Andrew Marr sets off on an epic journey through 70,000 years of human history. Starting with our earliest beginnings in Africa, Andrew Marr traces the story of our nomadic ancestors as they spread out around the world and settled down to become the first farmers and townspeople. He uncovers extraordinary hand-prints left in European caves nearly 30,000 years ago and shows how human ingenuity led to inventions which are still with us today.
