The landmark series follows Dr Alice Roberts as she travels to the ends of the earth to trace the extraordinary beginnings of the human story for BBC Two.

Using the latest genetic, climate and archaeological evidence, she will discover the five epic routes our ancestors took across the globe, and the obstacles and brutal challenges they encountered along the way. She will discover where we came from, how our ancestors colonised the world, and how their journeys changed us. In this series Alice Roberts will show how most of us descend from a tiny group of men and women who left Africa in a perilous crossing - and then went on to colonise the rest of the world.

Stephen Oppenheimer's book OUT OF EDEN: THE PEOPLING OF THE WORLD will form the basis of episodes 1, 2 and 4.
