Yeah. I guess, thinking about it, it's not such a radical hypothesis to have. The difficult part is offering arguments for how that may be the case, and exploring the ramifications. In many animals biological differences are exaggerated by various behaviors, for example a male bird adding a fake feather to his tail to exaggerate the tail-size that is already, on average, bigger than a female's. So I think to some important degree our socializing men and women toward greater extremes is an attempt to accentuate those already-present biological differences, and, ultimately, to attract mates.
