  1. 16.1 Primate Evolution Try this: Write your name without using your thumbs!

  2. Primate Evolution • 1871 Darwin said there might be a link between monkeys, apes and humans • Today scientists study living primates and fossils to learn about primate evolution

  3. Primate Evolution • A primate is a group of mammals that includes lemurs, monkeys, apes and humans Vervet

  4. Primate Evolution • Primate features • Opposable thumbs – allows primates to grasp • Large brain volume, round head and flat face • Strong vision, binocular vision • Flexible arm movement – for moving in trees • Flexible joints – allow for wide range of motion • Feet that can grasp objects

  5. Primate Evolution • Primate features • Opposable thumbs • Large brain volume • Strong vision, binocular vision • Flexible arm movement • Flexible joints • Feet that can grasp objects

  6. Primate Evolution • Similarities tell us primates share evolutionary history • Evidence = anatomy, genetics

  7. Primate Evolution • Prosimians • lemurs, aye-ayes, tarsiers • Small bodies, large eyes, nocturnal • Live in tropical forests and eat insects, seeds, fruit • First fossils 50-55 million years old

  8. Primate Evolution • Anthropoids • Monkeys, hominoids (apes and humans) • Larger bodies, more complex brains than prosimians

  9. Primate Evolution • Anthropoids • Monkeys • New World Monkeys • Old World Monkeys

  10. Primate Evolution • Anthropoids • Monkeys • New World Monkeys • South and Central America • Arboreal – live in trees • Prehensile tail – can grip • Marmosets and spider monkeys

  11. Primate Evolution • Anthropoids • Monkeys • Old World Monkeys • Africa to Japan • Some live in trees, some on land • Tail not prehensile, larger than NWM • Colobus monkeys and baboons

  12. Primate Evolution • Anthropoids • Monkeys • New World Monkeys • Old World Monkeys • Hominoids • Apes • Humans

  13. Primate Evolution • Anthropoids • Monkeys • New World Monkeys • Old World Monkeys • Hominoids • Apes • No tails, muscular arms for tree climbing • Social groups, long term parental care • Gibbons, orangutans, chimpanzees, gorillas • Humans

  14. Primate Evolution • Anthropoids • Monkeys • New World Monkeys • Old World Monkeys • Hominoids • Apes • Humans • Walk upright • Larger brain

  15. Primate Evolution • Anthropoids • Evolved worldwide • New World monkeys – 30 – 35 million years ago • Old World Monkeys – 20 – 22 million years ago • Hominoids - gibbons, then orangutans, then chimps and gorillas, then humans
