Why humans run the world

History professor Yuval Noah Harari, author of Sapiens: A Brief History of Mankind, explains why humans have dominated Earth. The reason’s not what you might expect:

The real difference between us and other animals is on the collective level. Humans control the world because we are the only animal that can cooperate flexibly in large numbers. Ants and bees can also work together in large numbers, but they do so in a very rigid way. If a beehive is facing a new threat or a new opportunity, the bees cannot reinvent their social system overnight in order to cope better. They cannot, for example, execute the queen and establish a republic. Wolves and chimpanzees cooperate far more flexibly than ants, but they can do so only with small numbers of intimately known individuals. Among wolves and chimps, cooperation is based on personal acquaintance. If I am a chimp and I want to cooperate with you, I must know you personally: What kind of chimp are you? Are you a nice chimp? Are you an evil chimp? How can I cooperate with you if I don’t know you?

Only Homo sapiens can cooperate in extremely flexible ways with countless numbers of strangers. One-on-one or ten-on-ten, chimpanzees may be better than us. But pit 1,000 Sapiens against 1,000 chimps, and the Sapiens will win easily, for the simple reason that 1,000 chimps can never cooperate effectively. Put 100,000 chimps in Wall Street or Yankee Stadium, and you’ll get chaos. Put 100,000 humans there, and you’ll get trade networks and sports contests.
