> Males mammals tend to get aggressive when another male encroaches on their "space" or dominion - homicidal even. While that's probably true about many mammals, that doesn't mean that it's true for humans, at least not at the biological level. It's certainly within the realm of possibility that our men's aggressiveness towards other men that approach upon "their women" is a societal construct, not a biological one. This is supported by the fact that there are human (and close ape) societies in which that is the case. Sex at dawn pokes quite a lot of holes in the standard narrative of human sexuality; and they propose an alternative one which seems to fit some of the facts better. While their model might not be accurate or, and may even be wrong, I've yet to seen anyone poke serious holes in it or manage to patch the holes they've poked in the standard narrative. I'd appreciate being pointed to such arguments.
