Table 3 Within-clade (numbers in italics) and between-clade (numbers in regular font) divergence time estimates obtained using a coalescent-Bayesian framework as implemented in BEAST v1.4.6 applied to the mitochondrial control region and 16S sequences (not available for B. variabilis). The African-Sicilian divergence time estimates (boulengeri to siculus) are printed in bold. Estimates are shown in My. Values in parentheses show the 95% highest posterior density intervals (95% HPD); they represent the shortest intervals that contain 95% of the posterior sampled values.
