Shown are the Pearson correlations between observed and predicted spectra of adaptive substitutions, their 95% confidence intervals and P values, the number of nonzero elements in the spectrum of adaptive substitutions (out of 354), and the entropy of the spectrum of adaptive substitutions normalized so that uniformity corresponds to an entropy of 1.
