Male chimpanzees have an extraordinarily strong drive for dominance. They're constantly jockeying for position.

Females avoid conflict. They are afraid of violence. The males, on the other hand, are less averse to strife. But once conflict breaks out, the males are much better at reconciling. In a study done in Finland, children who had quarreled were asked how much longer they intended to be angry at one another. The boys proudly said: "Oh, at least one or two days." The girls said "forever".

Why not assume that our humanity, including the self-control needed for livable societies, is built into us? Does anyone truly believe that our ancestors lacked social norms before they had religion? Did they never assist others in need, or complain about an unfair deal? Humans must have worried about the functioning of their communities well before the current religions arose, which is only a few thousand years ago.

As far as the environment is concerned, I am becoming pessimistic because I do not see anybody stepping up and taking the long view approach. It seems like we're stuck in a tragedy of the commons where everyone is trying to contribute as little as possible to get out of this situation.

Although elephants are far more distantly related to us than the great apes, they seem to have evolved similar social and cognitive capacities.

Exclusive homosexuality is not very common in nature.
