The change from hunting and gathering to agriculture during the Neolithic Revolution was a watershed in world history. The societies that first made the change to agriculture are believed to have lived in North Africa and Middle East around 10,000 BCE. Agriculture was introduced into Europe by migrating farmers from the Middle East. According to the demic diffusion model, these Middle Eastern farmers either replaced or interbred with the local hunter-gather populations that had been living in Europe since the "out of Africa" migration.
