|We have dominated the planet, uncovered the secrets of the atom and travelled to the moon. But how did humans come to be so successful? Discover how our bodies hold all the clues we need to unpick the epic story of our evolution.
Presented by Dr Alice Roberts, this series explores the powerful and surprising anatomical changes that have given us, and our ancestors, the edge to survive over a 6-million-year evolutionary journey.
Everything from the way that we walk, to the shape of our jaw and even the way our thumbs move, connects us intimately to the struggles and triumphs of our ancestors. Yet many of those evolutionary changes have come at a cost - from bad backs to difficult childbirth.
In each episode of this three-part series key features of our anatomy act as a trigger for a journey through time and across the globe on a quest to understand how and why we became what we are today.
This week Alice Roberts reveals the advantages our skeleton has brought us as we learned to walk on two feet - from hunting to tool use.
