Darwinism is an exercise in creative bookkeeping for hiding that its explanatory debts far exceed its explanatory resources. Think of the No Free Lunch principle, therefore, as an auditors tool for scrutinizing Darwinisms inflated claims and showing its debts to be in default. Fortunately, as recent corporate debacles have taught us, creative bookkeeping can at best postpone but not avoid an official declaration of bankruptcy. | ||||||||||||||||

Do Guppies Make Good Darwinian Grandmothers? 12/31/2005
Since guppies are livebearers that provide no postnatal maternal care, Reznick et al. predicted the populations would show no differences in postreproductive lifespan--which is what they found.The article then stated that whether postreproductive lifespan can be under selection at all is an open question. But then, it said that this new study helps gain an evolutionary perspective on such matters including how they relate to humans. What kind of reasoning says, we predict there will be no evolutionary natural selection on a process, then uses the confirmation of the prediction as evidence for evolution? You cant have it both ways. The article stated an evolutionary principle: For natural selection to shape the twilight years, postreproductive females should contribute to the fitness of their offspring or relatives. Notice that word should. If natural selection is the be-all and end-all of existence, and if nothing makes sense except in the light of evolution, and if most biologists expected there to be a granny effect, then Reznicks study amounts to falsification. Grandparents everywhere should be relieved that another evolutionary principle has been falsified, because now their self-worth does not need to be tied to their tubes.A Foxhole Anthology: News from the CrEv Trenches 12/30/2005 ![]() If Judge Jones or the NCSE thought for a minute that the Dover ruling would bring an end to the ID wars, the news media should clear up any miscalculations. Here is a clearinghouse of recent headlines:
Bluffing words, commotion, posturing, strategizing, politicking, grandstanding... science, please? None of this matters, really; Darwinism has already been falsified (see next story). Since evolution has failed in a most spectacular way, we ought to be concerned not with war but with clean-up.Thermodynamics Defeats Evolution in a Most Spectacular Way 12/30/2005 ![]() The second law of thermodynamics (2TD), what Sir Arthur Eddington called the supreme law of nature, does not permit evolution, argued Granville Sewall in The American Spectator; in fact, evolution violates it in a most spectacular way. A mathematics professor at Texas A&M University, Sewall explained that 2TD applies to much more than heat flow; it applies to every real system. He defended the second law against the standard reply, the open system argument. Not anything can happen in an open system, he explained, not even with a Darwinian mechanism; otherwise, we would expect computers, spaceships, television sets and DNA to appear just with the energy of the sun. Sewalls lay-level article was prompted by the wars over intelligent design. He adapted it from the appendix of a book he co-authored on The Numerical Solution of Ordinary and Partial Differential Equations (see end of article for reference and link). The appendix, A second look at the second law, asked, Can ANYTHING happen in an open system? and is available online at Math.tamu.edu. The venue may have been a conservative rag, but the author knows what he is talking about. Dr. Sewall is a mathematician and author with expertise in probability and the second law of thermodynamics. He is right; tell a Darwinist about 2TD, and you will get little more than an open system brush-off. This article pulls that rug out. No more simplistic open-system answers, Darwin Party: fess up, you cannot get brains from matter in motion, open system or not. Do the math. Face the real world. Just-so storytelling cannot help in the world of hard physical science. Its the ultimate Reality Check. No federal judge can help you now. What would you have him do: declare the second law of thermodynamics unconstitutional? Rule it inadmissable because of separation of church and state? Go ahead and try. Your opponents will just appeal it to the court of last resort: the real world.Evolutionary Arms Race Is Coevolution Relentless? 12/29/2005 ![]() Camellias and the weevils that attack their seeds seem locked in conflict. The thicker a camellia grows its protective woody covering around its seeds, the longer the feeding tube on some weevil to break through and devour. John R. Thompson talked about such coevolutionary arms races in Current Biology1 and asked whether such wars can go on forever, leading to increased exaggeration of traits. The answer is, apparently, there are limits. Traits vary in a mosaic pattern across populations. Not all camellias are infested by beetles with the longest boring tools. As with any war, there are hotspots and coldspots. The dynamics of arms races seem to buffer both species against extremes. Collectively, these studies suggest that coevolution is a pervasive process that continually reshapes interspecific interactions across broad geographic areas. And that has important implications for our understanding of the role of coevolution in fields ranging from epidemiology to conservation biology. Many diseases, for example malaria, vary geographically both in parasite virulence and host resistance, potentially creating regions of coevolutionary hotspots and coldspots. The spread of introduced species seems be creating new geographic mosaics of coevolution as some species become invasive and coevolve with native species in different ways in different regions or drive rapid evolution in native species, sometimes in less than a hundred years or so. The results for Japanese camellia and camellia weevils reinforce the developing view that interactions coevolve as a geographic mosaic across landscapes, and it is often difficult for one partner to get ahead of the other (or others) everywhere. (Emphasis added.) 1John R. Thompson, Coevolution: The Geographic Mosaic of Coevolutionary Arms Races, Current Biology, Volume 15, Issue 24, 24 December 2005, pages R992-R994, doi:10.1016/j.cub.2005.11.046. This appears to provide more slippage on the evolutionary treadmill (see 03/17/2003 entry). Though the word evolution is involved, dont be confused; this has nothing to do with macroevolution, like bacteria evolving into people. Coevolution leads to exaggerated traits between two interacting species, like the beaks of hummingbirds and the flowers they pollinate. As with all other observed forms of microevolution, including Darwins famous finches, it involves the modification of existing traits not the origin of new ones.Echoes of Historic Supernovae Observed 12/29/2005 ![]() Astronomers using telescopes at the Cerro-Tololo observatory in Chile were able to detect the faint light echoes of supernovae (see EurekAlert, Space.com and original paper in Nature1). They found three light echoes for six of the smallest previously-catalogued supernova remnants (SNR) in the Large Magellanic Cloud (LMC), a small irregular galaxy visible from the southern hemisphere. Assuming the shock wave moves out less than 10,000 km/sec, and calibrating against the echoes from the known 18-year old remnant of SN1987A, they estimated the ages of two of them at 410 and 610 years. They believe surveys could uncover many more, now that they know what to look for. The light echoes provide a method for fixing the ages of supernova remnants. 