Local circulation of elites punctuated by transregional mobility enabled steppe political consolidation in the Xiongnu nomadic state.

The Xiongnu polity (ca. 200 BC- 150 AD) emerged out of indigenous community-centered socio-political structures to forge a powerful state that commanded the Mongolian steppe and beyond. Underpinned by a highly mobile pastoralist population, accustomed to seasonally rhythmic moves and embedded in an equestrian culture that facilitated rapid transport over long-distances, it remains unclear precisely how the movement of commoners, local aristocrats and regional elites abetted the formation and organization of Xiongnu state structures.

Ancient Mongolian aurochs genomes reveal sustained introgression and management in East Asia.

Societies in East Asia have utilized domesticated cattle for over 5000 years, but the genetic history of cattle in East Asia remains understudied. Genome-wide analyses of 23 ancient Mongolian cattle reveal that East Asian aurochs and ancient East Asian taurine cattle are closely related, but neither are closely related to any modern East Asian breeds. We observe binary variation in aurochs diet throughout the early Neolithic, and genomic evidence shows millennia of sustained male-dominated introgression.

U5a1 Mitochondrial DNA Haplotype Identified in Eneolithic Skeleton from Shatar Chuluu, Mongolia.

The mitochondrial haplotype U5a1 was identified from an Eneolithic grave associated with the Afanasievo archaeological culture in Bayankhongor Province, Erdenetsogt Township, at the site of Shatar Chuluu. This is the earliest appearance of an mtDNA haplotype associated with modern European populations on the Mongol Steppe. This evidence demonstrations that people with "western" mtDNA lived on the Mongol Steppe east of the Altai Mountains before the Bronze Age and refutes the notion that the Altai Mountains were a substantial barrier to gene flow, and definitively expands the acknowledged range of the Afanasievo archaeological culture.
