Fig. 31 in The Amphibian Tree Of Life

Fig. 31. Maximum­likelihood tree of various ranoids constructed by Van der Meijden et al. (2004) on the basis of 1,566 bp of the nuclear gene RAG­1. Sequence alignment was not reported. Cost functions of analysis were not provided nor which model of nucleotide evolution (as suggested by ModelTest; Posada and Crandall, 1998) was employed in the analysis. The tree was rooted on Xenopus laevis. We inserted the higher taxonomy on the right to allow easier comparison to other studies discussed in this section.
