Genome-wide RRTs of Banna caecilian, Western clawed frog and human using nucleotide sequences. RRTs were performed on the nucleotide sequences of 623 orthologous genes, with Banna caecilian, Western clawed frog and human as the ingroups and Indonesian coelacanth as the outgroup. The number in a cell represents the number of statistical significance (highly significant **, significant *) for RRTs of a species compared with the others; hence, there are six possibilities for each ingroup species. Increasing warm color intensity indicates faster relative evolutionary rate, whereas increasing cold color intensity indicates slower relative evolutionary rate
