scientific discovery.

Darwinists Fumble on the Evolution of Complex Structures 08/20/2003
If Ronald Reagan had said, communism isnt working,
it would not be news. But when Gorbachev said, communism
isnt working, it was history book material.
Similarly, when Darwinists writing in a Darwinist-friendly scientific
journal say that evolutionary theory isnt working to explain
one of the most important problems that had stumped Darwin, it is an occasion
that should arouse the world news media for a press conference, replete
with anxious reporters asking hard-hitting questions. Yet you
probably will not hear about it except right here; the
admission is hidden away in a Dispatch in the Aug. 19 issue of
Current Biology (emphasis added in all quotes):
A central goal of evolutionary biology is to explain
the origin of complex organs the ribosomal machinery
that translates the genetic code, the immune system that
accurately distinguishes self from non-self, eyes that
can resolve precise images, and so on. Although we understand [sic]
in broad outline how such extraordinary systems can evolve by
natural selection, we know very little about the actual steps
involved, and can hardly begin to answer general questions about the
evolution of complexity. For example, how much time is
required for some particular structure to evolve?
In their article, Nick Barton and Willem Zuidema (Univ. of Edinburgh,
where Darwin attended for awhile), admit that traditional biological
approaches (like population genetics) for explaining the evolution of
complex structures have not worked:
Complex systems systems whose function requires many
interdependent parts are vanishingly unlikely to arise purely by
chance. Darwins explanation of their origin is that natural
selection establishes a series of variants, each of which increases
fitness. This is an efficient way of sifting through an enormous
number of possibilities, provided there is a sequence of
ever-increasing fitness that leads to the desired feature.
To use Sewall Wrights metaphor, there must be a path uphill
on the adaptive landscape.
The crucial issue, then, is to know [sic] what
variants are available what can be reached from where and
what is the fitness of these variants. Is there a route by
which fitness can keep increasing? Population genetics is not
much help here. Given the geometry defined by mutation and
recombination, and given the fitnesses, we can work out how a
population will change, simply by following the proportion of different
types through time. But understanding [sic] how complex
features evolve requires plausible models for the geometry of
the adaptive landscape, which population genetics by itself does not
provide.
The authors point to artificial life models like those of
Lenski and Adami to provide some hope for a solution to the
evolution of complex structures. They describe some of the
apparently complex functions that digital organisms arrived
at, when set free to evolve in simulations according to simple rules
designed into the program. Though encouraged by these, Barton
and Zuidema are not entirely impressed:
Artificial Life models such as Lenski et al.s
are perhaps interesting in themselves, but as biologists
we are concerned here with the question of what Artificial Life can
tell us about real organisms. The difficulty in
answering this is that much work in this field is rather isolated
from traditional evolutionary biology.
While hopeful that synergy between biologists and computer programmers
might provide mutual insights, they have doubts that the computer
organisms have any connection to the real world.
In population genetics and evolutionary game theory, we design
models to study the success and failure of a predefined set of
traits or strategies in the struggle for life.
But what are the possible traits? And how well do
they succeed in particular environments with particular competitors?
These questions are ignored in traditional models they come
in as parameters to be provided by developmental biology and
ecology. For understanding the evolution of complex traits
this is not satisfactory, because these parameters are themselves
shaped by evolution [sic]. Evolutionary processes constantly
shift the targets of evolutionary optimization [sic], create spatial
patterns, turn competitors into mutualists and create new levels of
selection. Artificial Life models of such phenomena ...
promise to be useful for developing the concepts and
techniques to deal with that challenge, but only if they are
combined with the insights from almost a century of population genetics.
The Dispatch is entitled, Evolution: the erratic path towards
complexity, by Nick Barton and Willem Zuidema.
If you have sifted these statements
for any evidence for evolution, or realistic explanations for
the evolution of any single complex system, you have undoubtedly found all
chaff and no grain. Its all emptiness and futility, wishful
thinking, models that are too complex to relate to the real world,
leaning on broken reeds, trusting in others work that never gets
delivered, and vaporware on back order.
