Fauna of South Africa
The largest primate in the region, excluding humans, is the chacma baboon. A true generalist, it is found in virtually all habitats in South Africa. The other primates in the region are the vervet monkey and the Samango monkey. They are mainly frugivores, although they are true opportunists and may take eggs and nestlings from bird nests.
Orangutan
The three orangutan species are the only extant members of the subfamily Ponginae. This subfamily also included the extinct genera "Lufengpithecus", which lived in southern China and Thailand 2–8 mya, and "Sivapithecus", which lived India and Pakistan from 12.5 mya until 8.5 mya. These apes likely lived in drier and cooler environments than orangutans do today. "Khoratpithecus piriyai", which lived in Thailand 5–7 mya, is believed to have been the closest known relative of the orangutans. The largest known primate, "Gigantopithecus", was also a member of Ponginae and lived in China, India and Vietnam from 5 mya to 100,000 years ago.
