Charles Darwin presented On the Origin of Species to a disbelieving world in 1859three years after Clerk Maxwell had published On Faradays Lines of Force... Maxwells theory has by a process of absorption become part of quantum field theory, and so a part of the great canonical structure created by mathematical physics. By contrast, the final triumph of Darwinian theory, although vividly imagined by biologists, remains, along with world peace and Esperanto, on the eschatological horizon of contemporary thought. | |||||||||||||||||||

Leading Evolutionist Provides His Best Proof: HIV 05/30/2006
The aim of the talk, he explained, is to establish the testability and therefore prove the truth of evolution. After gaining the audiences sympathy with a few well-aimed gags at the creationists expense ...he waltzed them off at top speed on a whistle-stop tour of evidence for that evolution, this fundamental theory which he described as the grammar of biology.Eagerly anticipating the end of a long search for the elusive proof, the reader is presented with Jones greatest proof of evolution: ...the progression of the HIV epidemic. This example proves illustrative when it comes to the other great principle of evolution, natural selection: if you contract the HIV virus, Jones explained, your chance of remaining asymptomatic depends on your possession of a protective gene. Chimpanzees, in whom the virus first appeared, tend to have the protective variant; in Africa it is becoming more common; in Europe it remains rare. However, said Jones, if he were to make an evolutionary prediction, it is that in 1000 years time, every one of us will possess the protective gene, rendering the HIV virus no more harmful than flu.In his concluding remarks, he had nothing more to offer: He stuck with the example of HIV in his concluding examination of the ways in which we as humans are evolving now. While we have as a species evolved very little on a genetic level for many thousands of years, Jones said, there are other ways in which we have, quite clearly, evolved dramatically. Despite our extreme physical susceptibility to HIV, for example, we do, unlike chimps, have the power to contain the epidemic, via education and the development of drugs cultural and intellectual evolution, in other words. There are, he concluded, intelligent designers out there. But they work for the pharmaceutical industry.The reviewer ends with a lament that Jones uses a religious metaphor: The only problem, in the end, is that Jones was to use an inappropriately religious metaphor preaching to the converted this morning. One is left wishing that the 100m American creationists or the one in three people in the UK who allegedly believe that the universe was designed could be made to listen to him talk. Surely even they would find it difficult to resist him.In a related article in The Guardian, Jones said he has given up trying to confront creationists directly. (See 04/21/2006 bullet on Jones podcast, Why Creationism is Wrong and Evolution Is Right.) Thats it? Surely there must be something more concrete than this. Again, we have witnessed microevolution slipped in cleverly in place of some real evidence for macroevolutionNote: Reporting was suspended May 14-31 due to editor being on vacation.
A Challenge to our Victorian Ethics: Humans and Chimps Interbreeding 05/22/2006
David Page, a human geneticist at the Whitehead Institute in Cambridge, said the design of the new analysis was really beautiful, with all the pieces of the puzzle laid out. Whether the hybridization will turn out to be the right solution remains to be seen, but for the moment I cant think of a better explanation, he said. These crucial events in early human evolution are hard to judge dispassionately, Dr. Page noted. Wed like to have a more Victorian view of our genome, he said. This reminds us that we are really animals and gives us a glimpse of our past and a story that we might like to have told in a different way.The paper by Dr. David Reich of the Broad Institute concludes that humans and chimpanzees must have interbred during the early years after humans supposedly branched off from the chimpanzee family tree. He basis this on the fact that while the human and chimpanzee genetic codes found in their chromosomes all differ by a percentage, the most similarity on a percentage basis is found in the X chromosome, two of which are found in females, while the male has one X and one Y. Since evolutionists assume that the genetic code is changing at a steady rate over time, they attempt to date the time when one species splits off from another by the percent differences in their genetic code and the assumed rate of change. Dr. Reichs abstract reads: The genetic divergence time between two species varies substantially across the genome, conveying important information about the timing and process of speciation. Here we develop a framework for studying this variation and apply it to about 20 million base pairs of aligned sequence from humans, chimpanzees, gorillas and more distantly related primates. Human-chimpanzee genetic divergence varies from less than 84% to more than 147% of the average, a range of more than 4 million years. Our analysis also shows that human-chimpanzee speciation occurred less than 6.3 million years ago and probably more recently, conflicting with some interpretations of ancient fossils. Most strikingly, chromosome X shows an extremely young genetic divergence time, close to the genome minimum along nearly its entire length. These unexpected features would be explained if the human and chimpanzee lineages initially diverged, then later exchanged genes before separating permanently.Exchanging genes of course implies these early humans were mating with chimpanzees, a scenario that scientists found startling, according to a report in StarNewsOnline. Nevertheless, some are taking the theory seriously. However, not all are convinced. Daniel Lieberman, a professor of biological anthropology at Harvard, is quoted by the Associated Press in an article appearing in BBC News: Its a totally cool and extremely clever analysis. My problem is imagining what it would be like to have a bipedal hominid and a chimpanzee viewing each other as appropriate mates, not to put it too crudely. (If Dr. Lieberman were consistent in his evolutionary views, the concept of crudely would have no meaning.) Others are not so easily convinced. Science News reports that: Anthropologist Jeffrey H. Schwartz of the University of Pittsburgh sees no merit in the new findings. Reichs team looked for data to support an assumption of close genetic ties between humans and chimps but skimmed over evidence of human similarities to other primates, Schwartz asserts. The hybridization hypothesis pushes the limits of credulity, Schwartz says.For a creationist response, see David DeWitts article on Answers in Genesis. So what was really found in this study? Evidence of evolution, or was evolution just assumed?  