Figure 3. Ultrametric subtrees showing phylogenetic relationships and divergence times within Chlorocebus (above) and Papio (below) as obtained from the BEAST reconstruction using the GTR + I + G substitution model, a Yule tree prior and Calibration Set 1 (the complete tree is shown in Fig. S1). Newly generated Chlorocebus mtDNA genome sequences are marked with an asterisk (see Table S1). C1–C9 indicate the nine major mtDNA clades within Chlorocebus according to Haus et al. (2013b); x = putative hybrid due to intermediate phenotype. A–G indicate the seven major mtDNA clades within Papio (Zinner et al., 2009, 2013). All nodes are numbered (Chlorocebus: t6–t18; Papio: t26–t34). BS and PP values lower than 100% and 1.0 are given at respective nodes. Blue bars represent 95% confidence intervals of divergence times. The timescale is calibrated in million years. The estimated divergence times are given in Table S2. Primate illustrations by Stephen Nash.
