If you gauge success by sheer numbers, chickens are unmatched. They were nonexistent 8000 years ago, at the dawn of agriculture. Then they were domesticated from wild jungle fowl and today there are something like 26 billion of them. They’re more abundant than any other bird and there are four chickens for every human. If you were a jungle fowl living 8000 years ago, do you think you would choose the path to “success,” or would you decide to stay in the jungle?
