Provine/Nelson

As an undergraduate studying evolutionary biology — like many other such students, I suppose — I read Will Provine’s classic The Origin of Theoretical Population Genetics (University of Chicago Press, 1971), a standard history of the laying of the mathematical and conceptual foundations, in the work of Fisher, Haldane, and Wright, of what later came to be known as the Evolutionary Synthesis (i.e., textbook neo-Darwinism).

When Chicago reissued the book in 2001, Provine added a remarkable Afterword. With characteristic candor, he wrote that “my views have changed dramatically.” Natural selection, for instance, Provine no longer saw as a “force” or “mechanism” of any kind:

Natural selection does not act on anything, nor does it select (for or against), force, maximize, create, modify, shape, operate, drive, favor, maintain, push, or adjust. Natural selection does nothing….Having natural selection select is nifty because it excuses the necessity of talking about the actual causation of natural selection. Such talk was excusable for Charles Darwin, but inexcusable for evolutionists now. Creationists have discovered our empty “natural selection” language, and the “actions” of natural selection make huge, vulnerable targets. (pp. 199-200)

On November 12, Provine is sponsoring a debate (with me) at Cornell University, where the question on the table is this: If textbook neo-Darwinism — the Evolutionary Synthesis — fails, what follows? I’ll argue that ID gains support; Will tells me he’s going to argue that ID gets bupkis. But we’ll start by summarizing where we agree about the shortcomings of the standard theory.

The debate, moderated by Allen MacNeill, will occur in Room B45 of Warren Hall, at 4:30 PM on Monday, November 12. A dinner will follow at the Hans Bethe House.

johnnyb can you give me some references I have been poking around in this area for some time but have been unable to make any sort of rational contact with anyone on the subject. The neo-Darwinian program clearly wont work since for any rare genetic change, specifically the addition of a new gene, the process becomes strictly a genetic lottery and should obey the statistical distributions of such a lottery with the probability proportional to the number of "tickets" or individuals in the population whereas in the real world all species acquire new genes at essentially the same rate independent of population size. It is easy to show that the possibility of an organism actively evolving in a preferred direction is compatible with all known physics, chemistry and biology other than the "principles of neo-darwinian evolution". There are some very severe restrictions on when and how such evolution can occur but there is no grounds for excluding it. I have a paper at www.nsof.co.nz which explores the mathematics and mechanisms of such evolution. Such explanations have the huge advantage of exactly matching observation and the fossil record without any recourse to ID.David R A Finn

johnnyb, Are we not talking about apples and oranges? One is the immune system and not gamete cells that are changing due to environmental stress to save the current organism. Is there any evidence that the DNA of gametes are being modified due to specific environmental pressures to meet the stress better for their offspring? I am talking about multi-celled organisms that sexually reproduce. The debate is not over what happens to bacteria. I am aware though far from knowledgeable that bacteria are constantly changing to meet environmental pressures but essentially remain bacteria and nothing really new happens. If what I said is not true then this is worth several threads.jerry

Jerry: "No one is proposing that the organism itself can change its own genome by any means." That is absolutely what is being proposed. That is in fact what is happening. Faced with a biological problem, the organism initiates change mechanisms based on the type of stress it is facing, which then performs mutations until the right answer is reached. This is empirically documented time and again. The immune system is a prime example, and the SOS response of a bacteria is another one. ajl -- The exact mechanisms are not known, but my guess is that it is very similar to non-deterministic computer programming. That is, you harness statistical randomness in specific ways, which guarantees good results in the face of adversity better than any other mechanism.johnnyb

bfast, I am not sure what you are trying to say. I suggested a thread about this a few days ago and then I found there was one over at telic thoughts at that time. The telic thoughts site seemed screwed up at the moment. The first page has threads from a month ago so recent threads are currently missing. I mentioned that I did not know how the mouse was changed and asked if anyone had any ideas. On the telic thoughts thread someone said that a gene was implanted at a promoter site and this caused the specific enzyme to be expressed at 20 times the normal rate. And apparently this addition to the genome caused the change. It apparently caused increased mitochondria denisty but this was not planned but happened serendipitously. So as I said I await a discussion and more knowledgeable persons than I to dissect just what was done to the mouse genome. It is a scary phenomena because these mice have the potential to upset an ecology and from what I understand are very aggressive.jerry