1Armin Rest et al., Light echoes from ancient supernovae in the Large Magellanic Cloud, Nature 438, 1132-1134 (22 December 2005) | doi:10.1038/nature04365. Its interesting that there are no supernova remnants claimed to be tens or hundreds of thousands of years old or older. One of the most distended SNR's in our galaxy, the Veil Nebula, is believed to be only 5,000 years old (see 02/16/2001). Even so, all things being equal, the light from such an event would be expected to take some 160,000 years to arrive at earth. Why are there no older remnants reported? Is the same true for novae? Here is a good research project for someone who likes to catalog things and think about their implications.Astronomers See Poison Around Star, Think Life 12/29/2005 ![]() The Spitzer Space Telescope discovered acetylene and hydrogen cyanide, two deadly gases, around a star. Some astronomers got all excited and thought of the birth of life. The title of a press release from Jet Propulsion Laboratory read, Partial ingredients for DNA and protein found around star. The two carbon-containing substances were found in the dust disk of star IRS 46 in Ophiucus by the Spitzer infrared instrument. This was the only one of 100 similar stars that contained the signature of these molecules in its surrounding disk. The press release explained the significance: Here on Earth, the molecules are believed to have arrived billions of years ago, possibly via comets or comet dust that rained down from the sky. Acetylene and hydrogen cyanide link up together in the presence of water to form some of the chemical units of lifes most essential compounds, DNA and protein. These chemical units are several of the 20 amino acids that make up protein and one of the four chemical bases that make up DNA.The implication is that this star might be in the beginning stages of a chemical evolution process, assumed to be similar to what they believe led to life on earth. Another team member explained, This infant system might look a lot like ours did billions of years ago, before life arose on Earth. Evolutionists and astrobiologists like to call anyone who questions their views people of faith. You have just seen one of their stories use the words believed, thought to be, possibly and might. OK students, what are the observations? 100 stars with dust disks, and only one with two poisonous substances in their spectra. Another observation is that these substances, if mixed on earth in a test tube by intelligent chemists, who have provided an appropriate surface in the presence of water, at the right temperature and concentration, will form some amino acids and one purine that is part of one DNA base. Does the word life jump out of these observations? If not, where is your faith?Bombardier of the Sea 12/28/2005 ![]() Creationists have made much of the bombardier beetle (#1, #2) whose firing chambers would explode if the timing and mixture of ingredients did not work perfectly together. Now, here is a similar case in the lowly sea slug. EurekAlert described research by Georgia State University scientists, who found that the sea slug Aplysia mixes three inert ingredients to produce a sticky secretion, dyed purple, for defense: Aplysia packages these innocuous precursors separately and then releases them simultaneously into its mantle cavity at the precise time when they are needed, explained [Charles] Derby. This mechanism insures the secretions potency against attacking predators to enable sea slugs to escape. (Emphasis added in all quotes.)The secretion seems to contain a healing compound. The antimicrobial property probably evolved to work against predators, said Derby. But it might also function as an antimicrobial salve for Aplysias own wounds. The evolutionary mythoid contributes nothing of substance to this story. On grounds of intellectual honesty and scientific integrity, we need to call Darwinists on the carpet for simply claiming evolution blindly made irreducibly complex systems without telling us how. This is more of the BAD strategy (bluffing assertions of dogmatism) that lets Darwinians escape while secreting a sticky dyed goo that obscures understanding.Historic Scopes Trial Photos Uncovered 12/28/2005 ![]() Dozens of photos of the 1925 Scopes Trial, never before published, were uncovered in Smithsonian archives by independent historian Marcel C. LaFollette, reported Science News.1 One photo shows the famous scene of Clarence Darrow interrogating William Jennings Bryan on the witness stand; another shows a close up of John Scopes. LaFollette is writing a new book on the Scopes Trial based on the photographs. They were taken by Watson Davis, managing editor at the time of Science Service, the publisher of what is now Science News. The article by Ivars Peterson states that Science Service was a help to Darrow and was helped by the trial in fact, the trial launched it to prominence: The Scopes trial was important to Science Service financially. Newspapers paid for articles from the trial, and these funds helped support the struggling organization. 1Ivars Peterson, Archival Science: Rediscovered photos provide a look inside the 1925 Scopes evolution trial, Science News, Week of Dec. 24, 2005; Vol. 168, No. 26/27 , p. 408. Its important to know about the Scopes Trial because so much political hay was made out of it. The hay machine grinds on to this day. Maybe Science Service provided the eminent rhetorician Dudley Field Malone (see loaded words in the Baloney Detector), or the scholarly scientist Maynard Metcalf (see equivocation), or the logician Horatio Hockett Newman (see either-or fallacy). Maybe Watson Davis helped provide boilerplate for The New Republic (see fear-mongering). The reporting about evolution in Science News hasnt changed much. In this same issue, Bruce Bower, in an attempt at being funny, wrote a scathing satire against intelligent design, so biased and full of his own hot air it is not even remotely credible or amusing.Abortion Pill Can Kill 12/28/2005 ![]() An ugly secret has come out of the abortion drug mifepristone known as RU486. It can kill normal, healthy women, and its approval by the FDA involved procedural violations that overlooked known safety concerns at the time. Source: Annals of Pharmacotherapy news release (see also EurekAlert). The research paper by Margaret M. Gary, MD and Donna J. Harrison, MD1 examined 607 cases from the FDAs Adverse Event Reporting System (AERS): RESULTS: The most frequent AERs were hemorrhage (n = 237) and infection (66). Hemorrhages included 1 fatal, 42 life threatening, and 168 serious cases; 68 required transfusions. Infections included 7 cases of septic shock (3 fatal, 4 life threatening) and 43 cases requiring parenteral antibiotics. Surgical interventions were required in 513 cases (235 emergent, 278 nonemergent). Emergent cases included 17 ectopic pregnancies (11 ruptured). Second trimester viability was documented in 22 cases (9 lost to follow-up, 13 documented fetal outcome). Of the 13 documented cases, 9 were terminated without comment on fetal morphology, 1 was enrolled in fetal registry, and 3 fetuses were diagnosed with serious malformations, suggesting a malformation rate of 23%.The authors suggest these may be just the tip of the iceberg due to reluctance of institutions to report adverse effects. They concluded, AERs relied upon by the FDA to monitor mifepristones postmarketing safety are grossly deficient due to extremely poor quality. 