General population structure inferred from principal component analysis and model-based ADMIXTURE. a Patterns of genetic relationship among 93 ethnolinguistically distinct modern East Asians and 58 ancient populations, in which ancient people were projected into the essential background of two top components extracted from modern genetic variations. Populations from different language families or archeologically different groups were color-coded with different colors and different shapes, presenting different populations within one language family or archeological group. b Individual or population ancestry components among 210 ancient and modern Eastern Eurasian groups were inferred based on the ADMIXTURE with seven predefined ancestral sources. The model with K = 7 possessed the lowest cross-validation error
