Darwinists sometimes claim that their theory helps us to understand which animals are most closely related... on the basis of their genetic and biochemical similarities. But this is just comparative biology at the level of genes and proteins. Linnaeus did comparative biology, yet he was a creationist who lived a century before Darwin; Owen and Agassiz did comparative biology, yet they rejected Darwins theory. | |||||||||||||||||||

![]() Why engineer things from scratch, when we can imitate nature? Two recent examples come from the world of insects. A press release from UC Berkeley begins, Using the eyes of insects such as dragonflies and houseflies as models, a team of bioengineers at University of California, Berkeley, has created a series of artificial compound eyes. (Emphasis added in all quotes.) Insect eyes use thousands of facets to get a wide field of view without distortion. How can humans use this technology? Potential applications include surveillance; high-speed motion detection; environmental sensing; medical procedures, such as endoscopies and image-guided surgeries, that require cameras; and a number of clinical treatments that can be controlled by implanted light delivery devices. Anyone who has missed swatting a fly knows that the insects have these first three applications down pat. The authors published their work in Science this week.1 Human committees have a hard time arriving at a consensus about what is the best solution to a problem. Maybe they should learn from bees. Ten thousand of them swarming chaotically somehow converge quickly on a solution to the problem of the best location for a new hive. A press release from Cornell University says that they have a unique method of deciding which site is right: With great efficiency they narrow down the options and minimize bad decisions. How? By coalition building till a quorum develops, the article explains. The scientists found that bees use their famous waggle dance not only when shopping for food, but when scouting for real estate. The researchers watched 4,000 scouts report back to the hive from various directions. The superior site usually was not the first one chosen. In a 16-hour process, the swarm came to agreement and found the best solution. This is a striking example of decision making by an animal group that is complicated enough to rival the dealings of any department committee, said Thomas Seeley, Cornell biologist. What can managers take home from this nature lesson? Include an open forum of ideas, and employ frank discussions and friendly competition. This quorum-setting method of aggregating independent opinions might help achieve collective intelligence and thus avoid collective folly. 1Jeong et al., Biologically Inspired Artificial Compound Eyes, Science, 28 April 2006: Vol. 312. no. 5773, pp. 557 - 561, DOI: 10.1126/science.1123053. Funny, honey; none of these articles mentioned evolution, but they seemed to have no problem using the word design.Non-Coding DNA Has Far More Complexity Than Was Imagined 04/27/2006 ![]() The concept of junk DNA appears to be fading away. A mathematical analysis of the human genome suggests that so-called junk DNA might not be so useless after all, reported Paul Rincon for the BBC News. The photo caption reads, The genome may possess far more complexity than was imagined. A team from IBM found motifs involved in regulation of the genes. These showed a relationship between functional areas of the genes and those not previously considered functional. Certain structures, called pyknons, are apparently involved as RNA silencers that turn genes off or on in complex ways, even after a gene has been translated. More detail and an illustration is provided at the IBM Research press release. These regions may indeed contain structure that we havent seen before, said Dr. Isodore Rigoutsos. If indeed one of them corresponds to an active element that is involved in some kind of process, then the extent of cell process regulation that actually takes place is way beyond anything we have seen in the last decade. The paper by Rigoutsos et al. was published in PNAS.1 1Rigoutsos et al., Short blocks from the noncoding parts of the human genome have instances within nearly all known genes and relate to biological processes, Proceedings of the National Academy of Sciences, published online before print April 24, 2006, 10.1073/pnas.0601688103. Geneticists would have been way ahead of the curve if they had listened to IBM instead of Dawkins. The average lab does not have the resources to prove or disprove this, so it will need a lot of effort by lots of people, said Dr. Rigoutsos. Not only are Information Technology (IT) people better suited to understanding codes, they might even benefit from imitating natures programming tricks. Lifes code works, doesnt it? Look at a bird, or a butterfly, or a human baby. Most of the time the right parts come out in the right places, generation after generation, for thousands of years.Hominid Claim Is More Philosophy Than Fossils 04/27/2006 ![]() Two weeks ago, the media had a feeding frenzy over Tim Whites claim that his team found bones in Ethiopia from three hominid species lined up in a vertical row, showing a clear progression toward humans. Now, the fine print has come out. A review in Nature1 begins, Deciding whether our ancestors evolved as a single lineage may depend more on philosophy than fossils (emphasis added in all quotes). Rex Dalton wrote some juicy lines in his article that creationists will love, and evolutionists will insist are taken out of context (because evolution is a fact). You be the judge:
