The Case Against Civilization – Did our hunter-gatherer ancestors have it better?

In “Against the Grain: A Deep History of the Earliest States,” James C. Scott, a professor of political science at Yale, presents a plausible contender for the most important piece of technology in the history of man. It is a technology so old that it predates Homo sapiens and instead should be credited to our ancestor Homo erectus. That technology is fire. We have used it in two crucial, defining ways. The first and the most obvious of these is cooking. As Richard Wrangham has argued in his book “Catching Fire,” our ability to cook allows us to extract more energy from the food we eat, and also to eat a far wider range of foods. Our closest animal relative, the chimpanzee, has a colon three times as large as ours, because its diet of raw food is so much harder to digest. The extra caloric value we get from cooked food allowed us to develop our big brains, which absorb roughly a fifth of the energy we consume, as opposed to less than a tenth for most mammals’ brains. That difference is what has made us the dominant species on the planet.