1Margaret M Gary and Donna J Harrison, Analysis of Severe Adverse Events Related to the Use of Mifepristone as an Abortifacient, The Annals of Pharmacotherapy, Published Online, 27 December 2005, www.theannals.com, DOI 10.1345/aph.1G481. The power of advocacy to trump ethics and safety has been seen in this case and in the recent stem cell flap. How many anxious women have been reassured by abortion providers that RU486 is a safe and private way to end an unwanted pregnancy? Why have not these reports caused the FDA to pull this dangerous drug from the market? When desire runs science, watch out. That would never happen with a materialist wanting to remove God from science now, would it?Health from Unlikely Sources: Poison and Scum 12/27/2005 ![]() Everything in moderation, health professionals remind us during the holidays. Some things, however, none of us would have wanted at all till scientists found there was treasure in them. Botulinum toxin (botox), for instance, is one of the deadliest of biological poisons, but by now everyone knows it is being put to good use in cosmetic surgery. A news release on EurekAlert announced that botox is useful for more than just ironing wrinkles. In addition to treating excessive sweating or reducing skin wrinkles, it is also a highly effective natural substance that normalizes muscle activity and can be used to reduce pain and itch. Doctors keep finding new uses for botox at both ends of the digestive tract. Another article on EurekAlert announced a promising substance in pond scum that might lead to a treatment for Alzheimers disease. A substance in Nostoc, a cyanobacterium, shows potent activity as a cholinesterase inhibitor. If so, it might help slow the degradation of mental and memory functions in those suffering from the degenerative disease. Science should not only help us understand the natural world, but find ways to improve the human condition. Sir Francis Bacon echoed Jesus teaching that a tree is known by its fruit. A good science will produce good fruit: in the case of science, increased health and prosperity for humans in ways that improve the environment (compare with the fruit of Darwinism: see 11/30/2005). We should look at the world like a treasure hunt, the way George Washington Carver did. Things that seem dangerous, ugly or boring sometimes prove to contain hidden treasures.How Blind Cave Fish Lose Color 12/26/2005 ![]() A study on cave fish revealed that several populations can have mutations to the same gene. A gene that produces melanin, named Oca2, was found to be mutated in two separate populations of cave fish, resulting in albinism. This same gene can produce albinism in humans. The replicated experiment is a powerful tool for experimental science, but typically unavailable in the study of evolution. Cave adaptations have evolved in many species independently, however, and each cave species can be considered a replicate of the same evolutionary experiment that asks how species change in perpetual darkness. A frequent outcome is that the species lose pigmentation or become albino. Cavefish, therefore, are a rich source for the examination of the evolutionary process. (Emphasis added.)It was surprising to the multidisciplinary team why this gene, and not others that can also produce albinism, was implicated. One possibility, suggested by the researchers, is that it is a large gene presenting a big target for mutations, and it seems to have no other functions besides helping to make melanin, the press release on EurekAlert states. Therefore, it doesnt diminish other aspects of fitness when it is mutated. Here is a situation where evolutionary theory is compatible with intelligent design or creationism. Its not a case of evolution in the sense of new functional information being added; its a case of function being lost. How this loss of information affects an organism is interesting, and it is worthwhile question to ask why two cave fish populations would get the same mutation to the same gene. If one assumes that the fish began with fully-operational Oca2 genes (as in creation/design), then it follows that a reproducing population of fish with mutations in that gene will lead to a population of albinos, if the benefit of having color no longer matters in the cave environment. This is downward evolution, not upward evolution. The story differs from the just-so storytelling of Darwinian theory, because we have plenty of empirical evidence that mutations lead to loss of function, but no evidence that mutations can produce new function. Darwinists try to call this evolution (in the sense of change over time), but it doesnt do anything to help Charlies story that fish evolved from pre-fish, or ultimately, from one-celled organisms. Creationists could just as well study loss mutations to investigate the extent of genetic load (deterioration) over time since the original perfect creation; convergent devolution, therefore, is non-controversial, but convergent evolution is what lacks empirical support.How Apemen Learned to Give Christmas Presents 12/25/2005 ![]() For your Christmas amusement, some scientists think they have solved the evolution of gift giving. In an announcement on EurekAlert called Why we give: New study finds evidence of generosity among our early human ancestors, the introduction states, A groundbreaking new study examines the origins of holiday giving and finds that our early human ancestors were frequently altruistic. How could Michael Gurvin (UC Santa Barbara) figure this out, without human ancestors to observe or ask? For his paper in the upcoming Feb. 2006 edition of Current Anthropology, he studied food exchanges in two small-scale, non-market societies a classic context for understanding the evolution of conditional cooperation in humans. He found that altruism is costly without some kind of payback, but he also found that close kin and neighbors unable to produce much food sometimes receive more than they give. On the media front, the Science Channel has been airing a series called The Rise of Man during Christmas week. Producers seem to be getting more bold with skin. One episode showed tribes of completely nude Homo erectus humans in various stages of increasing enlightenment (these are played