Yet this is the theory that is so obviously a fact that anything
else is pseudoscience that must be shielded from students?
This is the greatest idea anyone ever had, so intuitively obvious
that it has taken over the world as the encapsulation of all
that is certain about nature? This is the theory that should
no longer be called a theory, but a fact like gravity?
We hasten to make clear that Barton and Zuidema
are evolutionists, and did not write this article to in any way
claim that they doubt Darwinian evolution. But that is what
makes their admissions so damaging. If Henry Morris had said this,
no one would pay attention, because he (presumably) has an axe to
grind and an ulterior motive. But these guys just gave away
the store. They admitted that after all these years, the
Darwinists are no nearer to explaining the origin of an eye, or
dolphin sonar, or butterfly wings, or immune systems, than Charlie
himself was in 1859.
Notice how they look yearningly, hopefully
to the computer programmers
to provide some relief to the befuddled
population geneticists (with their crude models built partly
on the personification fallacy
of game theory),
but then turn right around and criticize the
programmers for not being realistic, and ignoring the insights
from almost a century of population genetics.
Its like a cartoon character in quicksand calling another guy in the
same quicksand for help. Does anyone see anything solid that
any evolutionist is standing on, that should give Eugenie Scott of the
NCSE confidence in the righteousness of her crusade
to keep evolution the sole contender in the public schools?
The arrogance of the Darwin Party, given admissions like this one,
is astounding.
Barton and Zuidema claim that biologists
understand evolution in broad terms, just not in the details.
But they cannot even begin to point to any plausible series of
steps on the fitness landscape that would allow a mindless organism
to climb uphill to an adaptive peak
to evolve an eye, or a brain, an immune system, or any other
complex feature, when every
step in the imaginary sequence (for which there is no fossil
evidence) would have had to provide enough survival value
to make it triumph over all competitors, such that every organism
without the lucky trait would have died out (this is called
the cost of selection). They admit these complex systems
are extraordinary. They admit they are
irreducibly complex
(in their words, systems whose function requires many
interdependent parts).
They admit that the probability of getting any complex system by chance is
vanishingly small. They admit Darwins explanation,
to be efficient at sifting through the enormous possibilities, is
provisional on the requirement for a sequence of plausible intermediates,
each one needing to increase the fitness of the organism (but how efficient can
that be when there is slippage on the
treadmill due to indirect genetic effects?).
They are utterly clueless how long it would be expected to take for
the slight, successive modifications to add up to a
complex system. And yet
complex systems are the rule in biology, not the exception!
(See todays headline on sponges
for an interesting example.) They claim they
understand the broad outline of how such extraordinary
systems could evolve by natural selection, then two phrases later,
they admit
we can hardly begin to answer general questions
about the evolution of complexity. About face!
(Speaking about faces, they are pretty complex systems, too.)
We joke about car engines held together with bubble gum,
rubber bands and popsicle sticks. Darwinism is like a shiny
sports car advertised to the world as the hottest thing since
religion went out of style. Just dont lift up the hood.

Time to Revise Geology Textbooks Again 08/20/2003
A textbook case of tectonic plate movement is wrong, admits
University of Rochester News.
The Hawaiian Island chain is not the result of plates moving over
a stationary hotspot, apparently (see also
April 1 headline).
It now looks like hotspots can move around:
Mobile magma plumes force us to reassess some of our
most basic assumptions about the way the mantle operates,
says John Tarduno, professor of earth and environmental sciences at the
University. Weve relied on them for a long time
as unwavering markers, but now well have to redefine
our understanding of global geography.
(Emphasis added.) The original paper is published in
Science
Aug. 21.
Pretty strong words. Wonder what
other basic assumptions involving global understanding
that they have relied on for a long
time are due for reassessment. If anything comes up
that calls evolution into question, it will most likely be shot down
and declared unconstitutional.

