Bonobos are built slightly smaller than the chimpanzee.

Which, by chimpanzee standards, is very good indeed.

Chimpanzee troops have different cultures in different troops.

Every chimpanzee has his or her own personality.

So here we are, a chimpanzee using a computer.

I observe a chimpanzee peel a banana and eat it.

Approximately one letter in a hundred will differ from a chimpanzee.

Clearly, the chimpanzee has a little bit harder time of walking.

Let's get that one out of there. How about a chimpanzee?

Their brains are proportionate, in the same proportion as chimpanzee brains are.

So if we add in a chimpanzee here, we will see more differences.

Now this shows a Bonobo on your right, and a chimpanzee on your left.

In chimpanzee society, we find many, many examples of compassion, precursors to love and true altruism.

When we did the analysis of this bone, it was clear that it looked very chimp like, chimpanzee like.

The importance of learning in that time, when behavior is flexible and there's an awful lot to learn in chimpanzee society.

But in addition, if you compare the skull with a comparably aged chimpanzee and little George Bush here, you see that you have vertical forehead.

Now, I know that's a dirty word for some people, but we evolved from common ancestors with the gorillas, the chimpanzee and also the bonobos.

Because the chimpanzee would score half right if I gave them two bananas with Sri Lanka and Turkey. They would be right half of the cases.

Actually, that overwhelming similarity between human and chimpanzee DNA is a product of two cultural facts our familiarity with the chimpanzee s body, and our unfamiliarity with DNA. After all, when the chimpanzee itself was new and interesting (in the 1700 s), contemporary scholars commonly judged it to be overwhelmingly similar to the human form so much so, that it was commonly classified as a variant of humans.

The legendary chimpanzee researcher Jane Goodall talks about TACARE and her other community projects, which help people in booming African towns live side by side with threatened animals.

I did also an unethical study of the professors of the Karolinska Institute that hands out the Nobel Prize in Medicine, and they are on par with the chimpanzee there.

So if you were there 3.3 million years ago, to hear when this girl was crying out for her mother, she would have sounded more like a chimpanzee than a human.

And so, I want to give you a greeting, as from a chimpanzee in the forests of Tanzania Ooh, ooh, ooh, ooh, ooh, ooh, ooh, ooh, ooh, ooh, ooh, ooh, ooh, ooh, ooh!

I think the chimpanzee in captivity who is the most skilled in intellectual performance is one called Ai in Japan her name means love and she has a wonderfully sensitive partner working with her.

(a) The World Atlas of Great Apes and their Conservation which provides a comprehensive overview of what is currently known about all the six species of great apes chimpanzee, bonobo, Sumatran orangutan, Bornean orangutan, eastern gorilla and western gorilla.

And I was watching Jane Goodall yesterday, and I thought it was really great, and I was watching those incredible slides of the chimpanzees, and I thought, Wow. What if a chimpanzee could talk, you know? What would it say?

It's therefore probable that Africa was formerly inhabited by extinct apes closely allied to the gorilla and chimpanzee, and as these two species are now man's nearest allies, it's somewhat more probable that our early progenitors lived on the African continent than elsewhere.

Instead, performance capture technology, originally invented for the movie Avatar, enables a human actor, Andy Serkis, to play the role of the chimpanzee Caesar, not by dressing in a chimp suit, but by having every gesture and facial movement, even the twitch of an eyebrow, transformed into the movement of an ape.

And we believe that it's in this way that the different tool using behaviors that have now been seen in all the different chimpanzee populations studied in Africa how these are passed from one generation to the next, through observation, imitation and practice, so that we can describe these tool using behaviors as primitive culture.

Because a DNA sequence is a one dimensional entity, it lends itself much better to single number comparisons than a four dimensional body does. The genes that lead to the production of the human and chimpanzee femur may be 98 99 identical, but it is impossible to say whether the bones themselves are more or less similar than that.

And as I said, we don't know how hard that is. It might be after all, most other mammals live half as long as the chimpanzee, so we're sort of three and a half or four times, have four times the longevity of most mammals. And in the case of the primates, we have almost the same genes. We only differ from chimpanzees, in the present state of knowledge, which is absolute hogwash, maybe by just a few hundred genes.
