To give just a sense of how different the emerging picture is: it is clear now that human societies before the advent of farming were not confined to small, egalitarian bands. On the contrary, the world of hunter-gatherers as it existed before the coming of agriculture was one of bold social experiments, resembling a carnival parade of political forms, far more than it does the drab abstractions of evolutionary theory. Agriculture, in turn, did not mean the inception of private property, nor did it mark an irreversible step towards inequality. In fact, many of the first farming communities were relatively free of ranks and hierarchies. And far from setting class differences in stone, a surprising number of the world’s earliest cities were organized on robustly egalitarian lines, with no need for authoritarian rulers, ambitious warrior-politicians, or even bossy administrators.
