John Lanchester at The New Yorker:
It turns out that hunting and gathering is a good way to live. A study from 1966 found that it took a Ju/’hoansi only about seventeen hours a week, on average, to find an adequate supply of food; another nineteen hours were spent on domestic activities and chores. The average caloric intake of the hunter-gatherers was twenty-three hundred a day, close to the recommended amount. At the time these figures were first established, a comparable week in the United States involved forty hours of work and thirty-six of domestic labor. Ju/’hoansi do not accumulate surpluses; they get all the food they need, and then stop. They exhibit what Suzman calls “an unyielding confidence” that their environment will provide for their needs.
The web of food sources that the hunting-and-gathering Ju/’hoansi use is, exactly as Scott argues for Neolithic people, a complex one, with a wide range of animal protein, including porcupines, kudu, wildebeests, and elephants, and a hundred and twenty-five edible plant species, with different seasonal cycles, ecological niches, and responses to weather fluctuations. Hunter-gatherers need not only an unwritten almanac of dietary knowledge but what Scott calls a “library of almanacs.” As he suggests, the step-down in complexity between hunting and gathering and domesticated agriculture is as big as the step-down between domesticated agriculture and routine assembly work on a production line.