Superior Fiber Optics From a Sponge 08/20/2003
A deep-sea sponge has been found to have flexible glass fibers
that conduct light better than artificial fiber optic cables
manufactured for telecommunications. The story in
Yahoo News
says that the sponges incorporate sodium into their structures,
which humans are unable to do because of high temperatures that
are required during manufacture. As a dopant, the sodium
gives the sponges
fibers such flexibility, they can be tied in a knot without breaking.
The brittleness of man-made fibers reduces their usefulness in
some applications, so engineers will probably be very interested in
finding out how the sponge accomplished the feat at ambient
temperatures. The sponges spicules are about the same size,
and made of the same basic glassy material, as artificial fiber optic cable,
yet the sponge builds it by means of proteins directed by DNA.
The authors of the paper in
Nature Aug 20
consider the function of these structures for the sponge, which is
known by the nickname Venus flower basket:
Our results suggest the intriguing possibility that the spicules
of Euplectella, beyond structural anchorage support, could
also provide a highly effective fibre-optical network, which may
be useful in distributing light in its deep-sea environment
(emphasis added).
Biomimetics, meaning life-imitation, is an active new
field of research, in which scientists and engineers go prospecting for
living things that have solved complex manufacturing problems.
This sponge is a good example. One scientist commented,
Its such a wonderful example of how exquisite nature
is as a designer and builder of complex systems.
We can draw it on paper and think about engineering it but
were in the stone age compared to nature.
No mention of evolution in the
article: thank God. For other articles on biomimetics,
see the brittlestar with superior
glass lenses (studied by the same scientist at Bell Labs who
led this research on the sponge),
spider silk, the
ideal material, gecko tape and
other stories under the category Amazing.

Darwinians Plot Counter-Reformation Against I.D. Movement 08/19/2003
The August issue of BioScience
contains two articles specifically directed at combatting creationism and
the ID (intelligent design) movement. In a Washington Watch
column, Robert E. Gropp reports on a recent activists summit
attended by 50 science education advocates, clergy, educators,
scientists, and representatives of national organizations which was
co-sponsored by the National Center for Science Education (NCSE) and the
California Museum of Paleontology. In his report, Evolution
Activists Organize to Combat Pseudoscience in Public Schools, Gropp
says the occasion gave advocates a chance to share information and develop
strategies to ensure evolution teaching is unscathed.
Another article by Randy Moore, Murray Jensen, and Jay Hatch
is entitled, Twenty Questions: What Have the Courts Said about the
Teaching of Evolution and Creationism in Public Schools? It
is designed as a FAQ (frequently asked questions) resource to provide
talking points for teachers and other advocates needing to answer the questions
students bring to the science class.
We have a suggestion. Evolutionists should
run their articles by English teachers, logic professors and ethicists before printing
them. Unfortunately, after all the instances of propaganda, illogic and hypocrisy
were red-lined, very little of substance would remain.
Most look back at
Martin
Luther as a brave, lonely man who did
the right thing when he refused to recant the beliefs of his conscience, saying,
Here I stand; I can do no other. God help me.
What followed was a Reformation that many historians, even some Catholics, admit
was justified more or less, because the church, that lowly, persecuted band of
disciples of Jesus who had started as humble seekers after righteousness,
peace and joy in the Holy Spirit, had grown into a corrupt institution,
wedded to tradition and political power. It had drifted so far from
its roots that it was deeply involved in evil practices diametrically
opposite the teachings of Jesus, things like extortion (through the sale
of indulgences and confiscation of property), invention of unbiblical
doctrines, and even sexual promiscuity among priests.
But the Reformation was not won in a day, not by a long shot.
A Catholic counter-reformation followed and both sides
engaged in everything from intellectual debate to warfare.
Unquestionably, there were excesses and atrocities on both sides.
But the motivation to reform what had become corrupt is generally seen as a good thing.
Luthers
95 theses are a classic of
logical and ethical argument against
illogic and corruption. Of course Martin Luther did not act alone.
He is representative of many reformers (Grosseteste,
Jan Hus, Wycliffe, and many more) who saw a problem and tried to fix it.
Some paid with their lives.