by actors, you know, with some creative facial makeup, but otherwise anatomically correct human bodies). Another showed a newly-evolved Homo sapiens tribe watching the effects of lightning in fear and awe. A delirious female falls to the ground in some kind of trance, jerking and babbling uncontrollably as the others look on with stupefied expressions. The narrator explains: and thus begins a new chapter in the rise of human consciousness: religion. Cavorting in the wilderness with incomprehensible grunts how did it come to this. (Were not talking about the actors in The Rise of Man; were describing figuratively the evolutionary anthropologists.)Evolution of the Christmas Tree: Firs Tie Oaks in Fitness Race 12/24/2005 ![]() In the struggle for existence, the conifers should have lost, because when angiosperms appeared, they had fancier valve jobs. Thats the feeling of a story introduced by Elizabeth Pennisi on Science Now. Those of us who celebrate Christmas tend to take fir and spruce trees for granted around the holiday season, she quipped, But without a special modification that allows these trees to efficiently transport water, we might be hanging our ornaments on a ficus instead, according to a new study. She explained: In order for photosynthesis to occur, tall trees must supply their uppermost leaves with water, which is pulled up from the roots by evaporation. Angiosperms such as oaks and willows accomplish this using a series of centimeters-long, tube-shaped cellular pipes. Tiny valves made of cellulose membranes connect each pipe and help keep air bubbles out. Christmas trees and other conifers have much shorter pipe cells, however, and therefore must use many more valves than angiosperms. This should create more resistance and make it harder for them to transport water. But they dont have any trouble at all, says John Sperry, a plant biologist at the University of Utah in Salt Lake City. (Emphasis added in all quotes.)Sperrys team measured water flow in 18 conifers, including bald cypress, junipers and redwoods, and compared results with 29 species of angiosperms. There was no essential difference. Conifers hoisted the water with equal ease, despite the shorter pipe cells. How do they do it? The reason, says [Jarmila] Pittermann, has to do with key differences in the valves. Angiosperm valves are simple membranes full of miniscule pores. In conifers, the valves consist of a circle of impermeable tissue surrounded by porous tissue. The conifers pores are 100 times larger than those in angiosperms and allow water to pass through relatively easily. This efficiency more than makes up for the additional valves on the way to the tree top, Pittermann says.The researchers said that this helps scientists understand water transport in wood. But the work also points to how conifers, which predate angiosperms and are often considered primitive, were able to survive once angiosperms populated Earth, Pennisi explains. Without these very special cells, one biologist claimed there wouldnt be any conifers anymore presumably because they could not compete against the angiosperms. The work was published in Science.1 In the paper, the authors did not explain how or when the unique structure of the conifer valve evolved. They just said that without the adaptation, angiosperms would have a 38-fold advantage in water transport: The superior hydraulics of the conifer pit are crucial for minimizing sapwood resistivity. If conifer tracheids had the pit resistance of angiosperms, their sapwood resistivity would increase by 38-fold.... This, added to the narrow diameter range of tracheids, would make it much more difficult for conifers to compete effectively with angiosperms. 1Pitterman et al., Torus-Margo Pits Help Conifers Compete with Angiosperms, Science, 23 December 2005: Vol. 310. no. 5756, p. 1924 | DOI: 10.1126/science.1120479. What did evolution have to do with this story, really? Did it contribute anything of value, even an ornament to hang on the tree? The results were not what evolutionists expected. Conifers ruled the Jurassic forests, then along come angiosperms with superior plumbing, and there should have been no contest. Those old, primitive conifers should have gone the way of the dinosaurs, and our Christmas trees would look very different. Sweep away the Darwinian mythology, and what remains? Two well-designed, highly successful groups of plants. They may have different ways of lifting water, but so what? From a design perspective, it would be just as productive a research program to find reasons for the difference. Clearly the conifers are doing well. The tallest trees in the world are conifers (see 04/22/2004). Conifers seem to do even better than angiosperms in many locations, such as at timberline, where they survive numbing cold storms and snow without even having to drop their needles. Nobody told them they were at a disadvantage against the new trees on the block.Dover Fallout Is Radio Active 12/23/2005 ![]() Reaction in the media from Judge Jones stinging decision against intelligent design (ID) in the Pennsylvania case Kitzmiller vs Dover Area School District has been rapid and varied. Evolutionists are overjoyed at this Christmas present the judge delivered, a dirty bomb they hope will put ID out of business, but the other side claims the damage is minimal and the debate goes on. Here are some samples:
Can we all remember that Judge Jones is just one man? His complete buy-in to the ACLU side, and complete rejection of all the pro-ID testimony, shows he is a sadly biased man at that. Isnt it just like liberal leftists to look to unelected judges to get their power. In no way does this decision reflect the amount of strong support ID is getting all over the country, and even other nations. If a vote were taken by most American parents of high school students, Charlie would be put out on a one-way ship to Christmas Island, along with his blood brother the Grinch.Mars Water Evidence Evaporates 12/23/2005 ![]() The strongest evidence for water from the Mars rovers has been called into question. Scientists from the University of Colorado at Boulder believe that the observations of sulfates and concretions are better explained by fumaroles in volcanic ash deposits (see also EurekAlert). Their paper in Nature1 explains that the model means high temperatures: Consequently, the model invokes an environment considerably less favourable for biological activity on Mars than previously proposed interpretations. Another paper in the same issue of Nature2 by scientists from University of Arizona and Los Alamos proposes rapid turbulent flows caused by meteor impacts produced the deposits, not periods of long-standing water as was previously assumed. The report by Robert Roy Britt on Space.com included a response from Steve Squyres, principal investigator for the Mars Exploration Rovers. He said he always contended that the water was primarily underground, but thought that alternative views are good for science. The rovers, by the way, both celebrated their One Martian Year Anniversary recently (about twice as long as an Earth year). Both rovers are still going strong (see JPL press release). Opportunity recovered from a shoulder injury not long ago. Engineers were able to get the robotic arm working again. The MER Website has posted some more special effects images in which the rovers are placed into the scene. This one of Opportunity on Burns Cliff would make a nice Christmas stocking stuffer. In other Mars news, the first results of the MARSIS instrument (Mars Advanced Radar for Subsurface and Ionospheric Sounding) on the European orbiter Mars Express were published in Science.3 The radar instrument can penetrate the surface for up to a kilometer. Researchers found an underground impact basin 250 kilometers in diameter, and probed the northern polar ice deposits in this first-ever survey of the 3rd dimension of Mars. 1McCollom and Hynek, A volcanic environment for bedrock diagenesis at Meridiani Planum on Mars, Nature 438, 1129-1131 (22 December 2005) | doi:10.1038/nature04390. 