The smash hit Netflix documentary “Unknown: Cave of Bones” has kicked off an all-out science brawl. The film makes extraordinary claims about a strange ape-like creature that lived hundreds of thousands of years ago — claims that rewrite what it means to be human. But some scientists are pushing back, saying that at this point, these extraordinary claims aren’t backed up by extraordinary evidence. So, what’s going on? Is “Cave of Bones” a Cave of Lies? We chat to the man at the center of the controversy, National Geographic Explorer In Residence Lee Berger, as well as a couple of the scientists pushing back against his work: Professor Andy Herries and Associate Professor Jamie Hodgkins.