Jerry:
We have an example last week where scientists developed a new mouse with superior endurance, life expectancies and breeding success. So here is an example of intelligent design in our time.
The mice you refer to deserve a thread in themselves. You make it sound like the scientists did some amazing engineering, where what they actually did was remove a gene. The fact that mice, minus one gene, are super-mice makes painfully little sense in light of the modern evolutionary theory. I see this as similar to children's snowmobiles. They have a significant engine so that they can function in a variety of conditions, but they have an active governor so that they don't endanger the child. Likewise it appears that mice are overengineered, possibly for similar reasons, but they have a governor gene. I suspect that they are governed to maintain the balance of nature, but I find it difficult to envision that they are governed to give themselves a competitive advantage, even thought they require more food.bFast

WesternJoe, No one is proposing that the organism itself can change its own genome by any means. There is no evidence for this at all though different versions of this were popular in the 19th and early 20th century. How variation originates is the major mystery of evolution. ID proposes that in some cases it is due to intelligent causes. Though not all cases. We have an example last week where scientists developed a new mouse with superior endurance, life expectancies and breeding success. So here is an example of intelligent design in our time. There are points of view that the origin of all variation is natural and no intelligence was involved at all. That is the essence of this thread. Allen MacNeill claims his 47 processes can explain everything or in cases where there is some doubt it is only a matter of time before other naturalistic process are uncovered to explain things. The position of ID is that there is no evidence other than for trivial examples that can be attributable to these 47 naturalistic processes. As I said it is a mystery and that is what most of the debate is about.jerry

Jerry: "The whole issue that is being debated in evolution is the source of the variation. Natural selection is a side shoe." I agree. But then again, if variation emerges nonrandomly from within each creature, selection is left out of the loop other than being merely a conservative force. Also, if variation emerges nonrandomly, one must attempt to answer how this nonrandom variation occurs in the first place. From where does this wisdom come from? If it's the mental capabilities within each creature that's perceiving the environment and then acting accordingly, adaptively manipulating its physical structure, then what we have is a science of the mind, not a science of the mind, because the body then just becomes just a servant to the mind. If mental processes are thus in charge of evolutionary change, it must be questioned how in the world the mind of a creature can transform itself into a mind of a completely different kind of creature. I think this spells big trouble for science, who attempts to explain things materialistically and naturally.WesternJoe

ajl: how does front loading happen? A designer would have a target/ goal in mind and provide the programming/ information and resources required to reach the target/ goal. Artificial selection could/would be a driving force. See also "Evolving Inventions" SciAm Feb 2003 (JR Koza, M. Keane, M. Streeter)Joseph

WesternJoe, It is the source of the variation that is the issue and there is no reason it has to be random. That is something to be proved. For all Darwin knew the variation was present in all the members of the population and then when the population met a new environment, the variation that was most appropriate for the particular niche in which the organism found itself would eventually take over. Sort of like dog and pigeon breeding which Darwin used extensively in his book. The whole issue that is being debated in evolution is the source of the variation. Natural selection is a side shoe. To assume variation is random is begging the question. You are assuming an answer is true when what has to be proved is this answer.jerry

Appreciate everyone's answers...thanks for the info.... Jerry said this: "WesternJoe, You said “Natural selection, by definition, selects random genetic variants” No that is not correct. The word random should be removed from your phrase." --------- As I understand it, it is natural selection that is responsible for building up populations genetically. Therefore, in order to do so, it must select from random genetic variants. If the variants are not random, there is no sense in saying selection is responsible for anything in regards to adaptive change....if all the organisms in a population experience the same non-random cues then they are all likely to change as a result. Selection's only role would then only be to weed out the freaks, runts, and underdeveloped.....or that's how I see it. Thanks again for all the info. Joe.WesternJoe

