THEY WOULDN'T EVEN HAVE 13% WITHOUT THE COERCION THE MONOPOLY PROVIDES:
An intelligent approach to intelligent design (Michael Balter, January 31, 2007, International Herald Tribune)
Given the theory of evolution's monopoly in the classroom, one might think that it has gained a steady stream of converts over the years. But a recent poll taken for the BBC found that the British public was split on the issue: Only 48 percent of respondents thought evolution best explained the development of life on earth, while 22 percent chose creationism, 17 percent intelligent design, and the rest said they did not know.As depressing as those figures might be to scientists, they are pretty good compared to the results of similar surveys in the United States. A Gallup poll in November 2004 found that only 13 percent of respondents thought that God had no part in the evolution or creation of human beings, while 45 percent said they believed that God had created humans in their present form within the last 10,000 years or so.
To be sure, this chronic skepticism about evolutionary theory reflects the continuing strong influence of religion. Yet it also implies that scientists have not been persuasive enough, even when buttressed by strong scientific evidence that natural selection alone can account for life's complexity.
Could it be that the theory of evolution's monopoly in the classroom has backfired?
With all due regard to Mr. Balter, you have to laugh at the notion that religion is the only basis for continuing skepticism about Darwinism. Heck, catch them with their guard down and even the most vocal of the adherents don't really believe natural selection suffices.
And, of course, the honest ones are beyong redemption, Why Do We Invoke Darwin?: Evolutionary theory contributes little to experimental biology (Philip S. Skell, 8/29/05, The Scientist)
Darwin's theory of evolution offers a sweeping explanation of the history of life, from the earliest microscopic organisms billions of years ago to all the plants and animals around us today. Much of the evidence that might have established the theory on an unshakable empirical foundation, however, remains lost in the distant past. For instance, Darwin hoped we would discover transitional precursors to the animal forms that appear abruptly in the Cambrian strata. Since then we have found many ancient fossils - even exquisitely preserved soft-bodied creatures - but none are credible ancestors to the Cambrian animals.Despite this and other difficulties, the modern form of Darwin's theory has been raised to its present high status because it's said to be the cornerstone of modern experimental biology. But is that correct? "While the great majority of biologists would probably agree with Theodosius Dobzhansky's dictum that 'nothing in biology makes sense except in the light of evolution,' most can conduct their work quite happily without particular reference to evolutionary ideas," A.S. Wilkins, editor of the journal BioEssays, wrote in 2000. "Evolution would appear to be the indispensable unifying idea and, at the same time, a highly superfluous one." [...]
Darwinian evolution - whatever its other virtues - does not provide a fruitful heuristic in experimental biology. This becomes especially clear when we compare it with a heuristic framework such as the atomic model, which opens up structural chemistry and leads to advances in the synthesis of a multitude of new molecules of practical benefit. None of this demonstrates that Darwinism is false. It does, however, mean that the claim that it is the cornerstone of modern experimental biology will be met with quiet skepticism from a growing number of scientists in fields where theories actually do serve as cornerstones for tangible breakthroughs.
-The Evolution of Ernst: Interview with Ernst Mayr: The preeminent biologist, who just turned 100, reflects on his prolific career and the history, philosophy and future of his field On July 5, renowned evolutionary biologist Ernst Mayr celebrated his 100th birthday. He also recently finished writing his 25th book, What Makes Biology Unique?: Considerations on the Autonomy of a Scientific Discipline [Cambridge University Press, in press]. A symposium in Mayr's honor was held at Harvard University on May 10. Scientific American editor and columnist Steve Mirsky attended the symposium and wrote about it for the upcoming August issue. On May 15, Mirsky, Brazilian journalist Claudio Angelo and Angelo's colleague Marcelo Leite visited Mayr at his apartment in Bedford, Mass. (Scientific American, 7/06/04)
Claudio Angelo: What is the book about?Posted by Orrin Judd at January 31, 2007 9:21 PMErnst Mayr: What the book is about. (Laughs.) Primarily to show, and you will think that this doesn't need showing, but lots of people would disagree with you. To show that biology is an autonomous science and should not be mixed up with physics. That's my message. And I show it in about 12 chapters. And, as another fact, when people ask me what is really your field, and 50 years or 60 years ago, without hesitation I would have said I'm an ornithologist. Forty years ago I would have said, I'm an evolutionist. And a little later I would still say I'm an evolutionist, but I would also say I'm an historian of biology. And the last 20 years, I love to answer, I'm a philosopher of biology. And, as a matter of fact, and that is perhaps something I can brag about, I have gotten honorary degrees for my work in ornithology from two universities, in evolution, in systematics, in history of biology and in philosophy of biology. Two honorary degrees from philosophy departments.