1Rex Dalton, Feel it in your bones, Nature 440, 1100-1101 (27 April 2006) | doi:10.1038/4401100a. Didnt we foretell this? Go back to April 12 when all the news media were slain in the spirit over Whites holey relics. We warned that the field of evolutionary paleoanthropology is filled with rivalry, contradiction, deception, exaggeration and outright fraud. Notice that Daltons depiction of rivalry applies not just to this case, but to various phases of hominid evolution indeed, all of them.Unconstant Constant Could Challenge Basic Physics 04/27/2006 ![]() Shifting constant could shake laws of nature, said Mark Peplow in Nature.1 From the speed of light to the charge on an electron, the fundamental constants of physics had been assumed to be immutable, he continued. But that comfortable assumption is being challenged. The latest challenge is ratio of the mass of a proton to the mass of an electron (1,836); some Netherlands scientists who compared light from distant quasars with ultra-precise lab data claim it is decreasing. The estimated decrease is small just 20 parts per million over 12 billion years but if accepted, could produce new ideas on how the universe is put together. Such an effect is not explained by anything in physicists standard model of particle physics, Peplow said. This story also made news of the week in Science magazine.2 1Mark Peplow, Shifting constant could shake laws of nature, Nature 440, 1094-1095 (27 April 2006) | doi:10.1038/4401094a. 2Adrian Cho, Skewed Starlight Suggests Particle Masses Changed Over Eons, Science, 21 April 2006: Vol. 312. no. 5772, p. 348, DOI: 10.1126/science.312.5772.348 CEH leaves this controversy for others to debate, but mentions it for those interested in shaking the pillars to make sure theyre rigid (or not) as Andy Fabian (U of Cambridge) is quoted as saying in the article. Sometimes the most confident things in science become less confident as more knowledge is gained. If we are not sure about constants of physics, how much less so for shaky, slippery things like evolutionary theory?Stupid Evolution Quote of the Week: Astrobiology Takes on I.D. 04/26/2006 ![]() The Center for Astrobiology at the University of Boulder is hosting a symposium today entitled, Fossils and Genes: Exploring the Evolution of Life. Douglas Futuyma (State University of New York) calls Evolution the most important theory in biology. By his own admission, though, it is a theory filled with paradoxes: Evolution is both a fact and a theory: the most comprehensive explanation of the features and diversity of living things. It is the most important theory in biology, yet is surrounded by paradoxes. Despite the simplicity of its central concepts, evolution has a long history of misunderstandings. Despite its lack of moral or prescriptive content, evolution has been used to justify social policies that range from the admirable to the appalling. Despite the increasingly important role evolutionary principles and knowledge play in human biology, evolution is rejected by more than half the American public. Of all the biological disciplines, evolutionary biology has the most far-reaching philosophical implications and the most diverse applications to society. (Emphasis added in all quotes.)He is joined by Warren Allmon (Cornell), speaking on Evolution, Intelligent Design, and the Uneven Search for a Consistent World View. Darwin succeeded where others before him had failed in part because he offered the first truly scientific (i.e., purely materialistic and therefore testable) theory to explain the history of life. He permanently changed the terms on which theories in biology would be acceptable as science. Yet few of Darwins contemporaries or those who followed truly internalized Darwinism into a coherent and consistent world view. Materialistic science is vastly more important to modern society than it was in Darwins time, yet scientists and non-scientists alike still struggle to fully reconcile materialistic science with their personal and social search for meaning in life. On the one hand, proponents of intelligent design have declared their intention to overthrow materialism and its cultural legacies, which presumably would include not just Darwinism but also everything from agriculture to modern medicine [sic]. On the other, many mainstream scientists both those who claim to be religious and those who do not have attempted to reconcile their scientific pursuits with their non-scientific personal philosophies. Can one simultaneously hold two mutually exclusive philosophies of reality one materialistic and the other not? If so, how? And does doing so make one intellectually dishonest? Is it possible to construct a logically consistent world view that fully accommodates meaningful religious belief with materialistic science?Sounds like Allmon has quite a challenge before him and so does Futuyma. Notice several flaws, contradictions, and admissions in these abstracts.UNESCO To Rebuild Mystery Babylon 04/26/2006 ![]() The United Nations has plans to make ancient Babylon a tourist attraction. This International Herald Tribune article will be of interest to Biblical historians. ...and maybe to prophecy buffs.Sea Monster Found Under Davy Yones Locker 04/25/2006 ![]() The deepest dinosaur bone ever found, a part of a Plateosaurus, has been found by Norwegians 1.4 miles under the North Sea floor. This sets a new depth record for a dinosaur fossil. According to LiveScience, Researchers said its quite possible there are many more fossils down there. More on National Geographic News, News@Nature and the BBC. A four-ton land rover buried in sediment a mile and a half under the seabed think about it. Does this sound like the setting described in the article: dry plains with rivers running through them? If the dinosaur lived in that environment, what happened? Meanwhile, they should look for more down there. What if the dinosaur fossils we find on the surface represent a tiny fraction of bones buried deep under the sea, all over the world?Walking Snake Bites the Dust 04/24/2006 ![]() It must be missing link season. MSNBC News announced a snake with rudimentary legs. While exciting for evolutionary theory, it raises questions, too. Snakes were supposed to have evolved in the water, not on land. Check out what Ken Ham said on Answers in Genesis about this latest salvo. If the snake had legs, does the evolutionary claim have any?Paper View: Cambrian Explosion Damage Control 04/23/2006 ![]() Like