Abstract

The Yi people in southwestern China are renowned for their unique history, social structure, and customs. However, due to extensive genetic admixture during their formative period, the early origin and evolutionary trajectory of the Yi people remain unclear. In this study, we identified four paternal founder lineages of Yi people and generated a highly revised phylogenetic tree for these four lineages with sixty-six sequences. Furthermore, the geographic distribution of four lineages within China was summarized, based on 465 individuals identified among 60,009 Chinese males. The divergence topology indicated that among all Tibeto-Burman-speaking populations, the Naxi, Bai, and Burmese populations exhibit the closest genetic affinity with the Yi people. The distribution of four founder lineages shows similar higher frequency in the Yunnan-Guizhou Plateau, the center of the Yi people’s inhabited area. We conducted an in-depth analysis of the possible origin, migration patterns, and the roles of these four components in the demographic history of Yi people.
