最近の考古遺伝学の研究により、彼らの起源が北モンゴルの異なる遊牧民族の急激な移住と混血によるものであることがわかったが、その結果は新たな疑問を呼び起こした。このため、国際チームは、西の辺境地帯にある2つの匈奴帝国の貴族・地元エリートの墓を遺伝学的に調査し、社会的組織化や富、権力、性別に関する遺伝的多様性の構造を調べた。

Abstract
The Xiongnu established the first nomadic imperial power, controlling the Eastern Eurasian steppe from ca. 200 BCE to 100 CE. Recent archaeogenetic studies identified extreme levels of genetic diversity across the empire, corroborating historical records of the Xiongnu Empire being multiethnic. However, it has remained unknown how this diversity was structured at the local community level or by sociopolitical status. To address this, we investigated aristocratic and local elite cemeteries at the western frontier of the empire. Analyzing genome-wide data from 18 individuals, we show that genetic diversity within these communities was comparable to the empire as a whole, and that high diversity was also observed within extended families. Genetic heterogeneity was highest among the lowest-status individuals, implying diverse origins, while higher-status individuals harbored less genetic diversity, suggesting that elite status and power was concentrated within specific subsets of the broader Xiongnu population.
