  1. BM values represent the mean +/− standard deviation of SURFACE parameter estimates across the 500 BM simulations of the morphological data. k = number of peaks before convergence; k’ = number of non-convergent peaks; c = number of shifts to convergent peaks; k’conv = number of convergent peaks; Δk = reduction in the number of peaks with convergence; c/k = the proportion of convergent peaks relative to the total number of peaks. P = the proportion of BM simulations that produced SURFACE parameters as high or higher than the preferred SURFACE model for PC1.
