Document Summary
Five behavioral patterns qualified as social traditions: handsniffling, sucking of body parts, and three types of games. Some conventions independently invented in virtually identical form at multiple sites. Extinction of several conventions observed during course of study, rarely last longer than 10 years. Hypothesized that the monkeys are using these group or clique specific social conventions to test the quality of social relationships. To understand socioecological factors, it is necessary to look beyond. Independently evolved many traits that are present in humans and. Large brain-body ratio, omnivorous, extractive foraging, sometimes share food, skilled tool users, nonconceptive sex, alloparenting, lethal agg, complex social relationships.

Behavioral tradition: a practice that is relatively long-lasting and shared among members of a group, each new practitioner relying to some extent upon social influence to learn to perform it.
