Query: Cro-Magnons had to deal with many problems...

Cro-Magnons may have outlived all the other early humans but they still had to fight against all the dangers stacked against them: the weather, large carnivores, and the prey which can be just as dangerous. We go from Europe, over the land bridge from Asia to America, following mankind as they develop new hunting skills, new tools and new ways of life. Nothing is sugar coated - a few hunters are shown being killed (but no REAL animals were harmed).Linda Hunt is the narrator for 'Mastering The Beasts', while John Slattery's voice is used for the 'How We Know What We Know' segments, with their timelines, maps, and archeological information. Lots of details within the 49 minutes but no extras on the DVD.
