Tables 1, 2 and 3  Regressions between rates, clade size and body size for mitochondrial sequence data Traits are measured as differences in values between sisterpairs of mammalian clades. Coefficient: estimated coefficient of the predictor variable; R^{2 }= coefficient 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.
