Human evolution has favored groups because if you are not a 700-pound grizzly bear, there is safety in numbers. Groups work better if people cooperate in them, and generally aren't trying to hurt each other. To this end, people have a natural tendency to believe in something higher than themselves, whether it be God, or country, or family. Belief in something higher than oneself will cause a person to act not in his own self-interest, but in the interest of the group.
