Fascinating. How might this affect the Evolution vs. Creation debate?
Looks to me like a discussion of well known facts of science which even creationists would not deny.

Originally posted by David CCorrect me if I'm wrong, but wouldn't asexual reproduction inhibit the process of evolution? And hence sexual reproduction encourage it?

So I suppose the existence of the sexes is more evidence for evolution.

Originally posted by Conrau KYou're wrong. Asexual reproduction would promote genetic differentiation between populations of the same species. Sexual reproduction promotes homogenisation of genes between members of the same population (although not necessarily the same species, if two populations are geographically isolated).

Originally posted by sonhouseCertainly asexual species survive for shorter periods than sexual ones. It's believed that sex evolved as a counter measure to parasites,since the recominbation of genes prevents parasites from spreading rapidly through the population. Sex prevents genetic drift by allowing recombination, and it's only really through some type of isolation (whether geographical or otherwise) that two sexually reproducing populations can speciate.