Because Luther got the right help at the right time, he just became the most
successful at effecting lasting change.
Neither side won a complete victory. There are still Catholics and Protestants
today, often engaging in combat both civil and militant. Though some strong
voices seek harmony at the expense of doctrine, it would be impossible to maintain
the integrity of the Reformation through compromise.
Maybe that is what is happening in the sciences.
The parallels are striking.
Science, once the common mans quest for truth, has become Big Science,
supported by politicians, with millions of dollars of funding at stake.
Evolution has become the state religion. Thomas Huxley took the sign of the Darwin
Fish and envisioned, In this sign conquer, and wedded evolutionary philosophy
to political science. This unholy alliance produced the corruption we see today,
where any convoluted just-so story gets published and praised,
as long as it has the Darwin imprimatur.
There have been calls for reformation within and without the church of Darwin
for a long time, and every time, the Darwinist apologists resort to the same
tactics to crush it, as seen in these papers.
(Theistic evolution is not a satisfying compromise, because it usually
sacrifices theism on the altar of Darwinism, and fails to explain why God
would have any more involvement than the Deistic god, if evolution is
so effective. As a result, theistic evolutionists usually get
hammered by both sides.) Maybe what is going to
result, instead of one side winning, is a huge schism: the science of the
Darwin Party and the science of the Design Party, the latter being the Reformers
who want to take science back to its original empirical roots,
and the former mounting a protracted Counter-Reformation and a Thirty Years War.
One could hope against hope that somewhere, somehow, cool heads
would prevail and look honestly at the data to see which side fits the facts
better. That would be as idealistic as a Protestant wishing a Catholic
would calmly sit with him and see what the Bible really teaches.
The Catholic would only rarely be won over by that approach, because to a
Catholic, the Bible is no longer the authority: the Church and tradition have
equal authority. So both sides will argue past each other unless they
can first agree on where the authority lies. Similarly, the Darwinists
will never be content to simply look at the raw data and see whether it shows
evidence of design, because they have re-written the definition of science
such that facts no longer matter of themselves. The facts must be
interpreted through the filter of naturalistic tradition and submit to the authority
of Big Science. The modern-day casuists win by default, because
science is naturalism by definition. Anyone who disagrees
simply does not understand the nature of science.
He is an outsider, who cannot show the official imprimatur, and therefore
is rejected out of hand as a dangerous heretic.
Because The Church was the only authority that could
take seemingly contradictory Biblical passages and interpret them properly,
it was necessary to keep the Bible out of the hands of commoners, and forbid
the distribution of bootleg copies of the Scriptures in the common tongue
(one effective method in Spain was to burn bootleggers at the stake as public
entertainment).
Similarly, only members of the Darwin Party can rightly interpret the
transition from fish to tetrapod and other puzzles,
even when the data are missing or uncooperative, and only party members
are authorized to teach the nature of science to initiates.
Bootleggers are denounced as dangerous heretics, committed
to the flames of public diatribes. Design scientists are excommunicated
from the officially sanctioned journals; unable to publish, they perish.
Its instructive to read Gropps article with
these parallels in mind. The missing ingredient in his counter-reformation
manifesto is the very thing most people assume is the essence of science:
observed evidence. His whole argument hinges on politics, strategy, and
who has the authority to dictate what arguments students get to hear.
Since he picks on Phillip Johnson, maybe that is the parallel to Luther,
although like Luther, Johnson had many predecessors, some more qualified
and outspoken. And since Luther had some political allies who
gave him aid and comfort, the counter-reformation must have a political
arm to combat him. Gropp singles out Rick
Santorum as giving aid and comfort to the enemy; he says, Many
evolution activists believe that Sen. Santorums advocacy of ID and
various state and local ID initiatives across the country are proof
that citizens [read, political action committees] and scientists
must work together to defend the teaching
of evolution in the public schools. Thus, Grobb praises
efforts of the NCSE to form a coalition with political clout.
Here is where it is important to be familiar with Phillip
Johnsons theme, discussed at length in The Right Questions,
that the one who formulates the questions often wins the debate.
