- Estimates of divergence times expressed in million years. CLOC: rates conformed to a molecular clock. UCLN: rates uncorrelated, with the rate in each branch independently drawn from a lognormal distribution. HPD: highest posterior densities. The geological epochs corresponding to divergence times followed the 1999 Geologic Time Scale of the Geological Society of America. Oli.: Oligocene; Mio.: Miocene.