The StarNewsOnline article reports:Bioneers Update: International Conference Held on Animal-Inspired Design 05/13/2006A principal finding is that the X chromosomes of humans and chimps appear to have diverged about 1.2 million years more recently than the other chromosomes... One explanation for this finding, Reichs team says, is that there was a hybridization between the recently separated chimp and human lineages.The principal finding of the study was not that the X chromosomes appear to have diverged over 1.2 million years more recently than other chromosomes. This just assumes evolution and takes off from there. The principal finding was that there is less percentage difference between the human and chimp X chromosomes than between other chromosomes. That this happened because humans and chimps were hybridizing is an explanation for the difference, not a finding, and is based on the assumption of Evolution and Long Ages. Hybridization is just speculation, however, it gets good headlines. When you have no evidence, speculation is all you have, and there is no shortage of it. Dr. Reich is quoted in the StarNewsOnline report:...chimpanzee ancestors, well-adapted for living off fruit in tropical forests, seem to have been adept at spinning off variations, such as gorillas, who live on vegetation, and the human lineage, which exploited the drier woodlands that opened up between the forests... Reich said.So now we not only know a bit about early mans sex life, but also what they ate and where they lived. And all this from variations in gene frequencies. What will they come up with next? Would you believe sexism? Notice this astonishing claim from PoliticalGateway.com: Geneticists have also found that women are biologically closer to chimpanzees than men are. That is because the Y chromosome, which only men carry, has changed more than the X chromosome. ![]() Georgia Tech came out with a press release about progress at their Center for Biologically Inspired Design (CBID) that opened last year (see 10/29/2005). At a two-day conference May 11-12, international representatives from 20 institutions shared their inspirations on how nature can help them solve some of the most complex problems of the day, just as it has inspired poets, artists and musicians. Though evolution by natural selection is often assumed as the mechanism by which animals solved their design problems, the main thing evolving at CBID is the belief that every animal must solve a particular problem to survive, so every animal embodies a design solution for a particular problem. The assumption that scientists are mining millions of years of knowledge embedded in the DNA of each creature does not appear to be essential for the scientists own work, which is really reverse engineering the design that is observed in current-day living creatures. While scientists, like Leonardo DaVinci, looked to nature for inspiration centuries ago, biomimetics has recently caught on as a hot area of research at universities across the country. Last year, Georgia Tech launched the Center for Biologically Inspired Design (CBID) as a way to encourage more of the interdisciplinary research that was already taking place among research groups. Now, the center boasts 20 members comprised of researchers from various fields of engineering, biology, chemistry, psychology, applied physiology and architecture.The press release mentions that UC Berkeley, U of Illinois, Caltech, and Case Western will be sharing results of their research. In addition, international scientists from U of Toronto (Canada), Max Planck Institute (Germany) and Shandong University (China) are sharing their work in progress. Here are examples coming out of this new kind of research:
Q: How did the Animal Plan It? A: Not by watching the DIY (Do-It-Yourself) Channel, but through the Discovery Channel of its own built-in Design Network.Dinosaur Boneyard: Dying Together Implies Living Together, Not Much Else 05/13/2006 ![]() (Guest article) CNN reported in an article from Associated Press that scientists have uncovered a small cache of dinosaur bones that contains bones from no other animals, and in their excitement have concluded that this means they must have hunted in packs. One expert called the discovery the first substantial evidence of group living by large meat-eaters other than tyrannosaurs like T. rex. The creature, which apparently measured more than 40 feet long, is called Mapusaurus roseae. The discovery of Mapusaurus included bones from at least seven to nine of the beasts, suggesting the previously unknown animal may have lived and hunted in groups. That hunting strategy might have allowed it to attack even bigger beasts, huge plant-eating dinosaurs... Coria noted the dig showed evidence of social behavior in Mapusaurus. The excavation found hundreds of bones from several Mapusaurus individuals but none from any other creature. That suggests the animals were together before they died, Coria said. Perhaps they hunted in packs, though there is no direct evidence for that, he said in an e-mail. Currie, in a statement from his university, speculated that pack hunting may have allowed Mapusaurus to prey on the biggest known dinosaur, Argentinosaurus, a 125-foot-long plant-eater. Holtz called the finding the first substantive evidence of group living by giant two-legged carnivores other than tyrannosaurs. Its not clear whether the animals cooperated in hunting, as wolves or lions do, or simply mobbed their prey or just gathered around after one of them made a kill, he said.Dinosaur bones are often found in large jumbled collections of many different animals and species, just as one would expect if they were buried in a catastrophic flood. This collection of bones is no different in that respect: it is a jumble of bones from seven to nine beasts, indicating that they are fairly disordered, since not even the total number of animals is certain. The only difference between this find and others is that there were no other animal bones mixed in, and yet this is called substantial evidence of group living. Some scientists feel a need to answer questions that are beyond the ability of piles of bones to answer, such as the behavior of these animals. This leads to unjustified speculations such as those found here. Notice the large amount of qualifiers in the above excerpt: might have, suggests, speculated. Such just-so stories add an air of respectability to the Big Story: Evolution, but the only real facts we have here are that a jumble of bones was found, all of the same species, all in one place, and with no other species mixed in. If you took off Old Earth glasses and put on Young Earth glasses, you would see just what one would expect the Genesis Flood to produce.Cactus Evolution Explained 05/12/2006 ![]() Phew, finally: now we know how cacti evolved, reports EurekAlert. Ouch! On second thought, hows that again? Two Yale scientists set out to figure out how the succulent plants turned leaves into spines. Using molecular methods, they identified the earliest cactus, but then said it already showed water use patterns that are similar to the leafless, stem-succulent cacti. [Our] analyses suggest that several key elements of cactus ecological function were established prior to the evolution of the cactus life form, explain the authors. Such a sequence may be common in evolution, but it has rarely been documented as few