Guns, Germs and Steel
Diamond believes that farming was important because humans had to start farming before they could invent things like cities, metal, the wheel and writing. Farming led to humans living in larger groups, so they had to form more complicated societies. They began to live in countries rather than tribes. In a farming society, not everyone may work on a farm. Some people can do other jobs, like rulers, writers and inventors, because there is so much food. The societies with the best farming were the ones that were more likely to have inventors. This is different to a hunter-gatherer society, where everyone must help find food.
