The process by which agriculture diffused from the Fertile Crescent within the past 10,000 years has been widely discussed, but as yet there is no consensus: Was it mostly a demic diffusion (with massive spread of peo-ple) or rather a cultural diffusion (without substantial migration of people)? The demic diffusion model (1) predicts a substantial ge-netic input from migrating agriculturalists, whereas the cultural diffusion model (2) pre-dicts no major changes at the genetic level. Hence, a way to test these competing hypoth-eses would be to compare genetic variation in traditional agriculturalists, traditional hunter-gatherers, and recent agriculturalists (i.e.,
