Recent research on the origins of domesticated herd animals and bronze metallurgy in China suggests that the Ejiin gol in western China was a primary conduit of trade between northern pastoralists and southern agriculturalists (Jaang, 2015). It is within the context of long-distance trade in luxury goods that we see the shift from isolated populations of pastoralists in the mountains of western Mongolia to the widespread adoption of pastoralist cultural traditions. Based on evidence of interaction between Gobi Desert groups and agrarian villages to the south, we see this desert region as the geographic core of cultural transformations among indigenous populations, and at the forefront of a third stage of advance in the spread of East Asian pastoralism. Evidence presented here for increased trade in luxury goods at the beginning of the second millennium BC, when production was at its height, combined with the rapid pace of transformations in burial culture during the mid-second millennium BC suggests that the movement of goods held extreme significance for the spread of pastoralism. Therefore, the role that Gobi Desert groups played in the formation of early trade networks is vital for understanding the spread of pastoralism in Mongolia. Here, we present new evidence for stone bead production and dairying in the Gobi Desert, and discuss the full range of evidence for the role of Gobi Desert groups in emerging long-distance trade networks.
