Extended Data Fig. 2: Ancestry models inferred for 122 Phoenician-Punic individuals using unsupervised ADMIXTURE with K = 2, 3, 4 and 5 latent ancestry components.
From: Punic people were genetically diverse with almost no Levantine ancestors
The 122 Phoenician-Punic individuals sequenced for more than 100,000 SNPs were jointly analysed with 24 individuals from related ancient populations across the Mediterranean (Supplementary Table 12). (a) The model with the highest likelihood was obtained for each value of K among 50 replicate runs. Individuals are grouped based on region. Values of the ΔK score of58 are specified for K = 3,4, with a higher score obtained for K = 3, suggesting optimal fit. (b) A more detailed depiction of the best model obtained with K = 3 latent ancestry components corresponding to North African ancestry (red), eastern ancestry (green), and central/western Mediterranean ancestry (blue). Individuals are partitioned within each region according to site and time range (see legend). The unsupervised ADMIXTURE model does not adequately differentiate between Levantine ancestry and ancestry found in other Mediterranean locations (e.g., Anatolia and Sicily), unlike the qpAdm models of Extended Data Fig. 3.
