ABSTRACT
The mythologically typical primate has social relationships based on female philopatry and male dispersal, which makes relationships among female kin the major organizing prin ciple of social life, causes a high level of sexual dimorphism that leads to high levels of compe tition between males over females, and results in male dominance of and sexual aggression toward females. Because of this male competi tion and aggression, it has been assumed that sexual behavior is primarily for reproduction.
