| Theory of Evolution |
It is not a strategy calculated to induce confidence in the scientific method.
A paper published recently in the Proceedings of the Biological Society of Washington concluded that the events taking place during the Cambrian era could best be understood in terms of an intelligent design – hardly a position unknown in the history of Western science. The paper was, of course, peer-reviewed by three prominent evolutionary biologists.
Wise men attend to the publication of every one of the society’s papers, but in this case, the editors were given to understand that they had done a bad thing. Their indecent capitulation followed at once. Publication of the paper, they confessed, was a mistake. And peer review? The heck with it.
“If scientists do not oppose anti-evolutionism,” remarked Eugenie Scott, executive director of the National Council for Science Education, “it will reach more people with the mistaken idea that evolution is scientifically weak.”
Scott’s understanding of “opposition” had nothing to do with reasoned discussion. It had nothing to do with reason at all. Discussing the issue was out of the question.
Her advice to her colleagues was considerably more to the point: “Avoid debates.” Everyone had better shut up. But in this country, at least, no one is ever going to shut up, the more so since the case against Darwin’s theory retains an almost lunatic vitality.
Look: The suggestion that Darwin’s theory of evolution is like theories in the serious sciences – for example, quantum electrodynamics – is grotesque. Quantum electrodynamics is accurate to 13 unyielding decimal places. Darwin’s theory makes no tight quantitative predictions all.
Look: Field studies attempting to measure natural selection inevitably report weak to non-existent selection effects.
Look: Darwin’s theory is open at one end since there is no plausible account for the origins of life.
Look: The astonishing and irreducible complexity of various cellular structures has not yet successfully been described, let alone explained.
Look: A great many species enter the fossil record trailing no obvious ancestors and depart for Valhalla leaving no obvious descendents.
Look: Where attempts to replicate Darwinian evolution on the computer have been successful, they have not used classical Darwinian principles. Where they have used such principles, they have not been successful.
Look: Tens of thousands of fruit flies have come and gone in laboratory experiments, and every last one of them has remained a fruit fly to the end, all efforts to see the miracle of speciation unavailing.
Look: The remarkable similarity in the genome of a great many organisms suggests that there is, at bottom, only one living system. But how then to account for the astonishing differences between human beings and their near relatives, differences that remain obvious to anyone who has visited a zoo?
But look again: If the differences between organisms are scientifically more interesting than their genomic similarities, of what use is Darwin’s theory since its otherwise mysterious operations take place by genetic variations?
These are hardly trivial questions. Each suggests a dozen others. These are hardly circumstances that do much to support the view that there are “no valid criticisms of Darwin’s theory,” as so many recent editorials have suggested.
Serious biologists quite understand all this. They rather regard Darwin’s theory as an elderly uncle invited to a family dinner. The old boy has no hair, he has no teeth, he is hard of hearing and he often drools. Addressing even senior members at table as “sonny,” he is inordinately eager to tell the same story over and over again. But he’s family. What can you do?
David Berlinski received his PhD in philosophy from Princeton University and was later a postdoctoral fellow in mathematics and molecular biology at Columbia University. He is a senior fellow at the Discovery Institute in Seattle.
