^^^^^^ CB: My historical-materialist explanation for sociobiology is that anthropology had become too ,well, historical materialist and left for the bourgeois ruling class' agents and guardians of academe. Anthropology has found lots of primitive communism in the most fundamental human societies. Human nature is more communist than bourgeois. There is no need for a separate discipline of "sociobiology". Anthropology, archaeology and physical anthropology had already established large amounts of research, empirical investigation and theory on human evolution when "sociobiology" popped up. But anthropology was confirming anti-bourgeois, anti-individualist, anti-private property, communistic versions of human nature too much. So, the bourgeoisie got some academics to start "sociobiology", which uses bourgeois concepts of human nature, and largely projects bourgeois social structures, such as rugged individuals, selfishness, inclination to war, and the like into the distant human past.
By the way, andie's hypothesis seems similar to Desmond Morris' hypothesis.
The evolutionary purpose of orgasms
Evolutionary biologists put forward several hypotheses for explaining the role of the female orgasm in terms of the reproductive process. In 1967, Desmond Morris first suggested in his pop-science book The Naked Ape that female orgasm evolved to encourage physical intimacy with a male partner and help reinforce the pair bond. Morris suggested that the relative difficulty in achieving female orgasm, in comparison to the male's, might be favourable in terms of Darwinian evolution by leading the female to select mates who bore the qualities of patience, care, imagination, intelligence and so forth, this in contradistinction to qualities such as size and aggression, which pertain to mate selection in other primates. Such advantageous qualities thereby become accentuated within the species, driven by the very differences between male and female orgasm. After all, were the male to be motivated by and taken to the point of orgasm in the same way as the female, those advantageous qualities would not be needed: self-interest would do the trick.
He additionally proposed that orgasm might facilitate conception by exhausting the female and keeping her horizontal, thus preventing the sperm from leaking out. This possibility, sometimes dubbed the "Poleax hypothesis" or the "Knockout hypothesis", is now considered as highly doubtful http://en.wikipedia.org/wiki/Orgasm
