Nature：东亚人群也有至少5-10%的西欧亚成分？

David Reich实验室昨天新发nature论文解析最早的农民：Genomic insights into the origin of farming in the ancient Near East
We report genome-wide ancient DNA from 44 ancient Near Easterners ranging in time between ~12,000 and 1,400 BCE, from Natufian hunter–gatherers to Bronze Age farmers. We show that the earliest populations of the Near East derived around half their ancestry from a ‘Basal Eurasian’ lineage that had little if any Neanderthal admixture and that separated from other non-African lineages before their separation from each other. The first farmers of the southern Levant (Israel and Jordan) and Zagros Mountains (Iran) were strongly genetically differentiated, and each descended from local hunter–gatherers. By the time of the Bronze Age, these two populations and Anatolian-related farmers had mixed with each other and with the hunter–gatherers of Europe to drastically reduce genetic differentiation. The impact of the Near Eastern farmers extended beyond the Near East: farmers related to those of Anatolia spread westward into Europe; farmers related to those of the Levant spread southward into East Africa; farmers related to those from Iran spread northward into the Eurasian steppe; and people related to both the early farmers of Iran and to the pastoralists of the Eurasian steppe spread eastward into South Asia.
 
爆点在于最后一部分模拟东亚人群里的西欧亚成分：no less than ~5–10% ANE in diverse East Asian groups including Han Chinese，这里的ANE指的是西伯利亚的Mal'ta1，这直接颠覆了我们对史前人群混合的理解，但所用方法、所做假设是否正确就还需要后续验证。
