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".

In Africa, we have the bush meat trade, which means that, on a very large scale, animals are being killed in the forests and sold in the cities as a luxury food.

Most exotic animals are not particularly interested in people, which makes it hard to provoke them. Human-rearing gets them used to and sometimes imprinted on humans, which makes them potentially dangerous.

Female bonobos form a strong sisterhood. They rule through female solidarity.

To endow animals with human emotions has long been a scientific taboo. But if we do not, we risk missing something fundamental, about both animals and us.

Perhaps it's just me, but I am wary of any persons whose belief system is the only thing standing between them and repulsive behavior.

Humanity is actually much more cooperative and empathic than [it's] given credit for.
