Bbc Earth Walking With Cavemen: Series 1 (2004)

Follow your family tree all the way back to the first primate ancestors to stand on two legs. See how the first sparks of reason in early humans helped them to adapt in an ever-changing world.

Breaking the mould of previous "Walking with" offerings, the BBC's Walking with Cavemen sees Professor Robert Winston follow in the footsteps of ancient man in a series that traces the history of humanity from bipedal ape-men (Australopithecus Aphaeresis) to the awakening of the human mind's potential with Homo Erectus. Spread over four fascinating half-hour instalments, Wilson presents an accessible and populist, but still suitably anthropological study on how apes became human and the traits that we inherited from our earliest ancestors.

A fragment of a pinky bone and a tooth twice the size of today’s average molar are the only remnants of a species we now know lived at the same time and place as modern humans—and interbred with them. They are a part of us we never knew existed. What did these "people" look like? And how do they fit into what we thought we knew about our biological development as a species?
