While primate social systems take many different forms, there some consistent patterns. Here will focus on information regarding the fantastic and interesting diversity of social systems in the living nonhuman primates. Investigate the social organization of a number of primate species. Then answer the questions.

1			Does there appear to be a main pattern in grouping or social organizations in all of these primates? What are some commonalities? What are some major differences?
2			Do patterns of dominance differ across species?
3			Do there appear to be any relationships between phylogeny (which group a species belongs to, such as neotropical monkeys, Old world monkeys, apes,) and social organization?
