Even when it comes to things like wars over oil, which may seem like a whole different ball game, there are still comparisons one can draw: chimps fight for their territory; they fight for the resources within that territory, so it does relate in a way.

Chimps are brutal, and it is so deliberate. The males go out and get near the boundary of their territory. And they walk very silently trying hard not to make any noise. They will climb into a tree and stare out over hostile territory for hours. They are waiting for the right opportunity. And then they attack.

I think the best evenings are when we have messages, things that make us think, but we can also laugh and enjoy each other's company.

I don't think that faith, whatever you're being faithful about, really can be scientifically explained. And I don't want to explain this whole life business through truth, science. There's so much mystery. There's so much awe.

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!

My mission is to create a world where we can live in harmony with nature. And can I do that alone? No. So there is a whole army of youth that can do it. So I suppose my mission is to reach as many of those young people as I can through my own efforts.

Just think of the trust that often exists in soldiers. Within their own unit, you could say they have to trust each other. A spirit of camaraderie builds up and, in the end, they will risk their lives for each other. They may even go so far as to dehumanise the other, enemy group - a mechanism you can also observe in chimps.
