  3. Primates are mammals that have: • Opposable thumbs • Large brain • Good, stereoscopic vision • Ability to brachiate • Flexible elbows for hand rotation • Grasping feet

  5. Hominid Evolution • Hominids developed 5-8 million yrs ago • Hominids are bipedal • First hominids were in genus Australopithecus • “Lucy” most famous fossil hominid • More modern hominids were in genus Homo

  6. More recent humans • Homo sapiens • (developed 400,000 years ago) • Neanderthals • Europe arrival (100,000 years ago) • Cro-Magnon • Europe arrival (40,000 years ago) • Americas arrival (12,000 years ago)
