Comparison of the physical characteristics of grooming in two species of macaques (Macaca nemestrina and M

Author examined social grooming in groups of bonnet and pigtail macaques to test hypothesis that the physical aspects of grooming (body sites, postures, methods) evolved in more aggressive species of primates to serve social functions (proximity maintenance and tension reduction)....

Interaction between adult male and immature captive chimpanzees: Implications for housing chimpanzees

These observations suggest that captive adult male chimpanzees have the potential to develop affiliative relationships with immature conspecifics. Housing adult males in groups along with infants may be an important way of increasing the social complexity of the males' environments.
