This chapter examines attempts to integrate several of the preceding hypotheses into a more
general theory of social structure. It presents a few hypotheses relating to other aspects of …

For many animal taxa, the extent to which phylogeny can account for the form of species'
social systems has seldom been investigated formally. A quantitative phylogenetic analysis …

Publisher Summary The origins of primate sociability and the sources of order in the
societies of monkeys and apes are highly complex. The living primates have evolved as …

Primates are a large and diverse order of mammals. They play an important role in studies of
the evolution of sociality because there is considerable diversity in social organization and …

P RIMATE SOCIALITY has many faces. Some callitrichines form small groups with just one
reproducing female and others who help care for her young. Hamadryas baboons (Papio …

We review evolutionary processes and mechanisms that gave rise to the diversity of primate
social systems. We define social organization, social structure and mating system as distinct …

Social groups are maintained by communication between individuals, which is brought
about by a series of largely innately determined gestures and responses. The way in which …

Attempts to explain differences in the size and structure of primate groups have argued that
they are a consequence of variation in the intensity of feeding competition caused by …

Primates, as long-lived, iteroparous, socially complex mammals, offer the opportunity to
assess the effects of behavior and demography on genetic structure. Because it is difficult to …

The study of social relationships lies at the core of socioecology, which attempts to explain
social behaviour as an adaptation to ecological factors. Studies of primates have featured …
