The gorilla, the largest of the living primates, is a ground-dwelling omnivore that inhabits the forests of Africa. Gorillas are divided into two species and (under debate as of 2006) either four or five subspecies. Its DNA is 97%-98% identical to that of a human,In a talk presented at the Annual Meeting of the American Anthropological Association on November 20, 1999, Jonathan Marks stated: "Humans, chimpanzees, and gorillas are within two percentage points of one another genetically." and is the next closest living relative to humans after the two chimpanzee species.