studies have incorporated physiological, ecological, anatomical, and phylogenetic data.But if the key innovations for cactus ecological function were already present, how is this an example of evolution? The press release is shamefully titled, How did cactuses evolve? It should be titled, Did cacti evolve? Apparently not; they were already adapted for their water use lifestyle from the start. If this sequence is common in evolution, where the function already exists before the evolution begins, it sounds like creation, not evolution.Paper View: Cosmic Questions, Personal Implications 05/11/2006 ![]() A good question provokes good thinking. It stimulates the imagination and inspires reasoning about profound issues. It focuses attention on problems, calls for clarification of assumptions, and leads to good follow-up questions, too. Such a good question was asked in four simple words by Sean M. Carroll1 (U of Chicago, Enrico Fermi Institute) this month in Nature.2 As part of a special issue focused on cosmology, Carroll asked, Is our universe natural? It should become immediately apparent that this question invites discussion of what we mean by natural, and touches on issues of universal scope even reaching beyond the universe, to put the cosmos in context. As we will see, the question also requires clarification of the nature, goals and limits of science. Dont be deceived by the simplicity of his first sentence; the avenues he explores to answer the question are indeed profound. It goes without saying that we are stuck with the Universe we have. Nevertheless, we would like to go beyond simply describing our observed Universe, and try to understand why it is that way rather than some other way. When considering both the state in which we find our current Universe, and the laws of physics it obeys, we discover features that seem remarkably unnatural to us. Physicists and cosmologists have been exploring increasingly ambitious ideas in an attempt to explain how surprising aspects of our Universe can arise from simple dynamical principles.He gets right to the definition of natural What makes a situation natural? Ever since Newton, we have divided the description of physical systems into two parts: the configuration of the system, characterizing its particular state at some specific time, and the dynamical laws governing its evolution. For either part of this description, we have an intuitive notion that certain possibilities are more robust than others. When we come across a situation that seems unnatural or finely tuned, physicists seize upon it as a clue pointing towards some underlying mechanism that made it that way. Such clues can occasionally be misleading, but they often serve to guide our thinking about how we can extend our understanding into unknown domains.This introduction makes it clear that Carroll views science as an attempt to get a handhold on observables, to reduce complex data to basic principles to rationalize reality in terms accessible to the human mind, reducible to laws and equations. Implicit in this paragraph is a dislike for contingency or appeals beyond the natural (whatever that means). But what if reductionist approaches fail? What if some things in nature really are beyond the capabilities of natural explanations? How far can a committed naturalist go in exploring increasingly ambitious ideas before admitting defeat? Arthur C. Clarke once said, The only way to discover the limits of the possible is to go beyond them into the impossible. This can be healthy, like T. S. Eliot said; never cease from your explorations, and when you come back to where you started, you will understand the place for the first time. As we shall see, though, if naturalism goes too far afield, and never comes back, it morphs into its own nemesis: supernaturalism. The introduction also hints that the naturalistic approach is built on faith. Scientists believe that even in the most puzzling phenomena there exist underlying physical or natural principles accessible to the human mind. Like the clues that lead a detective to solve a crime, puzzles spur scientists to discover underlying regularities, and to organize the observations into a unified, plausible account. Like Carroll said, scientists are not content to merely describe and catalog data; they want to be able to prove that, given certain initial conditions and natural laws, the phenomenon under investigation will follow. Carroll surveys several instances in the history of science where this approach has succeeded handsomely. It takes faith, however, to believe this approach can be extrapolated without bounds. If any system should be natural, its the Universe, Carroll states as a truism. Nevertheless, according to the criteria just described, the Universe that we observe seems remarkably unnatural. Example: the entropy of the cosmos is remarkably low, compared to what it could be (everything could be in black holes, or uniformly distributed, for instance). This implies that, for some reason, the early Universe was in a state of incredibly low entropy. In addition, our fundamental theories of physics involve huge hierarchies between the energy scales of gravitation, particle physics, and the recently discovered vacuum energy. These hierarchies appear finely tuned: so much so, that he compares it to a ball perched on top of a hill. Of course, it may simply be that the Universe is what it is, and these are brute facts that we have to live with, he concedes. More optimistically, however (and here is where faith comes in), these apparently delicately tuned features of our Universe may be clues that can guide us towards a deeper understanding of the laws of nature. There must be a point where the clues become expressible in equations, though, else this deeper understanding becomes gnosticism a form of intuitive wisdom for the elite, or a mystery religion. Will Carroll succeed in bringing heaven down to earth? A natural explanation should be testable to be considered scientific. Yet Carroll tells us that cosmologists have been increasingly open to radical ideas that seem untestable, even in principle. If so, the only law discovered may be one of Murphys every solution breeds new problems. Given this situation, physicists have been exploring dramatic extensions of our known theories, in an attempt to provide a larger context in which our apparently unnatural Universe is seen to make perfect sense. Interestingly, attempts to account for both the low entropy of the early Universe and the disparate energy scales of fundamental physics lead us to a similar idea: that the local Universe we observe is part of a much larger ensemble. This casts new light on the problems of naturalness, while raising vexing issues of its own; considerable advances in both theory and experiment will be necessary before we can decide whether we are learning the appropriate lessons from the clues provided by nature.Attempts to explain the fine-tuning of the universe through natural causes are not new. Inflation theory, for example, got rid of the flatness problem and horizon problem by positing an exponential expansion in the first second of the universe. Or did it? In a surprise revelation, Carroll