Researchers find it very necessary to keep blinkers on. They don't want to admit that the animals they are working with have feelings.

You have to realise that touching is a real violation of personal space.

We now know that the structure of the DNA in humans and chimpanzees differs by only just over one percent. You could even have a blood transfusion from a chimp, provided you have the same blood group.

We're the ones who can make a difference. If we lead lives where we consciously leave the lightest possible ecological footprints, if we buy the things that are ethical for us to buy and don't buy the things that are not, we can change the world overnight.

It was because the chimps are so eye-catching, so like us and teach us so much that my work was recognised worldwide.

Being evil is something that only humans are capable of.
