Moseley believes that Aspero, which has never been fully excavated, is older than the other cities, and set the template for them. “For archaeology,” deFrance said, “what may be important” in the end is not the scope of the society “but where it emerged from and the food supply. You can’t eat cotton.” Evidence one way or the other may emerge if Moseley and Shady, as planned, return to Aspero. If they are correct, and Aspero turns out to be substantially older than now thought, it might win the title of the world’s oldest city—the place where human civilization began.
