Gymnastic Enzyme Acts Like Logic Gate   07/31/2004
An enzyme named vinculin undergoes “drastic” conformational changes, reports William A. Weis in the July 29 issue of Nature.1  Vinculin, with over a thousand amino acid links, is important at membrane junctions for transporting materials in and out of the cell.  It helps cellular “glue” exit the membrane so that neighboring cells can adhere to one another, such as in epithelial tissues.
    Weis reports on recent studies that show vinculin undergoes radical conformational changes during its action.  It will only build the adhesive junction when the necessary components are in place.  Nothing happens unless the participants are ready; “the binding energy of several partners is needed to overcome the thermodynamic and perhaps kinetic barriers to activation,” he says.  “Viewed in this way, vinculin functions as a logical AND gate, in which binding of two partners is required to generate an output, in this case a stable multi-protein complex”.  What’s more, this automatic regulation is essential for its function; it prevents inappropriate assembly if the amount of product is unstable.
1William A. Weis, “Cell biology: How to build a cell junction,”
Nature 430, 513 - 515 (29 July 2004); doi:10.1038/430513a.
Logic, logic gates, regulation: this is the language of intelligent design.  Each of the contacts formed during the “radical” conformational changes of this complicated enzyme is finely tuned to its substrates, and finely tuned to the concentration of ingredients in the cell.  And these finely tuned contacts are determined by the specificity of the sequence of amino acids in this protein, each coded in another language—the language of DNA.  At every step, this system only makes sense in the context of intelligent design.
    There is no suggestion in this paper how vinculin’s specificity in adhesive junctions might have evolved.  But in the latest ICR Impact article #374 (August 2004), organic chemist Dr. Charles McCombs provides very good reasons why unguided chemistry will never produce such functional complexity and specificity.  Unguided chemicals will always follow the laws of (1) chemical stability; i.e., whether the components will react at all, (2) chemical reactivity, or how fast reactants will react, and (3) chemical selectivity, or where the components react.  Working through these principles, he shows that amino acids will not join together without help, and even if they did, far more random, useless, nonfunctional polymers with damaging cross-reactions would result.  The resulting chain would always form blindly according to the relative binding energies of the amino acids.
    It takes an organic chemist careful guidance at each step to produce a functional enzyme.  “Evolutionists say that nature is blind, has no goal, and no purpose, and yet precise selection at each step is necessary,” McCombs says.  Chemicals cannot think, plan or organize themselves, he reminds us, yet Darwinians invoke a false logic that unguided processes yielded logical living systems, like this example with vinculin.  The chemist remarks, “Evolutionists just hope you don’t know chemistry!”

Darwinists Still Writing the Origin of Species    07/30/2004
A new book on the origin of species has come out.  In the July 30 issue of Science,1 Benjamin K. Blackman and Loren H. Rieseberg review Jerry Coyne and H. Allen Orr’s new book, Speciation (Sinauer, 2004, 557 pp.).  The reviewers first describe the subject matter: “The last two decades in particular have brought major advances in molecular genetics, comparative analysis, mathematical theory, and molecular phylogenetics; speciation has consequently matured from a field fraught with untestable ideas to one reaching clear, well-supported conclusions.”  Presumably some of those untestable ideas hark back to Darwin.  So in what ways does this book surpass the one penned by the master’s 1859 opus?  The reviewers outdo themselves praising the substance and style of this new book:
Jerry Coyne and Allen Orr’s Speciation provides a much-needed review of these developments.  The exceedingly well-written and persuasive text eschews speculation.  The authors instead resolutely develop testable criteria for distinguishing alternative hypotheses about evolutionary processes that may result in similar biological patterns, critically evaluate how theoretical and empirical results meet the burden of proof, and actively confront important caveats and unresolved questions with practical suggestions.  It is a testament both to the authors and to the state of the field that the book provides such a robust picture of the origin of species.
Well, this has to be good, then.  The leading definition of species is the biological species concept (BSC), that distinguishes species by the ability to interbreed.  This is not much help for systematists and paleontologists, the reviewers admit, but the book tackles what they view as the basic question of the “species problem,” which is, “why do sexually reproducing organisms fall into discrete clusters?”  Here, the debate revolves around allopatric vs. sympatric speciation (see
01/15/2003 headline).
    Coyne and Orr take the majority view that speciation is essentially synonymous with reproductive isolation: for example, two populations of squirrels might get isolated by a canyon between them, and evolve into species that can no longer interbreed.  This is called allopatric speciation.  It does not require a geographic barrier, necessarily, but differs sharply from the view of sympatric speciation, which proposes that species might diverge right within a single interbreeding population.  The book gives ear to the sympatric concept but considers most cases to be allopatric.
    So the question becomes, how do reproductive barriers arise?  And how can biologists find evidence of positive selection for traits after isolation?  This becomes the core of the book, according to the reviewers.  Related issues involve teasing out the effects of natural and sexual selection:
Speciation convincingly presents evidence for several once-unpopular theories that have returned to dominate current thinking.  Most important among these is the primacy of natural and sexual selection over drift in driving speciation.  Signatures of positive selection on genes involved in postzygotic isolation and reproductive proteins as well as experimental evidence from both the lab and field connect adaptation and sexual selection to reproductive isolation.  Another major finding is the congruence of the Dobzhansky-Muller model for the evolution of postzygotic isolation with the genetics of hybrid incompatibilities in many natural systems. In contrast, classical models of chromosomal speciation remain unpopular.  Instead, chromosomal rearrangements are now cast as facilitators, rather than causal agents, of reproductive isolation because reduced recombination within these regions restricts gene flow, thereby enabling the accumulation of selected differences and hybrid incompatibilities.
The book treats “controversial questions” reinforcement, sympatric speciation, and diploid hybrid (recombinational) speciation, although claiming evidence only occurs for the latter.  It also treats polyploidy in plants as a mechanism for speciation.  “Treatments of other plant-related topics like mating system isolation or hybridization are insightful as well, but may raise eyebrows,” but the book downplays other theories like cryptic introgression or hybrid speciation.
    Overall, the reviewers give high marks to the authors; “The book is a rich and thorough review, critique, and synthesis of recent literature that is sure to become a classic read for anyone interested in speciation.”
1Benjamin K. Blackman and Loren H. Rieseberg, “Evolution: How Species Arise,” Science, Vol 305, Issue 5684, 612-613, 30 July 2004, [DOI: 10.1126/science.1101064].
So is this the book to supersede Charlie’s, and to answer the question of how bacteria turn into humans over time?  Not likely.  Every mechanism mentioned, controversial or not, appears aimed at explaining slight variations, sometimes misleadingly called “microevolution.”  Horizontal variation is not controversial even among staunch creationists.  If evolutionists expect people to believe we evolved from slime, they need to do better than extrapolate low-level trends, and they need to show that is indeed what happened by providing the intermediates and fossils.  Talk about the origin of species if you please, but what about the origin of phyla?  (See 07/28/2004 headline).
    Phillip Johnson, a Berkeley law professor and expert in baloney detecting, put Darwin on Trial in 1991.  His book of that title put the real issue on the table:
Whether selection has ever accomplished speciation (i.e., the production of a new species) is not the point.  A biological species is simply a group capable of interbreeding.  Success at dividing a fruitfly population into two or more separate populations that cannot interbreed would not constitute evidence that a similar process could in time produce a fruitfly from a bacterium.  If breeders one day did succeed in producing a group of dogs that can reproduce with each other but not with other dogs, they would still have made only the tiniest step towards proving Darwinism’s important claims. (pp. 19-20)
As Johnson stresses in the book, it is not sufficient to base the major claims of evolution on extrapolating small changes or drawing analogies to artificial breeding.  Nor is it adequate to infer that macroevolution must have occurred because one’s philosophical preference requires it.  If the origin of species (speciation) is to be logically connected to the emergence of all living things, with all their complex organs and functions, then evolutionists must make the case that their mechanism is creative enough to add massive amounts of functional information to genes, and that the fossil record actually shows that this occurred.  Neo-Darwinism (mutation plus natural selection) fails miserably on both requirements.
    The hype in this book review is no more to be trusted than the word of the party faithful evaluating the nominee’s speech at a political convention.  Instead, the book needs an investigative reporter who understands the real controversies and can ask the hard questions.  Noticeably absent in all this backslapping was any mention of the severe weaknesses in conventional Darwinian theory that drove Stephen Jay Gould and others to propose punctuated equilibria, or the recently-deceased Francis Crick to propose directed panspermia, another group to propose niche construction (see 06/09/2004 headline), and others as recently as last week to propose other non-Darwinian mechanisms (see 07/20/2004 headline and others like 09/29/2003).  Nor was there an admission that the very fruitflies that Coyne and Orr make their life work fail to exhibit neo-Darwinian evolution (see 05/18/2004 headline).  Nor was their any mention of Coyne’s embarrassing flip flop on the peppered moth story that he long assumed was one of the best examples of speciation ever documented (see 06/25/2004), or the weakness of other examples put up in its place (see 04/18/2003 and 04/01/2004 headlines).  The only way some Darwinists can stay sane with all this controversy is to go postmodern (see 08/19/2003 headline).
    Some evolutionists have admitted evidence is lacking that numerous, successive, slight modifications can add up to big ones (see 01/15/2004, 10/14/2003 and 08/20/2003 headlines).  Coyne and Orr may dazzle some readers with case after case of reproductive isolation and microevolution, with the assumption that this bolsters the case for slime evolving into ostriches, maple trees, squid, platypus and biologists over time.  This is as unjustified as observing a cell bobbing around with Brownian motion and deciding the mechanism is capable of propelling it through the Olympic marathon.  But that’s putting it too mildly; to make the comparison more realistic (considering all the champions in the living world), better add the decathlon, weight lifting, gymnastics, archery, rowing, steeplechase, high dive, synchronized swimming, soccer, basketball, cycling....