2Knauth, Burt and Wohletz, Impact origin of sediments at the Opportunity landing site on Mars, Nature 438, 1123-1128 (22 December 2005) | doi:10.1038/nature04383. 3Picardi et al., Radar Soundings of the Subsurface of Mars, Science, 23 December 2005: Vol. 310. no. 5756, pp. 1925 - 1928, DOI: 10.1126/science.1122165. Remember the optimistic claims that Opportunity had found evidence for long-lasting surface water? Remember how the astrobiologists immediately jumped to the conclusion that Mars probably had good conditions for life? (Theyre still doing it; see the 11/29 JPL press release). It was interesting to hear that the concretions or blueberries that seemed to clinch the argument for water have another explanation; they are apparently expected in an impact scenario, when a meteorite strike causes a short-term flood or base surge that can travel hundreds of kilometers from the impact site. It may be possible that the H2O on Mars is subsurface ice that might liquefy during an impact event, only to freeze or vaporize quickly afterward. Whatever they eventually decide, Mars doesnt have to be lively to be interesting.Stupid Evolution Quote of the Week 12/22/2005 ![]() Two Elizabeths Culotta and Pennisi get the award for evolutionary bravado for their piece in Science.1 They were trumpeting the magazines award of Breakthrough of the Year to Evolution in Action, a series of findings that ostensibly help us understand how evolution works. Whether the particular breakthroughs (the chimp genome, a study on chickadees that seems to support sympatric speciation, and studies of microbial resistance to antibiotics) actually supported belief in the common ancestry of all organisms (macroevolution), it didnt seem to quell their enthusiasm in the slightest: The big breakthrough, of course, was the one Charles Darwin made a century and a half ago. By recognizing how natural selection shapes the diversity of life, he transformed how biologists view the world. But like all pivotal discoveries, Darwins was a beginning. In the years since the 1859 publication of The Origin of Species, thousands of researchers have sketched lifes transitions and explored aspects of evolution Darwin never knew.They didnt seem to pay much attention to the fact that the geneticists and paleontologists were having a little difficulty in the same issue of the journal (see next entry). Nor did they pay any notice to the worldwide controversy over Charles Darwin and his theories. Editor-in-chief Donald Kennedy did notice, however, as he defended the award:2 Wait a minute, I hear you cry. Hasnt it been a trying year for evolution, considering the debates about teaching evolutionary theory in science classes in the United States and the headlines about Intelligent Design? On the contrary; in the research community, its been a great year for understanding how evolution works, through both experiment and theory. No single discovery makes the case by itself; after all, the challenge of understanding evolution makes multiple demands: How can we integrate genetics with patterns of inherited change? How do new species arise in nature? What can the new science of comparative genomics tell us about change over time? We have to put the pieces together, and it could not be a more important challenge: As the evolutionary geneticist Theodosius Dobzhansky once said, Nothing in biology makes sense except in the light of evolution.One might wonder, then, what scientists are seeing in the dark. Didnt Darwin himself promise light was coming 146 years ago to shed on most of these same questions? Kennedy pointed to his favorite example of the new light: a case of microevolution in stickleback fish. The findings, however meager, are not as important as the process, Kennedy explained: The exciting thing about evolution, he said, is not that our understanding is perfect or complete but that it is the foundation stone for the rest of biology. Other foundation can no man lay than that which has been laid, apparently. Maybe, though, even intelligent design has a role to play like the building inspector (see quote at top right of this page). Kennedy claimed, Genes that are now known to exert complex effects on body form at the macro level answer the commonly stated objection that complex structures could not have evolved from simpler precursors. And so it goes: Scientific challenges are raised, inviting answers. Hard to disagree with that, but who gets to judge the validity of the answers, if not the challengers? Other news outlets were quick to pick up on the Breakthrough of the Year story: MSNBC, San Diego Union-Tribune, the Independent and the BBC News, for instance. Readers are free to comb these articles for contenders for the SEQOTW award. 1Culotta and Pennisi, Breakthrough of the Year: Evolution in Action, Science, 23 December 2005: Vol. 310. no. 5756, pp. 1878 - 1879, DOI: 10.1126/science.310.5756.1878. 2Donald Kennedy, Editorial: Breakthrough of the Year, Science, 23 December 2005: Vol. 310. no. 5756, p. 1869, DOI: 10.1126/science.1123757. Pennisi ought to know better; she has reported on many an evolutionary crisis (e.g., 12/14/2004, 08/06/2004, 06/13/2003). To hear these two reporters cackling like spring chickens over a scrambled Darwin egg is pathetic. None of the breakthroughs listed bear any real support to the central claim of Darwin that all species descended from a single common ancestor in the dim, unrepeatable past. Kennedy acknowledged that scientific challenges have been raised by intelligent design proponents, and that they invite answers, but look who gets to judge the answers. Its like the kid getting to grade his own paper, or the defendant getting to play judge and jury, or the corporate boss getting to set his own salary and benefits. Its even worse than that. The Darwinists not only control the answers; they usually control the questions. They even control the language and the definitions of words. Small wonder that Charlie gets another medal.Cambrian Explosion Still Troubling to Evolutionists 12/22/2005 ![]() Despite Darwinian efforts to muffle it or spread it into a diffuse rumble, the