Evolutionary casuists are very good at stating the controversy in terms
where they cannot lose. They portray this as a contest between
science and pseudoscience (notice how the Party in Power gets to define
what pseudoscience is.) Its all about defending
the teaching of evolution (appealing to peoples Alamo emotions),
which are under attack by these religiously-motivated
radicals who dont understand science. All kinds
of emotional appeals are used to rally the activists to the crusade:
the enemy is well funded and well organized (you can cut
the hypocrisy with a knife), and we need a strategy to
counter this dangerous threat to science.
Buzzwords abound: creation must
always be appended with ism,
so that it sounds like a cult, while evolution is equated with science;
big lies abound, like the one that ID
wants to remove evolution
from the science classroom when, in fact, they want to teach more
about it (including the contrary evidence); red
herrings abound, such that the claim this issue is about
separation of church and state (with the presupposition that
I.D. theory is inherently religious, but Darwinism is not);
non-sequiturs abound,
such as associating the amount of evolution taught with the quality
of science teaching. In this smoke-filled
battleground,
activists on both sides often jump into the fray, oblivious to the
issue of whether anyone is asking the right questions.
Is there a Diogenes here? Few are the
evolutionists who show any desire to critically examine whether
Darwinian theory can stand up to
the observed facts of nature. Do living things show evidence
of design, or do they not? Is time and chance sufficient to
produce a human being, or is it not? Can our universe be explained
in naturalistic terms only, or is information required? Such questions
are foreign to their mindset. Instead, the approach is, there
must be a way to stuff this uncooperative data into naturalism, which
I already know in my heart is true. Similarly, the
anticreationist literature is silent about these questions.
They either pass it off as a done deal; Big Science already looked at
Luthers writings and condemned them as heretical end of story.
When asked if a particular thing appears designed, they look at
generalities, including evil and suffering in the world, and
scoff, Well, a Designer wouldnt have
done it that way. But that is a religious argument,
not a scientific one, as Cornelius Hunter deftly demonstrated in
his book Darwins God, and expounds further in
his new sequel
Darwins Proof (Brazos Press, 2003
highly recommended).
Just as the Catholic church
portrayed itself as the one and only universal apostolic vicar of
Christ, the Darwin Church portrays itself as the one and only universal
vicar of science. It is a religious war. Its about
holding onto power. If it were not, they would welcome debate on the
new ideas of intelligent design, and the challenges that new discoveries
about life are posing to the Darwinian explanation. Gropps
article would be an invitation to debate the evidence, not
Activists Organize to Combat heresy.
That a counter-reformation has begun may be a
good sign that the Church of Darwin can no longer merely assume its
domination over science. True, Darwinist Tetzels (science writers in
the news media) are still gleefully
strolling about, selling indulgences (just-so stories)
with reckless abandon, but the
priests in back rooms of the Vatican (NCSE) are anxiously plotting their next
moves, alarmed at the number of
common-tongue ID books and videos being distributed to the student peasants,
despite the best efforts of the Inquisition. (As surely as
Gutenbergs press lubricated the rapid dissemination of
information damaging to the Church, the Web does today.)
Fearing an uprising,
the Darwin Party seems bent on a strategy that will fail as surely as the
efforts to stop the Reformation. Only the Church is authorized to
interpret the Scriptures backfired when enough literate peasants
could read the source documents, and could see the contradictions for
themselves. Only the Darwin Party is authorized to interpret the observed facts
of nature will fail, when enough literate citizens are liberated
from the Darwin-only rule in the science classroom, and can see the
evidence for themselves all the evidence, not just the
preselected props for Darwinism (finch beaks, peppered moths), but the
Cambrian explosion, the complexity of the earliest life, the laws of
thermodynamics, information theory, design detection, the honorable
history of design science, and much more.
Creation-Evolution Headlines is your source for
the data in the common tongue (and some reports smuggled out of
the Jesuits strategy sessions). Read it and pass it on.