Your Brain Learned Physics and Calculus Before You Did   07/29/2004
Tilt your head to the right while moving to the left.  The neurons in your brain just solved Newton’s equations of motion, and performed complex vector calculus equations almost instantaneously.  That’s what four neurologists Washington University of Medicine (St. Louis, MO) essentially claimed in Nature July 29,1 describing how your brain interprets the information coming from multiple sensory inputs.
    The title of their article says it: “Neurons compute internal models of the physical laws of motion.”  The article is filled with equations that the neurons have to solve correctly to help you determine whether the motion you feel means you are moving left or right, tilting, or a combination of the two.  The signals come from the otoliths in your inner ear (see
10/10/2003 headline) and from the fluid in the semicircular canals.  What if these inputs give contradictory information?  The net vectors of the inputs could cancel each other out, or sum up to give a wrong impression.  The scientists mapped out the equations that would have to be solved to distinguish between the components of translational and gravitational motion, regardless of phase, and then experimented on monkeys while watching the activity of the brain.  They found that the way neurons fire in response to the stimuli match predictions of how the information would have to be parsed to fit the terms of the equation.  In conclusion, they state:
These results illustrate a direct correlation between cell firing rates and the equations of motion, as applied to movement in a gravitational environment and the physics of the external world.  A neural basis for an internal model representation of the relationship between the physical environment and either the sensory detectors or the motor apparatus has only recently begun to be explored.  Here we have shown evidence that, in support of theoretical predictions, subcortical neural populations might provide a distributed solution to the inertial motion detection problem.

1Angelaki, Shaikh, Green and Dickman, “Neurons compute internal models of the physical laws of motion,” Nature 430, 560 - 564 (29 July 2004); doi:10.1038/nature02754.
As expected, this paper makes no attempt to explain how such a system could have evolved.  The more detail provided in a research paper about the workings of a biological system, the less apt are the authors to attribute it to time and chance.
    One of the defining marks of life is awareness of the surroundings and ability to respond to the environment.  Think about all the components required to make this work: you need sensors, they need to be able to communicate to the central processor, and the central processor has to be able to interpret all the multiple inputs that provide sometimes contradictory information.  So not only are the cells themselves irreducibly complex, the organs and processors are also irreducibly complex, or else no equations of motion can be solved.  In fact, look at each irreducibly complex component of this system, and you will find additional irreducibly complex parts within them, every one vital to the success of the whole project.  Who taught your neurons the equations of physical motion and the techniques of vector calculus?  Playing a game of tennis requires rapidly solving a continuous stream of computational problems (see 01/05/2001 headline).  Don’t get cocky about this skill; owls excel at math, too (see 04/13/2001 headline), and even your dog knows calculus (see 05/20/2003 headline).

Solar Systems Defy Theories   07/29/2004
Stuart Ross Taylor (Australian National University, Canberra) feels left behind.  The astronomers have their nice, neat H-R diagrams to explain stars, but no such diagram exists for planetary scientists.  Our hodgepodge collection of planets, moons and small bodies defies classification, to say nothing of the extrasolar planets that have been discovered so far, mostly in wild elliptical orbits or close-in to the parent stars.  Writing in the July 29 issue of Nature,1 he compares stellar and planetary astronomy:
By contrast, planets are individuals that show few systematic relationships and have resisted attempts at classification or even definition, as witnessed in the furore over the status of Pluto, which is an eccentric dwarf when placed among the planets, but is better suited to be the king of the many icy bodies in the Kuiper belt.  So far, there is no planetary equivalent of the Hertzsprung-Russell diagram.  Even if we arrive at a satisfactory explanation for the formation and evolution of our planetary system, there is no guarantee that this will apply elsewhere.  Perhaps this is the reason, as Stephen Brush has commented, that the origin of the Solar System represents one of the oldest unsolved problems in science.
Taylor says this in spite of mentioning in the first paragraph that Laplace in 1796 had explained the planets as condensing from a solar nebula.  As an example of the difficulties in explaining the origin of planets, he points to the long history of trying to explain Earth, from Hutton (1788) to plate tectonics.  But even today’s theory of plate tectonics may be too specialized to apply anywhere else:
But this process is unique to the Earth among the planets of the Solar System and was only made possible by the late stochastic addition of a water content of a few hundred parts per million.  Many of the difficulties in trying to understand the evolution of the Moon arose from the uncritical attempts to apply our hard-won experience with wetter terrestrial rocks to those from our bone-dry satellite.
Another example of the difficulty is comparing Venus and Earth.  They should be twins, but “the Earth resembles Venus much as Dr Jekyll resembled Mr Hyde.”  What causes the difference between these twins?  “The short answer is water,” he gives as if a rote answer out of the textbook, but “As we search for terrestrial-like planets elsewhere, we need to find out the reasons for these differences and the conditions that allow these diverse bodies to form at all.”  That can only come from a new interdisciplinary approach, a distinct new mindset “somewhere between the approaches of astronomers – who want to treat planets mathematically like stars – and geologists, who want to generalize from their detective-like experience with the Earth.”
1Stuart Ross Taylor, “Why can’t planets be like stars?”
Nature 430, 509 (29 July 2004); doi:10.1038/430509a.
The fact that Taylor raises these questions means that the typical rote answers given simplistically in textbooks are wrong.  He sounds like astronomers are at square one explaining the planets, despite 208 years since Laplace famously remarked, when asked where God fit into his model, “I have no need of that hypothesis.”  Well, put up or shut up.  We’re still waiting.  We know a lot of things now that Laplace did not, and the trend of recent discoveries has been contrary to the expectations of nebular and planetesimal theorists, so much so that Hal Levison called his own theory a fairy tale, and others crazy (see 05/30/2002 headline).  His subsequent suggestion was the only wise thing he said: “We have to start thinking of alternatives.  Probably there’s a method for their formation that no one has even thought of yet.”  Well, some have, but their views are categorically disallowed by the reigning naturalistic paradigm.
    We hate to break it to Taylor, but the stellar astronomers don’t have everything so neatly tied up as he supposes, either (see 07/08/2004 headline).  In fact, does any naturalist have anything neatly tied up? (See next two headlines.)

