Human/chimp DNA similarity: Evidence for evolutionary relationship?by Don Batten First published in: Creation Ex Nihilo 19(1):21—22 December 1996—February 1997 http://www.infres.enst.fr/confs/evolang/actes/_actes24.html Why linguists and anthropologists should be interestedin the aquatic ape theory for the origin of speech. Karl Diller And | Academic Technology for FAS Psychology 1357: Evolution of Language Instructor: W. Tecumseh Fitch Batten’s article is riddled with errors and refers to ReMine’s book — a circular argument is Joe ever presented one.Batten engages in equivocation, some misrepresentation, question begging — the works. But nowhere does he discuss adaptive mutations, except in reference to ReMine’s book (the veracity of which is in question). And, of course, he, like Fred Williams, equates the total number of bp differences between chimps and humans with the ‘Haldane limit’ of 1667 The Aquatic Ape theory page is interesting, but it too, does not once mention anything about numbers of mutations.If anything, that could be used as evidence AGAINST ReMine’s premise, for it discusses preadaptations — a preadaptation would, by definition, remove the necessity for the 1667 to account for it! Did Joe Gallien even READ his links? The third link Joe provides purporting to support ReMine’s claims is a syllabus outline for a class on the evolution of language.It, too, says nothing of the numbers of mutations required. Again, Did Joe even read these links? Or did he just punch in some words in Google and link to whatever came up? Conclusion: Joe Gallien provides absolutely ZERO support for ReMine’s claims, contrary to Joe’s assertion. Strike one!quote: Strike two! Faulty logic. Looking at an event that already happened, we have no choice but to choose the adaptive changes that DID occur in order to assess them! What the creationist is doing here is setting up a classic win-win scenario, as indicated by his illogical third from last sentence. Analogy: Forrest runs from NYC to Seattle. Forrest kept a diary in which he recorded his route, and TV crews interviewed him along the way, so there is verification. Upon arrival in Seattle, there is a group opposed to Forrest — and watching TV - who claim that Forrest could not possibly have run form NYC. They say this because there is no way to know which route he took. They explain that if he went this way, he would end up in Mexico. If he went that way, he would end up in Maine. But Forrest says Here is my diary — I wrote the way I took. Well, says one of the Opposers, Anyone can stand here in Seattle and conjure up the route one took. That doesn’t mean that is the way you did go. You can’t pick your route after you ran it! Strike two is sufficient You’re OUT!

Would not then a more accurate topic be 'The "Logic" of a creationist....'? To be less general of course. I have no problem with your accusations against JP as you have assessed.

SLP:
It, too, says nothing of the numbers of mutations required. John Paul:The links I posted were NOT supposed to discuss mutations. The context of the discussion was whether or not the alleged ancestor (10 million years ago) had any of the adaptations observed only in modern humans- language, speech & upright posture. What the links do is to show we have no idea how these adaptations came to be. We only assume they evolved because we assume humans did evolve from some primitive ancestor. The only one with faulty logic is you and your buddy Robert. Again. YOU don't get to choose the mutations. Robert's "test" was faulty. Excuse me for exposing it. It is also not my problem that you and your ilk can't understand logical reasoning. ------------------John Paul [This message has been edited by John Paul, 08-12-2002]

Oh - and who said anything about 'choosing' the mutations? More of that 20/20 hindsight logic from Joey? The ones that account for human evolution form an ape-like ancestor are the ones that are presumed to have occurred. We are 'choosing' the ones that happened.

dear JP,
You state:"It, too, says nothing of the numbers of mutations required." Actually it just depends on the gene or DNA region of the primates one studies. There are genes that are (almost) identical between chimp and human, but there are also genes that are very, very distinct (indicating a directed mechanism). If you have a careful look at the chromosomes and DNA sequences of both species it is highly questionable whether a random mechanism is involved. One might as well assume creation. Peter

dear SLPx,
I will look into my weird-stuff-literature and I will let you know what gene I referred to (it was a very recent Nature or Science article). Next, we can calculate a bit on it and find out what mechanism is involved. I go for a non-random/directed mechanism. I presume you go for randomness and selection. best wishes,Peter

dear SLPx,
The article I refered to can be found in:Nature 2001 Oct 4;413(6855),p514-9. Let's have a carefull look at this gene family and whether a random non-directed mechanism can hold. Positive selection of a gene family during the emergence of humans and African apes, by johnson ME et al. Gene duplication followed by adaptive evolution is one of the primary forces for the emergence of new gene function. Here we describe the recent proliferation, transposition and selection of a 20-kilobase (kb) duplicated segment throughout 15 Mb of the short arm of human chromosome 16. The dispersal of this segment was accompanied by considerable variation in chromosomal-map location and copy number among hominoid species. In humans, we identified a gene family (morpheus) within the duplicated segment. Comparison of putative protein-encoding exons revealed the most extreme case of positive selection among hominoids. The major episode of enhanced amino-acid replacement occurred after the separation of human and great-ape lineages from the orangutan. Positive selection continued to alter amino-acid composition after the divergence of human and chimpanzee lineages. The rapidity and bias for amino-acid-altering nucleotide changes suggest adaptive evolution of the morpheus gene family during the emergence of humans and African apes. Moreover, some genes emerge and evolve very rapidly, generating copies that bear little similarity to their ancestral precursors. Consequently, a small fraction of human genes may not possess discernible orthologues within the genomes of model organisms. For your information:PMID: 11586358 [PubMed - indexed for MEDLINE] I recommend anyone who wants to participate in the discussion to read the article very carefully. I will soon send in my comments that demontrate where it clashes with NDT. For now, focus your attention to the latter two sentences of the abstract. Will this paper provide a cover for future genes that will not be found in the great apes, but will be present in the human genome? Best wishes, Peter [This message has been edited by peter borger, 08-15-2002]

Peter B: I, for one, will be absolutely fascinated to see your comments inre how variable rates in the evolution of morpheus falsifies the NDT. Especially since I just finished (before reading this thread) posting another "rapid evolution" reference on a D. melanogaster gene (Sdic). Obviously, the occurance is well-known and documented.
BTW: Thanks for providing another example that refutes Tranquility Base's contention about the impossibility of novel gene evolution. The part in your abstract concerning "Moreover, some genes emerge and evolve very rapidly, generating copies that bear little similarity to their ancestral precursors." quite nicely adds additional weight to my rebuttal of HIS assertion. (ID, attempting to trump evolution, instead trumps YEC. Whee.) [edited for typo] [This message has been edited by Quetzal, 08-15-2002]

Scott:Oh - and who said anything about 'choosing' the mutations? John Paul:You don’t get to choose the mutations. In this method the criterion for selection is a long-range goal when in direct contrast the criterion for natural selection must be short-range. If we have millions of base pairs that are different, less than 2000 key genes, and some 225,000 coding positions that are different, that would tell me that more mutations took place than 1667. That said the ONLY way to get a human from some primitive ancestor in 1667 mutations would be to choose them. And by assuming common descent we are assuming that mutations can do the trick. Any evidence to support that assumption? ------------------John Paul [This message has been edited by John Paul, 08-15-2002]

Q:
BTW: Thanks for providing another example that refutes Tranquility Base's contention about the impossibility of novel gene evolution. John Paul:Taken in context Creationists state that is impossible only in the random mutation scenario. Directed mutations- by the designed genome's built-in ability to sense and react to environmental pressures- refutes the ToE. Actually it wouldn't. The ToE would just be re-written to accomodate directed mutations. ------------------John Paul
