The thing about "pet theories", however, is they have a way of cancelling each other out, and whithering away, especially over a time-span of decades. Someone once said that old scientists never change their mind, they just die off. Something like that. But anyway, the process of science is as important to understand as the subjects of science themselves, and Gould is excellent at putting the process in the spotlight, and the practitioners in the hot-seat.
Bump!!
But he died. So it's time to evolve a new punctuation. Instead of "!" for Gould it should be "!?".
