was thought that settling down—sedentism, as it is known—and farming went hand in hand. People, it was assumed, abandoned nomadism and took up farming in order to guarantee their food supplies. Killing wild game is difficult and chancy, and hunters must often have come home empty-handed. Much better to control your food sources and have them permanently and conveniently at hand. In fact, researchers realized quite early on that sedentism was not nearly as straightforward as that. At about the time that Childe was excavating at Skara Brae, a Cambridge University archaeologist named Dorothy Garrod, working in Palestine at a place called Shuqba, discovered an ancient culture that she dubbed the Natufian, after a wadi, or dried riverbed, that lay nearby. The Natufians built the first villages and founded Jericho, which became the world’s first true city. So they were very settled people. But they didn’t farm. This was most unexpected. However, other excavations across the Middle East showed that it was not uncommon for people to settle in permanent communities long before they took up farming—sometimes by as much as eight thousand years.

So if people didn’t settle down to take up farming, why then did they embark on this entirely new way of living? We have no idea—or actually, we have lots of ideas, but we don’t know if any of them are right. According to the historian Felipe Fernández-Armesto, at least thirty-eight theories have been put forward to explain why people took to living in communities: that they were driven to it by climatic change, or by a wish to stay near their dead, or by a powerful desire to brew and drink beer, which could only be indulged by staying in one place. One theory, evidently seriously suggested (Jane Jacobs cites it in her landmark work of 1969, The Economy of Cities), was that “fortuitous showers” of cosmic rays caused mutations in grasses that made them suddenly attractive as a food source. The short answer is that no one knows why agriculture developed as it did.

Making food out of plants is hard work. The conversion of wheat, rice, corn, millet, barley, and other grasses into staple foodstuffs is one of the great achievements of human history, but also one of the more unexpected ones. You have only to consider the lawn outside your window to realize that grass in its natural state is not an obvious foodstuff for nonruminants such as ourselves. For us, making grass edible is a challenge that can be solved only with a lot of careful manipulation and protracted ingenuity. Take wheat. Wheat is useless as a food until made into something much more complex and ambitious like bread, and that takes a great deal of effort. Somebody must first separate out the grain and grind it into meal, then convert the meal into flour, then mix that with other components like yeast and salt to make dough. Then the dough must be kneaded to a particular consistency, and finally the resulting lump must be baked with precision and care. The scope for failure in the last step alone is so great that in every society in which bread has featured, baking has been turned over to professionals from the earliest stages.

It is not as if farming brought a great improvement in living standards either. A typical hunter-gatherer enjoyed a more varied diet and consumed more protein and calories than settled people, and took in five times as much vitamin C as the average person today. Even in the bitterest depths of the ice ages, we now know, nomadic people ate surprisingly well—and surprisingly healthily. Settled people, by contrast, became reliant on a much smaller range of foods, which all but ensured dietary insufficiencies. The three great domesticated crops of prehistory were rice, wheat, and maize, but all had significant drawbacks as staples. As the journalist John Lanchester explains: “Rice inhibits the activity of Vitamin A; wheat has a chemical that impedes the action of zinc and can lead to stunted growth; maize is deficient in essential amino acids and contains phytates, which prevent the absorption of iron.” The average
