It has also chimpanzees.

Chimpanzees, for example, grow only 14 , with no pronounced spurt.

It's on altruism and chimpanzees where the question is, do chimpanzees care about the welfare of somebody else?

They're as smart as chimpanzees in some respects.

I've been studying chimpanzees in Tanzania since 1960.

Monkeys, chimps, just get rid of the hairy creatures.

Right? Who thinks you could beat the chimps?

In this case, we put two chimpanzees side by side.

And we find chimps are capable of true compassion and altruism.

Chimpanzees, killer whales, these kinds of creatures, they have culture.

Chimpanzee troops have different cultures in different troops.

None of them are close to where the chimps are.

Do they understand that as well as the chimps, for example?

Because the chimps have a very promiscuous mating society.

Farther back is there one shared with chimpanzees.

Chimpanzees don't have a spoken language. We've talked about that.

We know chimps are faster and stronger.

It has now been done with dogs and with birds and with chimpanzees.

Chimpanzees, gorillas, orangutans also learn human sign language.

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

And we study that in our chimpanzees by presenting them with an animated head.

So she gives us now a pro social token and both chimps get fed.

In this case, chimpanzees teaching each other how to crack nuts with rocks.

It's the question of, why are we so different from the chimpanzees?

The chimps are actually interacting with each other through the computers.

Just wire the chimps up to love that look, and apparently they do.

That is the call that chimpanzees make before they go to sleep in the evening.

And young chimpanzees spend a lot of time watching what their elders do.

Now these chimpanzees are using tools, and we take that as a sign of their intelligence.

It went unnoticed, because there has been no European medical research on chimpanzees since 2003.

And now you're going to get a more interesting picture, because now one of the two chimps has been fed.

We do that on chimpanzees that live in Lawrenceville, in the field station of Yerkes.

And we use GSI geographic whatever it is, GSI to determine the range of the chimps.

Over six million years, we and the chimps evolved our different ways.

Now, Jane Goodall has here a play face along with one of her favorite chimps.

So we're going to check that out by having the chimps actually play a game by touching two touch screens.

Close relatives of the human malaria parasites remain common in chimpanzees.

Now the funny thing is that Sarah Brosnan, who's been doing this with chimpanzees, had a couple of combinations of chimpanzees where, indeed, the one who would get the grape would refuse the grape until the other guy also got a grape.

I'm not sure how well the chimpanzees read it, but they surely seemed interested in the book.

So how humans and chimpanzees behave differently might tell us a lot about brain evolution.

Their hair is typically reddish brown, instead of the brown or black hair typical of chimpanzees and gorillas.

Female chimpanzees also have a hierarchy, which is influenced by the position of a female individual within a group.

And I discovered there that the chimpanzees are very power hungry and wrote a book about it.

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

The chimps are playing better than the humans, better in the sense of adhering to game theory.
