Document Summary
Millions of years ago we were apes living in africa. More than 6 million years ago, we took that first step to separate from the apes. 3 million years ago, we see the routes of our big brain begin to take hold in a tiny creature more like a chimp than a human. The frontier of human evolution is really being brought to this sharp edge. We now know that many different like species lived together on the planet until one day, there was only us. Homo sapiens were the most adaptable creatures on earth. Millions of years ago on the planes of africa, an event happened. Apes walked on four legs stood up and walked on two. Eventually this change in posture is a change in their brains. In the sahara desert, a fossil called tumi maybe the secret on how we first walked up. The afar, north eastern africa, it is part of the great rift valley.
