A recent Kenyan fossil find is challenging theories of human evolution. Two fossils – an upper jaw bone of a Homo habilis and a skull of a Homo erectus — reveal that the two species lived side by side for half a million years instead of evolving one after the other as previously thought. Join Kojo as we discuss the discovery and its significance to human prehistory.
