The oldest known cereal cultivation dates back 13000 years

The Abu Hureyra site houses the oldest known evidence of a cultivated plant in the world. During the Younger Dryas, faced with a lower diversity of consumed plants and environmental stress, the inhabitants developed proto-agriculture. Three rye grains presenting a domestic morphology were thus identified there and dated to approximately 13/12000 BP, while generalized domesticated rye only appeared 2000 years later.
