THE ORDER OF PRIMATES The forest as the human birthplace

Primate evolution and taxonomy

The impact of the forest on human evolution Eyes that look forward: stereoscopic vision From mammalian paws to hands and feet From large litters to fewer offspring. Closer mother / child bond – greater maternal care Increase in vocalization Restructuring of the brain

Africa as the human birthplace Monkeys are found in Africa, Asia, and the Americas Apes evolved in Africa and Asia, but not in the Americas.  Africa: Chimpanzees, Gorillas  Asia: Gibbon, Orangutan Hominids evolved only in Africa.

Summary The forest prepared the basic physical and behavioral platform from which humans were to emerge. Primate evolution occurred in forests around the tropical world. The cutting edge of human evolution occurred in Africa. The closest biological and behavioral relatives of humans are the chimpanzees.
