Brian Cox and Robin Ince are joined by comedian Ross Noble, Professor Danielle Schreve and Professor Chris Stringer as they look at the tricky job of piecing together the history of modern humans and how we came to be here. They look back to the earliest known human ancestors and the fossils and tools that have allowed us to paint the picture of our journey out of Africa, to become the last surviving human species on the planet. They ask why we have gone from more than 5 or 6 species of humans some 200,000 years ago, to just 1 today. They also look at how discoveries made in just the last 5 years have completely transformed our understanding of human history and what new DNA technology has revealed about our ancient past. They also reveal what surprising tropical animal remains have been found buried deep under Trafalgar Square.
