These are baboons at a watering hole.

And Nick ended up with a lot of pictures of the rear ends of baboons.

After about one year, the young animals are weaned.

And it's important to remember that, because the bonobos are so human, and they share 99 percent of their genes with us.

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

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.

But as far as we know, we're the only upright walking ape that exists on planet Earth today, except for the bonobos.

But only when we saw the tiny baby baboon clinging to the mother's fur did we realize that something very unique was taking place here with Legadema.
