Primates are very territorial. It is in their nature to protect their food resources as well as their females and young.

It's the bond between mother and child, which is really for us and for chimps and other primates, the root of all the expressions of social behavior.

Chimps are very quick to have a sudden fight or aggressive episode, but they're equally as good at reconciliation.

In what terms should we think of these beings, nonhuman yet possessing so very many human-like characteristics? How should we treat them? Surely we should treat them with the same consideration and kindness as we show to other humans; and as we recognize human rights, so too should we recognize the rights of the great apes? Yes.

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.

The least I can do is speak out for those who cannot speak for themselves.

We are beginning to learn that each animal has a life and a place and a role in this world. If we place compassion and care in the middle of all our dealings with the animal world and honor and respect their lives, our attitudes will change.
