There is, actually, quite a bit more to human survival than this if one insists on including culture, which is, at its core, simply another ploy in the natural selection game. Here the value of the male is what he brings to the game in his normal areas of specialization of defense, construction, and beer-drinking. It is not to say that females cannot fill that function; it is to say that incorporating specialists tends to stretch the corpus of cultural survival ploys. Moreover, can we say that a culture in which nobody lights farts with a Zippo or a .45 is a culture worth living in? I thought not.
