Figure 2

Ultrametric tree showing phylogenetic relationships and divergence ages among macaques as calculated from complete mtDNA genome sequences (relationships among non-macaque taxa not shown). Red dots indicate ML bootstrap support of > 95% and Bayesian posterior probabilities of 1.0; values below are given at respective nodes. Blue bars indicate 95% CIs of divergence times and the time scale below shows million years before present. IDs correspond to those in Figure 1 and Additional file 2: Table S2. For detailed information about divergence ages and 95% CIs see Additional file 1: Table S1.
