Table 2 Estimation of coalescence times. Bayesian analysis and parameter estimation using a non-correlated relaxed molecular clock and dating of major clades in the trees of Figures 2 and 3 assuming a Yule tree prior and alternative coalescent population growth models. Mean and 95% HPD values are indicated in millions of years.