shows that the solution was worse than the problem: It is worth emphasizing that the only role of inflation is to explain the initial conditions of the observable Universe. And at this it does quite a good job: inflation predicts that the Universe should be spatially flat, and should have a scale-free spectrum of adiabatic density perturbations, both of which have been verified to respectable precision by observations of the cosmic microwave background. But we are perfectly free to imagine that these features are simply part of the initial conditionsindeed, both spatial flatness and scale-free perturbations were investigated long before inflation. The only reason to invoke inflation is to provide a reason why such an initial condition would be natural.Contrary to popular accounts, therefore, inflation didnt solve the fine-tuning problem at all. Nor has it been solved since by more exotic forms of inflationary theory, such as chaotic inflation, spontaneous inflation or eternal inflation because these also rely on unobservable parts of the universe. Needless to say, proposals of this type are extremely speculative, and may well be completely wrong, he says; regardless of the model proposed, it is crucial to understand whether inflation plays a role in explaining how our observed configuration could be truly natural. Carroll then investigates whether the laws of physics are natural. It would seem the constants of physics could take any arbitrary values, though the laws and equations be tightly constrained. Could the particular values of these constants reflect mere environmental conditions, like the apparently arbitrary number of planets in our solar system? As mentioned in the introduction, that is not what we observe, he reminds us. The values are separated by huge hierarchies. Whats more, In contemplating the nature of these hierarchies, a complicating factor arises: we could not exist without them. We are back to the anthropic principle (08/16/2005), and the only way out, to make the universe a natural consequence of physics, is to propose an ensemble of universes a multiverse (12/18/2005): In the first case [i.e., we were lucky], there are two separate possibilities: either we are really lucky, in the sense that the observed hierarchies are truly unnatural and have no deeper explanation, or there exist unknown dynamical mechanisms that make these hierarchies perfectly natural. The latter possibility [environmental selection] is obviously more attractive, although it is hard to tell whether such dynamical explanation will eventually be forthcoming. Environmental selection, sometimes discussed in terms of the anthropic principle, has received renewed attention since the discovery of the dark energy. The basic idea is undeniably true [sic]: if our observable Universe is only a tiny patch of a much larger multiverse with a wide variety of local environments, there is a selection effect due to the fact that life can only arise in those regions that are hospitable to the existence of life. Of course, to give this tautology any explanatory relevance, it is necessary to imagine that such a multiverse exists.Carrolls brief digression into the properties of a multiverse, one that might yield our universe with its finely-tuned cosmological constant, ends in despair: At present, then, there is no reliable environmental explanation for the observed value of the cosmological constant. Moreover, other attempts to use anthropic reasoning seem to lead to predictions that are in wild disagreement with observations. But that does not mean the multiverse proposal has been falsified, he says, whether or not it is falsifiable. Yet if we cannot observe something or test it, and if we cannot falsify it if it is an appeal to a mystery world that someone finds attractive then have we not abandoned the goals of science? More importantly, limitations in our current ability to calculate expectation values in the multiverse are not evidence that there is no truth to the idea itself. If we eventually decide that environmental selection plays no important role in explaining the observed parameters of nature, it will be because we come to believe that the parameters we measure locally are also characteristic of regions beyond our horizon, not because the very concept of the multiverse is aesthetically unacceptable or somehow a betrayal of the Enlightenment project of understanding nature through reason and evidence.But then, how could one know that the observed parameters hold true for regions beyond our horizon, or whether those regions even exist? How does this differ from appeals to angels and demons or any other unseen entity as a proxy for observable effects? The ideas discussed here involve the invocation of multiple inaccessible domains within an ultra-large-scale multiverse, Carroll admits. For good reason, the reliance on the properties of unobservable regions and the difficulty in falsifying such ideas make scientists reluctant to grant them an explanatory role. He also admits that extrapolating our parameters into unseen realms is just as untestable. Maybe the multiverse concept will be testable some day; for now, it is not. We are back to definitions. What is natural? Is our universe natural? Is our cosmology natural? Can science even claim that a natural explanation is better than an unnatural one? It all seems in the eye of the beholder: Naturalness is an ambiguous guide in the quest to understand our Universe better. The observation that a situation seems unnatural within a certain theoretical context does not carry anything like the force of an actual contradiction between theory and experiment. And despite our best efforts, naturalness is something that is hard to quantify objectively.Carroll ends with appeals to the future, in effect saying that we are a long way from coming back to where we started and understanding it for the first time. The ultimate goal is undoubtedly ambitious: to construct a theory that has definite consequences for the structure of the multiverse, such that this structure provides an explanation for how the observed features of our local domain can arise naturally, and that the same theory makes predictions that can be directly tested through laboratory experiments and astrophysical observations. To claim success in this programme, we will need to extend our theoretical understanding of cosmology and quantum gravity considerably, both to make testable predictions and to verify that some sort of multiverse picture really is a necessary consequence of these ideas. Only further investigation will allow us to tell whether such a programme represents laudable aspiration or misguided hubris. 1Not to be confused with Sean B. Carroll (molecular biologist at U of Wisconsin-Madison) and several other scientists named Sean Carroll. 