Kanzi, 31-year-old Food Cooking Bonobo Chimpanzee

DNA evidence suggests the bonobo and common chimpanzee species effectively separated from each other fewer than one million years ago. The chimpanzee line split from the last common ancestor shared with humans approximately six to seven million years ago. Because no species other than Homo sapiens has survived from the human line of that branching, both Pan species are the closest living relatives of humans and cladistically are equally close to humans.
Physical description
It is commonly considered to be more gracile than the common chimpanzee, and females are somewhat smaller than males. Body mass in males ranges from 34 to 60 kg (75 to 130 lb), against an average of 30 kg (66 lb) in females. The total length of bonobos (from the nose to the rump) is 70 to 83 cm (28 to 33 in). Its head is also smaller than that of the common chimpanzee with less prominent brow ridges above the eyes. It has a black face with pink lips, small ears, wide nostrils, and long hair on its head that forms a part. Females have slightly more prominent breasts, in contrast to the flat breasts of other female apes, although not so prominent as those of humans. The bonobo also has a slim upper body, narrow shoulders, thin neck, and long legs when compared to the common chimpanzee.
