Male Chimpanzee

Chimpanzees are our closest living relatives, sharing more than 98 percent of our genetic blueprint. Humans and chimps are also thought to share a common ancestor who lived some four to eight million years ago.

Chimpanzees live in social communities of several dozen animals, and can habituate themselves to African rain forests, woodlands, and grasslands.

Although they normally walk on all fours (knuckle-walking), chimpanzees can stand and walk upright. By swinging from branch to branch they can also move quite efficiently in the trees, where they do most of their eating. Chimpanzees usually sleep in the trees as well, employing nests of leaves.

Chimps are generally fruit and plant eaters, but they also consume insects, eggs, and meat, including carrion.
