 Gould points out, for instance, that mass
extinction events have had profound impacts on the biota, and that Darwin
never argued that organismal selection ALONE explained the diversity of
life, having, among other things, mentioned "use and disuse," the
cornerstone of the mechanism for evolution advanced by Lamarck, as impacting
evolution.

CB: I'm thinking mass extinction events are prime examples of Darwin's idea.
Extinction is critical in the Darwin analysis.
So, the mass extinction of the dinosaur specieses, with mammals' species
ending up more fit relative to the radically changed environment, is a prime
empirical example of Darwin's idea at work, no ?
