Figure 3From: The origin of modern frogs (Neobatrachia) was accompanied by acceleration in mitochondrial and nuclear substitution ratesML phylograms derived from separate (a) mt and (b) nuclear nucleotide data sets. Neobatrachian lineages are abbreviated as Ca, Calyptocephalellidae, He, Heleophrynidae; Li, Limnodynastidae; Nob, Nobleobatrachia; Mh, Microhyloidea; and Nt, Natatanura. Note that the most conspicuous differences between both trees are (i) the relative phylogenetic position of Sooglossoidea, (ii) the scale bar (substitutions/ site), which is proportionally 10 times larger in (a) than in (b), and (iii) that neobatrachian branches are distinctively longer in (a) than in (b).Back to article page