some federal official holding a press conference after a disaster, a Harvard paleontologist has tackled the unenviable job of explaining what Darwin called the most severe challenge that could be levied against his theory: the fossil record. The challenge starts with a bang. Right near the beginning, virtually all animal phyla appear abruptly without ancestors: the so-called Cambrian explosion. An evolutionist, devoted to a theory expecting to find slow and gradual change, has no small challenge explaining this event. Its made all the more difficult by critics of evolutionary theory, like angry reporters asking tough questions, pointing out what the Darwin administration said vs. what the cameras show. This is no job for a junior spin doctor. Dr. Charles R. Marshall has the credentials to be a good press secretary: Department of Earth and Planetary Sciences, Department of Organismic and Evolutionary Biology, and Department of Invertebrate Paleontology, Museum of Comparative Zoology at Harvard. Writing in the May issue of the Annual Review of Earth and Planetary Sciences,1 he gives what amounts to a State of the Cambrian Explosion address. Will he be the man of the hour, the master of disaster? Many in the audience have not been happy with the Darwin administration. As evidence of the need for regime change, they point to the failure to explain the sudden appearance of virtually all animal body plans in the Cambrian, the lowest layers of fossil-bearing strata. Duane Gish and Henry Morris pounded evolutionists on this point in their decades of debates. It was the subject of Stephen Meyers notorious exposè (09/24/2004) that made the Darwin administration look like censors. It was one of the Icons of Evolution defaced by Jonathan Wells. From the earliest criticisms of Darwins book to the cover of Time magazine in recent years, Biologys Big Bang has been one of evolutionary theorys biggest embarrassments. Enquiring minds want to know; can Darwinian scientists deal with this? Aware of the opposition (as he must be), will Marshall describe the problem honestly and accurately? Will his presentation confirm the viability of the ruling partys program? Will the applause be hearty or tepid? Stepping up to the journal podium, he begins his paper: The Cambrian explosion, or radiation, is perhaps the most significant evolutionary transition seen in the fossil record. Essentially all of the readily fossilizable animal body plans first appear in the fossil record during this interval (Valentine 2002). We move from the depths of the Precambrian world, where the sedimentary record is essentially devoid of animal fossils, to the Phanerozoic, where animal life leaves pervasive evidence of its existence, both as body fossils and as disturbers of the sediment.And thus he dives right in. One notices right off the bat his habit of putting explosion in quotes. This is because, while the Cambrian radiation occurred quickly compared with the time between the Cambrian and the present, it still extended over some 20 million years of the earliest Cambrian, or longer if you add in the last 30 million years of the Ediacaran and the entire 55 million year duration of the Cambrian. This attempt to downplay the seriousness of the damage would surely elicit some boos from the gallery. One of Marshalls authorities, Dr. James Valentine, whom Marshall admits did a masterly treatment of the origin of phyla (see 07/29/2004) said it was 10 million years, or maybe even 5 million, when interviewed for the film Icons of Evolution.2 But even given the widest latitude of time, Marshalls own diagram in the paper shows new phyla appearing abruptly without ancestors at various points within the timeline. Trilobites, for instance, show up at about 525 million years, and no pre-trilobites have ever been found. Marshall provides some background and a timeline of the Cambrian radiation (as it is also called). He delves into the Precambrian looking for ancestors. He discusses the strange Ediacaran creatures (see 08/19/2004); no one is sure, however, if these are even animals, and even if they were, they seem to have gone extinct before the explosion, without having any relationship to the complex animals that followed. Marshall portrays a sequence (but not necessarily a phylogeny) of the explosion in slo-mo. Traces in the rock, first 2-dimensional then 3-dimensional, appear right before the Cambrian boundary. Next, some small shelly things appear which might be either new animals or broken bits of molluscs and brachiopods. Then, boom: large, morphologically diverse taxa. These include the trilobites and echinoderms, and all the wondrously diverse organisms found in the Chengjiang biota of China. By the time of the Burgess Shale formation (Canada), less than 10 million years later, the Cambrian explosion is all but spent. (He forgot to add the quotes that time). Well abbreviate it CE from here on. Can we trust the fossil record, though? Could the CE just be a selection effect, an artifact of what animals happened to get fossilized? He seems to agree with Valentine and colleagues (1991) who, in the only quantitative treatment of the suddenness of the Cambrian explosion, conclude that the suddenness of the adaptive radiation is real, even when the incompleteness of the fossil and rock records is taken into account. But he speculates that it is likely that evolutionary lineages have their origins in rocks older than their first observed occurrences in the fossil record. The only evidence he offers is that attempts to use molecular clocks to estimate the time of origin of the animal phyla (what he calls a subtle and difficult art because different clades may evolve at different rates) have led to much larger estimates of the incompleteness of the fossil record (see 04/20/2004). Strangely, he brings these two conflicting data sets into accord without evidence: first, by asserting the fact that the divergence times of lineages (which molecular clocks estimate) may significantly predate the time of emergence of diagnosable