Everything you didn’t know you didn’t know about Neanderthals. As wolves are to dogs, these people are our evolutionary cousins. Were Neanderthals just a bunch of ‘neanderthals’ (cue common insult), or was there so much more to them? It seems there was. We are learning more and more everyday and my guests are at the absolute cutting, digging, scraping and genetically testing edge. Professor Tom Higham, author of ‘The World Before Us’ and Dr Rebecca Wragg Sykes, author of ‘Kindred’ tell me who they were. Mysteries are solved but one big one remains. Why did they go extinct?