johnnyb, As a follow up question (thanks for the good description of front loading): - how does front loading happen? That is, let say humans aren't the "final frontier". Perhaps from humans, another species will emerge, say one with eyes in the back of their heads. So, what happens? Does the Designer choose who gets to have the 3-eyed child? That is, is it your kids or my kids that have the three eyes? And, if its just mine, how do we keep the lineage growing. My kids have to have lots and lots of kids, or the line will die out. If its multiple people having 3-eyed kids, how is that timed? Does the Designer say in 2008 that x number of humans born will have 3 eyes? Also, if its just one, and you are the one, did the Designer know you would be created from your grandparents, great,great,great grandparents, etc.? And, did the Designer know that you would not die before your had a chance to reproduce? Front loading seems really logical, given the information in the genome, but with NDE or even front loading I'm having a very hard trying to "spin a story" as to how it could have happened. Any thoughts?ajl

WesternJoe -- I _think_ I understand your question, but I apologize if I answer another one. For those who believe in both near-universal (or universal) common ancestry as well as intelligent design, the novelty comes from one of two sources: 1) progressive creation events 2) front-loaded evolution #2 is the more interesting to me, even though I don't believe in universal common ancestry. In #2 the original organisms were pre-configured with enough information to produce divergence. So, for those in the universal common ancestry camp, that means that the original unicellular organisms contained either the information for producing multicellular life (in at least somewhat of a dormant state), or they had sufficient information to produce such variations as needed. The reason, then, for such events as the Cambrian explosion, is that this is simply a combinatorial arrangement of existing genetic material. This is why we never find true intermediate structures. Even if a structure is in its first time to be generated ever, it is using sufficient information to make it in a fully-functional, fully-usable state. This is also a possible reason why the "tree of life" is actually a bush. The early divergences were simply recombining existing patterns already present in the genome. This would lead to very large amounts of overlap in terms of genetic and phenotypic diversity in different groups, since in the earliest forms they were all from essentially the same gene toolkit, and retained those genes dormantly for some time afterward. telicthoughts.com covers discoveries in this area quite frequently.johnnyb

WesternJoe, You said "Natural selection, by definition, selects random genetic variants" No that is not correct. The word random should be removed from your phrase. The whole debate is over where the variation comes from and so far random processes are inadequate to supply the variation that exists in populations. As I just said on another thread, natural selection is working all the time. It just has little new to work with so it essentially ensures the status quo as opposed to producing new phenotypes. So the 64 dollar question is where diid the variation come from.jerry

WesternJoe:
I’m still trying to understand how common descent can happen without natural selection. I have yet to hear a logical explanation.
Joe, please look at exactly what common descent means -- it means that every organism has a parent, or in the case of single-celled organism, every organism is the result of the division of its predicessor (parent) into two. That's all it means -- how variety occurs within this simple paradyme is not defined by the term "commmon descent". If genetic engineers modify a mouse, they begin with a living mouse, they add a gene, then they let the modified mouse produce offspring. Is the resultant geneticly modified mouse somehow not the a common ancestor of its mother and father? Of course it remains to be a common ancestor, common descent is not destroyed. By the same token if an unknown designer twiddles with genes, common descent is not broken just because twiddling happend. Secondly, the front-loading community, such as Patrick, will point out to you that it is not at all unreasonable for the first living organism to contain a pattern of DNA that is not implemented in that organism, but is passed on to its children in such a way as to guide the development of modified offspring. (The front-loading hypothesis is somewhat more complex than that, but its a good summary.) Again, if the offspring implement the embedded code, common descent is not broken even though it is not natural selection, or not purely natural selection that is guiding the process. Therefore there is no common descent = natural selection eqation. Natural selection requires common descent, but common descent does not require natural selection.bFast

