THE 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.

The 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.

NOTA IMPERTINENTE DESTE BLOGGER:

Quando afirmo neste blog que a Síntese Evolutiva Moderna, apesar de ser a teoria que aparece como 'ortodoxia' em nossos livros didáticos de Biologia do ensino médio, é uma teoria cientificamente morta (Stephen Jay Gould afirmou isso em 1980), a Galera dos meninos e meninas de Darwin diz que eu não entendo o que é ciência e como que ela 'evolui' à luz de novos conhecimentos. Será?

Gente, são mais de 3 décadas engabelando a educação de nossa juventude. Eu tinha me esquecido da convenção que houve em 1966 no Wistar Institute, onde matemáticos, biólogos e outros cientistas evolucionistas se reuniram. Conclusão dos matemáticos: Darwin não fecha as contas epistêmicas. A nova teoria geral da evolução - a SÍNTESE EVOLUTIVA AMPLIADA vai chegar com quase 45 anos de atraso.

É mole? 45 anos para reconhecer que Darwin não fecha as contas no contexto de justificação teórica? Desde 1859 que não fecha as contas: seu livro Origem das Espécies passou por 6 edições, 5 revistas.

Alô Exmo. Sr. Ministro da Educação: o MEC/SEMTEC/PNLEM não pode mais continuar aprovando livros didáticos com fraudes e distorções de evidências a favor do fato, Fato, FATO da evolução. 171 já vale na Akademia? V. Excia. vai pactuar com o descompasso com a verdade científica desses autores desatualizados por conveniência ideológica da Nomenklatura científica?

Quando a questão é Darwin, é tutti cosa nostra, capice?
