This course explores the behavior of wild primates and the ecological models that attempt to explain the evolution of these behaviors. The evolution and taxonomy of primates will be reviewed, followed by a brief history of wild primate studies. We will then explore primate behavior through theoretical frameworks ranging from socioecological theory to sexual selection. Topics discussed include, but are not limited to, socioecology, aggression, kinship, cooperation, reproductive strategies, cognition, and conservation. Those enrolled in 507 will have additional responsibilities assigned.
