There is no sharp line between humans and animals. You can get a blood transfusion from a chimp, but not from a gorilla.
A top chimpanzee male can keep his position for four or five years, sometimes up to ten years.
His close friends are scheming to overthrow him. One of them will eventually succeed and can take over the leadership of the flock. The old king is beaten up and exiled.
The flock is happy to have a new leader who can guide them.
Chimpanzees live in hierarchical societies. There are upper-class, middle-class, and underclass chimpanzees.
War against neighboring flocks is commonplace.
Humans have inherited war and aggression from our ancestors, as well as love and compassion.
We can teach our children about things that don't exist, or might exist, and talk about the past and the future. Chimps don't understand anything about such matters.
Evolution has brought us here to the bitter end. Endless wars, the nuclear arms race, climate change, and pollution will soon make us go extinct. We are living in the end times.
