Divergence time estimates (posterior mean) and their 95% confidence intervals (CIs) in Ma (million years from present) for eleven nodes indicated in Figure 4. See Table S2 for details of the time constraints. Different minimum constraints of node #11 resulted in different divergence time estimates.
