Figure 1 Multilevel societies. Top: geladas in Ethiopia (Photo: J. Kerby). Bottom: multilevel social organization of (A) geladas (Theropithecus gelada), (B) Hamadryas baboons (Papio hamadryas) and (C) snub-nosed monkeys (Rhinopithecus spp.). The gelada band consists of one team (dashed line), three single one-male units, one multi-male unit (m) and one all-male unit (a). The Hamadryas band consists of two clans (dashed lines) and a single one-male unit; several one-male units have a follower male (f) Other males do not form stable all-male units. The snub-nosed monkey band consists of six one-male units and one all-male unit (a). Outer layers of multilevel societies may constitute mere short-lived aggregations and are not shown here.
