Genetic ancestry modeling for potential sources across newly reported genetic groups. a Evolutionary history with five admixture events constructed by qpGraph. The selected qpGraph-based phylogenetic topology fitted the best-worst Z scores below 3 (Z = − 2.674). Percentages on the dashed lines represent the admixture proportions of the two ancestral groups. Numbers on solid lines show 1000 times genetic drift. Admixture graph fitting GPH as an admixture of ancestries associated with Li_Qiongzhong and Upper_YR_LN. b Working distal qpAdm models with distinct ancestral sources. GPH show high levels of YRB ancestry. The error bar indicates the stand errors of predicted proportions of ancestors obtained from qpAdm. c The admixture proportions of proximal qpAdm models for GPH. Each bar represents ancestry proportions of the listed subgroups for GPH. ANEA, ancient Northern East Asian; ASEA, ancient Southern East Asian; NEA, Northern East Asian; SEA, Southern East Asian