Natural selection is therefore a result of three processes, as first described by Darwin: Variation Inheritance Fecundity which together result in non-random, unequal survival and reproduction of individuals, which results in changes in the phenotypes present in populations of organisms over time.- Allan McNeil on Telic Thoughts
Also there is: The Strength of Natural Selection in the Wild:
Natural selection disappears as a biological force and reappears as a statistical artifact. The change is not trivial. It is one thing to say that nothing in biology makes sense except in the light of evolution; it is quite another thing to say that nothing in biology makes sense except in the light of various regression correlations between quantitative characteristics. It hardly appears obvious that if natural selection is simply a matter of correlations established between quantitative traits, that Darwin’s theory has any content beyond the phenomenological, and in the most obvious sense, is no theory at all. Be that as it may, the real burden of Kingsolver’s study lies in the quantitative conclusions it reaches. Two correlations are at issue. The first is linear, and corresponds to what in population genetics is called directional selection; and the second quadratic, and corresponds either to stabilizing or disruptive selection. These are the cornerstones of the modern hill and valley model of much of mathematical population genetics. Kingsolver reported a median absolute value of 0.16 for linear selection, and a median absolute value of 0.10 for quadratic selection. Thus an increase of one standard deviation in, say, beak finch length, could be expected to change fitness by only 16 percent in the case of linear selection, and 10 percent in the case of quadratic selection. These figures are commonly understood to represent a very weak correlation. Thus if a change in the length of a beak’s finch by one standard deviation explains 16 percent of the change in the population’s fitness, 84 percent of the change is not explained by selection at all.

I'm still trying to understand how common descent can happen without natural selection. I have yet to hear a logical explanation. Natural selection, by definition, selects random genetic variants....and as a by-product of eliminating NS from the equation, one, it would seem, would also have to eliminate the idea that random genetic variants fuel evolution, and thus, common descent. People like Behe doubt that NS has any real power to evolve a population of organisms into different types of organisms, but what exactly is the explanation for common descent without it?WesternJoe

Natural selection is a process that is constantly at work in nature. It just has trivial things to work on in terms of evolutionary biology so it produces trivial results in this area. In terms of genetics and medical issues it can be an exceedingly important process.jerry

Natural selection does nothing…."
It is nice to see my view vindicated on here, since I had to argue a while ago about this. NS is not a force or mechanism of any kind, it is the description of a result; it doesn't cause anything itself. Nice to find out that even some Darwinists can see this.Atom

Paul Nelson: On ancient DNA http://findarticles.com/p/articles/mi_m1200/is_n20_v147/ai_17128688 Using a technique known as polymerase chain reaction, the scientists copied and sequenced a strand of the B. sphaericus DNA. The purportedly ancient DNA resembled a segment from modern B. sphaericus but did not match exactly, providing further proof that modern bacteria had not contaminated the experiment, the researchers say. As for me, it would very interesting to see if the slight difference between ancient and modern reduced fitness or robustness to any notable extent. (thus conforming to the principle of genetic entropy and thus confirming what is becoming increasingly clear.) It should be noted that the minor variation between ancient and modern bacteria, both at the same time, 1. Proves that the ancient DNA is indeed not a modern contaminant in the amber. (in conjunction with the cross check he did with another ancient amber that had no ancient bacteria in it) And 2. Proves that evolution is indeed not occurring to the bacteria DNA at the minimal accepted and required "molecular clock" rate. For all practical purposes, it seems the best evidence we have for ancient bacteria DNA, strongly indicates that the rate is, in effect, frozen. And the minor variation, while creating insurmountable problems for evolution, turns out to be well explained by Genetic Entropy by preliminary presumptions for Genetic Entropy,,, If a rigorous test for robustness, between ancient and modern bacteria, can be ascertained that will confirm that it is indeed in line with what Genetic Entropy will predict in its full fleshing out, then this evidence will be incontrovertible!bornagain77

