| Sumario: | 8 pages. -- Table S1: passport information for all the samples analyzed in the study, including accession number and sample name from the reference publication. The field “group” is assigned based on the DAPC analyses. -- Table S2: Patterson’s D (ABBA-BABA), all tested triplets. Significant results are shown in bold. As per D-suite, the populations are always ordered to infer gene flow between P2 and P3 (D>0 ). -- Fig S1: Principal Component Analysis of the modern (whole genome) dataset, prior to group determination: two outliers are identified and excluded from further analysis, while major groups are identified. -- Fig S2: xValDAPC showing the best number of PCs to retain for DAPC analysis, based on the highest proportion of successful outcome prediction (0-1). -- Fig S3: Neighbor Joining analysis with 100 bootstrap replicates of the modern (whole genome) dataset. Bootstrap values are not shown (all nodes have bootstrap more than 90). -- Fig S4: Admixture plots from K=2 to K=6, modern whole genome dataset. -- Fig S5 (a-d): TreeMix residuals.
