Origins of Genus Homo: What Who When Where?
An interesting hour-long symposium on the origins of the genus homo. That includes us! And the story is complicated! Presented by University of California TV, it features 3 different scientists looking at different aspects of human evolution. Lots of good stuff in this lecture. You can see how scientists change their minds when research uncovers new data.
It would be well worth your while to subscribe to their youtube channel.
