Oat

The oat is a cereal grass grown for its seed and for fodder, valued for thriving in cool, wet climates that punish wheat. Wild oat grains have been found in a Pre-Pottery Neolithic granary in the Jordan Valley dated to roughly 11,200 to 11,400 years ago, but true domestication lagged well behind that early gathering: domesticated oat grains do not appear in Europe's archaeological record until about 3,000 years ago, arriving there as a secondary crop before becoming a deliberate planting in its own right.
