Genetic Changes In Mice 'Question Evolution Speed'

Genetic changes in mice 'question evolution speed'

A species of mouse has evolved dramatically in just 150 years, showing genetic change can occur much faster than was thought possible.

The discovery was made by accident by two American biologists studying the genetic make-up of a common wild mouse in Chicago.

Dr Dennis Nyberg and Dr Oliver Pergams, both from the University of Illinois at Chicago, analysed DNA samples from 56 museum specimens of the white-footed mouse dating back to 1855, and 52 wild mice captured from local forests and parks.

They found startling genetic differences between the 19th century and modern mice.

Only one of the present-day mice had DNA that matched that of mice collected before 1950.

While fast evolutionary change has been seen in fruit flies, such rapid evolution in a mammal has not been reported before.

The scientists, whose findings appear in the journal Nature, believe humans may have been partly responsible for the "new" mice.

"Settlers may have brought in mice with the favourable gene that were able to out-compete mice with the native variant," said Dr Pergams.

Would you please take a moment to explain the difference between a hypothesis and a theory to our deluded friend here.

I can only take so much of that tagline before I die laughing.

'You speak of finding a flaw in my hypothesis,' Darwin rallied him, `& this shows you do not understand its nature. It is a mere rag of an hypothesis with as many flaw & holes as sound parts.' But `I can carry in it my fruit to market for a short distance over a gentle road; not I fear that you will give the poor rag such a devil of a shake that it will fall all to atoms; & a poor rag is better than nothing to carry one's fruit to market in.'

Here he continued his half-begging, self-mocking letters, eliciting information while converting the donor - softening up breeders to obtain gulliver runts (pigeons) and softening up old presbyterians like Asa Gray at the Harvard herbarium: 'It is extremely kind of you to say that my letters have not bored you very much, & it is almost incredible to me, for I am quite conscious that my speculations run beyond the bounds of true science.' Or, at least, true science as then was.

OK, I have got to hear this, what does that WHOLE quote taken in context mean to you.

Really, what is Darwin saying, and why is he saying it, please share with me your views on it.

I want my wife to hear me laughing all the way downstairs.

Go ahead, tell me what and why he is saying what he is saying.

THE 1966 PHILADELPHIA MEETING
It was not until the 1960s that the neo-Darwinists really began fighting among themselves in earnest. At Wistar, evolutionary theory was destroyed by mathematical facts.

"The ascription of all changes in form to chance has long caused raised eyebrows. Let us not dally with the doubts of nineteenth-century critics, however; for the issue subsided. But it raised its ugly head again in a fairly dramatic form in 1967, when a handful of mathematicians and biologists were chattering over a picnic lunch organized by the physicist, Victor Weisskopf, who is a professor at Massachusetts Institute of Technology (MIT) and one of the original Los Alamos atomic bomb group, at his house in Geneva. `A rather weird discussion' took place. The subject was evolution by natural selection. The mathematicians were stunned by the optimism of the evolutionists about what could be achieved by chance. So wide was the rift that they decided to organize a conference, which was called Mathematical Challenges to the Neo-Darwinian Theory of Evolution. The conference was chaired by Sir Peter Medawar, whose work on graft rejection won him a Noble prize and who, at the time, was director of the Medical Research Council's laboratories in North London. Not, you will understand, the kind of man to speak wildly or without careful thought. In opening the meeting, he said: `The immediate cause of this conference is a pretty widespread sense of dissatisfaction about what has come to be thought of as the accepted evolutionary theory in the English-speaking world, the so-called neo-Darwinian theory. This dissatisfaction has been expressed from several quarters."—*G.R. Taylor, Great Evolution Mystery (1983), p. 4.

