We present analyses of the genome of a ~34,000-year-old hominin skull cap discovered in the Salkhit Valley in northeastern Mongolia. We show that this individual was a female member of a modern human population that, following the split between East and West Eurasians, experienced substantial gene flow from West Eurasians. Both she and a 40,000-year-old individual from Tianyuan outside Beijing carried genomic segments of Denisovan ancestry. These segments derive from the same Denisovan admixture event(s) that contributed to present-day mainland Asians but are distinct from the Denisovan DNA segments in present-day Papuans and Aboriginal Australians.
我们对在蒙古国东北部的萨利赫特山谷发现的一个约 34000 年前的古人类头盖骨进行了基因组分析。我们发现，这位女性属于一个现代人种群，在东亚和欧洲人群分化之后，她的种群与欧洲人群有大量基因交流。她和北京田园洞的 4 万年前的个体都携带丹尼索瓦人祖先的基因组片段。这些片段来自于同样的导致现今亚洲大陆人群与丹尼索瓦人混血的事件，但与现今巴布亚人和澳大利亚原住民中的丹尼索瓦人 DNA 片段不同。