2Sean M. Carroll, Is our universe natural?, Nature 440, 1132-1136 (27 April 2006) | doi:10.1038/nature04804. This article is filled with fodder for philosophers of science, historians of science, and theologians. Modern cosmology has followed the Enlightenment dream, only to end up in the middle of nowhere, bankrupt. The attempt to naturalize everything has pushed them out of scientific bounds; they have no equations, no predictions, no falsification criteria, no confirming data, and no reason to continue the quest other than that they find natural explanations more attractive. This basically admits that naturalism, as opposed to theism, is only a preference. Carroll cannot even explain what natural means; he debunks the word as ambiguous and unquantifiable in one paragraph, only to hope, a few sentences later, that science will some day find a natural explanation. Substitute a nonsense word for natural in those sentences, to see that this makes scientific naturalism a meaningless and futile quest.See Comet Crumble 05/10/2006 ![]() A comet is breaking up before our eyes. Comet Schwassmann-Wachmann 3 has split into dozens of pieces and is crumbling quickly, like pieces of dried meringue. Science News tells about the breakup, and it made Astronomy Picture of the Day. The Hubble and Spitzer space telescopes are also documenting the event. This is not the first crumbling comet seen, nor the first breakup of this particular one; but it illustrates that comets are transitory features of the solar system. Based on information from the Stardust (03/14/2006) and Deep Impact (09/07/2005) missions, we know that at least some comets perhaps most have very low density and are easily disrupted. On May 11, Astronomy Picture of the Day posted a stunning photo of a conjunction of a comet fragment, a spiral galaxy, and the Ring Nebula. Like Humpty Dumpty, a comet is more easily broken than put together as it makes its great fall toward the sun. This destructive process cannot be maintained for long. See Mark Looys AiG article on why this provides evidence that the solar system cannot be nearly as old as believed. Claims of long age must invoke ad hoc scenarios involving unobserved sources of new material to replenish what we see disappearing before our eyes.Escape to Reality: Turn Off the Video Games 05/10/2006 ![]() Visitation at national parks has declined significantly, reports University of Illinois at Chicago, correlated with rising use of video games and home entertainment. My concern is that young people are simply not going outdoors or to natural areas, said a biology professor at the school, but are instead playing video games, going on the Internet or watching movies. Kids need vigorous physical activity and fresh air, the wholesome food of healthy living, instead of the processed junk food of artificial reality. We all do. Get outdoors and see the real world; escape to reality. Let the Creation Safaris Photo Gallery inspire you. Then turn off the computer and go take a hike.Mt. St. Helens Performs Fast Rock 05/10/2006 ![]() Before reading the caption, look at the picture of this football-field size mountain of rock at Astronomy Picture of the Day and guess how old it is. The answer: about five months. The smooth rock slab with its cornice tip has grown as much as a meter a day. The caption contains links to more information about the phenomenon. Someone should date that rock with radiometric methods and find out how many millions of years old it is. Since there are no fossils in it, it must be Precambrian.Book: Darwin Centurions Join Forces Against ID Visigoths 05/09/2006 ![]() A new book attacking intelligent design has chapters by most of the big names in evolutionary thought: Daniel Dennett, Richard Dawkins, Jerry Coyne, and others. An introduction to the book Intelligent Thought: Science vs. the Intelligent Design Movement (ed. John Brockman, Vintage Press, May 2006), with a synopsis of each chapter, is available at The Edge. The upshot is: materialistic Darwinism is the only scientific approach to origins, and the bizarre claims of fundamentalists with beliefs consistent with those of the Middle Ages must be opposed. The Visigoths are at the gates of science, chanting that schools must teach the controversy, when in actuality there is no debate, no controversy. You get the flavor of this book. OK, time for Battle of the Blurbs. If they can summarize the points of each essay in a sentence or two, we can summarize some quick responses. With apologies to Illustra, well call this Unmasking the Blustery of Lie.Fitness Costs What? Say That Again? 05/09/2006 ![]() Good news: evolution has figured out how to make your wounds heal faster. Bad news: the required mutation makes you go deaf. Believe it or not, that is the story told on News@Nature. Deafness gene has health benefit, wrote Alison Abbott. Protein from genetic mutation helps wounds to heal. The article treats this as a good thing, the way evolution works: A high frequency of mutation in any gene implies that there may be an evolutionary benefit for carriers. It is well known that various genetic mutations that cause sickness in particular geographical areas sometimes also protect against local diseases, so there is a trade-off, says [David] Kelsell.The article compared this with another oft-cited beneficial mutation another good-news, bad-news joke, that if you get the mutation for sickle-cell anemia, you become more resistant to malaria. Pick your poison. Kelsell says its speculation, but maybe the Cx26 deafness mutations have been selected owing to their beneficial effects on wounds. But then, how could the deaf winners tell each other the good news? Darwinists, come back when you can figure out how to get the benefits without the trade-offs. Your price is too high. Well take the slower healing and keep the ears.Q: Who Fights With Supercharged Harpoons? A: Jellyfish 05/08/2006 ![]() Weak, transparent, limp, and drifting in the water who would have thought these creatures possess one of the most powerful weapons in the animal kingdom? Jellyfish and hydras have stinging cells called nematocysts that fire so fast, no one has been able to catch the action of their microscopic harpoons till now. EurekAlert summarized a study being reported in Current Biology1 by a team that photographed them at 1,430,000 frames per second. They calculated the cells discharge in 700 nanoseconds (less than a millionth of a second). The explosive charge is accelerated to 5,410,000 G's in that brief flicker of time. Even though the weapon weighs a mere billionth of a gram, enough pressure is created in the discharge (15 giga-pascals, the pressure range of some bullets) giving it enough oomph to penetrate even a tough crustacean shell. Cnidarians use these weapons for prey capture and defense. The researchers propose that the high speed of discharge is caused by the release of energy stored in the stretched configuration of the collagen-polymer of the nematocyst capsule wall, the review explains. This ingenious solution allows the cellular process of vesicle exocytosis to release kinetic energy in the nanosecond range by a powerful molecular spring mechanism. 