Why do men show a more aggressive behavior than women? For a evolutionary anthropology of the aggressive behavior

Abstract

Violence is something that several societies carry among its cultures as a common characteristic, some in larger ways, and some in smaller measures. However, in all of them, men show a more aggressive behavior than women. In that way, there are evidences, that this reality has a correlation with the evolutionary past from our specie. So, this studies, acts with two explanatory hypotheses for this case. One concern to the labor sexual division; the other to the sexual selection in the parental charge and the selectivity of the females. Both seem to have exercised pressures in a way of composing psychological aggressive tendencies.
