We are territorial, power-hungry and even more brutal than chimpanzees.

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.

We would much rather blame nature for what we don't like in ourselves than credit it for what we do like.

When it comes to social interaction, the chimpanzees appear to be just as intelligent as we are.

Human morality is unthinkable without empathy.

Religion may have become a codification of morality, and it may fortify it, but it's not the origin of it.

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".