1Nuchter et al., Nanosecond-scale kinetics of nematocyst discharge, Current Biology, Volume 16, Issue 9, 9 May 2006, Pages R316-R318, doi:10.1016/j.cub.2006.03.089. When God gives an animal a technology, he doesnt do it halfway. (Evolutionists would have us believe jellyfish figured this out on their own, but this particular article mentioned nothing about evolution.) Another amazing fact is that some sea slugs called nudibranchs are able to ingest these nematocysts without setting them off, and line their backs with the borrowed technology. Figure that one out by slow, gradual, evolutionary processes.The Porridge Before the Soup: Too Hot? 05/08/2006 ![]() In the evolutionary theory of everything, there is a soup before the primordial soup we normally think of. Its the solar nebula, the whirling disk of dust, gas and ice that preceded the planets. Scientists used to think the nebula was differentiated like chemicals in a giant centrifuge, with the rocks close to the sun and the ices out near the perimeter. The situation was apparently not so simple; now, it appears someone stirred the porridge. Cometary material and interplanetary dust particles (IDPs) once thought pristine show signs of mixing and heating. This revision is discussed by Bernard Marty (geochemist, France) in Science.1 He discusses how fractionation ratios of oxygen and nitrogen vary dramatically across the solar system. The models are having to adjust to the new findings. No longer a slowly cooling and condensing nebula, the picture needs a solar flare here or there, UV photons of the right energies to dissociate some isotopes but not others, etc.: On a larger scale, such isotope variations among different solar system objects do not define a single relationship, suggesting that different paths or processes may have occurred. Some oxygen isotopic enrichments are 300% and even 6000% above normal. We still dont know much about the infancy of our solar system, Marty said, pointing to the future: and there is little doubt that tremendous advances in our understanding of this period will arise from the combination of high-precision microanalysis of extraterrestrial matter and of missions returning samples to Earth. 1Bernard Marty, Planetary Science: The Primordial Porridge, Science, 5 May 2006: Vol. 312. no. 5774, pp. 706-707, DOI: 10.1126/science.1125967. OK, so now will they go back and revise all the textbook illustrations, slide sets, posters, planetarium shows, and TV programs to reflect the fact that all the models were wrong, and we really dont know what happened in some past eons? No way; it would stir the pot and put the heat on too much for public consumption.Doctors Deny Darwin 05/05/2006 ![]() Doctors and medical professionals may comprise the largest block of scientists with qualms about evolution. According to a Finkelstein poll, an average of 60% of doctors, depending on religious demographics, reject the completely unguided Darwinian evolutionary explanation for life. A new organization, Physicians and Surgeons for Scientific Integrity (PSSI), has begun a website Doctors Doubting Darwin where medical professionals are invited to sign the following statement: As medical doctors we are skeptical of the claims for the ability of random mutation and natural selection to account for the origination and complexity of life and we therefore dissent from Darwinian macroevolution as a viable theory. This does not imply the endorsement of any alternative theory.Evolution News had a report on these developments. Another doctor raised a strong voice against the fruits of social Darwinism. Dr. C. Ben Mitchell, writing for Baptist Press, sternly denounced the National Institutes of Health for giving a school $773,000 to develop guidelines for the use of human subjects in what could be the next frontier in medical technology genetic enhancement. Mitchell says that to all familiar with the horrors of eugenics that led to the Nazi holocaust, and who joined in the chorus never again, this is a dangerous development. After reminding his readers how the original atrocities began with the most benign intentions, he warns, This grant does not merely cross a moral line in the sand, it uses your tax dollars and mine to demolish a brick wall 10-feet wide, turning it to rubble. We must protest the use of our tax dollars for genetic enhancement research of any kind. How soon we forget. We must not! Less than two months ago, Professor Ernst-Ludwig Winnacker, President of Deutsche Forschungsgemeinschaft (DFG), lamented the willing cooperation of doctors and scientists in the Nazi regime:Solar Eclipses Unique to Earth, SETI Researcher Finds 05/04/2006I must admit that it strikes me as bitter and disturbing that we ... at the DFG can find barely a trace of resistance, no outcry against the exclusion of Jewish scientists and their expulsion from universities, not a murmur against the abuse of agriculture and humanities for the criminal purpose of displacement of nations in Eastern Europe, no questioning of the execution or the purpose of medical experiments. Rather, the radicalisation of science in the service of the Nazi regime was evidently sanctioned without query.The ability of educated and otherwise rational people to quickly descend into hideous depths of human depravity for the sake of an ideology was shockingly illustrated in a sobering article by John Kekes in City Journal. He retold the story of Robespierre, dictator during the Terror of the French Revolution, who rationalized unbelievable acts of human violence, cruelty and debauchery in the name of reason and liberty. Kekes draws parallels with later ideologues of the Communist era, and todays terrorists, to warn us that we must never assume such things could never happen again. This article is a must read. (The contrast with the American Revolution is most instructive.) ![]() Like many before him, Seth Shostak pondered the significance of total solar eclipses for the one planet with observers to appreciate them. OK, Ive done the math, the SETI Institute director said for SETI Thursday on Space.com. What you always suspected might be true ... is true: namely that the best place in the solar system to see a total solar eclipse is Earth. Shostak appeared briefly in the intelligent-design film The Privileged Planet, which makes a case that the universe and earth are designed for discovery, not only for habitability. An evolutionist, Shostak was not promoting the premise of the film, but merely pointing out that unless the the earth were very special miraculous almost we should expect that other beings like us would inhabit the universe. Shostak subsequently tried to differentiate the work of SETI from that of intelligent design, however (see 12/03/2005) a comparison made in another Illustra film, Unlocking the Mystery of Life. Undoubtedly he has been dogged by questions from listeners about how SETI differs from the principles of design detection promoted by I.D. In this article on solar eclipses, however, Shostaks own research arrived at two similar conclusions stated in the film: (1) solar eclipses have allowed humans to make significant scientific discoveries, such as the detection of helium and confirmation of Einsteins theory of relativity, and (2) the presence of a moon like ours able to produce eclipses is probably linked to the hability of our planet. If tides really do encourage life, then worlds with tides similar to ours are also likely to enjoy total eclipses, he conjectured. Maybe eclipse chasers are a common cosmic breed. He came to the same conclusions because the conclusions