Cambrian Explosion Explained, or Explained Away?   07/29/2004
James Valentine, an authority on early fossils, has just published a new 600-page book on the Cambrian explosion with the Darwinesque title, On the Origin of Phyla (U. of Chicago Press, 2004).  Stefan Bengtson (Swedish Museum of Natural History) reviewed it in the July 29 issue of Nature.1  He points out that “Darwin wisely called his best-known work On The Origin of Species; the origin of phyla is an even stickier problem, and Valentine deserves credit for tackling it at such breadth.”.  He is not sure, however, that Valentine succeeded in explaining “one of the most significant revolutions in the history of life, the Cambrian explosion.”
    One complaint is that in all those pages Valentine said little about the ecology or physical environment in which the “explosion of body plans” took place.  Also, Bengtson is not convinced that the usual explanation is meaningful that a phylum is simply a clade (category) of all animals that diverged from a common ancestor when two body plans diverged in the remote past; “This avoids the question of how body plans arise and whether there may be others not represented by living forms,” he chides.  Worse, Valentine fell into a logical trap, he feels:
Defining a body plan isn’t easy, however.  Valentine’s definition, for example, is dangerously circular: “an assemblage of morphological features shared among members of a phylum-level group”.  What does that mean, except that when we define a phylum we also define its body plan, or vice versa?  Valentine proposes to define the origin of a phylum by the acquisition of a key apomorphy – a unique derived trait.  This may be more subjective and less convenient than letting the total (stem and crown) group or the crown group define the phylum, but it gives due priority to biological significance over methodological convenience.  After all, we want to know how different kinds of organism evolve by natural selection, and how they interact with each other and with the environment.  They do that with their phenotypes, not their pedigrees.
Bengtson also considers the suggestion that body plans represented “more or less the total number of possible solutions to the problem of being an animal, or whether there were numerous other possibilities that came into being but became extinct because of bad luck or bad design.”  (The evidence shows a decrease in body plans after the explosion due to extinction, not a gradual rise in diversity.)  But is this just explaining away the evidence?
The pattern of diminishing evolutionary novelty subsequent to this event, he says, may have been due less to developmental constraints than to a saturation effect (candidates for new adaptive radiations were already available among existing body plans).  He also believes that the Cambrian explosion produced a lot more homoplasies (similar characters with independent origins) than most phylogenetic analyses suggest – in my view an extremely important point that calls for much more careful character evaluation than is commonly done.  He is clearly not impressed, then, by some recent attempts to use fossils to bridge gaps between phyla.
If the reader is left wondering how the body plans arose in the first place, the final paragraph of this book review may not be all that satisfying.  How could environmental changes generate the information necessary to produce fins, eyes, jointed limbs, propulsion mechanisms, and so much more that is evidenced in the Cambrian fossils?
Valentine seems most happy with intrinsic biological mechanisms for the rapid appearance of phyla.  Large parts of the book deal with developmental prerequisites (such as cell-type numbers and gene regulation) for the event.  Ecological interactions, such as predation, are given more cursory treatment.  As for the physical environment, he merely concludes, somewhat apologetically, that although physical environmental factors were “supremely important”, he does not see any evidence that extraordinary environmental events were causally connected with the Cambrian explosion.  Given that extraordinary environmental events did indeed occur shortly before the explosion, I would give the jury just a little more time to ponder the question.  But first I would make sure they had read this magnificent book.
So how did the body plans arise in a geological blink of an eye?  This question was apparently not on the agenda.
    Next day in Science,2 R. Andrew Cameron also reviewed Valentine’s book.  This review praised and criticized different things.  Cameron first dismisses the analogy “explosion,” primarily because he claims that molecular studies put the origin of the phyla farther back into the precambrian; consequently, he claims, it was “neither an explosion nor did it happen in the Cambrian,” although he does agree that the Chengjian fossils display “representatives of almost all major groups of animals” (see 07/20/2004 headline).  He mentions the possibility that ancestors were soft-bodied and small, resulting in a poor fossil record; “Perhaps the conditions of the Cambrian environment allowed the rapid appearance of hard skeletal parts, greatly favored fossilization, or both.”  But then he mentions the discovery of “fossil pre-Cambrian embryos from the Doushantuo Formation of southwest China, estimated to be 40 to 55 million years older than the base of the Cambrian,” so being soft and small did not hinder these specimens from becoming fossilized.
    Cameron understands the problem of the Cambrian explosion, and claims it is more of a problem now than in Darwin’s day:
The question of when and how higher taxonomic groups like phyla evolved differs markedly from the one Darwin addressed 145 years ago in The Origin of Species.  It is not simply different in scale but also in quality.  Although it is somewhat easier to see how changes in single genes can lead to differences among species that render some more capable of surviving in particular environments, it is more difficult to account for the many changes that lead to entirely different bodyplans as a simple accumulation of single-gene effects.  For example, marine stickleback fishes possess bony plates and spines that presumably prevent predation, while their freshwater relatives show a loss of this armor through changes that can be attributed to a single gene [see 06/18/2004 headline].  However, entire organ systems or embryonic germ layers, features that distinguish higher taxa, can be explained in terms of the gene regulatory networks whose architecture is hardwired into the genome.
So the question for the origin of phyla is how did these hardwired gene regulatory networks arise?  Cameron claims that Valentine “does not incorporate a molecular model in his final synthesis,” so he offers one himself: major changes might arise through changes in regulatory genes like transcription factors.  Can he give us an example?  “For instance, a morphogenetic program may evolve with relatively minimal changes to establish a new spatial domain of expression for a cell-differentiation program, and the resultant animal has a new body part.”  He does not elaborate.
    Cameron praises the first two sections of the book that discuss the origins of the phyla, descriptions of the phyla, and the fossil record.  The third section grapples with the evolution of the phyla.  This section is lacking, the reviewer thinks: “The pictures he delineates here reveal correlations uniting different levels of biological organization, but absent are firm statements about causal mechanisms from which predictions could be made.
    Cameron leaves us with one more concern.  “In view of the volatility of the ideas and the controversy that still exist in this particular area of evolutionary biology, one might argue that it is too early to explain the causes of the origin of phyla.  But as Valentine aptly points out, the time will never be exactly right: there are always more information to incorporate and more ideas to organize.”
    Incidentally, Nature also reported discovery of an arthropod fossil that pushes its group, the Euthycarcinoids, back 50 million years into the Cambrian.  “Despite its antiquity and marine occurrence,” they admit with surprise, “the Cambrian species demonstrates that morphological details were conserved in the transition to fresh water.”

Satisfied?  Apparently in 600 pages, Valentine did not answer the most basic and fundamental question, how did all this biological complexity emerge in a short time?  Pounding the earth with meteors and tidal waves and volcanoes won’t do it.  Invoking a new predator won’t create an elaborate escape mechanism in the prey; it might just mean the predator will eat everything and then starve.  Cameron’s folklore is simplistic: a regulatory gene mutates and presto!  A new body part!  Can duplicating some protuberance generate an eye?  Come on.
    Let’s parse Cameron’s carefully-worded closing lines.  He said, “In view of the volatility of the ideas and the controversy that still exist in this particular area of evolutionary biology, one might argue that it is too early to explain the causes of the origin of phyla.”  Cameron, like Valentine is well aware of the pounding the Darwin Party is getting from the Intelligent Design Movement with the Cambrian Explosion hammer (see The Cambrian Explosion: Biology’s Big Bang by Meyer, Ross, Nelson and Chien (12/01/2003) available online at the Discovery Institute).  The Cambrian Explosion is only controversial because the Darwinians have no answer, and the creationists and ID proponents know it.  So he’s worried that Valentine’s new book is going to provide even more ammo to the enemy.  His coded message to the Darwin Party can be translated, “What do you think you are doing, Jim, letting the creationists know we’re up a creek?  Better to say nothing than to advertise our weaknesses!”
    Does anyone see in either of these reviews any real, logical explanation for the explosive appearance of trilobites, worms, jellyfish, corals, and vertebrates, with any evidence to back it up?  Each of these organisms is composed of irreducibly complex cells, and organs made up of irreducibly complex parts.  When they first appear in the fossil record, they are already fully formed and operating.  If the world’s expert can’t explain this after 30 years of thinking about it, then maybe there isn’t an explanation – from a Darwinian viewpoint.  This requires some fresh blood from thinkers not wedded to a dying, outmoded, falsified model that is on the verge of extinction.  Any takers?

Spaghetti in a Basketball: How the Cell Packs DNA for Controlled Access   07/28/2004
The beginning sentence of an article in Current Biology1 can’t help but grab your attention:
Imagine trying to stuff about 10,000 miles of spaghetti inside a basketball.  Then, if that was not difficult enough, attempt to find a unique one inch segment of pasta from the middle of this mess, or try to duplicate, untangle and separate individual strings to opposite ends.  This simple analogy illustrates some of the daunting tasks associated with the transcription, repair and replication of the nearly 2 meters of DNA that is packaged into the confines of a tiny eukaryotic nucleus.  The solution to each of these problems lies in the assembly of the eukaryotic genome into chromatin, a structural polymer that not only solves the basic packaging problem, but also provides a dynamic platform that controls all DNA-mediated processes within the nucleus.
The article by Craig L. Peterson and Marc-André Laniel is otherwise boringly titled “Histones and histone modifications,” but after this appetizing start, goes into detail about how the tangled mess of alphabetized pasta is exquisitely controlled, folded, unfolded and copied continuously inside the cell, with the help of numerous protein and RNA parts.
    Of special importance are the histone proteins that comprise chromatin.  Scientists have been discovering for several years now that these histones have “tails” of amino acids that can be altered through numerous ways.  These alterations, called “post-translational modifications,” seem to influence the DNA wrapped around them in many important ways.  They signal genes to activate for transcription, places needing DNA repair, places to start or repress DNA elongation or replication, where to silence telomeres, places to deposit more chromatin, and more.  A table in the article lists 95 histone modifications and their functions that are known so far.  Some are involved in mitosis (cell division), spermatogenesis, X-chromosome inactivation (silencing one of the two X-chromosomes in the female), apoptosis (programmed cell death), DNA “memory” and other important cell processes.  Some have said these modifications constitute a “histone code” (see “Cell memory borders on the miraculous,”
11/04/2002 headline).  These authors term it differently, but no less amazing: “rather than a histone code there are instead clear patterns of histone marks that can be differentially interpreted by cellular factors, depending on the gene being studied and the cellular context.”  Activities like DNA repair or replication are often accompanied by histone modifications, for instance, as if one enzyme leaves its mark on a histone to signal a follow-up function.  Complexes of small RNAs and enzymes depend on these markers to know where to go and what to do; the histone tails serve as attachment points for specific enzymes.  And if that is were not amazing enough, the interplay of neighboring histone markers, or cross-talk, can have “a profound effect on enzyme activity.”   The authors explain, “Thus, in many ways histone tails can be viewed as complex protein-protein interaction surfaces that are regulated by numerous post-translational modifications.  Furthermore, it is clear that the overall constellation of proteins bound to each tail plays a primary role in dictating the biological functions of that chromatin domain.”  Finally, since some of these histone states can survive cell division, they augment what’s inherited beyond DNA alone.  The authors provide no suggestions on how this system might have evolved.
    On a related subject, three geneticists from Scotland describe, in the same issue of Current Biology,2 how DNA packs itself so tightly and efficiently.  There are specialized proteins called condensins that perform this job.  They are members of a set of hairpin-shaped enzymes called “structural maintenance of chromosomes” enzymes (SMCs, see 08/07/2002 headline).  The authors remind us that “These extraordinary molecules are conserved [i.e., unevolved] from bacteria to humans.”  Scientists are beginning to be able to watch condensin do its amazing work in real time (see “DNA folds with molecular velcro,” 06/07/2004 headline).  Condensin produces “supercoils” of DNA, one of many steps in packing the delicate DNA strands into a hierarchy of coils that results in a densely-packed chromosome.  “It is not entirely clear how the DNA is held in this supercoiled state,” they say, “but several studies suggest that the V-shaped arms of the condensin complex may loop and clamp the DNA in place.”  This clamping is “rapid and reversible.”  Scientists watching the process in both bacteria and humans are “showing that both vertebrate and bacterial condensins drive DNA compaction in an ATP-dependent fashion with a surprising level of co-operativity that was not fully appreciated.”  The condensin molecules work as a team; if not enough condensin is around, nothing happens.
    These authors point out also that condensin is just one of many enzymes involved in chromosome formation.  Think about how remarkable it is that during each cell division, the chromosomes are structured so reliably that they can be labeled and numbered under the microscope.  “Our own proteomic analysis,” they claim, “has identified over 350 chromosome-associated proteins, so there is clearly more work to be done.”  There is no mention of evolution in this article, either.

