Despite some contrary evidence, the narrative that larger males are the norm in mammals—upheld since Darwin’s Descent of Man —still dominates today, supported by meta-analyses that use coarse measures of dimorphism and taxonomically-biased sampling. With newly-available datasets and primary sources reporting sex-segregated means and variances in adult body mass, we estimate statistically-determined rates of sexual size dimorp