Cambrian explosion (the near-sudden emergence of most animal body plans in the fossil record) was loud and snappy. A new phylogenetic study by Antonis Rokas (MIT), Dirk Krüger, and Sean B. Carroll (U of Wisconsin), published in Science this week,1 could not rid the models of rapid evolution across diverse clades, what they call radiations compressed in time. Their new broad study of gene sequences reached the same verdict as the fossil record. Their technical terms, translated into plain English, mean that the Cambrian explosion was real: The phylogenetic relationships among most metazoan phyla remain uncertain. We obtained large numbers of gene sequences from metazoans, including key understudied taxa. Despite the amount of data and breadth of taxa analyzed, relationships among most metazoan phyla remained unresolved. In contrast, the same genes robustly resolved phylogenetic relationships within a major clade of Fungi of approximately the same age as the Metazoa. The differences in resolution within the two kingdoms suggest that the early history of metazoans was a radiation compressed in time, a finding that is in agreement with paleontological inferences. Furthermore, simulation analyses as well as studies of other radiations in deep time indicate that, given adequate sequence data, the lack of resolution in phylogenetic trees is a signature of closely spaced series of cladogenetic events. (Emphasis added in all quotes.)Three other scientists commenting on the story in the same issue of Science2 tried to find ways around the study but were not too successful. Is the big bang in animal evolution real? they asked. Maybe it can be circumvented with more data, or with different analytical methods. In light of these concerns, are the conclusions of Rokas et al. justified? Should we ignore their study? Most certainly not, because they have produced a wealth of data and have shown that it might just be possible that the fossil record can be reconciled with molecular data. The resolution, however, was left in future tense (with emphasis on tense). Rokas et al. did not seem so optimistic. A press release from University of Wisconsin underscored Carrolls conclusion that the animal family tree is looking bushy in places. There were frenetic bursts of evolution he said. Despite their efforts to resolve the record, instead of a tree, we got a bush where many branches sprout close together. He said it was hard to distinguish evolutionary events, even with boatloads of data. Rokas found a way to put a positive spin on it. The difficulty we are facing in telling animal relationships apart is evolutions signature that some very interesting evolutionary stuff happened here, he chuckled. 1Antonis Rokas, Dirk Krüger, Sean B. Carroll, Animal Evolution and the Molecular Signature of Radiations Compressed in Time, Science, 23 December 2005: Vol. 310. no. 5756, pp. 1933 - 1938, DOI: 10.1126/science.1116759. 2Lars S. Jermiin, Leon Poladian, Michael A. Charleston, Evolution: Is the Big Bang in Animal Evolution Real?, Science, 23 December 2005: Vol. 310. no. 5756, pp. 1910 - 1911, DOI: 10.1126/science.1122440. Very interesting evolutionary stuff, indeed (but only to a demolition expert). The Darwin Party knows that critics hammer the point that the Cambrian explosion falsifies evolutionary theory. Oh, how the Darwinists would love to get around it! These two papers and the news article show that they cannot. Look at the bars on their timeline, representing the data: they stack nearly on top of one another. To the left are fictional, imaginary dashed lines connecting them into a phylogenetic tree, with absolutely no data, fossil or genetic, to support the inference. Should they be depriving students of these embarrassing findings? Most textbooks glibly state that evolution is a fact, and the fossil record proves it. This is a snow job if there ever was one. Demand accountability.How to Overcome Student Objections to Evolution 12/21/2005 ![]() Biology teachers face increasing difficulty from students coming into class with bad feelings about evolution (11/30/2005, 08/30/2005). Many pro-evolution teachers will be attracted to methods that have a demonstrable track record of relieving tensions and facilitating the process of getting students to accept Darwins theory. David Sloan Wilson (Binghamton U, NY) has just the thing. Writing in PLoS Biology,1 he introduced Evolution for Everyone, or EvoS for short, with the upbeat title, Evolution for Everyone: How to Increase Acceptance of, Interest in, and Knowledge about Evolution (compare 11/01/2005 entry about another suggested method) First, the bad news that made this initiative necessary: Evolution is famously controversial, despite being as well established as any scientific theory. Most people are familiar with the dismal statistics, showing how a large fraction of Americans at all educational levels do not accept the theory of evolution, how efforts to teach evolution often fail to have an impact, and how constant vigilance is required to keep evolution in the public school curriculum. Even worse, most people who do accept the theory of evolution dont relate it to matters of importance in their own lives. There appear to be two walls of resistance, one denying the theory altogether and the other denying its relevance to human affairs. (Emphasis added in all quotes.)Wilson impresses the reader right off the bat with statistics from tests of the EvoS method at Binghamton University, showing a pronounced shift toward acceptance of evolution among students, regardless of religious background, familiarity with the theory, or political persuasion. How did he do it? Wilson describes the multi-pronged approach as focusing on teaching a sequence of ideas and helping students catch the evolution bug. From the long article, a few highlights stand out. For one thing, EvoS does not shy away from controversy, but embraces it as a teaching opportunity. When students feel threatened by evolution, for instance, the teacher delves right in. Threatening ideas are like other threats, Wilson says; the first impulse is to run away or attack them. Make the same ideas alluring, and our first impulse is to embrace them and make them our own. OK, so while the teacher is trying to explain how evolution explains the world and helps provide ways to improve the future, a student objects that evolution has produced a lot of bad social policies. Now what? Dont dodge the question: This requires a discussion of past threatening associations, even before the theory is presented. Evolution has been associated with immorality, determinism, and social policies ranging from eugenics to genocide. It has been used to justify racism and sexism. All of these negative associations must be first acknowledged and then challenged. Its not as if the world was a nice place before Darwin and then became mean on the basis of his theory. Before Darwin, religious and other justifications were used to commit the same acts, as when the American colonists used the principle of divine right to dispossess Native Americans, and men claimed that women