About the Show

We humans consider ourselves unique. In terms of evolution, our ancestors and cousins have all died out. But ground-breaking discoveries made in the last few years have transformed our beliefs about our past. We now know there were at least four distinct species of human alive on the planet at the same time – and possibly more. Who were these ‘lost tribes’ of humanity? What happened when we met them? And where did they all go? The answers strike deep at the core of who we think we are.
