| "Our analysis of DNA from the Yamnaya [Yamna] -- led by Iosif Lazaridis in my laboratory -- showed that they harbored a combination of ancestries that did not previously exist in Central Europe. The Yamnaya were the missing ingredient, carrying exactly the type of ancestry that needed to be added to early European farmers and hunter-gatherers to produce populations with the mixture of ancestries observed in Europe today. Our ancient DNA data also allowed us to learn how the Yamnaya themselves had formed from earlier populations. From 7K to 5K years ago [3K BCE], we observed a steady in-flux into the steppe of a population whose ancestors traced their origin to the South -- as it bore genetic affinity to ancient and present-day people of Armenia and Iran -- eventually crystallizing in the Yamnaya, who were about a one-to-one ratio of ancestry from these two sources. A good guess is that the migration proceeded via the Caucasus isthmus between the Black and Caspian seas. Ancient DNA data produced by Wolfgang Haak, Johannes Krause, and their colleagues have shown that the populations of the Northern Caucasus had ancestry of this type continuing up until the time of the Maikop [Maykop] culture, which just preceded the Yamnaya... Not only did the Maikop [Maykop] pass on to the Yamnaya [Yamna] their technology of carts, but they were also the first to build the kurgans [burial mounds] that characterized the steppe cultures for thousands of years afterward. The penetration of Maikop lands by Iranian- and Armenian-related ancestry from the South is also plausible in light of studies showing that Maikop goods were heavily influenced by elements of the Uruk civilization of Mesopotamia to the South, which was poor in metal resources and engaged in trade and exchange with the North as reflected in Uruk goods found in settlements of the Northern Caucasus. Whatever cultural process allowed the people from the South to have such a demographic impact, once the Yamnaya formed, their descendants expanded in all directions." --- David Reich & Eugenie Reich 2018 _Who We Are and How We Got Here: Ancient DNA & the New Science of the Human Past_ pp108-109 |
