Chimps act the way they feel unless they are afraid of reprisal if they do so. But that doesn't apply to humans.

We, as humans, have actually developed a sense of social responsibility. We have gone beyond our basic instincts. We can and we do. This is what sets us apart from the chimps. They are extremely brutal and hostile. Your next door neighbor is to be killed unless she is a juicy young female, who hasn't yet had her first baby, in which case you want her.

Our brain is almost the same as the chimps', but we have language, we have electronic communications, we've put people on the moon - we are immensely more intelligent. And yet: how come the being with the most extraordinary intellect ever is destroying its only planet?

I believe that we have more capability than any other creature to control our biological inheritance - and we do so most of the time.

I think anything is better than war. The extent to which one can negotiate with fanatics, I have no idea. I don't know.

We have language and they do not. Chimps communicate by embracing, patting, looking - all these things. And they have lots of sounds. But they cannot sit and discuss. They cannot teach about things that are not present, as far as we know.

One individual cannot possible make a difference, alone. It is individual efforts, collectively, that makes a noticeable difference - all the difference in the world!
