									Primate Evolution

Today’s Objectives: SOL BIO.8a-d


TSW investigate and understand how primates have changed through time, including:
– Examining fossil records – Recognizing how adaptations lead to natural selection

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

Early Primates
Appeared 60-65 million years ago  Prosimian


– Small bodies – Lemurs, Tarsiers


Anthropoids
– Human-like primates – Evolved in Africa

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

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)
