What Happened When Ancient Humans Met Another Species of Human?

Forty-five thousand years ago, a lone hunter followed strange footprints through the snow and came face to face with a different kind of human. What happened next? For decades, scientists assumed it ended in war. Then ancient DNA revealed something nobody expected: the story didn't end with the Neanderthals. It continues inside us. In this video, we follow the evidence from the first meeting between modern humans and Neanderthals, through the 2010 DNA discovery, a jawbone from Romania, and a mysterious third human species known from only a few fragments, the Denisovans.

The video says so where that applies.
