青铜时代南黎凡特古DNA揭示迦南人遗传来源与融合史。

科学家对南黎凡特青铜至铁器时代73个古人基因组测序,发现共享“迦南”文化的个体可建模为两源混合:本地新石器人群与扎格罗斯/高加索相关人群。非本地成分随时间增加,三个离群个体暗示近期移民。不同迦南群体彼此遗传更近。现代黎凡特人群普遍携带扎格罗斯和青铜时代南黎凡特相关血统,且存在无法完全建模的成分,说明近三千年迁移影响深远。

样本解读

站内样本共34例,Y染色体解析32例,以J单倍群为主,包括J-FGC8182、J-Z1865、J-P58等,另有E-Y6720。线粒体以H2a2a1、J1d1a1、K1a、T2c1a等为主。文化归属仅一例为Megido MB III-LB I。整体父系和母系多样性反映了青铜时代南黎凡特人群的复杂融合背景。

对祖源爱好者的意义

对祖源爱好者而言,这项研究提示现代黎凡特及部分地中海人群的遗传构成中,扎格罗斯和青铜时代南黎凡特相关成分占重要地位,且近三千年迁移持续塑造当地基因库,有助于理解J单倍群等父系谱系的古老融合历史。

摘要

We report genome-wide DNA data for 73 individuals from five archaeological sites across the Bronze and Iron Ages Southern Levant. These individuals, who share the “Canaanite” material culture, can be modeled as descending from two sources: (1) earlier local Neolithic populations and (2) populations related to the Chalcolithic Zagros or the Bronze Age Caucasus. The non-local contribution increased over time, as evinced by three outliers who can be modeled as descendants of recent migrants. We show evidence that different “Canaanite” groups genetically resemble each other more than other populations. We find that Levant-related modern populations typically have substantial ancestry coming from populations related to the Chalcolithic Zagros and the Bronze Age Southern Levant. These groups also harbor ancestry from sources we cannot fully model with the available data, highlighting the critical role of post-Bronze-Age migrations into the region over the past 3,000 years.
