  1. The forest as the human birthplace THE ORDER OF PRIMATES

  2. Primate evolution and taxonomy

  3. 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

  4. 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.

  5. Gibbon

  6. Orangutan

  7. Gorilla

  8. A look at our closest relatives: chimpanzees

  9. Geographical distribution of chimps

  10. Increase in mother – child bond

  11. Chimpanzee social bonds

  12. Chimpanzee tool use

  13. 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.
