Not sure why you would think I didn't read your piece, I stated up front that I wasn't saying you were wrong but that I thought parts of your arguments needed much more support. Your argument that the last 5-10,000 years of culture, most of which you characterize as patriarchal, could not be relevant to an evolutionary psychology perspective would only be true if several thousand years of a patriarchal environment were too short a period to cause evolutionary changes...the punctuated equilibrium findings about quite rapid evolutionary changes interspersed with long periods of evolutionary stasis suggest that a period thousands of years might be plenty time to create evolutionary changes.
I'm not a fan of evolutionary psychology perspectives for humans in general, given that our most profound adaptive trick is to create cultures to deal with changing or different environments rather that creating actual physical changes. That said, there are reasons why women can't play NFL football, that women tend to be far more successful in today's education systems, that men commit the vast majority of violent crimes, that men can impose a system of violent physical control over women, and I suspect that the sexual dimorphism, both physical and hormonal, that exists is in large part responsible. Were women equally strong and aggressive then the direction of partner violence would be far more balanced, and while we would condemn that violence we would not see it as a mainly one way street.
I also think that the powerful psychological mechanisms in both sexes to create pair bonding are beyond cultural, though culturally reinforced, and serve as evidence for the physical evolution of these systems. The supposed penial evidence for "sperm competition" seems sketchy at best, similar to serious hypothesizing I have seen from academic types (evolutionary science researchers) that the human shoulder was designed to throw punches that has recently circulated.
Had the researcher spent more time in the outdoors and playing fields, throwing tens of thousands of rocks, sticks, and balls, and not so many punches, he might have gone down a more realistic path of research.
We can't know what cultural response prehistoric societies had to what most cultures now see as cheating, the fact that this concept is so prevalent cross culturally, as is pair bonding, seems to argue against the idea of normative sperm competition, but then of course we don't know what practices were the norm in unrecorded societies.
