https://youtu.be/gn4bvjMh4vc is a TED Talk by Michael Robinson, who has a couple of books worth learning about regarding the Arctic and Africa, and the peoples from those places long ago. A friend using my computer had the talk up and before cancelling out, I figured I'd see what it's about. What are some of your latest TED (Technology, Education and Design) talks of interest?
On npr.org there's The TED Talk Radio Hour that has a theme I heard of today as well.
