以色列铜器时代洞穴古人DNA，揭示人口混合如何推动文化转型。

研究从以色列Peqi'in洞穴出土的22具晚期铜器时代人骨中提取了全基因组古DNA。他们属于一个同质人群，其血统约57%来自黎凡特新石器人群，约17%来自伊朗铜器时代人群，约26%来自安纳托利亚新石器人群。这说明当时发生了大规模人口混合，而这种混合很可能促成了当地独特的文化变迁。

Peqi'in人群是一个同质群体，由三股不同来源的血统混合而成。
其血统构成约为57%黎凡特新石器、17%伊朗铜器时代和26%安纳托利亚新石器。
该人群对后来青铜时代群体的贡献不同，其中一个青铜时代群体不可能直接源自Peqi'in人群。

样本解读

站内统计显示，22个样本全部属于晚期铜器时代。其中10个样本成功解析了Y染色体单倍群，以T系为主：T-Y4119有3例，T-L208有3例，T-CTS2214有2例，T-L162有1例，另有1例E-M123。线粒体单倍群较分散，J2a2d和T2e各3例，R0a和K1a-C150T各2例，T1和I6各1例。父系T系占绝对优势，母系来源多样，符合混合人群特征。

对祖源爱好者的意义

对祖源爱好者来说，这项研究说明现代中东人群的遗传多样性早在铜器时代就已由多波迁徙混合奠定。父系T系和多样母系组合，提示当时社会可能以本地父系为基础，持续吸纳外来女性或群体。

摘要

The material culture of the Late Chalcolithic period in the southern Levant (4500–3900/3800 BCE) is qualitatively distinct from previous and subsequent periods. Here, to test the hypothesis that the advent and decline of this culture was influenced by movements of people, we generated genome-wide ancient DNA from 22 individuals from Peqi’in Cave, Israel. These individuals were part of a homogeneous population that can be modeled as deriving ~57% of its ancestry from groups related to those of the local Levant Neolithic, ~17% from groups related to those of the Iran Chalcolithic, and ~26% from groups related to those of the Anatolian Neolithic. The Peqi’in population also appears to have contributed differently to later Bronze Age groups, one of which we show cannot plausibly have descended from the same population as that of Peqi’in Cave. These results provide an example of how population movements propelled cultural changes in the deep past.
