The author this piece, David Gelernter, is a distinguished scholar, a bit of whose work I've read, and I'm inclined to trust him. But I found the piece very surprising.
Darwinian evolution is a brilliant and beautiful scientific theory. Once it was a daring guess. Today it is basic to the credo that defines the modern worldview. Accepting the theory as settled truth—no more subject to debate than the earth being round or the sky blue or force being mass times acceleration—certifies that you are devoutly orthodox in your scientific views; which in turn is an essential first step towards being taken seriously in any part of modern intellectual life. But what if Darwin was wrong?
A quick look 0n the Web turned up this piece, which argues that the Cambrian Explosion does not, in fact, "challenge the fundamental correctness of the central thesis of evolution."
