Crash Course Big History: Full Series - Human Evolution: Crash Course Big History #6

In which John Green and Hank Green teach you about how human primates moved out of Africa and turned Earth into a real-life Planet of the Apes. And the apes are people! John and Hank teach you about how humans evolved, and the sort of tricks they picked up along the way like complex tool use, big brains, and fighting.

Our ancestors tamed fire, made pressure flake tools, and eventually smartphones. Learn more: http://www.bighistoryproject.com Crash Course is on Patreon!
