Wheat
Einkorn wheat is one of the earliest cultivated forms of wheat, (Triticum monococcum). Grains of wild einkorn have been found in Paleolithic sites of the Fertile Crescent. It was first domesticated about 7500 BC (~9000 years ago), in the early Neolithic period.  Evidence from DNA suggests einkorn was domesticated in southeast Turkey, where a number of early farming villages have been found.  Its cultivation decreased in the Bronze Age, and today it is a relic crop that is rarely planted. It has found a new market as a health food. It is still used for bulgur (cracked wheat) or as animal feed, in mountainous areas of France, Libya, former Yugoslavia, Turkey and other countries. It often survives on poor soils where other species of wheat fail.
