Liebenberg is a professional wildlife tracker who works with the Bushmen doing wildlife research. This lecture is a talk about how tracking may have lead to the development of human reason and imagination and the physical capacity for endurance running. I've studied tracking. It's been refereed to as the original CSI. To me stuff like tracking and Bird Language (https://www.youtube.com/watch?v=Oxzlap9FLIQ) goes right along with Marks Sisson's Primal Connections.
There's other videos from where I got the Lienbenberg lecture
