Saturation plots and Bayesian results. a Saturation plots for Matrices A, B and C, illustrating that Matrix A has the lowest level of saturation. The dots represent the intersection between uncorrected genetic distances and the patristic distances obtained under ML for each pair of the 95 taxa. The lines of best fit show the general trend and direction of the data and above is shown the R² and the slope of the regression line. Matrix A is represented in green, Matrix B in magenta and Matrix C in blue. Source data are provided as a Source Data file. b Schematic representation of the results of the CAT-GTR + G analysis of Matrix A. c Schematic representation of the results of the CAT-GTR + G analysis of Matrix B. d Schematic representation of the results of the CAT-GTR + G analysis of Matrix A, after Dayhoff-6 recoding. b–d Lineages are summarized at the ordinal level. Support values represent posterior probabilities, with lack of a number indicating maximum support. Silhouettes designed by ART
