One chimp is called a matcher.

They want to press the opposite screen of the chimp.

Let's see how they can do it. This is a young chimp.

I put up a somewhat dour Darwin, but a very happy chimp up there.

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

And as you can see, the chimps, each chimp is one triangle, are circled around, hovering around that prediction.

And yet, when you look at the phenotypes, there's a chimp, there's a man they're astoundingly different, no resemblance at all.

The number and order of these four bases determine for example, whether you're a chimp, a cow, a banana, or a human.

What you have here is two young chimpanzees who have a box, and the box is too heavy for one chimp to pull in.

One is that the chimp on the right has a full understanding he needs the partner so a full understanding of the need for cooperation.

The chimp is going to see, watch carefully, they're going to see 200 milliseconds' exposure that's fast, that's eight movie frames of numbers one, two, three, four, five.

So if this chimp makes the selfish choice, which is the red token in this case, he needs to give it to us, we pick it up, we put it on a table where there's two food rewards, but in this case, only the one on the right gets food.
