Michael D. Frachetti speaks on the East/West Diffusion of Domesticated Grains along the Inner Asian Mountain Corridor at the Silk Road Symposium held at the Penn Museum held in March 2011. Inner Asia has commonly been conceived as a region of Nomadic societies surrounded by agricultural civilizations throughout Antiquity. Societies of China, SW Asia, and Eastern Europe each developed agriculture in the Neolithic, while the earliest evidence for agriculture from the Eurasian steppe shows it was not a major part of local economies until the Iron Age (c. 700 BC). Newly discovered botanical evidence of ancient domesticated wheat and millet at the site of Begash in Kazakhstan, however, show that mobile pastoralists of the steppe had access to domesticated grains already by 2300 BC and that they were likely essential to the diffusion of wheat into China, as well as millet into SW Asia and Europe in the mid-3rd millennium BC. Currently, Begash provides the only directly dated botanical evidence of these crisscrossed channels of interaction. Whatsmore, the seeds from Begash were found in a ritual cremation context rather than domestic hearths. This fact may suggest that the earliest transmission of domesticated grains between China and SW Asia was sparked by ideological, rather than economic forces. This paper describes the earliest known evidence of wheat in the Eurasian steppes and explores the extent of ritual use of domesticated grains from China to SW Asia, across the Inner Asian mountains.
