Chimpanzees, sometimes colloquially chimps, are two extant hominid species of apes in the genus Pan. The Congo River divides the native habitats of the two species:
- Common chimpanzee, Pan troglodytes (West and Central Africa)
*Bonobo, Pan paniscus (forests of the Democratic Republic of the Congo)
Chimpanzees are members of the family Hominidae, along with humans, gorillas, and orangutans. Chimpanzees split from the human branch of the family about four to six million years ago. Chimpanzees are the closest living relatives to humans, being members of the tribe Hominini (along with extinct species of subtribe Hominina). Chimpanzees are the only known members of the subtribe Panina. The two Pan species split only about one million years ago.
