Fig. 3

Empathy scores, per species, between children and the two comparison groups: (A) children vs. adults from the general population and (B) children vs. adults with ASD. The outlines of the different polygons represent the four main clades nested within each other, whereas their coloured surfaces (excluding the clades they contain) are representing different non-overlapping grades (i.e., subsets of species defined according to the degree of phylogenetic divergence from humans). The position of the human species is depicted as a large black dot.