The views we are getting of a cell since the invention of the microscope can be likened to those from a UFO descending from earth orbit to ground level.  From orbit, a city like Boston seems to have a lot of structure and organization.  As we descend into this alien world, more and more organization becomes apparent, till from airline height, we see complex transportation arteries and machinery apparently all coordinated and purposeful.  From helicopter height, individual workers begin to come into focus.  We are now approaching ground level, and able to watch factory workers and figure out what it is they are doing.  Just imagine what Leeuwenhoek would think, considering he only got the orbital view.
    It’s not getting any easier for the Darwin Party.  If the mental picture of 10,000 miles of spaghetti in a basketball didn’t grab you, considering it is efficiently packaged with each inch of pasta accessible and reproducible, then maybe you just hate Italian food or sports and need a more suitable analogy.  Breathes there a man with soul so dead who never to himself hath said, This is my own, my Creator’s hand?  Yes, sadly, there is; read next headline.

In the Last Days There Shall Be Scoffers   07/28/2004
Current Biology this week contains two entries either attacking creationism or exalting Charles Darwin.1,2  Nigel Williams reports on the 100th birthday of Ernst Mayr (see
07/02/2004 headline), and his “tireless campaign against creationism”:
Ernst Mayr, the renowned evolutionary biologist and champion of Darwin, celebrated his 100th birthday earlier this month by leading a scathing attack on creationism.  The evolutionary biologist, acclaimed as one of the most prolific researchers, has no intention of retiring and is shortly to publish new research that dismantles the fashionable creationist doctrine of ‘intelligent design’.
Apparently Mayr’s approach is nothing new to anyone in the I.D. community who has read On the Origin of Species; Williams says that “‘intelligent design’ – the latest way in which creationists have sought to present a divine origin of the world – was thoroughly rebutted by Charles Darwin a century and a half ago.”  What’s motivating Mayr’s campaign?  “a sense of exasperation at the re-emergence of creationism in the US,” Williams says.  Evolution was no problem in Mayr’s childhood schools in Germany, so why are so many school boards trying to water it down or omit it in America?  Williams recounts the case in Georgia when the superintendent of schools tried to have the “controversial buzzword” evolution “banned” from the curriculum.  “Fierce protest, including criticism from Jimmy Carter, the former president, reversed this,” Williams states with apparent satisfaction.
    In its ongoing series of interviews with practicing scientists, Current Biology interviewed mathematics professor (U. of Vienna) Karl Sigmund (also a popularizer of evolutionary game theory: see 02/10/2004 headline).  Here is his answer to the question, “What turned you on to biology in the first place?”
I hit upon a German version of Darwin’s ‘Descent of Man’ at the tender age of twelve.  I cannot possibly have understood much of it, but was immediately fascinated, first by a photo of old Darwin, whose piercing eyes haunted me, and then by the idea of having apes among my forebears: it explained why I felt so happy in the tree-tops.  Besides, I liked the fact that not a few of my elder family members – catholics all – were distressed to see the book in my hands.  Much later, I noticed that a thoughtful editor had removed the parts on sexual selection.  What would my relatives have said to that!
After Sigmund was turned off by biology in school and became fascinated with mathematics, there was another turning point:
I forgot all about biology and became a professor of mathematics before I came across ‘The Selfish Gene’.  That was a turning point for me.  [Richard] Dawkins’ very first sentence thrilled me: “This book should be read almost as though it were science fiction.”  There were not just facts in biology; there was a place for the ‘what if’ a basic question for any mathematician.
Sigmund is asked about remaining challenges to evolutionary game theory, and admits it needs to be tied in with the biology and neurology of the brain, “how modules in the brain interact, and cooperate, in guiding an individuals’ feelings and wishes.”  He points to tentative experiments that look for relationships between brain imaging and human reactions to perceived fair and unfair situations.  “Such a form of neuro-economics – or, better, physio-economics, because hormone levels play a great role too – may eventually tell us more about human nature than anything since Darwin studied expressions of emotions in man and animals.  And if I feel foolish when I re-read this sentence ten years from now, I will tell myself that it was pretty good science fiction.
1Nigel Williams, “One long argument,” Current Biology, Volume 14, Issue 14, 27 July 2004, Page R540, doi:10.1016/j.cub.2004.07.002.
2“Q&A: Karl Sigmund,”
Current Biology, Volume 14, Issue 14, 27 July 2004, Page R541, doi:10.1016/j.cub.2004.07.003.
One way for Karl Sigmund to feel foolish real fast is to read Creation-Evolution Headlines regularly and other publications outside the Darwin Party propaganda machine (here’s a list for starters).  An easier way is to flip a few pages in the same issue of Current Biology to the articles on histones and condensins (see headline above).  That’s if Sigmund is even interested in truth over “science fiction”.  He said it himself: he was drawn to evolution not by a studied analysis of the facts, but by (1) the haunting eyes of Charlie, the materialist’s buddha, (2) a fallacious, childish non-sequitur that apes in the family tree made him feel at home climbing trees, and (3) childish rebellion.  Parents, beware.  If your kid can’t think straight or exercise self-control by the age of 12, it may be too late.  The kid will be a sucker for the Darwin Party storytelling circus.
    Ernst Mayr is on his last crusade before becoming a creationist.  (For those at the Darwin National Convention, that means meeting your Maker.)  Solomon said, in a paradoxical quatrain, to “answer not a fool according to his folly,” but rather, to “answer a fool according to his folly” (Proverbs 26:4-5*).  This is not a contradiction.  Answer not a fool according to his folly, “lest you be like him,”; i.e., don’t imitate his style of argument and get into a vituperative shouting match with irrelevant and useless trivia.  Rather, answer a fool according to his folly “lest he be wise in his own eyes”; i.e., don’t let him get away with baloney, or let others who hear him be swayed by it.  For instance, in biology class, your fellow students should not hear the evolutionary mythmaking of the teacher go uncontested.  Suggested response: keep holding up the facts and asking logical questions.  Teach Mayr and Sigmund about histones and condensins and diatoms and plant seeds and motorized sunscreens and migrating sparrows and cellular roller coasters and spider superpowers and underground pioneers and whale aeronautics and antennas built with motorized trucks and 300 million neurons required to see a picture and a million other things.  Ask them, “How could such things evolve without plan or purpose?  No, I mean really—not just a story, but really now.  And if it happened, where is the evidence?” (see 07/22/2004 headline)  Keep up the pressure, gently and persistently.  These things take time.  After sufficient exposure to the observations, if they continue to sputter nonsense, there is nothing more you can do except to try to prevent folly from becoming established as the official, uncontested curriculum for young, impressionable minds not yet able to discern their right hand from their left.

