Chimpanzees, gorillas, orangutans also learn human sign language.

They can now sell part of those fruits to the orangutan project.

Having more than all the orangutans in all the zoos in the world together, just now like victims for every baby, six have disappeared from the forest.

It had a swooping banana seat and those ape hanger handlebars that made the rider look like an orangutan.

To put that into perspective, this red vertical bar here marks the divergence time of humans from chimpanzees, a mere seven million years ago.

So if we want to help the orangutans what I actually set out to do we must make sure that the local people are the ones that benefit.

This is a very beautiful species, it's called the Oriental Scarlet.

So birds do it too.

She's now living in the jungle of Sungai Wain, and this is Matahari, her second son, which, by the way, is also the son of the second orangutan I rescued, Dodoy.

Bonobos are built slightly smaller than the chimpanzee.

We have the zone with the sugar palms, and then we have this fence with very thorny palms to keep the orangutans that we provide with a place to live in the middle and the people apart.

(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.

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

So when you compare them to the Bonobo, the Bonobo is a little hairier.

Mr. Wurzel. The female has her first baby when she's 11 or 12.

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.

And the ones that stayed on in Africa evolved into the gorillas, the chimpanzees and us.

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

It has also chimpanzees.

He's a Bonobo.

You hear it going from one side of the valley to the other, from one group of nests to the next.

We have eight Bonobos.

Your father is a gorilla.

You see here the work of Ben Fry. This is Human vs. Chimps the few chromosomes that distinguish us from chimps.

He doesn't stand quite as upright.

And the gorilla can't speak. Why?

By piecing together a complex ecological puzzle, biologist Willie Smits has found a way to re grow clearcut rainforest in Borneo, saving local orangutans and creating a thrilling blueprint for restoring fragile ecosystems.

Because the chimps have a very promiscuous mating society.

Koko is not an ordinary gorilla.

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!

So here we are, a chimpanzee using a computer.

And you can come back out through the scary orangutan.

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

Try to imagine a gorilla performing the same maneuver, and you can see that, compared with gorilla, we are halfway to being shaped like a fish.

This shows the Bonobo compared to an australopithecine like Lucy.

It means star in Swahili.

In chimps, by age three, the brain is formed over 90 percent.

Ghosts, orangutans, hospitals..

Every chimpanzee has his or her own personality.

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

So who are we? Brothers of masculine chimps, sisters of feminine bonobos? We are all of them, and more.

Slim bodied, Bonobos are by nature very gentle creatures.

One discovery was that wild Bonobos often walk bidpedally.

They're as smart as chimpanzees in some respects.

Chimpanzee troops have different cultures in different troops.
