Thinkquote of the day: The problem with the fossil record

Of course, if the fossil record does not fit the theory, it is always possible to adjust the theory to fit the record. In science, an enterprising theoretician has several degrees of freedom within which to maneuver before the referee reaches ten and the final bell comes to clang. Steven [sic] Jay Gould, who was trained as a paleontologist, surveyed the fossil evidence early in the 1970s and came to the obvious conclusion that either the theory or the evidence must go. What went, on his scheme of things, was the neo Darwinian orthodoxy by which species change into different species by means of an endless series of infinitesimal changes, continuously, like the flow of syrup. Instead, Gould argued, biological change must have been discontinuous, with vast changes taking place at once. Such was his model of punctuated equilibria. It fits the fossil record far better (if it makes sense, even, to talk of scientific fit here), but the model achieves faithfulness to the facts only by chucking out the chief concepts of the Darwinian theory itself, and while paleontologists have been glad to have had Gould's company, evolutionary theorists have looked over what he has written with the cool, slitted, appraising glance of a butcher eyeing a sheep. (David Berlinski, "The Evidence for Evolution," in Black Mischief: Language, Life, Logic, Luck , Harcourt Brace Jovanovich: Boston MA, Second Edition, 1988, pp.30-302)

In By Design or by Chance?, I address Gould's attempt to dissent from Darwinism based on the fossil evidence and the resulting posthumous attacks on him. There was also a curious incident last fall when a friend of Gould's came forward to say that he had never been a Darwinist. I think the friend was likely right, but denying the creation story of materialism was and is a risky business in the society in which Gould lived.

To Mr. Anonymous: I'm not psychic, so if you won't tell me who you are, I can't guess and don't care. To Mr. Nude World (URL): If you can't be bothered telling site visitors why they should go on to your fave site next, why should I post your comment? They're all busy people, like you. To Mr. Rudeby International and Mr. Pottymouth: I also have a tendency to delete comments that are merely offensive. Go be offensive to someone who can smack you a good one upside the head.

To Mr. Righteous but Wrong: I don't publish comments that contain known or probable factual errors. There's already enough widely repeated misinformation out there, and if you don't have the time to do your homework, I don't either. To those who write to announce that at death I will either 1) disintegrate into nothingness or 2) go to Hell by a fast post, please pester someone else. I am a Catholic in communion with the Church and haven't the time for either village atheism or aimless Jesus-hollering.
