分化与融合:晋西南先秦人群颅骨形态的亲缘关系矩阵模型分析

Differentiation and Assimilation:The R-Matrix Model Analysis of Skull Morphology in Pre-Qin Communities in Southwestern Shanxi

本文利用亲缘关系矩阵模型对852例先秦时期颅骨数据进行分析,将晋西南地区人群遗传结构演化划分为三个阶段:西周时期,该地区存在数支不同人群,其中包括来自北方狄人与中原商人的遗传成分;春秋时期,区域人群交融与文化整合同步,狄人遗传成分流入增加;战国时期,该地区居民主要延续了本土遗传成分,但在部分遗址也显示出强烈的关中秦人影响,可能与该时期秦人的东扩有关。亲缘关系矩阵模型揭示了晋西南先秦人群演化与历史进程的关联,提供了先秦人群融合的体质人类学证据。

This article employs the R-matrix model to analyze 852 crania samples from southwestern Shanxi during the Pre-Qin period.The analysis reveals three distinct stages in their genetic structure and evolution.In the Western Zhou Dynasty,the region was inhabited by multiple population communities,including genetic contributions from the Northern Di community and the Shang community.During the Spring and Autumn Period,cultural integration was evident,with a dominant genetic influence from the Di community.By the Warring States period,significant genetic flow from the Qin state impacted the local population,likely due to Qin state’s expansion.The R-matrix model highlights the correlation between population transitions and historical developments in southwestern Shanxi during the Pre-Qin period.