A milestone meeting was the Wistar Institute Symposium held in Philadelphia in April 1966. The chairman, *Sir Peter Medawar, made the following opening remark:

"The immediate cause of this conference is a pretty widespread sense of dissatisfaction about what has come to be thought as the accepted evolutionary theory in the English-speaking world, the so-called neo-Darwinian theory . . These objections to current neo-Darwinian theory are very widely held among biologists generally; and we must on no account, I think, make light of them."—*Peter Medawar, remarks by the chairman, *Paul Moorhead and *Martin Kaplan (ed.), Mathematical Challenges to the Neo-Darwinian Interpretation of Evolution, Wistar Institute Monograph No. 5.

A number of mathematicians, familiar with the biological problems, spoke at that 1966 Wistar Institute. They clearly refuted neo-Darwinianism in several areas, and showed that its "fitness" and "adaptation" theories were tautologous—little more than circular reasoning. In contrast, some of the biologists who spoke at the convention could not see the light. They understood bugs and turtles, but could grasp neither the mathematical impossibilities of evolutionary theory nor the broad picture of how thoroughly defunct evolution really is.

For example, one of the mathematicians, *Murray Eden of MIT, explained that life could not begin by the "random selection," which is the basic pillar of evolutionary teaching. Yet he said that if randomness is set aside, then only "design" would remain—and that would require purposive planning by an Intelligence.

*C.H. Waddington, a prominent British evolutionist, scathingly attacked neo-Darwinism, maintaining that all it proved was that plants and animals could have offspring!

The 1966 Wistar convention was the result of a meeting of mathematicians and biologists the year before in Switzerland. Mathematical doubts about Darwinian theory had been raised; and, at the end of several hours of heated discussion, it was agreed that a meeting be held the next year to more fully air the problems. *Dr. Martin Kaplan then set to work to lay plans for the 1966 Wistar Institute.

It was the development of tremendously powerful digital computers that sparked the controversy. At last mathematicians were able to work out the probability of evolution ever having occurred. They discovered that, mathematically, life would neither have begun nor evolved by random action.

For four days the Wistar convention continued, during which a key lecture was delivered by *M.P. Schutzenberger, a computer scientist, who explained that computers are large enough now to totally work out the mathematical probabilities of evolutionary theory—and they demonstrate that it is really fiction.

*Murray Eden showed that it would be impossible for even a single ordered pair of genes to be produced by DNA mutations in the bacteria, E. coli,—with 5 billion years in which to produce it! His estimate was based on 5 trillion tons of the bacteria covering the planet to a depth of nearly an inch during that 5 billion years. He then explained that the genes of E. coli contain over a trillion (1012) bits of data. That is the number 10 followed by 12 zeros. *Eden then showed the mathematical impossibility of protein forming by chance. He also reported on his extensive investigations into genetic data on hemoglobin (red blood cells).

Hemoglobin has two chains, called alpha and beta. A minimum of 120 mutations would be required to convert alpha to beta. At least 34 of those changes require changeovers in 2 or 3 nucleotides. Yet, *Eden pointed out that, if a single nucleotide change occurs through mutation, the result ruins the blood and kills the organism!

*George Wald stood up and explained that he had done extensive research on hemoglobin also,—and discovered that if just ONE mutational change of any kind was made in it, the hemoglobin would not function properly. For example, the change of one amino acid out of 287 in hemoglobin causes sickle-cell anemia. A glutamic acid unit has been changed to a valine unit—and, as a result, 25% of those suffering with this anemia die.

For more information on the 1966 Wistar Institute, we refer you to the book quoted above, by *Moorehead and *Kaplan. For much more on mathematical problems confronting evolutionary theory. (See DNA and Cells).

The 1969 Alpbach Meeting
A follow-up meeting was held in 1969 at Alpbach, but it only resulted in fruitless discussions in defense of evolution, angry words by some, desperation by others desiring some kind of "evolutionary" solution that scientists could ably defend, and additional presentations of evidence that evolutionary theory was unscientific. Although it was an important meeting, little space was given to it in the public press.

