德國馬克斯普朗克人類史科學研究所Johannes Krause、Choongwon Jeong、Cosimo Posth等研究人員合作發現,舊石器時代到青銅時代的西伯利亞人與第一批美洲人接觸的證據。該項研究成果於2020年5月20日在線發表在《細胞》雜誌上。
據研究人員介紹,自舊石器時代晚期以來,現代人類就居住在貝加爾湖地區,儘管在很長一段時間內這些人的確切歷史仍然未知。
研究人員發現該西伯利亞地區的19個舊石器時代至青銅時代早期個體的全基因組數據。舊石器時代晚期的基因組通過共同的混合血統祖先產生所有非北極美洲原住民,這顯示出與原住民的直接聯繫。研究人員還證明了早在新石器時代和青銅時代貝加爾湖人口的形成是由於在整個八至六千年的長期混合。
此外,研究人員檢測了與西方歐亞草原群體的遺傳相互作用,並從兩個沒有西方歐亞血統的青銅時代早期個體中重建了鼠疫病基因組。
總體而言,這些研究表明,舊石器時代晚期的西伯利亞人與第一批美洲人之間存在最深遠的聯繫,並揭示了人類和病原體在青銅時代跨越歐亞大陸的流動性。

Abstract: Modern humans have inhabited the Lake Baikal region since the Upper Paleolithic, thoughthe precise history of its peoples over this long time span is still largely unknown.Here, we report genome-wide data from 19 Upper Paleolithic to Early Bronze Age individualsfrom this Siberian region. An Upper Paleolithic genome shows a direct link with theFirst Americans by sharing the admixed ancestry that gave rise to all non-Arctic NativeAmericans. We also demonstrate the formation of Early Neolithic and Bronze Age Baikalpopulations as the result of prolonged admixture throughout the eighth to sixth millenniumBP. Moreover, we detect genetic interactions with western Eurasian steppe populationsand reconstruct Yersinia pestis genomes from two Early Bronze Age individuals without western Eurasian ancestry.Overall, our study demonstrates the most deeply divergent connection between UpperPaleolithic Siberians and the First Americans and reveals human and pathogen mobilityacross Eurasia during the Bronze Age.