Solar System Update   07/27/2004
What’s happening at Mars and Saturn?  In this golden age of planetary science, the extraordinary has become commonplace.  Let’s check in and see what the spacecraft have found lately.
Mars.  The
Mars Exploration Rovers Spirit and Opportunity are still going strong, well past their nominal mission.  Despite a few minor problems (and decreasing sunlight as winter sets in), they both are in exciting locations that are giving the scientists new thrills.  The latest major announcement (see New Scientist) is that water not only appears to have existed in the past, but persisted for some time.  Spirit is now climbing the Columbia Hills in Gusev Crater, while Opportunity a hemisphere away is tantalizing scientists with geological layers in the crater named Endurance.  The MER website now posts interesting slide shows of each week’s activities so that earthlings can follow the adventures.
    Fascination with rovers should not make us forget the three Mars orbiters that continue to send back more fascinating imagery than a human mind can process.  The venerable Mars Global Surveyor posts its latest images here, and the stalwart 2001 Mars Odyssey, well past its 10,000th orbit, posts its latest infrared images here.  Not to be outdone, the European Mars Express continues to churn out high-resolution, color stereo images from orbit, including this latest shot of a fractured crater near Vallis Marineris.
Saturn.  Since its arrival at Saturn July 1, Cassini is healthy on its first long, elliptical orbit.  Though the next close encounter isn’t till October 26, when it flies past Titan at only 750 miles, the spacecraft is not idle.  New images of the moons Mimas, Enceladus, Iapetus, Tethys, Dione and Rhea have trickled in, though not as yet better than Voyager’s 1981 images because of the distance.  Much, much better ones are in the mission plan.  The nicest color image recently was this color composite of the rings.  At full resolution it would make nice wallpaper.  The Huygens Probe operations team had a successful risk review and probe checkout in preparation for their nail-biting January 14 parachuted descent to the surface of Titan.  Meanwhile, the instrument teams (magnetometer, plasma wave, cosmic dust, ultraviolet and infrared, radio science and, of course, visible light imaging) are all busily taking data about Saturn’s winds and magnetic field, rings, moons and space environment.  Some of it is surprising and should be announced soon.  Note: NASA headquarters maintains its own Cassini website.
Mercury.  A new mission to Mercury named MESSENGER – the first since Mariner 10 in 1975 – is due to launch next month, August 2.  The mission designed by Johns Hopkins Applied Physics Laboratory will take a long time to get results, though; the complex gravity-assist trajectory requires seven years before orbit insertion in 2011.  Only about half of the planet was seen by Mariner 10 so there is a great deal more to learn about the innermost planet.
Earth.  Other planets are interesting, but we have to (better, get to) live on this one.  The AURA mission just launched successfully on July 15 to study the upper atmosphere, especially the dynamics of the ozone layer that protects us from dangerous ultraviolet radiation.
Interpreting this wealth of data from these exotic places will take years, but the new observations are certain to help answer old questions while stimulating new ones.  Meanwhile, we need to keep the Darwin Party in line.  Help your local Darwinist break his or her bad habit of equating water with life, a non-sequitur if there ever was one (e.g., from New Scientist, “The actual time span has not been estimated, but it reveals enough time to strengthen the possibilities that life could have evolved on Mars.”)  A worse habit is thinking the discovery of life in space means the death of God.  Apparently, they do not understand just how big God is; some creationists think life might be found on Mars or beyond.  And who knows?  Maybe the first incoming SETI message will be John 3:16 in Vulcan.  For now, don’t let the Darwinese hype bother you.  Raw data belongs to everyone.  Just because a fat spectator is belching hot air and making himself a nuisance doesn’t mean you can’t enjoy the game.

Modern Cosmology Goes Schizophrenic    07/27/2004
According to Charles Seife writing in Science,1 more cosmologists are taking parallel universes seriously.  This is a consequence of the Many Worlds interpretation of quantum mechanics, one possible mathematical solution to the effects of quantum “weirdness.”  If you think our headline is too harsh, read Seife’s opening in a Rod Serling voice while playing the Twilight Zone theme in the background:
As is your habit, you are reading Science at breakfast (today’s treat: an omelet made with dodo eggs). But as soon as you finish this paragraph, a carnivorous wombat crashes through the door into your apartment and chomps angrily on your prehensile tail.  Right ... now.
    Ridiculous?  Certainly—here.  But it’s true somewhere in the universe, according to many scientists.  An increasing number of mainstream physicists have espoused an almost unspeakably bizarre picture of the cosmos, one filled with mirror worlds and parallel universes, with doppelgängers and alternate histories.  In many of these parallel universes—countless ones—an exact duplicate of you is doing exactly what you’re doing: reading this article in Science magazine.  In others, you exist with subtle (and not-so- subtle) changes from your present-day life—you sport horns or speak in Latin or make a living by juggling hedgehogs at cocktail parties.
No further questions, your honor.
1Charles Seife, “Physics Enters the Twilight Zone,”
Science, Vol 305, Issue 5683, 464-466, 23 July 2004, [DOI: 10.1126/science.305.5683.464].
Seife’s paragraph subtitles are twists on explicit religious phrases: Reasons to believe, You’ll never walk alone, Worlds without end.  (Question: why do you think he used the name of Hugh Ross’s organization here?)  Seife gives air to critics of the Many Worlds hypothesis, but he does not attack the idea as stupid.  Instead, he gives pretty good press to its advocates.  Undoubtedly if Richard Dawkins were reading this issue sitting on his prehensile tail, he would nod approvingly, while calling creationism ignorant, stupid, insane or wicked.
    If even in your wildest dreams you granted a nanometer of credibility to such claims, you would still have to ask what caused a universe of universes to have the properties such that the laws of quantum mechanics would give rise to a world like ours.  Anything that begins to exist must have a cause.  The universe began to exist, therefore the universe had a cause.  Q.E.D.
    Fantasyland was fun, but time to escape to reality and enjoy Adventureland.  There’s no boredom in the real world, and the equations have a way of working out in practical ways.

How Cells Build Hard Parts    07/26/2004
You have rocks in your head, and it’s a good thing, or you would die of starvation and imbalance.  Living things have need of inorganic structures for various functions.  Can you name the mineral structures in your body?  The answer is: bone, dentin, enamel and otoliths.  The last three are specific to your head.  Dentin and enamel help us chew our food, and otoliths help us know which way is up (see
10/10/2003 headline).  Vertebrates have bones and teeth, birds lay eggshells of calcium carbonate, and many marine and terrestrial animals build mineral shells.  Scientists and engineers are drawn to the skill organisms exhibit in the construction of hard parts (called biomineralization), and they want to imitate it.  We’ve drawn attention to the amazing capabilities of the conch shell (see 06/26/2003 headline) and diatoms (see 07/21/2004 headline).  Two recent articles in science journals discuss the human fascination with biomineralization.
    A book review in Science last week1 opens with praise for the lowly diatom:
The abilities to design and construct inorganic materials with specified atomic structure, size, shape, orientation, and number of defects and to integrate these architectures into functioning devices form the foundation for advances in technologies that rely on the devices’ electrical, optical, magnetic, and chemical outputs.  However, assembly methods that allow simultaneous control of these features at lengths from the nanometer scale to the macroscale continue to elude scientists and engineers....
    What if there were constructors that could sequester inorganic ions from water, accumulate and concentrate them to produce architectures controlled over length scales from nanometers to tens of centimeters, and do all of this in a matter of hours at ambient temperatures?  Such constructors are not inventions of science fiction novels but rather single-cell plants called diatoms.... Biomineralization processes can form structures that are the envy of all of us who strive to understand molecular mechanisms of the assembly of inorganic materials.
The book Mark E. Davis is reviewing is Biomineralization by the Mineralogical Society of America and Geochemical Society, 2003.  He was especially impressed by the complexity of the molecular mechanisms organisms use to build their hard parts, mechanisms that show mastery of molecular biology, protein chemistry, nucleation thermodynamics, and crystal growth.  Some organisms build minerals inside cells, outside cells, or between cells.  Davis found one example particularly attractive to the materials scientist:
Nacre, the mother-of-pearl layer found on the inner surface of shells, has a fracture toughness approximately 3000 times that of the synthetic analogue aragonite (calcium carbonate).  Nacre is composed of thin (circa 30 nm) layers of a protein-polysaccharide intercalated between 0.5 micrometer-thick layers of aragonite tablets.  The weak interface between the organic and inorganic layers is thought to dissipate the energy of crack propagation and thus strengthen the composite structure. This sophisticated architecture provides clues as to how man-made structures could be improved.
How could such capabilities evolve?  “The evolution of mineralized tissues has been enigmatic for more than a century,” says a team of three Penn State scientists writing in PNAS2 on the subject.  Feeling that comparative genetics could help solve the enigma, they undertook a search for homologous genes and proteins between disparate groups.  “Mineralized tissue is a critical innovation in vertebrate evolution,” they begin, “offering the basis for various adaptive phenotypes: body armor for protection, teeth for predation, and endoskeleton for locomotion.”  Certain “primitive” fish have dentin-like body armor covered with an enameloid substance that the team believes evolved into fish scales.  Their previous work suggested that mammalian teeth and agnathan body armor are homologous.  This time, they examined the genome of a teleost fish and failed to find any homologous proteins for mammalian tooth enamel.  Though dentin in teeth seems homologous with body armor that formed on skin collagen of fish, their analyses “suggest that mammalian enamel is distinct from fish enameloid.”  Instead, they believe “Their similar nature as a hard structural overlay on exoskeleton and teeth is because of convergent evolution.”

2Kawasaki, Suzuki and Weiss, “Genetic basis for the evolution of vertebrate mineralized tissue,” Proceedings of the National Academy of Sciences USA, 10.1073/pnas.0404279101, published online July 22, 2004.
These two articles illustrate the disparity between hard science and soft, mushy, slippery Darwinian scientism.  It goes like this: (1) The organism excels at an engineering feat.  (2) It must have evolved, but we don’t know how.  To the extent the organism elicits admiration, the Darwinian explanation elicits disgust. 
  The PNAS article is a useless hodgepodge of storytelling, attempting to force uncooperative facts into a predetermined plot.  In one place, they “calibrate” their Darwinian tree based on Darwinian assumptions.  When that produces anomalous results in another part of the tree, they simply adjust the rate of evolution on that branch.  When another branch has trouble, they rearrange the branches and invoke the magic trick of “convergent evolution” to explain similarities that did not appear to have a common ancestor.  All through, there are wiggle words like must have, might have, quite possible, suggests, possible, co-opted, although there is no direct fossil evidence to date... may not have, probably, assumed to etc.  The data are only secondary props in this tweakfest to keep Charlie as the national idol.  Do they ever explain how multiple genes produced multiple proteins by accident that work biomineralization wonders?  No; it is all an exercise in reassuring the reader that the Darwin Party is not really lost.  For baloney detectors who are not intimidated by the bluffing of technical jargon or prestigious journals, it makes no sense.  Try this howler for fun:
Together these facts make it likely that the developmental mechanism of mammalian tissue mineralization was elaborated during bony fish evolution in actinopterygians or sarcopterygians.  Although the genetic tools of tissue mineralization are totally unknown for chondrichthyans, it is quite possible that they have developed their own tools through independent gene duplications and functional selection histories.
What a total whitewash; do you see what they did?  They just swept a huge problem under the rug.  When the data were missing or contrary, they ascribed it to evolution anyway.  They personified fish, turning them into materials engineers and tool inventors.  And that ending phrase, “independent ... functional selection histories,” should be framed as a classic euphemism for Darwinian dogma.