are scientifically reasonable and based on observational facts. What is shameful is that Shostak gave no credit for prior research done more thoroughly on this question by Guillermo Gonzalez and Jay Richards in the book The Privileged Planet. He pretends as if he were the first to think of these things. He obviously knows that he appears in the film, and undoubtedly has watched it and understands its notoriety in the mainstream scientific community. So we challenge Seth Shostak to come forward and admit that he got his best ideas (that design detection is a scientifically valid reasoning process, and that the earth is designed for discovery) from his predecessors in the intelligent design movement. Intellectual property demonstrates the ontological character of information. Acknowledging someone elses intellectual contribution is the only ethical thing to do (and ethics dont evolve).Hope for Titan Ocean Evaporates into Ice Desert 05/04/2006 ![]() Saturns moon Titan is a desert of sand made of ice grains mixed with hydrocarbons. These grains form large fields of wind-driven dunes found over much of the planet-sized moon. Titans Seas Are Sand, reported a press release from U of Arizona based on a paper in the May 5 issue of Science (see Perspective by Nicholas Lancaster1 and paper by Lorenz et al.2). Until a couple of years ago, scientists thought the dark equatorial regions of Titan might be liquid oceans, the press release states. New radar evidence shows they are seas but seas of sand dunes like those in the Arabian or Namibian Deserts, as shown in the cat scratches soon detected on radar scan images. The grains are probably eroded from the water-ice mountains as infrequent downpours of liquid methane roar down the slot canyons onto the plains. Another surprise is that a moon this far from the sun could have enough solar energy to produce dune-sculpting winds. The answer is that Saturn sets up strong enough tides in Titans atmosphere to do the work. Though only on the order of one mile an hour, the winds in the thick atmosphere are able to transport the coffee-ground-size particles into familiar looking linear dunes. Today also some exciting visuals came from the Cassini and Huygens teams. New dramatic animations, based on actual photos, of the descent of the Huygens probe onto the surface (01/15/2005, 01/21/2005) give the viewer a probe-eye view of what it must have been like to ride the craft all the way to the dry lakebed. Go to: JPL Cassini or U of Arizona Lunar and Planetary Lab. Our favorite: JPL Titan Descent Data Movie with Bells and Whistles (you might want to provide your own blockbuster movie soundtrack to replace the electronic sounds representing the image sequence and signal strength). For a higher-res version of this information-filled wild ride, see the ESA Huygens site. For sheer drama and beauty of the descent, with Beethoven music to match, watch movie #3 at the DISR site. Some versions of the movies add captions and narration and are available in WMV and Quicktime formats, and there are high-res stills also. The bloggers at Unmanned Spaceflight are impressed. 1Nicholas Lancaster, Linear Dunes on Titan, Science, 5 May 2006: Vol. 312. no. 5774, pp. 702 - 703, DOI: 10.1126/science.1126292. 2Lorenz et al., The Sand Seas of Titan: Cassini RADAR Observations of Longitudinal Dunes, Science, 5 May 2006: Vol. 312. no. 5774, pp. 724 - 727, DOI: 10.1126/science.1123257. What an incredible finish to one of the biggest adventures in interplanetary exploration. The worlds strangest moon, one that long-age scientists were convinced had to be covered with a liquid ocean, is dry. Despite Titans bizarre color, orange you glad Huygens was a smashing success?Will Genetics Be Neo-Darwinisms Downfall? 05/04/2006 ![]() The Institute for Creation Research is gearing up for a multi-year GENE project to look for evidence for design (and against evolution) in the genome. They may not need to work very hard. Secular scientists, by continuing to find things not all that helpful for neo-Darwinism, are doing yeomans work for them. While the few pro-evolutionary articles usually focus on mere sources of variation in the genome as fodder for natural selection (such as this Molecular Biology and Evolution paper on retrotransposons), or try to infer phylogeny by molecular comparisons, they usually do not attempt to apply the variations to actual functions except at a trivial level (see 04/06/2006). Most genetics papers, by contrast, are finding degrees of order, regulation and coordinated action in the cell that challenge gradualistic explanations. Here are some examples from the past two months:
Darwinists are fond of storytelling with glittering generalities. When challenged, they retreat into accusations that anything other than 100% pure materialistic Darwinism is religion, not science, and use other shifty-feet tactics. The answer is to pile on the evidence. These articles are the tip of a truckload of data-rich, fact-filled laboratory studies that shout design instead of evolution. Lets rid secular science of its bad storytelling habit, and let the evidence speak for itself. The Darwinists are sliding downhill with an avalanche of data racing down against them. Perhaps a better cartoon of their predicament is to picture Wiley Coyote hanging by his fingers on a cliff. Jonathan Wells, by debunking the icons of evolution, is like the Road Runner lifting Mr. Coyotes fingers one at a time, while the genetic evidence is like Tweety Bird simultaneously piling weights on his feet. Pretty soon he fall down go boom.Soviet Cosmonaut No Atheist 05/03/2006 ![]() World Magazine reported a surprise tidbit from history, to set the record straight: the first man in space was no atheist. According to an urban legend, Yuri Gagarin, who flew a Soviet rocket in 1961, said that he didnt see any god up here in space. The quote has provided fodder for preachers ever since on the senselessness of atheism. Alas, poor Yuri; it appears now that he was a believer and never said such a thing. According to World, a professor at Russias air force academy, Valentin Petrov, claims that Gagarin was baptized in the Russian Orthodox Church and was a believer whose roots strongly influenced him. The source of the spurious story was apparently some kind of game. Other sources attribute the claim to Nikita Kruschev (see SOS Globe and Free Republic, for example). Well. What do you know. What do you know well? Maybe you have repeated this story without knowing the facts; we all do that sometimes (email forwarding is one of the most unreliable sources of truth). Its nice to know the first man in space was not so dumb as to imagine that if he couldnt see God in earth orbit, then God must not exist or to even expect that God would be visible at all. Not enough details were provided to know precisely what Gagarin did believe, but this can be a lesson for us in not always trusting (and parroting) claims we hear. A Google-search on Yuri Gagarin Valentin Petrov God will list many additional sources to check. Student Entries The following five articles were submitted by college students as an extra credit assignment. Welcome the upcoming investigative reporters!
