  2. Traits are measured as differences in values between sister-pairs of mammalian clades. Co-efficient: estimated co-efficient of the predictor variable; R2 = co-efficient of determination; d.f: degrees of freedom in model. Synonymous substitution rates and dN/dS ratios (ω) estimated in PAML indicated with #; all other rates were estimated in HyPhy. P value: significance of value of model; Significance: * = P < 0.05, ** = P < 0.005.
