How Can Chimpanzees Rule the World?

Yuval: What really makes us powerful is our ability to cooperate in very large numbers. How do we convince so many people who often don't know each other to cooperate? We invent some story that can be completely fictional as long as everybody believes the same story they can work together, Yuval says. The huge differences in how humans and chimpanzees behave must be then down to very tiny differences in our genes he adds.
