To Doug:
Come on. These guys are physicists. They don't need natural historians
with messy data that are always consistent with a slew of different
interpretations putting constraints on THEIR theories. No attempt to test
the reasonableness of this model with detailed data from any fossil record.
To Una:
I agree with everything you've said, especially the point about multiple
causes. That's what I think we're looking at in the K/T fossil record and
that's why it's defied all previous attempts to find a single pattern.
To John:
I agree with your characterization (caricaturization? :) ) of the
philosophical differences separating us. But I disagree with your
interpretation(s). To respond in detail would be to go back over the same
ground. Let's call it a day and move on to other things.
If anyone out there wants a reprint of the MacLeod and Keller paper that
John Alroy and I have been discussing I still have some left. It's best
for the arguments made therein to be read in their entirety.
