Fig. 4: Phylogeny of the 174 species of terrestrial carnivorans studied showing the repartition of their relative brain size and the estimation of its evolutionary rate and shifts at the ancestral nodes.
From: The impact of environmental factors on the evolution of brain size in carnivorans
Coloured dots represent the evolution rates of encephalization computed according to our phylogenetic Ridge Regression. Arrows represent the significant shifts of the evolution rate for the relative brain size. Taxonomic groups highlighted in red boxes display a significant increase in the rate of encephalization whereas the blue box indicate a significant decrease. The silhouettes were drawn by the authors (M.M) and are available on the Phylopic website http://www.phylopic.org/.
