Document Summary
Evo psychologist may point to consistencies across cultures and say although the : although the extent of the difference varies, men and boys are more physically aggressive in every culture so far studied. Animals - then it"s more parsimonious to attribute this diff to genes and bio of evolution than culture. The relationship is that in species in which there"s intrasex competition (again typically males competing to gain access to females) there is sexual dimorphism. So when you have males competing for access to females, you have reliable differences in the shape of males and females ex. Intra-sexual competition = larger size and greater aggression. (and not, chimp culture socializes them that way. ) If natural selection can shape all these other species such that the larger sex is more aggressi(cid:448)e, (cid:449)h(cid:455) (cid:272)ould(cid:374)"t the sa(cid:373)e pro(cid:272)ess appl(cid:455) to hu(cid:373)a(cid:374)s: evolutionary processes can explain why men are larger than women.
