>Also, it is probably reasonable to assume the same "morals" the kept a group of hunter gatherers together are today responsible to racism and hate between groups. Good point. It's important to remember that evolution (including of the cultural variety) ultimately selects for survival. If group A is super happy and peaceful, and group B is unhappy and violent, if group B uses its capacity for violence to conquer group A then ultimately it will be group B's genetic/cultural traits that survive into the future.
