The Great Human Odyssey explores the unlikely survival and the miraculous emergence of Homo sapiens as the world's only global species. 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 on foot, survive frigid ice ages, and sail to remote Pacific islands? Great Human Odyssey is a spectacular global journey following their footsteps out of Africa along a trail of fresh scientific clues.
