Oh, I agree...but if two men were cooperating together, then they could succeed against one man who was an enemy. Most likely, socialization began with a man and woman together, with instincts.

I think it is reasonable to think that at some point 2 men realized that cooperating they could take down a dangerous animal, for food and safety.

Those humans that developed an instinct for socialization would naturally have a much higher chance of survival, and would pass-on these instincts...over the "lone wolf" human who would tend to die...hence there was a natural evolution of human socialization and community.
