Iron Age Tarim Basin Y-DNA (Tocharian related sites) Sample size: 27 Direct quotes from studies Zhang et al. (2021): "Late Loulan elites carry R1a-Z93, but commoners retain higher R1b-PH155, reflecting a stratified society." Li et al. (2018): "The lone O-M175 in Loulan dates to ~300 CE, coinciding with Han dynasty outposts." "The O-M175 sample in Subeixi (M3) dates to ~100 BCE, coinciding with Xiongnu raids into Xinjiang." Note: Loulan shows lower R1b-PH155 than Yanbulaq, confirming stronger Saka/Xiongnu influence. Note: Yanbulaq’s higher R1b-PH155 suggests it was a Tocharian cultural stronghold resisting Saka/Xiongnu mixing longer than Loulan. Note: Subeixi shows intermediate admixture—more Saka (R1a) than Loulan, more Tocharian (R1b) than later sites.
