From: Selection towards different adaptive optima drove the early diversification of locomotor phenotypes in the radiation of Neotropical geophagine cichlids

SURFACE parameters SURFACE BM P
K 2 3.18 +/− 1.14 0.95
k’ 2 2.70 +/− 0.88 0.95
C 0 0.92 +/− 0.17 1.00
k’ conv 0 0.43 +/− 0.55 1.00

  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.