Paul Nelson, One more piece of evidence that may, or may not, be of help to you. There are many ancient bacterium fossils recovered from salt crystals and amber crystals that have been compared to their living descendants of today. Some bacterium fossils, in salt crystals, dating back as far as 250 million years have had their DNA recovered, sequenced and compared to their offspring of today (Vreeland RH, 2000 Nature). Scientists accomplished this using a technique called polymerase chain reaction (PCR). To the disbelieving shock of many scientists, both ancient and modern bacteria were found to have the almost exact DNA sequence. “Almost without exception, bacteria isolated from ancient material have proven to closely resemble modern bacteria at both morphological and molecular levels.” Heather Maughan*, C. William Birky Jr., Wayne L. Nicholson, William D. Rosenzweig§ and Russell H. Vreeland ; (The Paradox of the “Ancient” Bacterium Which Contains “Modern” Protein-Coding Genes) http://mbe.oxfordjournals.org/cgi/content/full/19/9/1637 Though they do some weird contortions to try to make the evidence fit an evolutionary scenario in their paper,,,the weight of the evidence from both Behe and Vreeland (not to mention the law of conservation of information by Dembski and Gitt) is very compelling to stasis and does not support macro-evolution happening at all! Those are quite a few lines of evidence converging on that fact! I don't have all the various papers for ancient bacterium stasis, but as Vreeland and his or her colleagues said: “Almost without exception, bacteria isolated from ancient material have proven to closely resemble modern bacteria at both morphological and molecular levels.” So if you can present this evidence of a consistent finding of stasis in almost every ancient bacteria studied, it will be another powerful evidence you can use.bornagain77

Paul Nelson,, I think this one quote from Dr. Behe is very powerful: Darwinists overlook the considerable power of the example of the relatively minor changes in HIV: there have been a truly astronomical number of copies produced in just the past fifty years or so. And because of its much increased mutation rate, it has undergone in the past half century as many of some kinds of mutations as all the cells have undergone in the history of the world. If Darwinism had the power that its boosters claim, we should expect to see truly fundamental changes. Yet despite the enormous number of opportunities, only minor changes have appeared. That is very strong evidence of the strict limits on what Darwinian processes can accomplish.bornagain77

Paul Nelson, This evidence goes along with my post in #31 On page 138 of Dr. Behe's Edge of evolution,, As one study put it "Each and Every possible single-point mutation occurs between 10^4 and 10^5 times per day in an HIV-infected individual." (HIV population dynamics in vivo Collin J.M., 1995). Every double point mutation, where two amino acids are changed simultaneously, in each person once a day. (This means a chloroquine-type resistance mutation-where two particular amino acids had to appear before there was a net beneficial effect-would occur in each aids patient every day. Not that's mutational firepower!) In fact, just about every possible combination of up to six point mutations would be expected to have occurred in an HIV particle somewhere in the world in the past several decades-double the number that could occur in the slower mutating P. falciparum. In addition to all those point mutations, enormous numbers of insertions, deletions, duplications and other sorts of mutations would occur as well. An exactly what has all that evolution of HIV wrought? Very little. Athough news stories rightly emphsize the ability of HIV to quickly develop resistance, and although massive publicity makes HIV seem to the public to be an evolutionary powerhouse, on a functional biochemical level the virus has been a complete stick_in_the_mud. Over the years its DNA sequence has certainly changed. HIV has killed millions of people, fended off the human immune system, and become resistant to whatever humanity could throw at it. Yet through all that, there have been no significant basic biochemical changes in the virus at all... In my opinion this is powerful proof that evolution is not capable of generating the complexity that would be required to change a mammal into a whale or a monkey into a man for that matter.... I expected this one point of Dr. Behe's book to be attacked vigorously by Darwinists. Since HIV is one of their strongest proofs that evolution appears to be occurring. Yet the only major rebuttal of this crucial point of HIV stasis came from a Grad student, named Abbie Smith, on, of all places, Pandas Thumb. His defense of her rebuttal, as well as all other rebuttals that have been levied against his book, are clear, concise, and in fact, the attempts at rebuttals, of his book, actually turn out to make Dr. Behe's position all the stronger, since he is allowed to clearly illustrate the insurmountable problems with Darwinism to the nTH degree.: Here is his rebuttal of Abbie Smith (ERV): http://www.amazon.com/gp/blog/post/PLNK36ZEH0HZZXVX4?ie=UTF8&cdForum=Fx194GZ1VA1S4PW&cdPage=10&cdThread=Tx30AG5NJBKJ6AVbornagain77

YOU ALL ARE MISSING THE POINT!!! ID does not say that evolution cannot happen. It does say that evolution, in order to occur, must be teleological. Nearly all of Allen's list is teleological evolution! Informationally-directed evolution is what ID is all about. Allen's list is _precisely_ a list of informationally-directed mechanisms of evolution.

