I wasn’t looking for this oldie at this time, and had forgotten it (I don’t have the heart to look at the number of posts I’ve made on FR, or the number of topics I’ve started on FR), but it pertains to Raup and the periodic mass extinction thing. :’)

He published a book about the Nemesis Affair during the height of the Big Rock controversy which I found of interest, it is buried along with a couple of thousand others in my library.

The grad student that did his periodicity research died very young, a shame. It confirmed my theory that gradualist's suck.
