傣族是o2-m117 和o1b1a1-pk4主导的

那么彝族的o2成分应该来自傣族了

O2a2b1a1a6b1a-SK1730 通过yfull 算出来是 2400年 ，O2a2b1a1a4a-CTS5492通过yfull算出来是2500年，这两个似乎都不占彝族O2的主流，而O2a2b1a1a6b-Z25928老一些不过在傣族中比例远逊于第一个支系，而且看了兰海论坛公布的树型和彝族并非是傣族支为上游彝族支为下游的关系而是类似兄弟支系的关系。

傣族是东亚成分，东亚成分核心区是江苏 山东 福建 韩国 本州岛

傣族成分与壮族成分差异大，不过都是东亚，傣族融入一定的壮族成分，部分傣族南下泰国融合泰国人成分成为泰族，泰国人成分是中南半岛成分，与越南京，柬埔寨都是中南半岛成分的子集

@嘉绒wa 看来你没有因为自己测出M117就歪屁股，你对骑士魁首说的关于尼泊尔古人的情况没错

Interestingly, all reads from our ACA individuals match the derivedallele for the nonsynonymous EGLN1 SNP rs186996510 (SIAppendix, Table S2), including the oldest Chokhopani sample (C1).This derived allele, c.12G > C (p.Asp4Glu), is reported in high frequencyin Tibetans (0.64–0.85) (22, 37), but is rare in low-altitudeEast Asians (0.03 in 1KG phase 3 East Asians) and virtually absentoutside East Asia. Functional studies have implicated this allele asplaying a role in oxygen homeostasis under hypoxic conditions (37,39). In contrast, reads supporting derived alleles at the EPAS1 SNPswere found in two of the three later Samdzong individuals (S35 andS41), but not in the earlier Chokhopani (C1) or Mebrak (M63) individuals.This observation of shared adaptive alleles between ancientACA individuals and contemporary Tibetans is consistent with ourgenome sequence results suggesting that the ACA inhabitants areaffiliated with contemporary high-altitude East Asians. In addition,the contrasting pattern of alleles for the two genes leads us to speculatethat the EGLN1 and EPAS1 adaptive haplotypes rose to highfrequency at different time points in these ancient high-altitudepopulations, although more samples must be sequenced to accuratelyestimate allele frequency change across time.
