This is a global detective story, featuring new fossil finds and the latest genetic research. It's a story that revolves around a shocking revelation. In prehistoric times, we met and mated with other types of human – like Neanderthals, Denisovans and Homo erectus. This mixing of genes helped us survive - and ultimately thrive.
Scientists are beginning to realize that ours is not a pedigree species, but a patchwork. We are all hybrids.
