The bonobo (/ b ə ˈ n oʊ b oʊ, ˈ b ɒ n ə b oʊ /; Pan paniscus), also historically called the pygmy chimpanzee (less often the dwarf chimpanzee or gracile chimpanzee), is an endangered great ape and one of the two species making up the genus Pan (the other being the common chimpanzee, Pan troglodytes). [4]
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 ...

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.
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.
One study analyzed sounds made by human babies and bonobos when tickled. It found that although the bonobo's laugh was a higher frequency, the laugh followed the same sonographic pattern as human babies and included similar facial expressions. Humans and chimpanzees share similar ticklish areas of the body such as the armpits and belly. [6]
The chimpanzees in the area have little fear of humans, because of a local legend, that humans and bonobos were cousins. "According to this belief, an older brother in a family of bonobos held to their traditional lifestyle and his descendants thus remained in the forest as bonobos. However, his younger brother was tired of eating raw foods.
