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.
Deme (biology)
Primates, for example, have the second highest speciation rate among mammals, with one speciation event per lineage every 3 million years. However, not all primate species have a high speciation rate and this is seen back in there deme size and social structure. Geunons ("Cercopithecus"), for example, live together in small polygynous troops and are a quite diverse genus. On the other hand, baboons ("Papio") have a much lower speciation rate. Baboons have larger deme sizes because they live in polygynous multi-male troops. These baboon demes are usually allopatric but gene-flow still exists between demes with hybridization being common.
