Objectives: Previous studies of archaeology and history suggested that the rise prosperity Bronze Age culture in East Asia had made essential contribution to formation early state civilization this region. However, impacts perspective genetics remain ambiguous. genetic researches indicated Y-chromosome Q1a1a-M120 N1a2a-F1101 may be two most important paternal lineages among people ancient northwest China. Here, we investigated 9,000-years haplogroup with revised phylogenetic tree spatial autocorrelation analysis. Materials Methods: In study, 229 sequences were analyzed. We developed a highly-revised age estimates for N1a2a-F1101. addition, also explored geographical distribution sub-lineages N1a2a-F1101, analysis was conducted each sub-branch. Results: The initial differentiation location its closely related branch, N1a2b-P43, major lineage Uralic-speaking populations northern Eurasia, is likely west part northeast After ~4 thousand years bottleneck effect period, haplgroup experienced continuous expansion during Chalcolithic (~ 4.5 kya 4 kya) 2.5 Ancient DNA evidence supported ruling family Zhou Dynasty 3 kya-2.2 Discussion: general, proposed border area between eastern Eurasian steppe China not only played key role promoting China, but left significant traces gene pool Chinese people.
