Although dairy pastoralism once made Mongolian steppe herders successful enough to conquer most of Asia and Europe, the origins of this way of life on the East Asian steppe are still unclear. Now an international team of researchers led by the Max Planck Institute for the Science of Human History has uncovered evidence that dairying arrived in Mongolia as early as 1300 BC through a process of cultural transmission rather than population replacement or migration.

Two thousand years before the armies of Ghengis Khan, populations in Mongolia were already living a pastoralist, dairying lifestyle -- similar to that which would enable future populations to conquer most of Asia and Europe. Although pastoralism has long been the primary means of subsistence on the East Asian steppe, the origins of this tradition have been unclear. Now, an international team of researchers has uncovered the earliest direct evidence to date of dairying in Mongolia -- around 1300 BC -- by tracking milk proteins preserved in tooth tartar. The livestock that were milked -- cattle, sheep and goats -- are not native to the region and were likely introduced by Western Steppe herders. However, ancient DNA evidence from Bronze Age Mongolians indicates minimal genetic contributions from Western Steppe herders, suggesting that the livestock and dairying technologies were transferred by cultural processes rather than a major population migration, in contrast to the pattern seen in Europe. The findings are published in PNAS.