morphologies (which the fossil record estimates), and second, by stating flatly that all agree that the phyla have at least some Precambrian history. Both these assertions assume evolution. To set up the problem of the Cambrian explosion (quote marks or not), Marshall outlines the aspects that need explaining: There are five major components of the Cambrian explosion that need to be explained: (a) the spectacular increase in animal disparity, (b) the rise in animal diversity,3 (c) why the time of onset of the explosion was some 543–542 mya, (d) why the duration of the explosion was some tens of million years long, and (e) why the event appears unique.Marshall mentions that the CE is not the only spectacular radiation in the record. He mentions the large increases in diversity in the Ordovician, Paleozoic, Mesozoic and Cenozoic; there are many other major events in the history of animal life other than the Cambrian explosion, he reminds the reader. The unique thing about the CE is that all the later radiations are variations on body plans already established in the Cambrian. (It is also puzzling why he would point to more explosions to help explain this one.) The remainder of Marshalls paper can be divided roughly into two parts. The first examines all the proposed explanations for the CE, including their relative strengths in explaining all seven aspects listed above. These he shows to be inadequate. The second part gives his own personal explanation. We now summarize part one: here is why, in his opinion, the other explanations fail in one way or another (although, he suggests, each might contribute partial explanations):
It is clear that the environment must be permissive of animals before they could have evolved. It is also clear that the genetic machinery for making animals must have been in place, at least in a rudimentary way, before they could have evolved. And finally, organisms must be able to leave viable offspring to survive and evolve, so ecology had to be important too.Now to the climax. Marshall embarks on a five-page description of his own explanation. Surprisingly, however, he says very little about actual fossils only one paragraph about where the Ediacaran biota might fit in. His framework for integrating environmental, ecological and developmental data is almost completely theoretical. He launches off from Sewell Wrights concept of the fitness landscape, on which peaks represent higher evolutionary fitness, and valleys lower fitness. Heres a new word for you: Fitness Landscapes (of the Morphogenetic Kind). Knowing that morpho- refers to body or structure, and -genetic refers to origin or begetting, is Marshall suggesting that a fitness landscape can invent a body? Apparently so. Watch carefully: Following the rich tradition begun by Sewell Wright (1931, 1932), fitness landscapes provide a fruitful way of thinking about the interaction between developmental potential and evolutionary success, the ability to pass ones genes on to the next generation. The coordinate system in most fitness landscapes is based on genes and their alleles. However, the Cambrian explosion finds its expression in the fossil record morphologically, so it is more appropriate to use a morphogenetic rather than a genic coordinate system. Hence, theoretical morphospaces (McGhee 1999), where each axis of the landscape represents a distinct morphogenetic rule and where the position along each axis corresponds to a particular variant of the rule, is appropriate here. Every point in the space corresponds to a unique morphology that arises from the morphogenetic rules.Marshall seems to be saying that a morphogenetic rule some kind of body-building principle in nature will automatically give rise to new animals (given a rudimentary genetic toolkit), just from the existence of needs. In his words, if we assign a fitness value to a morphology (roughly, a body plan), evolution will explore the fitness landscape to deliver the body. Not only that, the fitness landscape itself evolves! Clearly, to Marshall, this is a situation pregnant with possibilities. He is quick to explain that the fitness landscape metaphor has limitations. First, movement [in the fitness space] is measured in terms of change in the morphogenetic rules, several steps removed from the genetic changes that are responsible for those rules, he explains. That is, there needs to be a connection between the outside environment and the inside coded instructions. However, we are still profoundly ignorant of how changes in the genome translate into changes in morphology, despite the spectacular advances we have made in understanding the genetic basis of morphogenesis. Somehow, it must happen; the information required to live on the outside must get coded on the inside. Thats somebody elses problem. For the remainder of the discussion, Marshall lets computer models work the miracles. Borrowing on computer models by Karl Niklas, he postulates that, if the fitness landscape can become roughened (i.e., with more and smaller fitness peaks closer together), interesting things can happen: increases in diversity and disparity may also be achieved... without the need for new genes and morphogenetic potentials. While that thought sinks in, let us ask, what factors can roughen the landscape? Heres the short answer: the number of needs the organism must satisfy. Plants, for instance, might need to perform realistic ecological tasks, including the ability to produce and disperse seeds, harvest light, avoid mechanical breakage of its branches, and minimize the risk of desiccation through minimizing its surface area. Necessity is the mother of invention. If you feel frustrated by this line of argument, Marshall turns that, too, to his advantage. He introduces the Principle of Frustration a thought so profound, he says, I have elevated its importance by labeling it a principle. What, you ask, is the principle of frustration? It captures the notion that different needs will often have (partially) conflicting solutions, so that the overall optimal design