1 Primate Evolution KEY CONCEPT Humans appeared late in Earths history.

2 Primate Evolution Humans share a common ancestor with other primates. Primates are mammals with flexible hands and feet, forward-looking eyes and enlarged brains.

3 Primate Evolution Primates evolved into prosimians and anthropoids. –Prosimians are the oldest living primates. –They are mostly small and nocturnal.

4 Primate Evolution –They are subdivided into the New World monkeys, Old World monkeys, and hominoids. – Anthropoids are humanlike primates. –Homonoids are divided into hominids, great apes, and lesser apes. –Hominids include living and extinct humans.

5 Primate Evolution Bipedal means walking on two legs. –foraging –carrying infants and food –using tools Walking upright has important adaptive advantages.

6 Primate Evolution There are many fossils of extinct hominids. Most hominids are either the genus Australopithecus or Homo. Australopithecines were a successful genus. The Homo genus first evolved 2.4 million years ago.

7 Primate Evolution

8 Modern humans arose about 200,000 years ago. Homo sapiens fossils date to 200,000 years ago. Human evolution is influenced by a tool-based culture. There is a trend toward increased brain size in hominids. Australopithecus afarensis Homo habilisHomo neanderthalensis Homo sapiens
