The animals we raise for food today are eaten not because they are notably delectable or nutritious or a pleasure to be around, but because they were the ones first domesticated in the Stone Age. We are, in the most fundamental way, Stone Age people ourselves. From a dietary point of view, the Neolithic period is still with us. We may sprinkle our dishes with bay leaves and chopped fennel, but underneath it all is Stone Age food. And when we get sick, it is Stone Age diseases we suffer.
