The size and composition of primate groups exhibit significant variation across species and over time, with the number of adult males being particularly dynamic. Some groups feature single males monopolizing access to females, while others involve reproduction shared among multiple males. This variability is central to understanding adaptive differences in social systems. The presence of single or multiple males profoundly influences the reproductive strategies of both sexes, as well as shaping the animals' morphology and behavior.
