Great Human Odyssey
Season 43
Episode 12
Our ancient human ancestors once lived only in Africa in tiny bands of a few thousand hunter-gatherers. Then we moved out of our African cradle, spreading rapidly to every corner of the planet. How did we acquire the skills, technology and talent to thrive in every environment on earth? How did our prehistoric forebears cross the Sahara, survive frigid ice ages, and sail to remote Pacific islands?