Note: This commentary is no more a criticism of science
than the Reformation was a criticism of the teachings of Jesus.
It is rather a criticism of the naturalistic philosophers who have
arrogated unto themselves the right to be the sole interpreters of
natural phenomena, the definers of terms, and the censors of the
curriculum. It should be obvious from three years of reporting
here that we love science and true scientists.
Similarly, this commentary is
not a criticism of individual Catholics, many of whom are sincere and
good people who accept what they are taught, including many involved
in Catholic charities who sacrificially care for the poor and needy.
The comparison is about ideas put forth by the leadership.
Not all union members are as liberal as their union bosses, for instance,
nor do all seniors agree with political positions of the AARP.
The official stated positions of Protestant Reformers and Catholics
are the basis for comparing Big Science with those who would reform it.
There are many individual scientists who do not tow the Darwin Party line.

Speciation Theory Goes Postmodern 08/19/2003
From external appearances, the paper on fruit flies by an international team in
the Proceedings
of the National Academy of Sciences (online preprints, 8/19/03)
looks like the usual bland, boring,
incomprehensible scientific paper. It has lots of jargon, charts,
and graphs, and a sleepy title, Allopatric genetic origins for
sympatric host-plant shifts and race formation in Rhagoletis.
Its just the last sentence that wakes you up.
The paper starts off by pointing out the rift in
speciation theory (see January
15 headline) between the orthodox allopatric speciationists and
the heretical sympatric speciationists. This team uses data from
apple maggots to propose a compromise: Here, we provide evidence for a
partial reconciliation of the sympatric and allopatric views by
showing that inversion polymorphism forming latitudinal clines within
R. pomonella and contributing to sympatric host race formation
may have had much earlier geographic roots. (Dont
fall asleep yet.)
After presenting abstruse and convoluted arguments
about which genes might have diverged when, and supporting it with
alternative phylogenetic trees fit to various genes found in three strains
of American and Mexican apple maggots, they come up with a proposal
that should make everybody happy, even though Questions remain
concerning why mtDNA haplotypes did not introgress with nuclear
alleles (perhaps gene flow is male-mediated) and the current taxonomic
status of Mexican flies. (Dont fall asleep yet.)
Then their last sentence says (you can wake up now),
Nevertheless, our results evoke a surprising PostModern
synthesis of processes and personalities, adding to a growing
literature implying that the origins of animal species can be
as dynamic and rich (reticulate) as those for plants.
(Emphasis added in all quotes.)
Thats dynamic and rich, all right. Scientists hate
postmodernists, because postmodernists deny that anybody (including
scientists) is right. Everybody has their own truth, that is
true for them, whether it be scientism, Hinduisim, animism, Christianity,
Judaism, Islam, or Raelianism. All are equally valid and equally
pointless. To a postmodernist, everyone is a victim of some
oppressed minority, and we must be tolerant of everyones point
of view, including evolutionists and creationists. Because
such thinking undermines the privileged place scientists like to
feel they have, and puts evolutionism into fantasyland along with
everyone else, most scientists hate postmodernism.
So evolutionists should choke at this papers
last line, even if it was meant as an overture for peace.
The warring parties (allopatric vs. sympatric speciationists) are
not going to like the terms of the peace treaty, which might be
stated: Dont feel bad, nobody is wrong, and nobody is right.
Each of you is right in his own way.
It doesnt really matter who is right,
as long as we all get along and be tolerant. Look, we can piece
together lines from both stories to produce an even better story.
So like the players in Alice in Wonderland, everybody wins, and
everyone gets a prize.
Even more telling is their admission that the story of animal
origins is no less dynamic and rich (reticulate) (read:
fluctuating and high in fat) as the evolutionary origin story of plants.
Reticulate, n.: 1.
resembling a net; esp.: having veins, fibers, or lines crossing;
2. of, relating to, or constituting evolutionary change dependent on
genetic recombination involving diverse interbreeding populations.
