Louis [Leakey] was anxious to initiate a scientific study of these chimpanzees. It would be difficult, he emphasized, for nothing was known; there were no guidelines for such a field study; and the habitat was remote and rugged. Dangerous wild animals would be living there, and chimpanzees themselves were considered at least four times stronger than humans. I remember wondering what kind of scientist he would find for such a herculean task.

The least I can do is speak out for the hundreds of chimpanzees who, right now, sit hunched, miserable and without hope, staring out with dead eyes from their metal prisons. They cannot speak for themselves.

Every single day, we could be in a motorcar accident, so, we have to carry on with our lives, and not imagine terror around every corner.

My favorite animals are dogs.

I am living in the Africa I have always longed for, always felt stirring in my blood.

Terrorism is usually fueled by poverty, and the fanatical faith of the terrorists who truly believe that the more people they kill who do not subscribe to their faith, the greater their reward in heaven.

Certainly, if you look at human behavior around the world, you have to admit that we can be very aggressive.
