A time-measured phylogenetic tree of M. smithii reconstructed on the basis of the core genome using a Bayesian approach under a strict clock model. Purple and orange violin plots illustrate the 95% HPD values (in parentheses) of estimated mean ages for the diversification of M. smithii and the split of the lineage leading to ancient M. smithii (highlighted in red), respectively.
