Rate of morphological evolution. Evolution of the morphological traits measured on the sample of 100 phylograms (A) and chronograms (B). Rates of clownfishes are in orange, damselfishes in blue and the one-rate model is shown in white. The P-values of model comparison by likelihood ratio test is signified by asterisk (* = P-values <0.05, ** = P-values <0.01). The schematic position of each morphological trait is shown on the clownfish drawing.
