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.
Mammal
The earliest known ancestor of primates is "Archicebus achilles" from around 55 million years ago. This tiny primate weighed 20–30 grams (0.7–1.1 ounce) and could fit within a human palm.