Evolutionists Consider Non-Darwinian Mechanisms    07/23/2004
According to classical Darwinian evolutionary theory, variations in the germ lines produce phenotypic changes that, on rare occasions, prove beneficial to an individual, and cause an organism to outcompete its peers in the struggle for existence.  The hypothesis of Natural selection claims that the individual with a slightly beneficial variation, being more “fit,” leaves more offspring.  Darwinian changes are gradual, random and independent.  No sudden leaps (saltations) are allowed, and changes do not “conspire” toward a goal (i.e., no “orthogenesis” or straight-line evolution).  Natural selection acts on genes in the individual (individual selection).  Speciation occurs when a population becomes geographically isolated from another population (allopatric speciation) and the accumulated changes no longer permit interbreeding.  Darwinians believe this gradualistic process is sufficient to account for all the innovations in all living things since the first cell emerged on Earth: all the organs, functions and behaviors of birds, insects, fish, plants and man.  Darwin did propose an additional mechanism, sexual selection, in The Descent of Man.  Ever since On the Origin of Species by Natural Selection was printed, however, competitors have proposed other mechanisms for evolution: group selection, kin selection, sympatric speciation, various Lamarckian mechanisms (inheritance of acquired characteristics), niche construction, Gaia, and more.  The debates still go on today.  Two recent papers offer “new” non-Darwinian mechanisms that might supplement the process of natural selection.
    According to
EurekAlert, scientists at the Universitat Autonoma de Barcelona have discovered a “New genetic mechanism for evolution.”  In their view, transposable elements (transposons) in the genes can generate antisense messenger RNA (mRNA) in neighboring genes that can silence or otherwise alter the expression of the genes.  “For a long time they [i.e., transposons] have been considered as a useless part of genetic material, DNA left overs,” the press release states.  “However, it is more and more clear that transposons can cause favourable changes for the adaptation and survival of the organism.”  The press release does not provide any evidence of an innovative change due to this mechanism, but they point to an observation in fruit flies that some with an antisense mRNA caused by a transposon grew larger and lived longer, presumably due to the switching off of a gene.
    The way it’s taught in school, Darwin rendered Lamarckism obsolete (even though Darwin himself shifted toward a more Lamarckian view later in life.)  But surprisingly, in Science this week,1 four biologists make the case for a Lamarckian mechanism of evolution.  Although physically acquired characteristics may not be heritable, culturally acquired characteristics can be.  You may not inherit your grandfather’s wooden leg, for instance, but you might pass on his stories to your children.  The authors claim that many animals can learn by watching, and pass on what they learn: a bird might learn a new mate attraction technique by watching another bird, or a mouse might learn that crossing the road is dangerous by watching a friend get run over.  Such cultural lessons are “public information” (PI) that is heritable, they claim, and so cultural evolution (that acts on memes; i.e., ideas, behaviors or styles that spread socially) might influence biological evolution (that acts on genes).  At least, they think, the suggestion deserves more thought:
PI is a widespread phenomenon that is emerging as a potential unifying concept in fields that involve decision-making processes in which individuals can extract information from others to assess resource quality.  The use of PI can enrich evolutionary models and can have marked effects on evolutionary predictions.  Future research should explore the extent to which evolutionary scenarios are affected by the use of PI.
They continue, “the ability of individuals to use PI unites a range of topics as diverse as foraging, predation, mate choice, habitat selection, and colony formation.”  PI may be, in fact, the major driving force in social evolution, and may imply that cultural evolution is more widespread than previously thought.  “Moreover,” they propose in conclusion, “although much work has been devoted to exploring how biological evolution affects culture, we suggest that evolutionary biologists should also consider how cultural evolution influences biological evolution.”
1Étienne Danchin, Luc-Alain Giraldeau, Thomas J. Valone, and Richard H. Wagner, “Public Information: From Nosy Neighbors to Cultural Evolution,” Science, Vol 305, Issue 5683, 487-491, 23 July 2004, [DOI: 10.1126/science.1098254].
Even though it is amusing to watch the Darwin Party argue over which mechanism they like best, it is all beside the point.  As Phillip Johnson pointed out over a decade ago in Darwin on Trial, none of these mechanisms establish the very thing that Darwin set out to explain in the first place: that unguided natural processes unaided by any intelligent design had creative power to generate eyes, ears, wings, intelligence or any other complex feature; nor did Darwin or his followers find any historical evidence that a long chain of intermediates actually ever existed.
    Physical similarity is not enough as evidence for evolution.  Even creationists like Linnaeus were intimately acquainted with similarities between organisms.  The ability to classify organisms according to similarities is insufficient to establish the claim that humans had bacteria ancestors; it might establish just as well that all organisms had a common Designer.  The two proposals above fail again on both counts.  Neither demonstrates any creative power, and neither points to any plausible chain of intermediates.  To expect transposons are somehow creative and can generate complexity is to endow them with angelic powers.  To expect that public information in a herd of theropods could help them sprout wings seems ridiculous.  Where is the evidence any creative innovation was produced by these or any other proposed mechanisms?  It is not only missing; the evidence we do have points in the opposite direction: (1) the Cambrian explosion shows a sudden appearance of complexity without precursors, and (2) the law of entropy demands that information (public or not) degenerates through transmission rather than improves.
    Evolutionary theory is like a smorgasbord of rotten food.  The cooks keep thinking if they add one more dish, customers will find something they like.  Instead, it has turned into a food fight.

Zoo Monkey Walks Upright    07/22/2004
For what it’s worth, there’s a story going around about a macaque in an Israeli zoo started walking on its hind legs after a near-death experience (see
MSNBC News and picture).  One news source is calling it a missing link, another claiming the strange behavior is due to brain damage.
This calls for a monkey riddle.
Q: If humans evolved from apes, why do we still have apes?
A: Some of them had a choice.
    Paleoanthropologists make a big deal out of finding alleged ancestors that walked upright.  Big deal; chimps can walk upright sometimes.  Some people can walk on all fours.  It only takes a chiropractic trick to make an ape-man walk upright; didn’t they see Ringo Starr, John Matuczak and Shelley Long in “Cave Man”?  Maybe Natasha will stimulate a new theory that walking upright is a result of brain damage.  Find a monkey that can type Shakespeare and we’ll pay attention (see 05/12/2003 headline).

Think Before You Speak    07/25/2004
Children are capable of thoughts before they have the words to vocalize them, according to a study published in Nature July 221 (see also summary by Paul Bloom in the same issue2 and report on
Science Now).  This contradicts the postmodernist view that thought is conditioned by language, and instead suggests that humans are innately capable of conceptualizing things, and that words are merely the tools for expressing thought.  Psychologists experimented with 5-month old infants and concluded that “Language learning therefore seems to develop by linking linguistic forms to universal, pre-existing representations of sound and meaning.”  Babies have a plasticity to concepts regardless of language, but “as they grow up, children place less importance on concepts that aren’t emphasized in their language.”  Bloom thinks this reinforces the old view of St. Augustine on learning to speak: “By constantly hearing words, as they occurred in various sentences, I collected gradually for what they stood, and having broken in my mouth to these signs, I thereby gave utterance to my will.”

Ever have a thought in your mind but couldn’t express it in words?  Maybe that’s the frustration a baby feels.  She is thinking, “Action-oriented orchestration of innovative inputs generated by the escalation of meaningful indigenous decision-making dialogue can maximize the vital thrust toward a non-alienated viable urban infrastructure contingent upon third-generation time-phase conceptualization,” but all that comes out is “goo goo gah.”  Mothers seem to understand all this on their internal Babynet wavelength, but dads should learn to pay better attention.

