PCA of Present-Day Eurasian Populations and Genetic Structure of Mongolia through Time, Related to Figure 2

(A) PCA of present-day Eurasian populations used as the background for Figure 2 and Figure S3B. Here we show the population labels for the 2,077 Eurasian individuals used for calculating PCs and plotted as gray dots in Figure 2. Each three-letter code in the plot represents a single individual. Population IDs matching to the three-letter codes are listed at the bottom.

(B) Genetic structure of Mongolia through time. Principal component analysis (PCA) of ancient individuals (n = 214) from three major periods projected onto contemporary Eurasians (gray symbols). Projection and axis variance corresponds to Figure 2. Population labels are positioned over the mean coordinate across individuals belonging to each population.