"Throughout the past century there has always existed a significant minority of first-rate biologists who have never been able to bring themselves to accept the validity of Darwinian claims. In fact, the number of biologists who have expressed some degree of disillusionment is practically endless. When Arthur Koestler organized the Alpbach Symposium, in 1969, called `Beyond Reductionism,' for the express purpose of bringing together biologists critical of orthodox Darwinism he was able to include in the list of participants many authorities of world stature, such as Swedish neurobiologist, Holgar Hyden; zoologists, Paul Weiss and W.H. Thorpe; linguist, David McNeil; and child psychologist, Jean Piaget. Koestler had this to say in his opening remarks: `. . invitations were confined to personalities in academic life, with undisputed authority in their respective fields, who nevertheless share that holy discontent.

"At the Wistar Institute Symposium in 1966, which brought together mathematicians and biologists of impeccable academic credentials, Sir Peter Medawar acknowledged in his introductory address the existence of a widespread feeling of skepticism over the role of chance in evolution, a feeling in his own words that: `. . something is missing from orthodox theory.' "—*Michael Denton, Evolution: A Theory in Crisis (1985), pp. 327-328.

THE 1980 NEW YORK MEETING
For decades, men had to silently accept evolutionary theory in order to graduate with a doctorate and enter a field of science. Everywhere they turned in their chosen field, they see evidence of creation, not evolution. An ever-increasing explosion of knowledge in the sciences only added to the massive weight of evidence in favor of creation science. But, at last, careful researchers were beginning to openly scoff at evolutionary theory in professional journals. Leading paleontologists, such as *Gould and Stanley, were brazenly flaunting the foolishness of Darwin's legacy; but, unfortunately they were substituting strange new fairy tales that were utterly opposed to reality, common sense, genetics, mutational studies, or mathematical probabilities. Something had to be done.

In October 1980, the world's leading evolutionists met in Chicago in a special Evolution Conference.

"The central question of the Chicago conferences was whether the mechanisms underlying microevolution can be extrapolated to explain the phenomena of macroevolution."—*Roger Lewin, "Evolutionary Theory Under Fire," in Science, November 21, 1980.

"Microevolution" is change within a species, but this is adaptation and not evolution, as most experts will admit. "Macroevolution" is change between species, and must always lie at the heart of evolutionary theory. Without macroevolution, evolution does not occur. At the 1980 Chicago meeting:

"In October 1980, . . a conference was held in Chicago on one of the hottest issues in evolutionary studies. The respected magazine, Science, organ of the American Association of the Advancement of Science, called it `a historic conference' which `challenges the four-decade long dominance of the Modern Synthesis.' `We all went home with our heads spinning,' said one participant. `Clashes of personality and academic sniping created palpable tension in an atmosphere that was fraught with genuine intellectual ferment,' Science reported."—*G.R. Taylor, Great Evolution Mystery (1983), p. 55.

Open attacks were hurled at evolutionary theory, and men desperate for solutions sought for answers.

"Feuds concerning the theory of evolution exploded . . Entrenched positions, for and against, were established in high places, and insults lobbed like mortar bombs from either side."—*Francis Hitching, The Neck of the Giraffe (1982), p. 12.

Yes, arguments took place, even some shouting. The conclusion of the majority was that there is no evidence of evolution, and we have no way of demonstrating that it is occurring now or has ever occurred.

"At the risk of doing violence to the positions of some of the people at the meeting, the answer can be given as a clear No."—*Roger Lewin, The Neck of the Giraffe (1982), p. 12.

*Newsweek for November 3, 1980, carried an article on the Chicago meeting. You may wish to read it for yourself. The large majority of evolutionists at the conference agreed that the neo-Darwinian mechanism of mutation and natural selection could no longer be regarded by professionals as scientifically valid or tenable. Neither the origin nor the diversity of living creatures could be explained by evolutionary theory.