So both animals and plants no longer have an evolutionary tree, but a network
of crossing lines. What else is left? We have already seen how
bacteria and archaea are already complex and networked with HGT (see
Aug. 11 headline). So for every group of
organisms on earth, it appears tree is in the eye of the beholder:
I think that I shall never see
The data fit a Darwin tree;
Trees are made by God, not we,
But only fools see phylogeny.
(Sincere apologies to
Joyce Kilmer;
we like his poem much better.) So
good news; you dont have to read the rest of the boring paper.
They just took it all away in the last sentence. Just be tolerant and say,
Hey, whatever grooves you, man, like, its cool.

Update 08/18/03: Iraqi Wetlands Disaster.
EurekAlert
reports status of the environmental disaster wreaked by Saddam Hussein in Iraqs
vast wetlands (see May 1 headline), and efforts
to restore parts of it. The US is trying to help Arabs recover from the devastation.
The area looks like you let a child loose in a sand box with hand grenades,

churned that country upside down, and turned extensive marshes filled with rich

Complexity from Simplicity: A New Kind of Science? 08/18/2003
In this week’s issue,
Science News takes a
critical look at Stephen Wolfram, the alleged genius who wrote A New
Kind of Science. That book has generated quite a stir among
scientists, and has amassed a loyal fan club. Wolfram, author of the
popular software Mathematica, got a PhD from Caltech at age 20.
Though critics cannot dismiss him as a crackpot, many dislike his
self-promotional style, and others deny the validity of his claims that
I have discovered vastly more than I ever thought possible, and
in fact what I have now done touches almost every existing area of
science, and quite a bit besides.
His theory of self-organization, similar to fractal theory,
revolves around the properties of
cellular automata, which are simple programs that generate complex
output. A small rule in an algorithm can have unexpected effects
far exceeding what could have been predicted. Wolfram has
spun off a lot of exhilarating ideas about where this new approach
can lead, reports Science News. For example,
rather than needing Darwinian evolution to explain the complexity
of living creatures.
Passing fad, or the closest thing to Newton in 350 years?
We agree with Ray Kurzweil that “Wolfram seriously overstated the
complexity that simple programs produce. On the topic of living
organisms, for instance, Kurzweil asserts that unless factors beyond
simple rules are invoked, one can’t explain ‘insects or humans or
Chopin preludes.’”

Fossil Beetle Leaves Color Imprint 08/18/2003
National
Geographic reports on fossilized beetles in Germany that still have the iridescent colors of
their shells plainly visible after 50 million years. This beetle and others from
the same site, are very rare examples of fossils that retain any original color,
and are the oldest colored fossils ever found, the article states. The color
is not the result of pigment, but closely-spaced layers that intensify certain wavelengths
like a film of oil on water.
The incredible part of this story is not the beetle, but the scientists, who have no
stomach churning over the dating of these fossils. That such delicate, ephemeral
characteristics could survive without any modification for so long should cause one to
question the obvious. 50 million years is a long time; so long, in fact, that
the earth supposedly went through multiple upheavals, mountains were built, canyons
eroded, whales evolved from land animals, and most species underwent major changes,
according to the evolutionary story (even though these beetles look thoroughly modern.)
Humans were allegedly 45 million years or more in
the future when these beetles were supposedly buried.
We only know of about 7000 years of recorded history, history that
was observed by humans who kept records.
If 7000 years were a foot, 50 million years would be 1.3 miles. How can anyone
be so dogmatic about unobserved history? Why not question the dates?
The answer, of course, is that the theory of evolution depends on them.
Evolutionary geology and biology are locked in a deadly embrace that could well
drown them both together.

Notable Nuggets 08/15/2003
Short topics from the news warranting further reading:
-
Newton Not a Newtonian:
If by Newtonian we mean someone who pictured the universe in
mechanistic clockwork, then He (Newton) of all people
was no Newtonian. This from a review by Patricia Fara
of a new book Isaac Newton by James Glieck (Pantheon, 2003),
published in
Science
Aug 15.
Like most people, Newton was a complex person.
