Fig. 2: Phylogeny of Podarcis wall lizards.
From: Extensive introgression and mosaic genomes of Mediterranean endemic lizards

a The time-calibrated ML phylogenetic tree of the 34 major lineages of wall lizards based on whole-genome sequences (outgroup not shown). All nodes were 100% supported with 1000 bootstrap replicates, but not across all local trees (grey-scale of nodes signifies proportion of local trees derived from 200 kb windows in support of a given node). The lower panel shows the geological time scale of the evolutionary history of Podarcis and the estimated diversification rate. The thick red line indicates the Messinian Salinity Crisis (~6.0–5.3 MYA). The coloured rectangles on the tips of the tree denote geographically coherent groups of wall lizards. b A summary of the similarities, given as normalized Robinson–Foulds distances, between all phylogenies reported in this study (phylogenies are shown in Supplementary Fig. 5 and Supplementary Figs. 8–10). See Supplementary Table 2 for a summary of approaches and datasets. c A ‘DensiTree’ illustration of the prevalent discordances among 500 randomly selected local trees derived from 200 kb windows (with branch length proportional to genetic change).
