Chimpanzees are incredibly intelligent. They can learn more than 400 signs of American Sign Language. They have memories for spatial distribution, like numbers on a TV screen, way better than ours. You come onto the emotions: happiness, sadness, fear, and despair - all the things for which I was accused of being anthropomorphic when I ascribed them to chimpanzees.

If you educate women, family size tends to go down.

Animals are as deserving of a place on this planet as we are, and the difference between us is that humans have a voice they can use to help the animal cause, and it is up to all of us to use it to make a positive difference!

Certainly the first true humans were unique by virtue of their large brains. It was because the human brain is so large when compared with that of a chimpanzee that paleontologists for years hunted for a half-ape, half-human skeleton that would provide a fossil link between the human and the ape.

Some people actually do not like animals - hard for me to understand, but true.

I don't even think of chimps as animals. I think of them as beings.

I shouldn't have named the chimps. It wasn't scientific. I didn't know. I knew nothing. And worse sin of all was that I was ascribing to them emotions like happiness, sadness and so forth.
