Figure 2.

Genes showing site-wise adaptive evolution supported by mutually exclusive amino acid substitution from eight monotocous and seven polytocous mammals. Monotocous mammals are represented with a gray background color and bold letters. Phylogenetic relationship is presented below the table and the branches that have undergone adaptive evolution as implied by a parsimonious approach (see method) are represented with a thick line. ω_f: estimated dN/dS, H0: null model, H1: alternative model, BEB: Bayes empirical Bayes.
