It made me feel particularly sickened to know that this kind of callous attitude toward animals is repeated again and again in laboratories around this country.

If we start with chimpanzees, they differ from us with the composition of the DNA by only just over one percent. So, as far as genetics go, we're almost identical. The composition of the blood, the immune system, the structure of the brain - almost identical.

I wasn't trying to be a scientist. I only ever wanted to be a naturalist, like a David Attenborough.

The only possible way to get somebody to change is to reach into their hearts.

People say to me so often, 'Jane how can you be so peaceful when everywhere around you people want books signed, people are asking these questions and yet you seem peaceful,' and I always answer that it is the peace of the forest that I carry inside.

For those who have experienced the joy of being alone with nature there is really little need for me to say much more; for those who have not, no words of mine can ever describe the powerful, almost mystical knowledge of beauty and eternity that come, suddenly, and all unexpected.

The best relationship you can have with a chimpanzee is total mutual trust.
