Formerly the bonobo was known as the "pygmy chimpanzee", despite the bonobo having a similar body size to the common chimpanzee. The name "pygmy" was given by the German zoologist Ernst Schwarz in 1929, who classified the species on the basis of a previously mislabeled bonobo cranium, noting its diminutive size compared to chimpanzee skulls.
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 ...
Her bonobo research examines why bonobos have evolved a very different social system compared to the closely related chimpanzee. She graduated from Cambridge University, UK, with a BA in 1980, an MA in 1984, and a PhD from Stony Brook University , Department of Ecology and Evolution, New York in 1986.

Primates may egage in sexual activity as part of social bonding; including homosexual behaviour. [121] Such behavior play an important role in bonobo society in particular. female bonobos engage in mutual genital-rubbing behavior, possibly to bond socially with each other, thus forming a female nucleus of bonobo society.
Bonobo (video) Female chimpanzee at Tobu Zoo in Saitama, Japan. Anatomical differences between the common chimpanzee and the bonobo are slight. Both are omnivorous adapted to a mainly frugivorous diet. [50] [51] Yet sexual and social behaviours are markedly different.
Bonobos (Pan paniscus) are social animals that live in hierarchical structures, though not as hierarchical as chimpanzees. [115] Researchers Bräuer, Call, and Tomasello tested bonobos, together with other great apes , twice and twice failed to find evidence of inequity aversion.
[14] [41] Like bonobos, male chimpanzees have a long filiform penis with a small baculum, but without a glans. [44] Chimpanzees are adapted for both arboreal and terrestrial locomotion. Arboreal locomotion consists of vertical climbing and brachiation. [45] [46] On the ground, chimpanzees move both quadrupedally and bipedally.
