A) Influence of each factor on New World monkey brain shape. B) Brain shape factors plotted along New World monkey phylogeny. The coefficients of the first three principal components (PCs) from Aristide et al. (2016) are highly correlated with the corresponding rows of the loadings matrix. While we do not explore such an analysis here, Aristide et al. (2016) provide evidence of association of PC1 (strongly correlated with our first factor) with relative brain size and PC2 (strongly correlated with our second factor) with diet.
