  1. K values are mean weighted substitution rates for (1) non-neobatrachians, (2) all neobatrachians, (3), species-poor neobatrachians (Heleophrynidae, Calyptocephalellidae, Limnodynastidae, Sooglossoidea), and (4) species-rich neobatrachians (Ranoides and Nobleobatrachia). Probabilities (p) of relative-rate tests correspond to the comparisons between the different groups (shown in parentheses). Statistically significant results (p < 0.05; or p < 0.05/3 = 0.0167 to correct for multiple testing) are in bold italics and marked with an asterisk. Abbreviations of mt genes follow [44]; see main text for full names of nuclear genes.