Steve Mirsky: And the philosophical basis for physics versus biology is what you examine in the book?
EM: I show first in the first chapter and in some chapters that follow later on, I show that biology is as serious, honest, legitimate a science as the physical sciences. All the occult stuff that used to be mixed in with philosophy of biology, like vitalism and teleology-Kant after all, when he wanted to describe biology, he put it all on teleology, just to give an example-all this sort of funny business I show is out. Biology has exactly the same hard-nosed basis as the physical sciences, consisting of the natural laws. The natural laws apply to biology just as much as they do to the physical sciences. But the people who compare the two, or who, like some philosophers, put in biology with physical sciences, they leave out a lot of things. And the minute you include those, you can see clearly that biology is not the same sort of thing as the physical sciences. And I cannot give a long lecture now on that subject, that's what the book is for.
I'll give you an example. In principle, biology differs from the physical sciences in that in the physical sciences, all theories, I don't know exceptions so I think it's probably a safe statement, all theories are based somehow or other on natural laws. In biology, as several other people have shown, and I totally agree with them, there are no natural laws in biology corresponding to the natural laws of the physical sciences.
Now then you can say, how can you have theories in biology if you don't have laws on which to base them? Well, in biology your theories are based on something else. They're based on concepts. Like the concept of natural selection forms the basis of, practically the most important basis of, evolutionary biology. You go to ecology and you get concepts like competition or resources, ecology is just full of concepts. And those concepts are the basis of all the theories in ecology. Not the physical laws, they're not the basis. They are of course ultimately the basis, but not directly, of ecology. And so on and so forth. And so that's what I do in this book. I show that the theoretical basis, you might call it, or I prefer to call it the philosophy of biology, has a totally different basis than the theories of physics.
Alright, I'll bite.
First, the tone of the first article you quote is regrettable. There is no a priori reason why scientists should be "depressed" to find that only 13 percent of polled Americans believe that God played no part in the origins of human beings. If this figure truly indicated a rejection of evolutionary theory, that would be disappointing, but as many scientists have tried to communicate, the conflicts between evolution and a purposeful Creator are not insurmountable. There is a qualitative difference between teaching evolution and advocating atheism.
Second, it is probably a good thing that Skell focuses on the Cambrian expansion for his transitional fossil argument, given that this remains the only real evolutionary mystery left, and that transitional fossils for the origins of all the other major divergences with which we might be concerned (vertebrates, birds, mammals, primates) are well known.
I'd even take issue with his notion that Darwinian evolution has made no contribution to experimental science. It has historically been used to make specific predictions about the sorts of genes and proteins one might find in one organism, based on apparent relationships to others. And the principles are used in the design of new therapies (SELEX and whatnot) rather commonly these days.
The rest of it is just pointing out that biology isn't physics. Big deal. George Gamow and other physicists used to make biologists quake in their shoes with cheap arguments like that, but that was back when biology, and in particular evolutionary biology, was still an infant science. Speciation is now a laboratory science, and the field in general has a large enough pool of observation and experimentation to stake a claim to more than just an alternative historical narrative.
Posted by: M. at February 1, 2007 8:16 AMOf course, even most Darwinists are either Creationist or IDers. The 13% is much lower in reality. As David Stove points out, they can't even explain Darwinism without resort to ID metaphors. Note that even your own bit about purposeful Darwinism guts the theory.
And the fact that Darwinism has no real world applications nor scientific backing is embarrassing, but hardly fatal. It just makes the theory a philosophy rather than a science, as Mayr is unbashful about conceding.
The point isn't that they should be depressed but that they've failed because they were wrong. No shame in that. They join the Marxists and Freudians on the 19th century trash heap.
Posted by: oj at February 1, 2007 8:21 AMI wonder that Paul Johnson didn't give Darwin a chapter in The Intellectuals. He only gets a couple of words in the chapter on Marx.

