Why Did Ancient Humans Actually Evolve In Africa

Why Did Ancient Humans Evolve In Africa? We're taught Africa was a paradise that gave our ancestors the time to grow big brains. The fossil record says the opposite: Africa was one of the most unstable landscapes on Earth, and that instability very nearly wiped us out more than once. This video walks through the real science — vanishing lakes, a population crash to under 1,300 people, and why there was never a single "Garden of Eden" — to explain why the harshest continent on Earth built the most adaptable species on it.
