Neanderthal Human Wars
New study says the two hominid species fought for over 100,000 years. Perhaps the fight still continues today? Many people still carry Neanderthal and Denisovan genes. You can usually spot and identify them by the large flags they fly behind their pick up trucks.
The Neanderthals inherited the same genetic tendency that humans did, the facility for cooperative aggression.
War leaves a subtler mark in the form of territorial boundaries. The best evidence that Neanderthals not only fought but excelled at war, is that they met us and weren't immediately overrun. Instead, for around 100,000 years, Neanderthals resisted modern human expansion.
But indeed they met their match. In the long run we were meaner, smarter or bigger assholes. And we supposedly found, somewhere along the way, that kindness might be a better evolutionary strategy.
