From: The origin of modern frogs (Neobatrachia) was accompanied by acceleration in mitochondrial and nuclear substitution rates

Figure 1

Phylogenetic relationships of extant frogs. The ML phylogram inferred from the combined nucleotide data set is shown. The inferred tree based on the combined amino acid data set arrived at the same topology, which represents our best hypothesis for anuran phylogenetic relationships. Numbers at nodes are support values from ML (bootstrap proportions; left) and BI (posterior probabilities; right). Names of major clades of frogs are shown in capitals, Neobatrachia is highlighted in blue, and familial and supra-familial assignments are indicated for neobatrachians. Scale bar is substitutions/ site. The consensus gene order of the vertebrate mt genome is shown as well as variations of this gene order along the phylogeny. Genes encoded by the light strand are underlined. Different colors are used to indicate the origin of replication of the light strand (grey), translocated protein-coding genes (orange) and transfer RNA genes (blue). Abbreviations of mt genes follow [47].