Gene Structure (in DNA) • (1) single point mutations • (2) deletion and insertion (“frame shift”) mutations • (2) inversion and translocation mutations Gene Expression in Prokaryotes • (3) changes in promoter or terminator sequences (increasing or decreasing binding) • (3) changes in repressor binding (in prokaryotes); increasing or decreasing binding to operator sites • (3) changes in repressor binding (in prokaryotes); increasing or decreasing binding to inducers • (3) changes in repressor binding (in prokaryotes); increasing or decreasing binding to corepressors Gene Expression in Eukaryotes • (3) changes in activation factor function in eukaryotes (increasing or decreasing binding to promoters) • (3) changes in intron length, location, and/or editing by changes in specificity of SNRPs • (3) changes in interference/antisense RNA regulation (increasing or decreasing binding to sense RNAs) Gene Interactions • (3) changes in substrates or products of biochemical pathways • (3) addition or removal of gene products (especially enzymes) from biochemical pathways • (3) splitting or combining of biochemical pathways • (3) addition or alteration of pleiotropic effects, especially in response to changes in other genes/traits Eukaryotic Chromosome Structure • (2) gene duplication within chromosomes • (2) gene duplication in multiple chromosomes • (4) inversions involving one or more genes in one chromosome • (3) translocations involving one or more genes between two or more chromosomes • (3) deletion/insertion of one or more genes via transposons • (2) fusion of two or more chromosomes or chromosome fragments • (2) fission of one chromosome into two or more fragments • (3) changes in chromosome number via nondisjunction (aneuploidy) • (3) changes in chromosome number via autopolyploidy (especially in plants) • (3) changes in chromosome number via allopolyploidy (especially in plants) Eukaryotic Chromosome Function • (3) changes in regulation of multiple genes in a chromosome as a result of the foregoing structural changes • (5) changes in gene expression as result of DNA methylation • (3) changes in gene expression as result of changes in DNA-histone binding Genetic Recombination • (6) the exchange of non-identical genetic material between two or more individuals (i.e. sex) • (7) lateral gene transfer via plasmids and episomes (especially in prokaryotes) • (3) crossing-over (reciprocal and non-reciprocal) between sister chromatids in meiosis • (3) crossing-over (non-reciprocal) between sister chromatids in mitosis • (3) Mendelian independent assortment during meiosis • (3) hybridization Genome Structure and Function • (3) genome reorganization and/or reintegration • (2) partial or complete genome duplication • (2) partial or complete genome fusion Development (among multicellular eukaryotes, especially animals) • (3) changes in tempo and timing of gene regulation, especially in eukaryotes • (3) changes in homeotic gene regulation in eukaryotes • (6) genetic imprinting, especially via hormone-mediated DNA methylation Symbiosis • (3) partial or complete endosymbiosis • (8) partial or complete incorporation of unrelated organisms as part of developmental pathways (especially larval forms) • (9) changes in presence or absence of mutualists, commensals, and/or parasites Behavior/Neurobiology • (9) changes in behavioral anatomy, histology, and/or physiology in response to changes in biotic community • (9) changes in behavioral anatomy, histology, and/or physiology in response to changes in abiotic environment • (6) learning (including effects of use and disuse) Physiological Ecology • (9) changes in anatomy, histology, and/or physiology in response to changes in biotic community • (9) changes in anatomy, histology, and/or physiology in response to changes in abiotic environment
(Numerics reference my notes) My Notes: 1: Dr. MacNiell, are you really suggesting that IDers are so shallow as to think that point mutations are the beginning and end of what we mean when we say RM or more accurately RV (random variation)? And you talk about strawmen?! 2: These are examples where, according to the theory, some DNA duplication process randomly "goofed". IE, RM!! 3: These are the product of some random mutational event, are they not? Or are they the product of a mechanism that was ostensibly developed via RV+NS? 4: Is this an example of a glitch in duplication, or as Spetner suggests, is this a mechanism ostensibly developed via RV+NS? 5: What is the cause of DNA methylation, is it a mechanism developed by an organism, or is it the an organism randomly encountering alcohol and having the expected reaction? In either case its either RV, or a mechanism ostensibly developed thereby. 6: A mechanism developed ostensibly by RV+NS. 7: Is HGT a random event, or is there a mechanism inspiring it to happen, such as a mechanism for organisms to share a resistance; a mechanism which is ostensibly developed via RV+NS? 8: A fun concept. However, I fail to see the non-randomness in such integrations. If there is a non-randomness, it will be explained as a mechanism developed ostensibly by RV+NS. 9: All environmental changes can redily be seen as random variation unless the organism creates the environmental changes itself. If the latter, then it is ostensibly the product of RV+NS. Dr. MacNiel, there is NOTHING in the modern theory of evolution that is not encapsulated by Random Variation and Natural Selection, or its little brother, mechanisms developed by RV+NS. This is not a strawman, your implication that IDs view of evolution is nothing more than point mutations is the strawman!bFast

