Human Heaters: How It All Worked in 9 Minutes

What Did Ancient Humans Do When It Was Freezing Cold? You stood at a bus stop at minus fifteen this morning. Fifty thousand years ago, people lived through Ice Age winters with a fire, a bone needle, and each other. This video looks at what the evidence says about how they stayed warm, and how that story changed once farming arrived.
