Earliest Known Rye Cultivation at Tell Abu Hureyra

Archaeological evidence from Tell Abu Hureyra in Syria reveals the earliest known deliberate cultivation of rye, dated to approximately 11,000 BCE. Paleobotanist Gordon Hillman identified domesticated rye grains significantly larger than wild varieties, indicating selective cultivation. This cultivation appears linked to the Younger Dryas climate event, which reduced wild food sources and prompted hunter-gatherers to actively grow cereal crops. The site provides some of the earliest verified evidence of intentional plant cultivation, predating widespread agricultural adoption in the Fertile Crescent.
