In the past few years, genetics have confirmed that the hunter-gatherers were not overwhelmed by the new wave of sedentary farmers, and that the first agricultural revolution spread well in advance of its first users, by contact and trade in ideas. Nice to see science catching up with economics and military history. Any economist could tell you technology spreads beyond its first adopters, even if they stay at home. And any military historian could tell you that, in a contest between people who hunt and kill aurochs and farmers armed with hoes, the smart money is on the hunters.
