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

Chimpanzees can be quite political.

I do not want to discuss evolution in such depth, however, only touch on it from my own perspective: from the moment when I stood on the Serengeti plains holding the fossilized bones of ancient creatures in my hands to the moment when, staring into the eyes of a chimpanzee, I saw a thinking, reasoning personality looking back. You may not believe in evolution, and that is all right. How we humans came to be the way we are is far less important than how we should act now to get out of the mess we have made for ourselves.

My mission is to create a world where we can live in harmony with nature. And can I do that alone? No. So there is a whole army of youth that can do it. So I suppose my mission is to reach as many of those young people as I can through my own efforts.

It's the bond between mother and child, which is really for us and for chimps and other primates, the root of all the expressions of social behavior.

When I look back over my life it's almost as if there was a plan laid out for me - from the little girl who was so passionate about animals who longed to go to Africa and whose family couldn't afford to put her through college. Everyone laughed at my dreams. I was supposed to be a secretary in Bournemouth.

Chimps are very quick to have a sudden fight or aggressive episode, but they're equally as good at reconciliation.
