Sexual selection is selection due to differential access to quantity and quality of mates. One form of it, intersexual selection, is due to differential access to mates driven by the mate preferences of individuals of the other sex. The major question about sexual selection pursued in theoretical
I argue that the magnitude and nature of sex differences in aggression, their development, causation, and variability, can be better explained by sexual selection than by the alternative biosocial version of social role theory.
