Enigma Man: A Stone Age Mystery

A team of Australian and Chinese scientists discover mysterious ancient human remains from a remote cave in South West China. The bones are unlike any living human or any ancient human known to science, yet they were alive at the same time as humans of our own kind. Could they represent a new human species? And if so, what happened to these people? Join the investigation to unravel the mystery and travel back in time into their Stone Age world. These ancient bones challenge everything we think we know about human evolution and raise possibly the biggest question of all – what truly makes us human? (ABC/Nine Network)
