What Darwin didn't get wrong

Last October I reviewed three books about evolution: Neil Shubin's Your Inner Fish, Jerry Coyne's Why Evolution is True, and Richard Dawkins's The Greatest Show on Earth: The Evidence for Evolution. It was a long review, but pretty good, I think.

There's another long multi-book review just published too. This one's written by the above-mentioned Jerry Coyne (who will be in Vancouver for a talk on fruit flies this weekend), and it covers both Dawkins's book and a newer one, What Darwin Got Wrong, by Jerry Fodor and Massimo Piattelli-Palmarini, which has been getting some press.

Darwin got a lot of things wrong, of course. There were a lot of things he didn't know, and couldn't know, about Earth and life on it—how old the planet actually is (4.6 billion years), that the continents move, that genes exist and are made of DNA, the very existence of radioactivity or of the huge varieties of fossils discovered since the mid-19th century.

It took decades to confirm, but Darwin was fundamentally right about evolution by natural selection. Yet that's where Fodor and Piattellii-Palmarini think he was wrong. Dawkins (and Coyne) disagree, siding with Darwin—as well as almost all the biologists working today or over at least the past 80 years (though apparently not Piattellii-Palmarini).

I'd encourage you to read the whole review at The Nation, but to sum up Coyne's (and others') analysis of What Darwin Got Wrong, Fodor (a philosopher) and Piattelli-Palmarini (a molecular biologist and cognitive scientist) seem to base their argument on, of all things, word games. They don't offer religious or contrary scientific arguments, nor do they dispute that evolution happens, just that natural selection, as an idea, is somehow a logical fallacy.

Here's how Coyne tries to digest it:

If you translate [Fodor and Piattelli-Palmarini's core argument] into layman's English, here's what it says: "Since it's impossible to figure out exactly which changes in organisms occur via direct selection and which are byproducts, natural selection can't operate." Clearly, [they] are confusing our ability to understand how a process operates with whether it operates. It's like saying that because we don't understand how gravity works, things don't fall.

I've read some excerpts of the the book, and it also appears to be laden with eumerdification: writing so dense and jargon-filled it seems to be that way to obscure rather than clarify. I suspect Fodor and Piattelli-Palmarini might have been so clever and convoluted in their writing that they even fooled themselves. That's a pity, because on the face of it, their book might have been a valuable exercise, but instead it looks like a waste of time.

Coyne, by the way, really likes Dawkins's book, probably more than I did. I certainly think it's a more worthwhile and far more comprehensible read.
