Essential Question How did brain size, jaw size, language and manufacture of tools change as hominids evolved into modern humans? What are the different parts of the brain?

5.7 Human Evolution

Questions to Answer Today! What is a human? What is a hominid? What were early humans (hominids) like? How have we changed? What will we be?

Why are we talking about this??? We want to know about our ancient hominid ancestors! Comparing skulls and bone structure of hominid fossils supports COMMON ANCESTRY!

Notebook Input Write down words in RED

Evolution of the Skull

A. Evolution of the Skull As human skulls evolved, there were: Smaller jaw sizes Larger skull size larger brain size

What do you observe changing over time? Bipedalism: Ability to walk upright

B. Bipedalism Other primates are quadrapedal=walk on 4 legs Hominids became bipedal=walk on 2 legs Bipedalism allows you to use your arms to carry things while you walk

Human Evolution Do you think our skulls were the only things to evolve over time?

C. The Evolution of Behavior As time progressed, we also started to see an evolution in behavior. With evolution came: Language Manufacture of tools Making tools = no longer using teeth as basic tools = smaller jaw size

What is a hominid? Any human-like species, including us. Bipedal (walks on two legs). Intelligent (large brain, uses tools). ----- Meeting Notes (10/25/12 08:55) -----

There have been at least a dozen different species of hominids over the last five million years or so.

Homo sapiens. Anatomically modern humans. Oldest fossils found so far are perhaps 195,000 years old. Found in Africa (also in Ethiopia).

D. Parts of the Brain

Notebook Output OR Choose to write one of the following: In your own words, explain how the hominid behavior of using tools affected skull anatomy OR In your own words, explain how change in skull/brain size affected hominid behavior
