The power of freedom

There are many theories, but very little evidence, about why the Neanderthals became extinct. Some Anthropologists think there was a genocide and the Humans simple exterminated the Neanderthals the encountered as they moved out of Africa, some think that Humans and Neanderthals breed and so eventually the Neanderthals simply became absorbed into the Human race, others think that Humans more flexable brains ment that they simply out competed them in hunting and they where selected out in the Darwinian fassion as less well adapted (there is some evidence against this one). However there is a new theory that free trade may have finished off Neanderthals, it is only really supported by computer modelling at the moment but an interesting result anyway.
