Primate social organizations can generally be categorized into two types: 1) solitary foragers or dispersed polygyny where females forage alone and males monopolize access to females, and 2) where females forage together in female-bonded groups that are larger and contain multiple males. Group structures range from one-male harems to multi-male/multi-female groups. The type of social structure adopted depends on factors like the nature of resources and how defendable or monopolizable they are.
