Where do human come from?

-       For millions of years, monkeys live in forests and jungles (long arms and tails)

-       Hot, humid, tropical weather (tall trees: shelters and food)

-       Continents constantly move (about 2cm per year), after a few million years, some places became colder, less rain

-       Tall trees became woodland or shrubs

-       Monkeys must learn to live on the ground to look for food and stay away from enemies

-       Evolute to longer legs to stand up and look ahead; shorter arms (no need to swing between trees), shorter tails

-     

 

 - Lucy, 3.2 million years old, Ethiopia

- Java man, 1 million years, Indonesia

- Peking Man, 0.4 million years, Northern China

- About 50000 years ago, wise men crossed Bering Strait and arrived in North America (Alaska, Yukon, NWT). We found evidence of fire and primitive spearheads from obsidian (flint) and dated these items

- they were stuck in those locations for about 5000 years. Big ice sheets covered the rest of North America (south of Yukon, NWT)

- we found spear points (sharpened rocks and bones), signs of fire (cooking, keep warm)

- carbon 14 dating – can determine the date when the wood was burned or when the animal bone was formed (accurate within 200 to 300 years)

- they still chased after animals for food (bison, buffalo, mammoth, caribou). Hunt as a group/tribe

 

- when the ice sheets started melting, they moved south to the rest of Canada, US, Mexico and even South America

- these are the Native People who arrive in North America first, before the Europeans
