Extended Data Figure 3. Genetic affinities of the La Braña 1 genome.

a, Principal Component Analysis (PCA) of the La Braña 1 SNP data and the 1000G Project European individuals. b, PCA of La Braña 1 vs Omni world-wide data. Continental terms refer to each Omni population groupings as follows. Africans: Yoruba and Luyha. Asians: Chinese (Beijing, Denver, South, Dai), Japanese and Vietnamese. Europeans: Iberians, Tuscans, British, Finns and CEU; and Indian Gujarati from Texas. c, Each panel shows PC1 and PC2 based on the PCA of one of the ancient samples with the merged POPRES+FINHM sample, prior to Procrustes transformation. The ancient samples include the La Braña 1 sample, four Neolithic samples from Skoglund et al.³ and Keller et al.¹.
