Control region domain I clock rate calibrations and TMRCA estimates.

Control region domain I clock rate calibrations (substitutions/site/lineage/MY) and mean TMRCA estimates (MY) with 95% HPD intervals in brackets below. Rates estimated under a constant population size coalescent (Constant), expansion model (Expansion) and random local clock model (Local Clock) were constrained using the age of the root node calculated for ND3. Rates were also estimated by constraining the ages of gilgandra and superciliosus to the ND3 dates obtained for these nodes (Internal) and employing a constant population size coalescent.Control region domain I clock rate calibrations and TMRCA estimates.
