Inspired by scientific theories about human history and evolution, this fascinating History Channel docudrama imagines what it would have been like if humankind's most likely ancestors, the Cro-Magnons, had lived side-by-side with the Neanderthals. While Cro-Magnons are smarter and more creative, Neanderthals are certainly stronger -- and their differences add up to a dramatic clash of brains vs. brawn.

It was an epic battle of brains versus brawn that determined the course of human history. In this scenario based on scientific theories, the viewer is taken back 30,000 years to the Ice Age in Europe when the Cro Magnon, our prehistoric ancestors, may have crashed with a completely different species of humans, the Neanderthals.

In Clash Of The Cavemen, cinematic re-creations and state-of-the-art CGI bring to life the Neanderthals - stocky, powerful and able to tolerate intense pain - and their foes, the Cro-Magnons - weaker and more fragile but with a superior brain capable of complex thought. This cinema-quality documentary from History re-creates the surroundings and dangers they endured: predators, punishing temperatures, and the unrelenting threat of starvation.

Cutting-edge archaeological and anthropological research, including data from the ongoing Neanderthal genome mapping project at Germany's Max Planck Institute, lends up-to-the-minute realism and accuracy to the cataclysmic fight to the finish.
