If we're descended from chimpanzees, how come there are there still chimpanzees?

When we group chimpanzees together with, say, snakes, as animals, we imply that the gap between us and chimpanzees is greater than the gap between chimpanzees and snakes.

The Chimpanzees of Gombe Patterns of Behavior.

Well, we' re not descended from chimpanzees.

I discovered that chimpanzees reconcile after fights.

Now, chimpanzees are well known for their aggression.

I've been studying chimpanzees in Tanzania since 1960.

Chimpanzees, gorillas, orangutans also learn human sign language.

The Dutch government subsequently banned biomedical research on chimpanzees.

Bonobos are, together with chimpanzees, your living closest relative.

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

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