for an organism will rarely be optimal for any of the specific tasks it needs to perform (i.e., there are trade-offs). In other words, its the old engineering principle of constrained optimality. Consider a laptop computer, for instance.5 A big screen is good, but conflicts with the need for compactness and light weight. Heavy-duty peripherals are good, but conflict with the need for long battery life. So in Marshalls context, a plant or animal is going to have conflicting needs in order to survive, so evolution will explore the fitness landscape, and produce the morphology that provides the best trade-offs in order to ensure survival.6 The main point Marshall wants to get across is that the rougher the landscape, the better. Rough landscapes are evolutionary playgrounds. In his words, The key point is that when all tasks need to be performed, the trade-offs combine to produce a wide range of local optima, given the rules for making the plants. Thus, it is frustration that leads to an increase in the roughness of a fitness landscape as the number of needs increase (Figure 3). While the number of local optima in a fitness landscape will clearly depend on the specific morphogenetic system (e.g., whether we are dealing with plants or animals, etc.) and on the range of environments that system finds itself in (e.g., terrestrial, aquatic, polar, tropical, etc.), the roughness of the landscape will also usually depend on the number of needs that must be met, or tasks that need to be performed.More small peaks, therefore, yield more diverse and disparate inhabitants sitting on them. Yet how can a peak, large or small, produce an optimally-engineered creature sitting on top? The sherpa, the engineer, the innovator, the outfitter, the creator is: EVOLUTION. That is the hero of the story: evolution actualizes the body plans that the real world constrains. Is that not echoed in the end of the Devonian, the period of greatest gross morphological innovation in the terrestrial invasion by plants? It must be. The Niklas computer model showed it could be so. The startling possibility is that evolution has found essentially all the locally optimal ways of being a terrestrial plant (ignoring the fine morphology associated with leaves, reproductive organs, roots, etc., as well as major modifications in the way living plants grow and reproduce compared with these early plants), and that it explored the morphogenetic space in just about one geological period. The Niklas study opens up the possibility that evolution is able to find essentially all the locally optimal morphologies consistent with a given underlying developmental system on geological timescales. That is, all the processes associated with variation (point mutation, recombination, hybridization, gene conversion, insertion and deletion, post-transcriptional changes in mRNA processing, etc.) are able to effectively explore fitness landscapes on geological timescales; evolution is able solve [sic] the np-hard problem of exploring the rich combinatorial potential embedded in the genome in the order of 10-20 million years.What an amazing scout, this evolution. Engineers must be envious. Marshall has turned the tables. At the end of a difficult speech, begun facing angry reporters asking tough questions, he is in control. Viewing the Cambrian explosion in the context of the evolution of fitness landscapes, he grins, opens up the possibility that uniqueness of the Cambrian explosion may simply represent the exhaustion of ecologically viable alternatives that can be generated by the bilaterian developmental system... Simple, isnt it. Thats all there is to it. Whats the problem? The reporters are writing as fast as they can to get this down. Once upon a time, the landscape was filled with fitness peaks, and as they got rougher, evolution obliged by filling them. Good enough for a sound bite. But what about information in the genes for these new body plans? asks one mythical reporter. Where did it come from? No problem, is the confident response; the information was already there: As discussed above, Marshall continues, the phylogenetic distribution of key developmental genes in living species suggests that the basic developmental toolkit, a combinatorial toolkit, for bilaterian animals was already in place prior to the radiation (Carroll et al. 2001), certainly before the end of the Ediacaran. Take the Lego blocks, sprinkle them onto a roughened landscape, and the rest is history. (Where the toolkit came from is thus pushed farther back into the past, as someone elses problem.) This calls for a new creation myth. Here is the new Genesis or, shall we say, the Book of MorphoGenesis. Marshall starts a new paragraph entitled, The Arms Race Roughens the Garden of Ediacara. In the beginning, there were peace-loving Ediacaran organisms in paradise; innocent and blind, without knowledge of good and evil. But a time of testing came. Instead of a Biblical serpent, some generic predator appeared on the scene, and frustration entered the world: With the advent of ecological interactions between macroscopic adults (especially interactions associated with predation)... the number of needs each organism had to meet must have increased markedly: Now there were myriad predators to contend with, and a myriad number of ways to avoid them, which in turn led to more specialized ways of predation as different species developed different avoidance strategies, etc. Even with no changes in the bilaterian developmental system as it existed by the end of the Ediacaran, the diversity and disparity of animals should have risen sharply, as the fitness landscape roughened in response to dramatic increase in the level of frustration (Figure 3). The combinatoric richness already present in the Ediacaran genome was extracted through the richness of biotic interaction as the Cambrian explosion unfolded (Marshall 2003). I offer this as a null hypothesis explanation for the Cambrian explosion.7In fact, Marshall continues, his model can even offer a prediction, as any good