Allometries for log₁₀ brain size versus log₁₀ body size across different taxonomic levels within Euarchontoglires based on bootstrap estimates of PGLS regression parameters. n = number of sampled species; λ = Pagel’s lambda (tree transformation that measures phylogenetic signal); SD = standard deviation.
