Modern descendants of Kyordyughen warrior (Yakutia, 4200 years before present) in populations of Far East

Abstract

A search for the modern descendants of the Neolithic population has been conducted using two datasets of Y-chromosome polymorphisms: literature data on the ancient population of Northeast Eurasia and our own data on 256 whole genomes of 11 indigenous peoples of the Russian Far East (Aleuts, Chukchi, Evens, Evenks, Itelmens, Koryaks, Nanais, Negidals, Nivkhs, Orochi, and Ulchi). Y-SNP analysis revealed that both Kyordyughen I (4200 YBP) and Kyordyughen II (4600 Y??) samples of the Yakutian Late Neolithic belong to the haplogroup N-L708 and lie on its two branches that diverged at 6200 YBP. A quarter (67 of 256) of the analysed samples, including Chukchi, Evens, Evenks, Itelmens, Koryaks, Nanais, Nivkhs, Orochi, and Ulchi, belong to the haplogroup N-L708 and are, to various extents, genetically related to the Neolithic Yakutian individuals. The most direct descendants of the famous Kyordyughen warrior (Kyordyughen I) are the indigenous peoples of Kamchatka and Chukotka (Chukchi, Koryaks, Evens). The divergence time of their Y-lineages (4300 ± 1000 Y??) is consistent with the radiocarbon dates for Kyordyughen I. Literary data on Y-STR polymorphism suggest that descendants of the Kyordyughen warrior dispersed far across North Asia. Ancient N-L708 carriers started to expand from Transbaikalia across Northeast Eurasia at ~7000 YBP. About 4000-3000 Y??, the lineages close to the Kyordyughen samples arrived in today’s Krasnoyarsk territory, Yakutia, Mongolia and Chukotka. Our findings are in good agreement with archaeological data and the autosomal genome-based modelling of the Kyordyughen warrior’s origin.
