	Mike, you seemed to have missed the point. I did not write that sex makes
no sense (even after 25 years of marriage it does :-) ), I wrote that Dr.
Eldredge (1995 book) wrote that sex is a paradox from the ultra-Darwinist
(as in Dr. Dawkins)  point of view.

	Read his book, it will serve you well in your studies. (Eldredge is a
major player, if you did not know)

	Regards, Joe
