Sites of food production before 7 000 B C E7,000 B.C.E. The geographical distribution of the seven Neolithic founder crops in the Fertile Crescent (yellow) of the Near East. Large map shows the distribution of wild chickpea (red line) in a core area (green line) within the upper reaches of the Tigris and Euphrates rivers (present dayreaches of the Tigris and Euphrates rivers (present-day southeastern Turkey/northern Syria). Inset maps show the distribution of founder cereal crops — einkorn wheat (cross indicates the putative site of its domestication), emmer wheat, and barley — and founder legumes (lentil, pea, bitter vetch). Blue lines delineate the range of genetic founder stocks for lentil and pea, and red lines g p ,the range of emmer wheat, barley, and bitter vetch (no data are available on their genetic founder stocks). Red lines also indicate the distribution of einkorn wheat, lentil, and pea beyond that of their genetic founder stocks.
