Brains versus brawn. Go back 30,000 years to the Ice Age in Europe when the Cro Magnon may have clashed with a completely different species of humans, the Neanderthals. The Neanderthals were stocky, powerful and able to tolerate intense pain, while their foes, the Cro-Magnons were a weaker, more fragile species, but with a superior brain capable of complex thought.
