Accuracy of the rooting method when the molecular clock assumpon is violated. In each panel, the x-axis denotes the data size (number of coalescent independent sites in kb), and the y-axis shows the proportion of the data sets for which the correct rooting position is selected in a total of 500 simulations. a Asymmetric species tree with root position ① for which the branch leading to taxon A has been extended; b Asymmetric species tree with root position ① for which the branch leading to taxon C has been extended; c Symmetric species with root position ⑤ for which the branch leading to taxon A has been extended; d Proportion of times root position ⑤ is selected for the star phylogeny. All simulations used the JC69 model, since the first simulation study did not indicate systematic differences in performance based on varying the model
