	I took the words of Mr. Moran to be on the original topic that started all
of this --- that Dr. Eldgrede has pointed out in his 1995 book that sex is
a paradox from the "ultra-Darwinist" point of view. Your words seems to
support that.

	What is your position on Eldredge's claim that sex represents a problem
for those like Dawkins who see game as simply the contest to leave as many
copies of one's own genes?

	Regards , Joe Potter