Paul Nelson, I glanced through "Genetic Entropy" by Dr. Sanford and found some stuff that may (or may not) be useful for you,,, In Appendix 5 page 201 Sanford states: Objection #3-The failure of the Primary Axiom (RM/NS) is not a serious challenge to evolutionary thought. What does it matter if the Primary Axiom is ly flawed and essentially falsified? The primary Axiom (RM/NS) is just one of numerous mechanisms of evolution, and so is not crucial to evolutionary theory. Evolution researchers just need some more time, and some more funding, to work out the few minor kinks in their various theories. Objection overruled: The position is damage control and is clearly false: a. There is only "one" evolutionary mechanism. That mechanism is mutation/selection (the Primary Axiom). There is no viable alternative mechanism for the spontaneous generation of genomes. It is false to say that mutation/selection is only one of various mechanisms for evolution. Yes, there are several types of mutations, and yes, there are several types of selection, but there is still only one basic evolutionary mechanism (which is mutation/selection). The demise of the Primary Axiom leaves evolutionary theory without a viable mechanism. Without any naturalistic mechanism, evolution is not significantly different from any faith-based religion. b. Darwin's only true inovative concept was the idea that the "primary creative force" in nature might be natural selection. Yet he had no conception of genetics or mutation, and therefore had no conception of what was actually being "selected". His general view, that natural selection could explain all aspects of biology, was simply his vigorously advanced philosophical positon. Not until much later did the neo-Darwinists sythesize genetics, mutation, and natural selection - creating the field of population genetics. Only then did Darwinism take on the appearance of real science. Ever since that time mutation/selection has been, and still remains, the singular lynch pin holding together all aspects of Darwinian thought. c. Degeneration is the "precise antithesis" of evolutionary thought. Therefore the reality of Genetic Entropy is positively to Darwinism. Many people are claiming the concept of Intelligent Design cannot be approached scientifically, but is only a matter of faith. However it is obvious in biology the "Null Hypothesis" of Intelligent Design is mutation/selection. We all know that to disprove a Null Hypothesis is to strongly support The Hypothesis. Therefore any scientific evidence which demonstrates that mutation/selection can "not" create or preserve genomes, is sound scientific evidence supporting Intelligent Design. AS well starting on page 195 Sanford addresses the Darwinists attempts to circumvent the problem with mega beneficial mutations:Of note: A duplicated region adds no new information until beneficial mutations are somehow incorporated into it-....but in reality he knows the only way to climb "Mount Improbable" is through a very long series of infinitesimally tine steps. In appendix 4 page 191, Sanford addresses Polyploidy,,it was his special area of study during his PhD thesis! Also of interest; His discussion on transposable elements, page 39; Discussion of required mutation rates, page 43 f,g, and h. population genetics, page 52-53 Synergistic Epistasis, page 109 Waiting for the first mutation, page 125 and, Waiting for recombination, page 126bornagain77

GilDodgen, "The bottom line is that you still have to get from a program like this, to one like this, with no planning, design, or foresight, only random events." Sorry for off topic, but wow! Great piano work. Enjoying the Chopin and Liszt now.mike1962
