My mother always used to say, 'Well, if you had been born a little girl growing up in Egypt, you would go to church or go to worship Allah, but surely if those people are worshipping a God, it must be the same God' - that's what she always said. The same God with different names.

I miss the early days; I do. I was so lucky. I basically had it to myself, learning about these chimpanzees. Nobody knew anything about them. Discovering their different personalities, different life histories. I was lucky.

I didn't want to become a professor or get tenure or teach or anything. All I wanted to do was get a degree because Louis Leakey said I needed one, which was right, and once I succeeded I could get back to the field.

The chimpanzee study was - well, it's still going on, and I think it's taught us perhaps more than anything else to be a little humble; that we are, indeed, unique primates, we humans, but we're simply not as different from the rest of the animal kingdom as we used to think.

You don't turn out as many books as I did then by sitting around, being cozy with the family.

The books that stuck with me most as a child were 'A Wrinkle In Time', 'Dracula', 'Hatchet', 'Bunnicula', 'White Fang', and this YA/kids' book called 'Nobody's Fault' where a kid drowns one weekend as friends play around a flooded ditch.

I get asked a lot what books I recommend for a nursery, home library, etc., and I always tell parents to start with what they loved as children, what they want to share, and broaden out from there.

I come from a family of all women and one boy, my brother. We're all women and we're all precocious and opinionated and like to have fun and we always had friends in the house and we were always, like, half-naked.