A press release from
University of Vermont says, “Geologists Discover Water Cuts Through Rock at Surprising Speed.”  A five-year study concluded that the Susquehanna and Potomac rivers cut through 10 to 20 meters of solid rock in 35,000 years, “a rate far more rapid than previously thought,”  especially since most of the cutting occurred during a “short-lived pulse of unusually rapid down-cutting” in their estimation.  They claim that regional climate change was a bigger factor than glacial meltwater.  Their work is published in the July 23 issue of Science.1  The synopsis says, “One of the most basic geological process is the incision of bedrock by rivers, yet little is known about the rates or timing of this process along passive continental margins like the eastern seaboard of the United States.”
1Reusser et al., “Rapid Late Pleistocene Incision of Atlantic Passive-Margin River Gorges,” Science, Vol 305, Issue 5683, 499-502, 23 July 2004, [DOI: 10.1126/science.1097780].
The authors don’t mention previous estimates for the age of these gorges.  MSNBC News claims it is twice the previous estimate, but with more water the erosion could have been even more rapid.  Science News, on the other hand, says “These erosion rates are tens to hundreds of times faster than scientists had suspected.”
    One can imagine Charlie and Charlie (Lyell and Darwin, respectively) standing on the banks and thinking, “My, my, my; that must have taken millions of years.”  Not necessarily.  Even if the current estimate (37,000 years) is still off by an order of magnitude, compare that with the problem the uniformitarians face: things are happening too fast.  How can animals evolve when the ground is disappearing under their feet?  At least geologists are making regress on their inflated dating methods.  The climate is changing; floods of evidence are rapidly eroding Charlie L.’s fluffy bedrock on which Charlie D. built his house of cards.

Plant “Evolutionary Leftover” Now Deemed Vital    07/22/2004
Photorespiration, “a biological process in plants, thought to be useless and even wasteful” and “just an evolutionary leftover” from an age when carbon dioxide was more prevalent, has been found to be “necessary for healthy plant growth and if impaired could inhibit plant growth,” according to a UC Davis study published in PNAS.1 (see also summary on
EurekAlert).  It functions as a way to inhibit nitrate assimilation.  Some agricultural scientists assumed it was an unnecessary process to be genetically engineered out of plants because it was wasteful, “But the new UC Davis study suggests that there is more to photorespiration than meets the eye and any attempts to minimize its activity in crop plants would be ill advised.”
Evolutionary presuppositions have once again stood in the way of scientific progress.  A design model would have looked at the phenomenon as there for a reason, and sought to determine what it was.  These scientists had to ignore Darwinism to get at the truth.  And we’re supposed to believe that nothing in biology makes sense except in the light of evolution?  The new version should be, “nothing in Darwinism makes sense in the light of biology.”

New Book Reveals China’s Cambrian Explosion   07/22/2004
Nature July 221 has a book review about the first volume in English of the Chengjiang biota of China, where tens of thousands of soft-bodied organisms are preserved in early Cambrian strata.  The book, The Cambrian Fossils of Chengjiang, China: The Flowering of Early Animal Life by Xian-Guang Hou et al., is praised by reviewer Zhe-Xi Luo, who puts a positive spin on the problem of the Cambrian explosion:
These beautiful and unique fossils have inspired new scientific insights and led to the clashing of ideas.  There is a great debate on the likely positions of Chengjiang animals such as the yunnanozoans in the deuterostome family tree.  Such debates will surely redefine the phylogenetic framework for establishing the earliest evolution of key features of chordates....
....it also provides an update on the fast-paced attempts to decipher the full evolutionary significance of this palaeontological treasure.....
....The early animal fossil record, however incomplete, can tell us about the early diversification of major animal lineages, a hot topic for molecular evolutionary studies, especially with regard to the timing of early animal evolution.  The Chengjiang fossils are the best source of evidence about the emergence of animal body plans, and have attracted interest from students of evolutionary development....
....the Early Cambrian sea of Chengjiang really is a cradle of early chordate evolution.
In the film
Icons of Evolution, paleontologists onsite at the Chengjiang beds demonstrate that while soft-bodied fossils appear in the early Cambrian beds, including items as delicate as sponge embryos, no fossils appear in the preCambrian beds just below them, even though conditions were suitable for preservation.  The paleontologists also explain that all the phyla appear abruptly in the Cambrian beds.  Biodiversity actually decreases in the higher layers, contrary to the predictions of Darwin’s tree of life diagram.
    In the same issue, Andrew B. Smith2 comments on a fossil found in the same Chengjiang beds by D. -G. Shu and Simon Conway Morris et al.3 that they claim is a primitive echinoderm.  The phylogeny of echinoderms, which includes starfish and sea urchins, has long been a puzzle.  “If correct” about this fossil claimed to be 520 million years old, he asserts, “this links the echinoderms to an enigmatic group, the vetulicolians, remains of which are found in the same deposits of early Cambrian age.”  Making the connection with this enigmatic group poses a major difficulty, he says, “because of the difficulty of interpreting even their basic anatomical organization.”  Although echinoderms are placed within the deuterostomes (a “very diverse group” of animals with a mouth and anus which includes all the vertebrates), “in terms of morphology echinoderms have always stood apart because of their aberrant symmetry and lack of structures known as gill slits” unique to deuterostomes.  Starfish, with their five-fold symmetry radiating from a center, don’t fit the pattern of other deuterostomes.  Smith seems to remain unconvinced of the connection at this point:
There is now direct fossil evidence that all of the major deuterostome groups were established by about 520 million years ago.  Fossil vertebrates (yunnanozoans), tunicates (Shankouclava) and both asymmetric and radiate echinoderms (homalozoans, helicoplacoids) have all now been discovered in early Cambrian deposits.  Phlogites, a tentacle-bearing early Cambrian fossil of uncertain affinity, might even be a hemichordate or part of the common ancestral lineage of echinoderms and hemichordates.  So, if deuterostome divergence occurred around 575 million years ago, as recent molecular-clock studies suggest, there is a 50-million-year gap in the fossil record between the origin of deuterostomes and their appearance in the fossil record.  In the jigsaw of deuterostome evolution, vetulocystids represent another piece to be fitted into a puzzle where many of the pieces are still missing.

The spinmeisters of the Darwin Party, like this book reviewer, sound for all the world like a Stalinist explaining the benefits of the new Five-Year Plan.  Smith seems to be saying “not so fast” as he owns up to the mystery of the Cambrian explosion: all the major groups of animals, including vertebrates, appear suddenly in the early Cambrian without ancestors.  Think of all the changes that must take place to turn an organism with bilateral symmetry into one with pentaradiate symmetry like a starfish.  The first uncontested fossil echinoderm is already a full-fledged echinoderm.  Why is this so puzzling?  It’s only a puzzle if you’re trying to draw a mythical tree between the dots that is only a figment of philosophical imagination.

SETI Researcher Predicts Success Within 20 Years   07/21/2004
According to
New Scientist story reported on EurekAlert, Seth Shostak of the SETI Institute predicts we will know within 20 years if there is intelligent life out there in the Milky Way.  He plugged his numbers into the Drake Equation and estimated between 10,000 and a million radio transmitters spreading messages across the galaxy.  He bases his two-decade prediction on that number and the rapid improvement of computer search technology.  A member of the SETI League criticizes the estimate because “the ‘other end’ of the communications link is completely out of our hands.  It would be nice to think we know something about the existence, distribution, technology and motivation of our potential communications partners in space, but in fact, we don’t.”  Shostak defended his prediction in spite of the “myriad uncertainties” surrounding it, because “I have made this prediction using the assumptions adopted by the SETI research community itself.”
No inbreeding of thought there, huh?  How about using the assumptions of the ID community?  Speculation is fun but impractical.  He knows few will check back in 2024 to see if he was right, so it serves to get notoriety in the news and maybe additional public support (or funding).
    Seth Shostak appears briefly in the new film about to be released, The Privileged Planet.  He should watch it.

