Rajah Manchou Posted May 21, 2018 Posted May 21, 2018 (edited) From a new preprint presenting ancient DNA results from the Caucasus region: "We were surprised to discover that Steppe Maykop individuals from the eastern desert steppes harboured a distinctive ancestry component that relates them to Upper Palaeolithic Siberian individuals (AG3, MA1) and Native Americans. This is exemplified by the more commonly East Asian features such as the derived EDAR allele, which has also been observed in EHG from Karelia and Scandinavian hunter gatherers (SHG). The additional affinity to East Asians suggests that this ancestry does not derive directly from Ancestral North Eurasians but from a yet-to-be identified ancestral population in north-central Eurasia with a wide distribution between the Caucasus, the Ural Mountains and the Pacific coast, of which we have discovered the so far southwestern-most and also youngest (e.g. the Lola culture individual) genetic representative. The insight that the Caucasus mountains served not only as a corridor for the spread of CHG/Neolithic Iranian ancestry but also for later gene-flow from the south also has a bearing on the postulated homelands of Proto-Indo-European (PIE) languages and documented gene-flows that could have carried a consecutive spread of both across West Eurasia." (source) Notice how close the Bronze Age Maykop and Lola samples from this "yet-to-be-identified" population are to the Ojibwa found in the Great Lakes region. Edited May 21, 2018 by Rajah Manchou 2