were designed by God and Nature for domestic servitude. These beliefs are patently self-serving and it should surprise no one that an authoritative scientific theory would be pressed into the same kind of service. It is the job of intellectuals to see through such arguments and not be taken in by them. Moreover, the deep philosophical issues associated with topics such as morality, determinism, and social equality are increasingly being approached from a modern evolutionary perspective and are among the topics to be discussed in the course. When these issues are discussed at the beginning of the course, students put their own threatening associations with evolution on hold and become curious to know how a subject that they associate with science (evolution) can shed light on a subject that they associate with the humanities (philosophy). Students who indicate exceptional interest are referred to books that are both authoritative and accessible, such as Daniel Dennetts Darwins Dangerous Idea.Wilson teaches evolution not as a choice between theology or materialism, but a third way: a process of change, in which the material organism becomes a kind of living clay that can be molded by environmental forces that influence survival and reproduction. This, he explains, enables evolutionary theory to make predictions about how organisms and populations adapt to their surroundings. Wilson encourages discussion groups. As another example of facing a controversial topic head-on, he divides students into groups to discuss infanticide: Choosing the subject of infanticide, I say that superficially it might seem that organisms would never evolve to kill their own offspring, but with a little thought the students might be able to identify situations in which infanticide is biologically adaptive for the parents. I ask them to form small groups by turning to their neighbors to discuss the subject for five minutes and to list their predictions on a piece of paper.Lest one think this is just talking about birds and bees, Wilson makes it clear that a key feature of EvoS is encouraging students to see human beings as integrally involved in the evolutionary process: One of the biggest tactical errors in teaching evolution is to avoid discussing humans or to restrict discussion to remote topics such as human origins. The question of how we arose from the apes is fascinating and important, but is only one of any number of questions that can be asked about humans from an evolutionary perspectiveincluding infanticide. If evolutionary theory can make sense of this subject for organisms as diverse as plants, insects, and mammals, what about us? If we operate by different rules than all other creatures for this and other subjects, why should this be so? The most common answer to this question is learning and culture, but what exactly are these things? Do they exist apart from evolution, or do they themselves need to be explained from an evolutionary perspective? I raise these issues early in the course, not to answer them, but to emphasize how much is on the table as part of the course.Wilson says that for millennia, people have considered humankind categorically different from other creatures in their mental, moral and aesthetic abilities. We are obviously unique in some respects, he acknowledges, but in exactly what way needs to be completely rethought. Students are encouraged to view human infanticide along the same lines as they did for animals, and to do the same for human warfare, learning, and culture all of which the teacher can demonstrate are present in varying degrees in the natural world. Such directness might seem worrisome to a biology teacher. Wilson reassures the reader that, in practice, the method actually produces compliant students: It might seem that boldly discussing subjects such as human infanticide (which the students quickly connect to the contemporary issue of abortion), along with other topics such as sex differences and homosexuality later in the course, is the ultimate in political incorrectness. However, I have taught this material for many years in prior courses without a single complaint, and the assessment of Evolution for Everyone demonstrates an overwhelmingly positive response across the religious and political spectrum. Clearly, there is a way to proceed that arouses intense interest without animosity or moral outrage. In the case of infanticide, evolutionary theory doesnt say that its rightit is used to make an informed guess about when it occurs. All of the students want to know if the guess proves to be correct for humans in addition to other creatures, regardless of their moral stance on abortion. Moreover, they see that the information can be useful for addressing the problem, whatever particular solution they have in mind. The importance of culture is not denied, but becomes part of the evolutionary framework rather than a vaguely articulated alternative. The picture that emerges makes sense of cases of infanticide that appear periodically in the news (typically young women with few resources and under the influence of a male partner who is not the father) and that previously seemed inexplicable. Nearly everyone values this kind of understanding and thinks that it can be put to positive use, as demonstrated by the quantitative assessment. More generally, including humans along with the rest of life vastly increases students interest in evolution and acceptance to the degree that it seems to lead to understanding and improvement of the human condition.Wilson continues; evolutionary changes are not always adaptive, nor are they always benign. Fitness is a relative and local concept, he explains. It doesnt matter how well an organism survives and reproduces, only that it does so better than other organisms in its vicinity. Overall, the teacher presents evolution as practical for explaining the observations without making any moral judgments. But then, what about morality? Thats part of our evolution, too, as more group discussion helps the students realize: If behaviors regarded as immoral in human terms are adaptive and natural, then arent all the fears about evolution justified? Nobecause behaviors that are regarded as moral in human terms are also adaptive and natural under the right circumstances, which can be illustrated with the following exercise of the sort suggested by Nelson and Alters. First, the class is asked to list the behaviors that they associate with morality. The most common items include altruism, honesty, love, charity, sacrifice, loyalty, bravery, and so on. Then they are asked to list behaviors that they associate with immorality, and respond with opposite items such as selfishness, deceit, hatred, miserliness, and cowardice. With these lists in mind, the students are asked three questions: (1) What would happen if you put a single moral individual and a single immoral individual together on a desert island? (The students quickly conclude that the moral individual would become shark food within days.) (2) What would happen if you put a group of moral individuals on one island