This National Geographic special is incredible. It looks at the Human Genographic Project and how we are all linked as homo sapiens from just a few relatives in Africa over 60,000 years ago.
We need to understand how inextricably linked we are as a species. We share over 99% genetic similarity!
I found it on Netflix but I’m sure you can get it from a library or watch it here on YouTube: http://www.youtube.com/watch?v=oRVhgJjJwTw
