Arboreal locomotion consists of vertical climbing and brachiation. [45] [46] On the ground, chimpanzees move both quadrupedally and bipedally.

For instance, chimpanzees (Pan troglodytes) have patrilineal social systems, where the males usually remain in their natal groups and the females emigrate into neighboring groups. Conversely, in the matrilineal societies of bonobos (Pan paniscus), it is the females who remain in their natal groups and the males who disperse to new groups ...