A year later, *Robert Jastrow, a leading scientist wrote:

"To their chagrin [scientists] have no clear-cut answer, because chemists have never succeeded in reproducing nature's experiments on the creation of life out of nonliving matter. Scientists do not know how that happened . . Scientists have no proof that life was not the result of an act of creation."—*Robert Jastrow, The Enchanted Loom: Mind in the Universe (1981), p. 19.

Of the scientists attending that meeting, some in desperation decided that the only solution was to join *Gould and *Stanley in viewing hopeful monsters as the means by which species change occurred! To coin a phrase that might be worthy of Shakespeare: "Ah, desperation, thou hast made men mad."

The 1980 meeting was held in Chicago's Field Museum and was attended by 160 of the world's top paleontologists, anatomists, evolutionary geneticists, and developmental biologists.

"[Evolution] is undergoing its broadest and deepest revolution in nearly 50 years . . Exactly how evolution happened is now a matter of great controversy among biologists . . No clear resolution of the controversies was in sight [at the meeting]."—*Boyce Rensberger, "Macroevolution Theory Stirs Hottest Debate Since Darwin," in The Riverside (California) Enterprise, p. E9; *Roger Lewin, "Evolutionary Theory under Fire," Science, November 21, 1980, pp. 883-887.

It was decided that no record would be kept of the sessions, in order not to give ammunition to the creationists. The rapid accumulation of evidence against evolutionary theory had brought a crisis of such proportions that most of those in attendance decided to repudiate a cardinal Darwinian doctrine; they agreed that small changes from generation to generation within a species could never accumulate to produce a new species.

In its place, the Alice-in-Wonderland theory of "punctuated equilibria" was given prominence. This view teaches that sudden massive mutations produced "hopeful monsters"—and made all our modern species. It was at the 1980 meeting that the majority of leading scientists present decided in desperation to adopt the basic "hopeful monster" theory of *Goldschmidt, *Stanley, and *Gould.

Men act as if they are chained to a cart and must go wherever it carries them. They dare not get off of it, for to do so is admit a terrible fact which they do not wish to consider.

"According to an article in Newsweek (November 3, 1980), at a conference in mid-October at Chicago's Field Museum of Natural History, the majority of 160 of the world's top paleontologists, anatomists, evolutionary geneticists, and developmental biologists agreed to abandon Darwinian evolution in favor of punctuated equilibria, otherwise known as the hopeful monster theory.

"Apparently, Darwin's theory had become indefensible to them, citing particularly the absence of intermediate fossils as the conflicting fact. The hopeful monster theory is a retreat to what appears to be reliable geological evidence, namely, the general stringing-out of fossils from `simple' to `complex' in the rock strata."—Randall Hedtke, "Asa Gray Vindicated," in Creation Research Society Quarterly, June 1981, p. 74.

1984 CAMBRIDGE MEETING
The following year, still another important meeting of evolutionists was held. At this meeting, held at the American Museum of Natural History in New York City, *Colin Patterson, senior paleontologist at the British Museum of Natural History, in a paper that he presented to the assembly, declared before his peers that evolution was "positively anti-knowledge," and added that "all my life I had been duped into taking evolution as revealed truth."

The same year another scientist wrote this:

"An increasing number of scientists, most particularly a growing number of evolutionists . . argue that Darwinian evolutionary theory is no genuine scientific theory at all . . Many of the critics have the highest intellectual credentials."—*Michael Ruse, "Darwin's Theory: An Exercise in Science," in New Scientist, June 25, 1981, p. 828.

Commenting on the crisis that had come to the evolutionary camp, *Niles Eldredge, head of the Department of Paleontology at the American Museum of Natural History, later wrote this:

"The doubt that has infiltrated the previously smug confident certitude of evolutionary biology's last twenty years has inflamed passions . . There has been a total lack of agreement even within the warring camps . . Things are really in an uproar these days . . Sometimes it seems as though there are as many variations on each [evolutionary] theme as there are individual biologists."—*Niles Eldredge, "Evolutionary Housecleaning," in Natural History, February 1982, pp. 78, 81.
