The bonobo (/bÉ.ËnoÊ.boÊ/ or /ËbÉ.nÉ.boÊ/; Pan paniscus), formerly called the pygmy chimpanzee and less often, the dwarf or gracile chimpanzee, is an endangered great ape and one of the two species making up the genus Pan; the other is Pan troglodytes, or the common chimpanzee.
When adult bonobos and chimpanzees stand up on their legs, they can both attain a height of 115 cm (45 in). The bonobo's head is relatively smaller than that of the common chimpanzee with less prominent brow ridges above the eyes.NA evidence suggests the bonobo and common chimpanzee species effectively separated from each other fewer than one million years ago. The Pan line split from the last common ancestor shared with humans approximately six to seven million years ago.
