Fig. 3: Patterns of encephalization among carnivoran taxonomic groups.
From: The impact of environmental factors on the evolution of brain size in carnivorans

Calculated Phylogenetic relative brain size estimated for a families and b the two suborders. Grey dotted lines indicate the expected relative brain size under an allometric model (i.e., brain size is entirely explained by body mass and explained the entire variation observed for the dependent variable). Boxes represent the third and first quartiles and bold line represents the median.
