In March 2012 two paleoanthropologists announced the startling discovery of prehistoric human remains from a remote cave in South West China. They dubbed them the ‘Red Deer Cave people’. They were unlike any human remains known to science. Not only were they a unique mix of primitive and modern features, but they were also young – between 11,5000 and 14,500 years old. That makes these fossils the youngest ever found which possess physical features different to our own – much younger than our famous ancient cousins, the Neanderthals and even the primitive Pygmy Hobbits from Indonesia. ENIGMA MAN – A STONE AGE MYSTERY follows the scientific team on their mission to solve the mysteries of these bones, and unravel the clues that reveal incredible details about how these people lived, and possibly why they died. Tantalising evidence from the cave site in China poses some chilling, even macabre, possibilities concerning their fate and their connection to us. The implications of the discovery for understanding the evolution of our own species, and the broader human story, are profound. Scientific orthodoxy contends that our modern human ancestors only inhabited East Asia after the disappearance of earlier ancient humans. The existence of the Red Deer Cave people is further evidence that the truth may be something else entirely. Our own species may have coexisted with the Red Deer Cave people until very recently, for tens of thousands of years. Drawing together this latest discovery with other recent groundbreaking finds in the region, this documentary explores an amazing new chapter in our evolutionary story - the Asian chapter. Combining scientific adventure, insightful interviews, and stunning reconstructions ENIGMA MAN – A STONE AGE MYSTERY is a comprehensive account of an emerging new view of human evolution.
