Origins Of Agriculture In The Fertile Crescent — Farming Began In Several Places At Once, Research Finds
The exact origins of agriculture — if there are any which can be recognized in archaeological records — are something of a mystery. But now, new research has shed some further light on subject — the foothills of the Zagros Mountains of Iran in the eastern Fertile Crescent also served as a key center for early domestication along with the already known early plant domestication that took place in the western and northern Fertile Crescent.
Of course agriculture seems to have arisen independently across a wide variety of regions — and isn’t even unique to people, ants and termites both farm — so it’s an open question when it actually “began”? It’s entirely possible that agriculture of some kind was even present during earlier interglacial periods — though that is certainly not a popular idea in the field currently. As far as current theory is concerned, agriculture began in some regions sometime between 10,000-13,000 BC, in the Fertile Crescent of West Asia. (Authors note: It had previously been though that agriculture was the cause of a subsequent explosion in the world’s human population, but newer research has found that the population began growing rapidly far before agriculture is thought to have emerged.)
The new findings are the result of research done by the University of Tübingen, the Tübingen Senckenberg Center for Human Evolution and Paleoenvironment, and the Iranian Center for Archaeological Research.
Researchers Nicholas Conard and Mohsen Zeidi from the University of Tübingen led the investigations “at the aceramic tell site of Chogha Golan in 2009 and 2010. They documented an 8 meter thick sequence of exclusively aceramic Neolithic deposits dating from 11,700 to 9,800 years ago. These excavations produced a wealth of architectural remains, stone tools, depictions of humans and animals, bone tools, animal bones, and — perhaps most importantly — the richest deposits of charred plant remains ever recovered from the Pre-Pottery Neolithic of the Near East.”
The head of the archaeobotany laboratory at Tübingen — Simone Riehl — analyzed “over 30,000 plant remains of 75 taxa from Chogha Golan, spanning a period of more than 2,000 years. Her results show that the origins of agriculture in the Near East can be attributed to multiple centers rather than a single core area and that the eastern Fertile Crescent played a key role in the process of domestication.”
The University of Tübingen has more:
Many pre-pottery Neolithic sites preserve comparatively short sequences of occupation, making the long sequence form Chogha Golan particularly valuable for reconstructing the development of new patterns of human subsistence. The most numerous species from Chogha Golan are wild barley, goat-grass and lentil, which are all wild ancestors of modern crops. These and many other species are present in large numbers starting in the lowest deposits, horizon XI, dating to the end of the last Ice Age roughly 11,700 years ago. In horizon II dating to 9.800 years ago, domesticated emmer wheat appears.
The plant remains from Chogha Golan represent a unique, long-term record of cultivation of wild plant species in the eastern Fertile Crescent. Over a period of two millennia the economy of the site shifted toward the domesticated species that formed the economic basis for the rise of village life and subsequent civilizations in the Near East. Plants including multiple forms of wheat, barley and lentils together with domestic animals later accompanied farmers as they spread across western Eurasia, gradually replacing the indigenous hunter-gather societies. Many of the plants that were domesticated in the Fertile Crescent form the economic basis for the world population today.
The new research was published in the July 5 edition of the journal Science.