scientist should. Look east, my young disciple: It suggests that if we replayed the tape of life, with the same developmental programs, we would see similar morphologies each time: In the debate that sprung up across the Atlantic between the importance of contingency (Gould 1989) and inevitability (Conway Morris 1998, 2003) in the history of life (to oversimplify the issue somewhat!), perhaps the truth of the matter lies more to the East than most would be willing to grant.Exactly how one might test the prediction (replaying the tape of life) is not explained. Presumably, if there are no planets available for millions of years, one could play SimEarth. Alas, There are many issues that remain, he ends. How did a rough landscape actually generate new morphologies? If the principle of frustration worked so well at the Cambrian, why not at the Ordovician? What controlled the duration of the event? Is it simply the time it takes evolution to explore the landscape... or does the roughening occur piecemeal...? he asks. That is, is there a steady dance as the fitness landscapes of each of the major clades coevolve? And Why does phylum-level innovation die away as the Cambrian unfolds? Why didnt the explosion occur 100 million years earlier or later? To a skilled press secretary, these questions are not difficulties; they are opportunities. In summation, his last sentence announces, explaining the Cambrian explosion of bilaterian animals will remain a rich field of enquiry for quite some time to come! 1Charles R. Marshall, Explaining the Cambrian Explosion of Animals, Annual Review of Earth and Planetary Sciences, Vol. 34 (Volume publication date May 2006) (doi:10.1146/annurev.earth.33.031504.103001). 2It must be noted that the dating methods of evolutionary paleontologists all assume evolution and long ages. Creation scientists will argue that the dates are fallacious and falsified by their own research (e.g., see 11/05/2005). Nevertheless, this writeup will assume the long ages, to give the evolutionists their best possible conditions for explaining the Cambrian explosion. Even so, Jonathan Wells once remarked that, in geological terms, the event was so sudden and so brief, it would be like walking a football field and having all the animal phyla appear when stepping across the 60-yard line. 3Diversity means the number of species, whereas disparity is degree of difference between them. There may be a great diversity of trilobite species, for instance, but the disparity between a trilobite and a starfish or a dinosaur is much greater. 4Diploblasts have two organized cell layers, like corals and jellyfish. Triploblasts have three, with an outer ectoderm, middle mesoderm, and inner entoderm (which includes the gut). All the complex animals, (also called Bilateria, or animals with bilateral symmetry), including those appearing in the Cambrian explosion, are triploblasts. 5Jay W. Richards used this analogy in the Q&A extras on the film, The Privileged Planet, in discussing how the Earth is optimized for scientific discovery. 6This presumes the neo-Darwinian notion that passing on ones genes (survival) is a measure of fitness. When defined this way, fitness is a tautology: not only do the fit survive, whatever survives, by definition, is fit. 7A null hypothesis is a baseline or default explanation, against which other hypotheses can be measured. A null hypothesis for a new medication, for instance, might be, this medication has no effect. Its up to an experimenter to prove that it does, contrary to the null hypothesis. There is a little word, presto, with two meanings appropriate here. In music, it is a very rapid tempo. In entertainment, it is a magic word that produces rabbits out of hats and beautiful women out of gunny sacks stuffed into tiny boxes. Marshall has explained the presto tempo of the Cambrian explosion with a presto magic act. Discerning readers know it is just a trick.No Pain, No Gain Explained: Lactic Acid Supercharges Your Engines 04/21/2006 ![]() The old paradigm: lactic acid buildup during exercise is like poison to your muscles, producing stiffness and agony.

Instead, many pro-Darwin forces issue prepared statements, misrepresent their opponents, and use legal maneuvering to try to head them off at the pass. What they cannot ignore, however, is that large majorities in the public sector oppose the Darwin-only policy in education. That means the public also has become a target of abuse. This was obvious 17 months ago with the notorious National Geographic Nov. 2004 cover story, Was Darwin Wrong? answered inside with a paternal foot-stomp in bold 250-point type, NO (see 10/24/2004, 02/15/2005). Here are some recent examples in that same tactical style that treats the majority public as hopelessly backward peasants who, in this state of siege, need stern military discipline:
One of the most intriguing, dynamic and fateful cultural debates in recent history is taking place before our eyes. No one can afford to be uninformed.How Evolutionary Science Is Done: From Deduction to Story 04/20/2006 ![]() Evolution is a fact! Carl Sagan stated emphatically on TV in his 1980 Cosmos series (now in reruns on The Science Channel). Following this lead, many evolutionists repeat this four-word phrase, often augmenting it like, Evolution is a fact, like gravity (see association). This motto has some interesting properties in its effects on scientific research. Anything that is a fact no longer needs to be proved. It no longer needs evidence. It can be taken as a given, a first principle from which other principles can be deduced, and a framework into which all empirical data can be fitted. Has Charles Darwin become the new Aristotle? Here are some recent examples of evolutionary reasoning in scientific journals and science news articles. Look for instances of deducing conclusions from the premise evolution is a fact. Also look for reasoning that, since evolution is a fact, it must be capable of accomplishing any kind of design work found among the worlds amazing living creatures.