His Principia reads like impeccable logic; why, then, the
apparently arcane obsessions with alchemy, Solomons
temple, early Christian heresies and other diversions? Gleick
feels they fed directly into his cosmological theories. He probably
does not have the last word on Newton. From Newtons own pen,
however, it is clear he saw the universe as the grand masterwork of the
Biblical God.
Next headline on: Intelligent Design.
- Sweeping On to the Grand Fallacy:
It takes chutzpah to describe 3 billion years of prehistory lacking human
observers. Guy M. Narbonne respects Andrew H. Knolls charge into
the unknown in his review of the latters book Life on a
Young Planet (Princeton, 2003), in the
Aug. 15
issue of Science. Knolls confidence of
modern evolutionary biology having superseded Genesis is seen in his
whimsical naturalists Generations of Abraham: bacteria
begat protozoans, protozoans begat invertebrates, invertebrates begat
fishes, and the like.
To subscribe to this genealogy, one must face Darwins
Dilemma, the Cambrian explosion. Knoll, not afraid to wade
into the major controversies, nor ... afraid to use words like
maybe and perhaps where the evidence is not
yet conclusive, dives right in. His view: the
survival of diverse eukaryotic lineages imply that snowball
Earth had a discontinuous ice cover with numerous marine
refugia, such that this and other intervals of rapid
environmental change caused temporary breakdowns of the established
ecosystems with their harsh competition for resources and thereby
permitted the new experiments of life [sic] that ultimately led to
our modern world.
Since when are scientists congratulated
for their imaginative use of creative bluffing? There is no
evidence for any of the story, and no way to observe it, either.
You cant dismiss Darwins Dilemma by waving your arms and
saying catastrophes happened so fast, they didnt leave
any fossil evidence. What kind of weird-science philosophy makes
environmental stress the Good Witch of the Gaps? Good grief.
Next headline on: Darwinism (and next item, below).
Next dumb story (and next item, below).
- Squeezing Data Points Into the Theory:
Some Washington University biologists writing in
Science
Aug. 15, studied iguanas and found a surprise: four taxa exhibit
substantially different patterns of evolution. To normalize
the discrepancies, they postulate an inverse relationship between
timing of diversification and morphological disparity within subclades,
which may be a general feature that transcends the historically
contingent properties of different evolutionary radiations.
Translated, this means that all the change happens rapidly when species
split into different groups, then they remain relatively unchanged for
long periods.
Ad hoc speculation is rife within
evolutionary theory. No data can possibly falsify it.
Welcome to the tolerant, diverse, inclusive Darwin Party where all data
are welcome, as long as they agree to fit in.
- Fatty Acids, Fatty Theories:
To get fatty acid synthesis to fit into the evolutionary tree of
Mycobacterium tuberculosis, Irish biologists invoke
lateral gene transfer, adaptive evolution, and gene duplication.
Their paper in the
Proceedings
of the National Academy indicates they were surprised that
of the eight gene families examined, five of the phylogenies
reconstructed suggest that the actinobacteria have a closer relationship
with the alpha-proteobacteria than expected. This is either due
to an ancient transfer of genes or deep paralogy and subsequent
retention of the genes in unrelated lineages i.e., unrelated
bacteria came up with the same genes in parallel.
In conclusion,
they say, Fatty acid biosynthesis is likely a very ancient
pathway.... It might seem likely that in a similar way to translation
or replication, a mechanism of carrying out this function would have
been invented [sic] early in evolution and the contemporary operation
of this pathway would have remained largely unchanged.
But they find significant changes, anomalies, and bottlenecks; of one
key enzyme, they say it is most unusual to think that it was
invented [sic] late in evolution, so maybe there has been
significant turnover and replacement of genes with similar functions.
Of another gene, they visualize duplication followed by positive
selection, concluding, This is likely to be a kind of
tweaking of the mechanism of fatty acid synthesis, perhaps
for improved functioning after major alterations of the pathway.
We just want readers to see that hand-waving and pantheism is
alive and well in scientific journals. Registered members of
the Darwin Party get free passes to fantasyland.
