Figure 2 in Morphometric, Behavioral, and Genomic Evidence for a New Orangutan Species

Figure 2. Distribution, Genomic Diversity, and Population Structure of the Genus Pongo (A) Sampling areas across the current distribution of orangutans. The contour indicates the extent of the exposed Sunda Shelf during the Last Glacial Maximum. The black rectangle delimits the area shown in Figure 1A. n indicates the number of sequenced individuals. See also Table S4. (B) PCA of genomic diversity in Pongo. Axis labels show the percentages of the total variance explained by the first two principal components. Colored bars in the insert represent the distribution of nucleotide diversity in genome-wide 1-Mb windows across sampling areas. (C) Bayesian clustering analysis of population structure using the program ADMIXTURE. Each vertical bar depicts an individual, with colors representing the inferred ancestry proportions with different assumed numbers of genetic clusters (K, horizontal sections).
