Extended Data Fig. 1: Comparison of genetic and geographic coordinates for European vs. Polynesian samples.
From: Paths and timings of the peopling of Polynesia inferred from genomic networks
a, A principal component analysis of samples from Europe (15 from each nation) is shown to closely fit the geography of Europe. (See Extended Data Fig. 2 for a quantitative comparison.) b, c, A principal component analysis (b) of samples from Polynesia (with non-Polynesian ancestry masked) is shown not to match the vast geography of the Pacific (c), and instead splits out island groups one at a time, reflecting the founder effects that dominate the variance of these populations.
