We have uncovered the secrets of the atom, travelled to the moon, and dominated planet Earth. But how did humans come to be so successful? This three-part series reveals the powerful anatomical changes that have given us - and our ancestors - the edge over all other life on Earth. From the way we walk, to the shape of our jaw and even the way our thumbs move, we are connected intimately to the struggles and triumphs of our ancestors. However, many of these changes have come at a surprising cost, and the problems we face now are a direct consequence of our evolutionary journey. As much about our bodies today as about our bodies 6 million years ago, Origins of Us will change the way you see yourself.
