The best fitting model combination was highlighted in boldface. The molecular clock models used were the strict molecular clock (SC) and the uncorrelated log-normal distributed (UCLD) relaxed molecular clock. Coalescent models used were the parametric Constant model (Const), Exponential model (Exp), Logistic model (Log) and Bayesian skyline plot model (BSP). 95% HPD 95% highest posterior density, t MRCA the most recent common ancestor, AICM the Akaike information content model selection method
