FIGURE 17. Timetree of arboranan frogs estimated with RelTime from DNA sequence data of 19 genes (16,128 aligned sites), based on the ML topology (Fig. 4). Estimated dates of divergence are indicated at each node (in millions of years), with blue bars representing 95% confidence intervals. Calibrated nodes are marked with red dots. The tree is rooted with Ceuthomantis smaragdinus, Dendrobates auratus, Haddadus binotatus, and Rhinoderma darwinii (not shown).
