背景中国东北的西辽河流域是一个生态多样化的地区，史前人类聚居，具有广泛的文化和生存方式。为了帮助了解该地区的人类进化史，我们对来自考古遗址的古人类遗骸进行了Y染色体分析，年龄从6500到2700 BP。结果70个个体中的47个提供了可重复性的结果。利用诊断性单核苷酸多态性将其分为5个不同的Y亚群，即N1(xN1a，N1C)、N1C、C/C3E、O3a(O3a3)和O3a3c。我们还在Y染色体的非重组部分使用了17个Y短串联重复序列。史前时期西辽河流域与邻近文化综合体的人群之间存在着显著的遗传差异，这些史前人群携带着与今天东北亚人相似的单倍型，但频率明显不同。结论我们的结果表明，史前文化变迁与黄河流域和北部草原移民到西辽河流域有关。它们揭示了西辽河流域人口Y染色体谱系在5000多年来的时间连续性，同时其他人口移民的涌入导致了谱系多样性的增加。
BackgroundThe West Liao River valley in Northeast China is an ecologically diverse region, populated in prehistory by human populations with a wide range of cultures and modes of subsistence. To help understand the human evolutionary history of this region, we performed Y chromosome analyses on ancient human remains from archaeological sites ranging in age from 6500 to 2700 BP.Results47 of the 70 individuals provided reproducible results. They were assigned into five different Y sub-haplogroups using diagnostic single nucleotide polymorphisms, namely N1 (xN1a, N1c), N1c, C/C3e, O3a (O3a3) and O3a3c. We also used 17 Y short tandem repeat loci in the non-recombining portion of the Y chromosome. There appears to be significant genetic differences between populations of the West Liao River valley and adjacent cultural complexes in the prehistoric period, and these prehistoric populations were shown to carry similar haplotypes as present-day Northeast Asians, but at markedly different frequencies.ConclusionOur results suggest that the prehistoric cultural transitions were associated with immigration from the Yellow River valley and the northern steppe into the West Liao River valley. They reveal the temporal continuity of Y chromosome lineages in populations of the West Liao River valley over 5000 years, with a concurrent increase in lineage diversity caused by an influx of immigrants from other populations.
