is this true? but if it is true how would i even make sense? why would smarter men evolve to be more prone to do something that is likely to lead them to not reproducing? i mean i would assume the "bull" would do most of the sex and thus be the one to be most likely im impregnating the wife? why would nature do this? would it not be better to have more high IQ individuals?