and a group of immoral individuals on another island? (The students are equally quick to conclude that the moral group would work together to escape the island or turn it into a little utopia, while the immoral group would self-destruct.) (3) What would happen if you allow one immoral individual to paddle over to Virtue Island? (The answer to this question is complex because it is a messy combination of the straightforward answers to the first two questions.)The students learn, then, that situational ethics pop right out of evolutionary theory. This exercise is simple and entertaining, he says, but profound in its implications. It shows that most of the traits associated with human morality can be biologically adaptive. Students are assured that a quasi-traditional morality, including altruism and honesty (except for the occasional freeloader or non-cooperator) is a natural consequence of natural selection within groups. Alas, the teacher must admit that group selection can lead to a disturbing corollary. Cant behaviors that count as moral within groups be used for immoral purposes among groups? The answer to this question is yes, which means that moral conduct among groups is a different and more difficult evolutionary problem to solve than moral conduct within groups. By this time, students understand that scientists should one day be able to figure this out by such a useful, predictive theory as natural selection. The important point is that evolutionary theory can potentially explain the evolution of behaviors associated with morality and immorality. This is vastly different than the usual portrayal of evolution as a theory that explains immorality but leaves morality unaccounted for. The average student is well aware that immoral behaviors usually benefit the actor, that human groups have a disturbing tendency to confine moral conduct to their own members, and so on. When evolutionary theory is presented as a framework for understanding these patterns in all their complexity, including the good, the bad, the beautiful, and the ugly, it is perceived as a tool for understanding that can be used for positive ends, rather than as a threat.So you see, students, evolutionary theory should not be threatening. Its just a tool, a neutral way of looking at the natural world (including ourselves), so that we can explain a wide variety of observations that before Darwin seemed inexplicable. Its time to get into the heavy stuff: At this point (about mid-semester), the students are told that they have acquired a conceptual framework that can be used to study virtually any subject in biology and human affairs, which will be used to study particular topics for the rest of the semester. There is great flexibility in the topics that can be chosen, which is facilitated by having the students read, rather than a textbook, well-chosen articles from the primary scientific literature.(It can be safely assumed that Wilson does not have in mind sources like Of Pandas and People). The enlightened student is now ready to think about Darwinian medicine, and topics as diverse as violence, sexuality, personality, and culture to see what insights evolutionary thinking can provide. They realize that they have started to approach the study of humans in the way that evolutionary biologists approach the rest of life, with a common language that can be spoken across many domains of knowledge. They have arrived. One more thing: the student gets to choose his or her own topic and write it up in evolutionary terms. Suggestions: adoption, alcoholism, attractiveness, body piercing, depression, eating disorders, fashion, fear, hand dominance, homosexuality, marriage, play, sexual jealousy, sibling rivalry, social roles, suicide, video games, and yawning. As Dobzhansky famously remarked, nothing in biology makes sense except in the light of evolution. To summarize, Evolution for Everyone works by establishing a general conceptual framework through a sequence of ideas. The framework is then strengthened and consolidated by applying it to a number of specific topics. Virtually all students respond to the class because they cease to be threatened by evolutionary theory and begin to perceive it as a powerful way to understand and improve the world. Once the theory becomes alluring, the only remaining obstacle to learning is the intrinsic difficulty of the subject. That, it turns out, is not much of an obstacle either. Almost anyone can master the basic principles of evolution and incorporate them into their own thinking, providing both a foundation and an incentive to advance their knowledge in subsequent courses.Speaking of subsequent courses, Wilson is thinking way outside the box of high school or college biology. First, he encourages students who have caught the evolution bug to spread their newfound interests into a campus-wide program. The anthropology, psychology, economics and philosophy departments, with help from the administration, can all merge their evolutionary ideas into a cohesive picture, transcending traditional disciplinary boundaries. Special seminars can be held. Students can earn special EvoS certificates by completing required courses. Faculty advisors can counsel each student to develop a curriculum tailored to his or her interests from the menu of offerings. One last obstacle: other faculty. Though most of them already ridicule creationism, Wilson contends that most of them dont yet see the relevance of evolution to their disciplines. His plan, therefore, includes faculty training as well as student training, so that the university becomes a single intellectual community. In many ways, this type of experience approaches the ideal of a liberal arts education. It should be especially appealing to small colleges that have difficulty achieving a critical mass in single subject areas. Evolutionary theory is not the only common language, but it is a very good one that will eventually become part of the normal discourse for all subject areas relevant to human affairs and the natural world.Thats Evolution for Everyone one big, happy campus. 1David Sloan Wilson, Evolution for Everyone: How to Increase Acceptance of, Interest in, and Knowledge about Evolution, Public Library of Science, Biology, Volume 3 | Issue 12 | December 2005. In James Clavells chilling tale The Childrens Story, (a must read before continuing this commentary), the New Teacher comes to class after the conquest (presumably a communist takeover). She takes a frightened group of children and calms them into becoming compliant, trusting citizens. In just 23 minutes, she has gently and effectively dismantled their patriotism, their faith, their family loyalty and their most cherished beliefs before they even know what hit them. A well-trained, master manipulator, she is not a teacher: she is a facilitator, a guarantor of compliance with the new regime, an electrician who has cut off power from the resistance. She is just as much an arm of the State as the soldier on the battlefield, and perhaps even more effective. This is not education. It is indoctrination with finesse. |
