If you find anthropology fascinating then your next two hours should be spent watching 'The Journey of Man: A Genetic Odyssey'. This documentary talks about our evolution and recent history. It explores the question of why humanity was able to go from the brink of extinction in Northern Africa to dominating the far reaches of the globe in such a relevantly short time. The documentary delves into humanities history through the science of genetics. Recently scientists have been recording genetic mutations called markers in the 'Y' chromosome that its passed down through generation after generation of males with out being rearranged with both parents gens which allows them to track our ancestors movements throughout time with our current blood. Its a fascinating idea which has led to a very accurate description of how and when we spread out across the world and actually allowed us to find the surviving members of the Bushman who's ancestors initially left Africa and spread out across the world. They kinda look nonracial. Weird.