Engineers Envy Diatoms’ Glass-Sculpturing Prowess   07/21/2004
What is it?  An ornate crown?  A crystal serving dish cover?  A work of art?  The photo on the cover of the July 17
Science News, labeled “silicon jewels,” is a microphotograph of a diatom, a one-celled organism that lives in the sea and builds itself a glass house too small to see with the naked eye.  There are thousands of species of diatoms, each with a unique shell design.  The article has more diatom photos: one that looks something like a bent sombrero made out of a collander with two goblets sticking out, another that looks for all the world like an Indian tom-tom, complete with stitching, and another that looks like a sunflower head complete with Fibonacci spirals (see 11/20/2003 headline).  Others look like sieves, gears, triangles, stars, and many other shapes both common and extraordinary.
    Scientists dreaming of nanotechnology can’t get over the skill of diatoms in glass manufacturing (see 03/19/2002 headline).  Diatoms are inspiring world-wide efforts to probe their secrets, so that engineers can mass-produce useful molecular devices like photonic crystals and lenses (see 01/29/2003 headline), gas sensors, miniature reaction tubes and other microscopic structures of high tensile strength (see 02/19/2003 headline).  Though focused on scientists imitating nature, author Alexandra Goho shares some amazing facts in passing about diatoms:
  • Ecology:  Scientists have long prized diatoms... because they remove large amounts of a greenhouse gas—carbon dioxide—from the atmosphere.
  • Glass:  The cell wall of this unicellular organism is made entirely of glass.  More precisely, diatom shells consist of silica, or silicon dioxide, the primary constituent of glass.
  • Art:  Many shells are ornately patterned with features just tens of nanometers in size.
  • Efficiency:  Joanna Aizenberg of Lucent Technologies’ Bell Laboratories in Murray Hill, N.J., says, “We can think of diatoms as living silicon chips.”  Semiconductor-chip manufacturers carve micro- and nanoscale features out of blocks of electronic and optical materials—a costly and time-consuming endeavor.  Diatoms build structures out of silicon much more efficiently.
  • Throughput:  Once researchers figure out how to engineer useful devices out of diatom shells, they could enlist the reproductive capabilities of diatoms to generate trillions of silica structures in a matter of weeks.  Some species of diatoms can replicate up to eight times a day.  Sandhage says, “For a fairly small number of reproductions, you could get incredibly large numbers of the exact-same three-dimensional structure.”
  • Flexibility:  Diatoms can make just about any structure you can imagine.
  • Technique:  It begins when the algal cell divides, forcing it to split its shell into two halves.  The new cells, each now bearing only half a shell, begin to reconstruct their missing halves by taking up silicic acid—a simple compound of silicon, oxygen, and hydrogen—from the surrounding water.  Each new organism deposits the silicic acid in a compartment called the silica-deposition vesicle.  There, the chemical is converted into silica particles, each measuring about 50 nm in diameter.  These then aggregate to form larger blocks of material.  Researchers speculate that a set of special proteins guides the formation of the silica particles and their subsequent assembly into larger structures.  Hildebrand says that other cellular proteins outside of the vesicle stretch and mold the compartment to shape the silica inside.  Once the half shell is complete, the vesicle merges into the cell’s membrane, exposing the newly created structure.
  • Genome:  Scientists are searching for the protein-coding genes among the diatom’s approximately 11,000 genes....
  • Programming:  Diatoms of the same species consistently form shells with exactly the same pattern, suggesting that the designs are genetically programmed.
  • Catalysis:  Nils Kröger, a diatom biologist at the University of Regensberg in Germany, was the first to identify the silica-forming proteins in diatoms.  The molecules of this class, which he calls silaffins, are unusual among proteins in that many of them have long side chains of organic molecules known as polyamines.  The proteins are also decked out with an assortment of other molecules, including sugars and phosphates.
        When Kröger and his colleagues added silaffins to a test tube containing silicic acid, tiny silica spheres formed in a matter of minutes.  In contrast, a solution of silicic acid without any proteins “can take hours or even days to form hard silica,” says Kröger.... “we don’t completely understand how it works.”
  • Individuality:  Each protein does something different: One produces spheres, one makes porous shapes, and the third forms platelike structures.
        Moving beyond these simple shapes will require a greater understanding of the diatom’s molecular machinery.  What’s more, dozens or even hundreds of proteins may govern the shell-formation process.  Mapping the myriad interactions among all the components could be a daunting task.
  • Green and Clean:  Fabrication of silicon chips and other electronic devices currently requires harsh chemicals and generates much waste.  Diatoms and sponges [see 08/20/2003 headline] know how to produce materials under ambient conditions without these harsh chemicals,” says Aizenberg.  “And yet the end result is the same.”
Goho’s article is seasoned with high praise for the abilities of these miniature factories.  “We’re just scratching the surface” to understand them, says one, and another wants to “harness the power of biological materials.”  But they stand humbled at the creative power of these little organisms:
“It will be impossible to reproduce this process in a test tube because it’s such a complicated cellular process,” says [Mark] Hildebrand [of Scripps Institute].
    [Joanna] Aizenberg [of Bell Labs] adds, “The question is, ‘Will we be able to bridge the gap between what goes on in nature and what we can do in the lab?’”
So how did these tiny one-celled organisms achieve “manufacturing prowess” that makes our best engineers stand in awe? “Nature has been building things on the nanoscale for a long time,” says materials scientist Ken Sandhage of the Georgia Institute of Technology in Atlanta.  Alexandra Goho ends, “Materials scientists are only beginning to uncover the secrets of this aquatic community of glass-sculpture artists produced over millions of years of evolution.

Gag!  Choke!  This is like watching a spectacular stage show then being expected to bow to a fat Charlie image at the end.  We were all set to applaud and praise this well-written glimpse into another wonder of nature, a wonder that shouts intelligent design, and then Goho has the gall to say evolution over millions of years produced “glass-sculpture artists” with 11,000 genes, hundreds of which work together in coordinated fashion to build unique, exquisite, precision structures out of glass without pollution or waste of energy.  Unbelievable.  Did any of the scientists present any evidence that evolution could do such a thing?*  No; in line with the stinking habit of the Darwin Party, they merely assumed evolution did it, because they have committed their lives, their fortunes, and their sacrilegious honor to the philosophical belief that there is no God, no Creator, no intelligent Designer.  Their faith forces them to believe the absurd, in spite of the evidence.  This one example should be enough to make any clear-thinking scientist toss Charlie’s figurehead overboard, but thumb through a few more “Amazing” Chain Links below and ask yourself how many other wonders of nature we are asked to believe happened by mindless, chance processes.  Phooey; a wonderful science story was ruined by the last sentence.  So instead of praising this article unequivocally to the tune of This Is My Father’s World, it saddens us to have to sound the Bronx cheer as we hand out another Stupid Evolution Quote of the Week award.
    Enough of that.  Just marvel for a minute at the manufacturing skill of these tiny robotic factories.  God could have made the earth so boring.  He could have provided just enough design to permit survival.  There could be brown sky, brown scum, brown water, and we could all subsist on mud.  He could have fashioned little amorphous sponges to soak up the carbon dioxide and keep Earth from overheating.  Instead, He gave us a superabundance of “useless beauty,” exquisite crystal jewelry filling the seas, a wonder to silently lay undiscovered till the invention of the microscope.  Considering the thickness of diatomaceous earth beds (see 02/02/2004 headline), trying to count the number of intricate glass sculptures that have reproduced themselves by the elaborate preprogrammed process described above would be like trying to count the snowflakes or the stars.  As the Moody Science Classic film Hidden Treasures teaches, diatoms are miniature marvels that should remind us God cares for each one of us.

*For an example of how Darwinists gloss over the difficulties in explaining how glass-crystal factories could evolve, look at the article by Falkowski et al. in the July 16 issue of Science.  Even though their paper is entitled, “The Evolution of Modern Eukaryotic Plankton,” and discusses diatoms explicitly, they provide not even a hint of a suggestion about how the critters “evolved” the ability to make reproducible glass artwork.  Instead, the article is filled with glittering generalities about alleged diatom phylogeny.  They moan that “the origin of diatoms is more obscure” than the obscure evolution of other phytoplankton.  They groan that “the fossil record is inevitably incomplete.”  In spite of the lack of evidence, they merely assume that diatoms figured out their abilities by themselves: e.g., “diatoms have evolved a nutrient storage vacuole.”  How did they do that?  As usual, they don’t say (see 05/18/2004 headline).  The only weird-science suggestion they can come up with is that the rise of diatoms (in their evolutionary timeline) seems to have coincided with the invasion of land by grasses, and that grasses are more effective at leaching silica from the soil so that it erodes into the sea, where the diatoms need it.  Satisfied?
Plants Are World Travelers    07/20/2004
We think of plants as stationary life forms anchored to the soil, but
National Geographic News reminds us that they have remarkable ways of getting around via seed dispersal mechanisms.  Some fly through the air with parachutes or helicopters, some float in the water, and some rely on animals.  It appears that some exotic species may be vanishing because animals they relied on for dispersal have gone extinct.
A wonderful film that reveals the hidden world of seed dispersal is the award-winning Moody science classic Journey of Life.  This is a must-see nature film.  Follow delicate packages of life as they travel through the air, across oceans and continents, down rivers, through fires, ride on birds and monkeys and cows, roll through the West, explode across the field and even crawl across the soil and drill themselves in the ground.  The time-lapse and slow-motion photography is stunning.  This “sermons from science” film ends with an analogy to another seed spoken of by the Lord Jesus in one of his parables: the word of God.  The film would make a great introduction or conclusion to a local nature hike.

Dark Energy Is Embarrassing    07/20/2004
Robert Scherrer is trying to come up with a theory that combines dark matter and dark energy, reports
Space.Com.  “It is somewhat embarrassing to have two different unknown sources for the dominant forms of matter and energy in the universe.  On the other hand, that may just be the way things are.  We don’t get to pick the universe we live in.”
    Yet if he is right, it makes other cosmologists uneasy.  Writer Robert Roy Britt explains, “There is one glaring problem with the idea, which Scherrer admits to.  It implies that we live at a very special moment in time when the energy densities of dark matter and dark energy are roughly equal.  Scientists hate coincidences.”
Cosmologists have been chewing on their two fudge factors, dark matter and dark energy, for years now.  Too much fudge causes truth decay.  The only wise crack in this article is that we don’t get to pick the universe we live in.  If it appears coincidental that our universe is special, deal with it.

Dinos Found in Spain, Croatia    07/20/2004
Dinosaur fossils continue to be discovered around the world.  The
BBC news hints that surprises may be forthcoming from a new cache in Spain that has yielded stegosaurs, crocodilians and carnivorous dinosaurs, and a pelvic bone possibly from Diplodocus.  On a resort island of Croatia, trackways of titanosaurs have been discovered, reports EurekAlert.  The BBC is celebrating the bicentenary of the British scientist who gave us the word dinosaur, Sir Richard Owen; see Taipei Times story.
Richard Owen was a strident opponent of Charles Darwin, and had more credibility than Darwin in 1859.  Same could be said of Adam Sedgwick, the man who taught Darwin geology.  Darwin was deeply hurt that these two eminent scientists rejected his theory, but his four musketeers (see 01/06/2004 headline) saw to it that their bearded buddha got elevated to the pantheon anyway (see 02/13/2004 commentary).
