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.

We have so far to go to realize our human potential for compassion, altruism, and love.

Your life matters. You can't live through a day without making an impact on the world. And what's most important is to think about the impact of your actions on the world around you.

Every individual can make a difference every day by making conscious choices.

A good mother is protective but not over-protective. She's patient, she's affectionate, she's playful, but above all she is supportive.

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.