Comparing Preferences for Pain or Gain 05/03/2006
1New Study Finds Similarities Between Monkey Business and Human Business, Science Daily. Source: Journal of Political Economy, University of Chicago Press Journals. In nature, animals act according to greatest benefit. For example, when wolves hunt elk, they do not tend to attack those which are strongest and largest. This is dangerous, and could lead to the escape of the elk, wasted vital energy of the wolves, and even death of the wolves. So what do researchers observe? Wolves tend to attack those old, straggling elk; or they attack those males who expended too much energy in mating season. For what reason? This is more beneficial to the wolves.Limbed Snakes Initiate Evolutionary Quandary 05/03/2006 ![]() Researchers have discovered the fossil of a snake with a pelvis and functioning legs in Rio Negro, Argentina. Sebastian Apesteguía (Argentine Museum of Natural Science) says Najash rionegrina is not the oldest snake discovered; marine snakes have been discovered in North America as well as Eastern Europe. However, Najash rionegrina has been considered the earliest limbed snake found in terrestrial sediment. According to Nicholas Bakalar (National Geographic News):1,2 Early snakes, the theorys supporters say, are closely related to scolecophidians, a living group of primitive land snakes that still have vestigial pelvic regions. But proponents of a watery origin believe that snakes most likely evolved from extinct marine reptiles called mosasaurs, powerful swimmers that spent their entire lives in the ocean. Snakes probably evolved during the Jurassic150 million years ago, Apesteguía said, but there are no fossils. During the early Cretaceous120 million years agothey exploded [into] several forms, including some terrestrial like Najash, ...and some aquatic. The fossil record shows that terrestrial and aquatic snakes both existed by the mid-Cretaceousabout 95 million years agoleaving researchers unsure about which type evolved first. The question, Apesteguía said, is, Which is more primitive, the terrestrial Najash or the most primitive water snakes, a group called pachyophids? He points to evidence that marine snakes are less primitive: Their skull bones suggest that they could expand their mouths to ingest larger preya characteristic of modern snakes. The marine snakes, Apesteguía concludes, are ancient versions of modern snakes, not really primitive. 1Snakes Evolved on Land, New Fossil Find Suggests, National Geographic News, Accessed April 23, 2006. 2Snake Ancestors Lost Limbs on Land, Study Says, National Geographic News, Accessed April 23, 2006. It is not a surprise that evolutionists cannot decide between an aquatic or terrestrial origin for snakes. Although researchers have realized that marine and land snakes existed at the same time, they have only accepted this coexistence to an extent. In fact, Sebastian Apesteguía has stated that the evidence of transition fossils does not exist. As a result, Apesteguía and other researchers, including Hassum Zaher (University of Sao Paulo in Brazil), are uncertain about the position of either species on the evolutionary chain. Zaher suggested that limbed snakes are related to pythons and boas and not marine snakes. This conflicts with Apesteguías allusion to an aquatic origin. The discovery of Najash will only rekindled the flame of controversy as evolutionists attempt to avoid another kink in their chain.Can We Not Perform Similar Functions? 05/03/2006 ![]() Researchers from Kings College London claim their data evidences the Human [thyroid] gland probably evolved from gills.1 According to speculation, gills were internalized as the thyroid gland when marine life evolved into land animals. The possibility for this comes from the similar functions of gills and of the gland: both act as calcium level controls. The gills act to pump calcium into the body. The thyroid gland secretes parathyroid hormone when calcium levels drop, causing bone stores to release calcium. Therefore, researchers had a basis for their work, a reasonable pursuit in their evolutionary mindset, according to Professor Graham. Further support included positioning of the gills vs. the thyroid gland: in the human neck, and near the head of the fish. The researchers compared the gills of zebra fish with those found in various mammals. They found the tissues development from pharyngeal pouch endoderm, an early embryonic tissue. The tissues also express two similar genes related to development, Gcm-2, and to functioning as a gland, expressing a gene for parathyroid hormone. This evidence suggests, the article ends, humans do have a sort of gill after all. [Its] still sitting in our throats, finished Dr. Graham. 1Human Thyroid Gland Probably Evolved From Gills, Science Daily. Science Daily, posted: December 7, 2004. The information in this article is presented with an evolutionary mindset. All creatures come from common ancestors; therefore similarities seem to indicate homology. The thyroid gland evolved from a marine organisms gills, as fish came first, then mammals. Functions of the higher organisms somehow relate to those of lower organisms. Creationists assume that organisms have similar genes due to performing certain similar functions. Evolutionary explanations employ circular reasoning: These animals came from common ancestry. Why? Because they have similar functions. Why do they have similar functions? Because they share common ancestry. The creationist is compelled to ask, Should God make his creation obscure, unrelated, and unconnected, so as to be incomprehensible to the observer? So as to disprove evolution, should God have made every single creature with its very own oxidative pathways, tissues, and building blocks of life (i.e. nucleic acids, proteins, carbohydrates, lipids)? |
