Radiocarbon dating of the archaeological deposits, some 8 meters in depth, showed that Chogha Golan had been occupied continuously between about 12,000 and 9,700 years ago or even later . That allowed Riehl and her colleagues to trace the use of plants over that entire period of time. They found that the people of Chogha Golan apparently began cultivating wild barley, wheat, and lentils more than 11,500 years ago, and that domesticated forms of wheat appeared about 9,800 years ago, nearly as early as at sites to the west. The team concludes that the advent of farming at Chogha Golan, and in the eastern Fertile Crescent, was an independent event that paralleled developments much farther west.
This suggests, researchers say, that farming was more or less inevitable once the Ice Age had ended and climatic and environmental conditions were
"These results do support the idea of multiple origins of agriculture," says Roger Matthews, an archaeologist at the University of Reading in the United Kingdom. He adds that the findings are consistent with recent DNA studies that also suggest multiple origins for both domesticated plants and animals. They also echo work that he, along with other British and Iranian archaeologists, has carried out at another Iranian site called Sheikh-e Abad, where it appears that wild goats were herded and penned, "a transitional stage between wild and domesticated that matches well with the transitional stages in plant use" found at Chogha Golan.
George Willcox, an archaeobotanist affiliated with the University of Lyon in France, agrees that the geographical distance of the Zagros Mountains from the western Fertile Crescent could suggest an independent origin for crop cultivation. But he cautions that "it is too early to argue one way or the other" whether the actual domestication of cereals, as opposed to cultivation of wild forms, was an independent event. It is still possible, Willcox says, that the domesticated wheat found at Chogha Golan, which at 9800 years was several hundred years younger than the earliest known domesticated species, was introduced from further west.