Cornelius Hunter, writing for ID the Future, has found this reaction to be common in his experience debating evolutionists. Evolution is a fact is their knee-jerk reply, with the inevitable comparison to gravity (an association Hunter calls absurd). As the old saying goes, it is not what a man doesnt know that worries me, he quipped, but what he knows for sure. He continued, The evolution is a fact claim is awkward for evolutionists. It makes the man behind the curtain all the more obvious and is empirically unsupportable. How should evolutionists respond when a savvy buyer starts kicking the tires and asks Why is this a fact again?....Hunter calls this an unfortunate trend in science. Lets reverse it and seriously engage the issues at hand. 1Sumbre, Hochner et al., Octopuses Use a Human-like Strategy to Control Precise Point-to-Point Arm Movements, Current Biology, Vol 16, 767-772, 18 April 2006. 2Scott L.

Were going to keep holding up this garbage to public view as we have for over five years now, to expose Darwinian research for what it is: institutionalized question begging, assuming what needs to be proved, making up tall tales in the absence of evidence, ascribing exquisite design to dumb processes of randomness, and murdering Baconian scientific rigor. Once the Darwin Party came to power, they dumbed down the high standards of research, substituted bravado for caution, and brought in the dark ages of speculative biology where facts and data dont matter any more. The highest value now is keeping the story line begun by Pope Charlie going ad infinitum. The usurping Darwin Party elitists not only lounge around, engaging one another in tantalizing speculations (12/22/2003) in the institutions once devoted to induction and proof, but then have the gall to condemn anyone who calls them on the carpet for their shenanigans.Ethiopian Missing Link: Location, Location, Location 04/19/2006 (Guest article) ![]() The Associated Press reported that a new fossil discovery proves the link between two ancestral species of man, and shows the change happening right before our eyes: Fossils have long provided snapshots of the human family tree, but a new find in Africa gives scientists a kind of mini home movie showing mans primal development.So what did they actually find? Not a missing link or an intermediate form, but just another Australopithecus anamensis fossil, but in a location intermediate in the rock layers between Australopithecus and its supposed ancestor Ardipithecus: The species, Australopithecus anamensis is not new, but its location is what helps explain the giant leap from one early phase of human-like development to the next, scientists say. All eight species were found in a region called the Middle Awash.Finally we get to the fine print and disclaimers. It turns out they arent so sure as the headline would like you to believe: While its looking more likely, it is not a sure thing that Ardipithecus evolved into Australopithecus, he said. The finding does not completely rule out Ardipithecus dying off as a genus and Australopithecus developing independently.This story was widely circulated in newspapers. In yet another example of circular reasoning, White and team have assumed evolution, fit the data to the evolutionary just so story, and paraded the result as proof that evolution happened. Evolutionists are so desperate to deal with the lack of intermediate fossils that now the location of a fossil qualifies it as somehow being intermediate. Arranging fossils in some increasing order of complexity to prove evolution has been around for a long time, for example, the horse evolution series, but it doesnt prove that evolution happened any more than arranging old cars in a junkyard in order of complexity proves they evolved.Step Aside, T. Rex: Bigger Dino Found 04/19/2006 ![]() A cache of dinosaur bones, meat-eaters bigger than Tyrannosaurus rex, has been uncovered in South America. National Geographic News says the new species, Mapusaurus, exceeded the former heavyweight carnivore in size and agility. All the bones in a river deposit were 100% from this one species, so the chances they had been deposited randomly are extremely low, said Rudolfo Coria, the discoverer. The skeletons showed no signs of disease, Coria says, so the animals were apparently victims of some sudden catastrophic event. The article says that even larger creatures may remain to be discovered. See also MSNBC News, which has comparative diagrams. What would bury a group of heavy, agile, strong, mobile, intelligent monsters suddenly? Think about it.Stupid Evolution Quote of the Week: Scientists, Learn Darwinism on TV 04/18/2006 ![]() In Current Biology, Kenneth E. Sawin of Wellcome Trust Center for Cell Biology at Edinburgh University was interviewed about his career. One of the questions was, What are the big ideas for you now? Here is part of his answer: Another thing that I think about, which may be more ethereal, is that cell biologists interested in molecular mechanisms should always be reminding themselves that evolution proceeds without any predestined direction, and this is as true for cellular regulatory mechanisms as it is for organismal evolution [sic]. Even if we dont think too much about evolution in our day-to-day work, it is the backdrop against which everything takes place, and one needs to keep a very open mind [sic], and not be too dogmatic, about how biological systems may be designed, because there is no designer [sic]. The best stimulus for this is to watch a few nature programs on TV. (Emphasis added.) 