A great post on evolution at Brothers Judd: THEY WOULDN'T EVEN HAVE 13% WITHOUT THE COERCION THE MONOPOLY PROVIDES. Brothers Judd often takes potshots at evolution, but this post is more substantive. They quote an article "Why Do We Evoke Darwin?" from a magazine called The Scientist: Magazine of the Life Sciences:
Darwin's theory of evolution offers a sweeping explanation of the history of life, from the earliest microscopic organisms billions of years ago to all the plants and animals around us today. Much of the evidence that might have established the theory on an unshakable empirical foundation, however, remains lost in the distant past. For instance, Darwin hoped we would discover transitional precursors to the animal forms that appear abruptly in the Cambrian strata. Since then we have found many ancient fossils - even exquisitely preserved soft-bodied creatures - but none are credible ancestors to the Cambrian animals.
Despite this and other difficulties, the modern form of Darwin's theory has been raised to its present high status because it's said to be the cornerstone of modern experimental biology. But is that correct? "While the great majority of biologists would probably agree with Theodosius Dobzhansky's dictum that 'nothing in biology makes sense except in the light of evolution,' most can conduct their work quite happily without particular reference to evolutionary ideas," A.S. Wilkins, editor of the journal BioEssays, wrote in 2000.[1] "Evolution would appear to be the indispensable unifying idea and, at the same time, a highly superfluous one."
I would tend to agree. Certainly, my own research with antibiotics during World War II received no guidance from insights provided by Darwinian evolution. Nor did Alexander Fleming's discovery of bacterial inhibition by penicillin. I recently asked more than 70 eminent researchers if they would have done their work differently if they had thought Darwin's theory was wrong. The responses were all the same: No.
I also examined the outstanding biodiscoveries of the past century: the discovery of the double helix; the characterization of the ribosome; the mapping of genomes; research on medications and drug reactions; improvements in food production and sanitation; the development of new surgeries; and others. I even queried biologists working in areas where one would expect the Darwinian paradigm to have most benefited research, such as the emergence of resistance to antibiotics and pesticides. Here, as elsewhere, I found that Darwin's theory had provided no discernible guidance, but was brought in, after the breakthroughs, as an interesting narrative gloss.
In the peer-reviewed literature, the word "evolution" often occurs as a sort of coda to academic papers in experimental biology. Is the term integral or superfluous to the substance of these papers? To find out, I substituted for "evolution" some other word - "Buddhism," "Aztec cosmology," or even "creationism." I found that the substitution never touched the paper's core. This did not surprise me. From my conversations with leading researchers it had became clear that modern experimental biology gains its strength from the availability of new instruments and methodologies, not from an immersion in historical biology.
The genuine scientific contribution of Darwinian thinking can be separated from Darwinist ideology/creation-mythology by substituting the "Darwinian theory of evolution" with a "Darwinian theory of imperfect ecosystemic homeostasis."
Homeostasis is a property of living organisms, namely that the atoms of which they are physically comprised at any given time cycle in and out of them, yet the form of the organism maintains a high degree of continuity. As organisms exhibit homeostasis with respect to the atoms that comprise them, so ecosystems exhibit homeostasis with respect to the organisms that comprise them: trees, birds, insects, mammals are born, grow, and die, but the forest remains. This may be called ecosystemic homeostasis.
The Darwinian theory sheds light, both on (a) why the forest is able to maintain homeostasis, and (b) why the homeostasis is imperfect, i.e., the forest will not stay exactly the same forever (even putting to one side exogenous climatic or geological changes). The forest maintains homeostasis because organisms are adapted to their environments and achieve a sort of equilibrium; but it can change over time because the Mendelian genetics that underlies the forms of organisms, combined with natural selection and (very rarely) advantageous mutations, can enable organisms to upgrade, or to find new niches, creating ripple effects throughout the ecosystem. Experimental evidence that this kind of evolution can occur is not really needed; once the truths of Mendelian genetics (plus the possibility of mutation) are established, logic alone is enough to show that evolution is at least a possibility, though perhaps a vanishingly rare one. We don't know, based on logic alone, whether it has played a significant role in natural history or not. Perhaps fossil evidence suggests that it has played at least some role. (I'm not a paleontologist.)
That's as far as science, properly understood, can go. The unwarranted and superfluous further claim that this is how all life originated is our civilization's reigning creation-myth but is not science. We don't know how all life was created, and we probably never will. The evidence is just too scanty.
