If we look straight and deep into a chimpanzee's eyes, an intelligent self-assured personality looks back at us. If they are animals, what must we be?

Male chimpanzees have an extraordinarily strong drive for dominance. They're constantly jockeying for position.

We would much rather blame nature for what we don't like in ourselves than credit it for what we do like.

The possibility that empathy resides in parts of the brain so ancient that we share them with rats should give pause to anyone comparing politicians with those poor, underestimated creatures.
