Figure 2

Phylogenetic relationships of anurans, estimated divergence ages, and major mitochondrial genomic rearrangements in ranoid lineages. The maximum likelihood (ML) tree of the anurans from the complete mitochondrial (mt) genome and nine nuclear genes (the Nuc–dataset) is shown. Numbers on the nodes indicate ML bootstrap values / Bayesian posterior probabilities for, respectively, the Nuc-dataset and an AA-dataset, in which the coding genes were transcribed. The estimated ages and 95% confidential intervals of 16 nodes (I–XVI) are shown in the upper left box. Circled numbers (1–6) and blue branches on the tree indicate lineages with major mitogenomic rearrangements. Details of the rearrangements in each lineage are shown in the box at lower right.