1Q&A: Kenneth E. Sawin, Current Biology, Vol 16, R268-R269, 18 April 2006. If anyone can figure out how being dogmatic about evolution is an example of open-mindedness, or how directionlessness produced cellular regulatory mechanisms, or how maintaining faith in purposelessness as a backdrop aids thinking, or how telling oneself there is no designer demonstrates things are not designed, let us know. Notice two other things he said: (1) scientists dont think too much about evolution in their day-to-day work, indicating that evolutionary theory is useless, and (2) TV is this evolutionists source of inspiration (see visualization in the Baloney Detector). So producers get their stimulus from the dogmatic claims of the evolutionary biologists, and biologists in turn get their inspiration from watching the resulting TV shows: a vicious cycle, with emphasis on vicious.Astrobiology Ten Years Later: Can It Justify Its Funding? 04/17/2006 ![]() Astrobiology just turned ten years old, but is experiencing growing pains, partly due to a starvation diet. This science without a subject (as George Gaylord Simpson quipped about its predecessor, exobiology) is struggling to justify itself at the Congressional feeding trough. Proponents tout it as the most important subject in the universe. Why, then, is Congress cutting back its rations? Astrobiology was born virtually in a day. When a NASA press conference in 1996 announced the possibility of fossil organisms in a Martian meteorite, the media fervor launched speculation into action. President Clinton appointed Vice President Al Gore to hold a space conference to discuss its implications. A preliminary astrobiology study group was formed at NASA-Ames Research Center, which became formalized as the NASA Astrobiology Institute in 1998 (see NAI Timeline). Grants were awarded to 11 research centers for research into the scientific study of life in the universe its origin, evolution, distribution, and future (see NAI). As funding for this new science continued, astrobiology websites, magazines, TV programs, conferences and projects have kept this new field in the public awareness. In a sense, this was a pragmatic move to ride a wave of public interest and centralize existing but disparate programs. Nature1 said, the field was cooked up, in part, out of political necessity, as a means of bundling together research programmes on exobiology, other life sciences and planetary science (emphasis added in all quotes). Following a late 20th century trend for scientists to collaborate in cross-disciplinary endeavors, astrobiology became an umbrella term for chemists, biologists, astronomers and physicists interested in exploring possibilities of life beyond earth. The fact that no life has been found yet is only incidental to the story. To astrobiologists, the field encompasses stellar evolution, planet formation, the search for water on other worlds, chemical evolution, hydrothermal vents, extremophiles, life detection methods, detection of extrasolar planets, and much more even the birth and eventual fate of the universe, subjects once the domain of philosophy and religion. Though SETI was specifically excluded from government funding (it continues through private sources), any research program tied into astrobiology goals, even in a peripheral way, could apply for the grant money. This year, NASA threatened to cut the $65 million astrobiology budget in half. In a nation overspent on hurricane relief and the war on terror, NASA director Michael Griffin faced hard choices. Squeezed by the cost of the International Space Station, recovery of the Shuttle program after the Columbia disaster and the pressure for a new human launch vehicle (the CEV), he distributed much of the pain to the NASA science budget, with astrobiology low on the priority list. The response was swift and strident. Scientific institutions, academics, and even private space advocacy groups like the Planetary Society and the SETI Institute joined in condemning the reductions. Tempers eased slightly when NASA restored half the projected cuts, but new astrobiology projects are likely to be unfunded. Scientists are still irate and demanding their money back. Meanwhile, some of the findings discussed at the NASA Astrobiology Conference March 26-30 in Washington, DC were not all that encouraging. The media had made a big deal about possible water on Enceladus last year. The L word (life) was usually not far behind. As reported by Richard A. Kerr in Science,2 however, the just-add-hot-water recipe may be unrealistic. George Cody warned that deep-sea hot springs couldnt have produced all of the necessary components, Kerr reported. Instead, the final assembly [sic; implies design] of molecules leading to life [sic; implies progress] must have happened somewhere between deep-sea vents, warm little ponds [an allusion to Darwin], and any number of other chemical stew pots. Cody found that, while some ingredients might be catalyzed by hydrothermal vents, the rest of the cooking had to happen elsewhere: Worst of all, important sugars and nucleobases fall apart under hydrothermal conditions. Astrobiologists are trying a new approach: think globally, act locally Submarine hot springs no doubt could have played a role in brewing the primordial soup that gave rise to life [sic], Cody said, but other environments must have contributed too. If I said it all happened in hydrothermal vents, that wont move this field ahead, he says. Thinking more globally could open up something. Perhaps the real action came along continental margins, he said. There, prebiotic compounds from deep-sea vents rose to meet drainage from the lands warm little ponds and fallout from atmospheric reactions triggered by lightning and sunlight. This is a very good [sic] approach, quite novel, says organic chemist Vera Kolb of the University of Wisconsin, Parkside. People get bogged down with the particular conditions theyre studying, but he wasnt pushing his own work.Since Europa and Enceladus were both recently advertised as targets for life detection, it may not be politically opportune at this time to mention such things to Congress. |
