Pan troglodydes, common chimpanzee



Back to all primate species



Taxonomic lineage

Genus Pan (chimpanzee) belongs family Hominidae (great apes) together with Gorilla, Homo (human), and Pongo (orangutan). The orangutan is the most primitive of great apes and is separated in the subfamily Ponginae. Thus, great hominoid trio consists of Homo, Pan and Gorilla. Chimpanzee is considered to be the closest human relative.

The vernacular name chimpanzee is a Bantu word used originally in northern Angola and Congo to refer to these animals.

Life history

Average ovarian period length is 37.3 +/- 3.6 days (Young and Yerkes, 1943).

Interbirth interval is about 68 months (wild chimpanzees require a mean of 42 months to regain fertility after previous birth). Potential fertility is about 5. Number raised to sexual maturity is about 2-3 individuals. Thus, fertility data suggest that speed of chimpanzees' reproduction is barely sufficient to maintain their population level.
