If a chimp who has been abused horribly by humans can help a human friend in a time of need, how much more should we help the animals - and other people for that matter - in their time of need?

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.

When you borrow you plan to pay back. We're stealing from our children - so many people have no intention of paying back.

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.

There are many people out there (me being one of them) who can vouch that animals have feelings; they feel compassion and love, as well as pain!

My family has very strong women. My mother never laughed at my dream of Africa, even though everyone else did because we didn't have any money, because Africa was the 'dark continent', and because I was a girl.

I think the most important thing is to keep active, and to hope that your mind stays active.
