Phylogenetic Principal Component Analysis of Pteropodidaes’ brain structure proportions. Regression on independent contrasts of logged absolute brain size onto independent contrasts of position on PC1: Multiple R-squared: 0.485, F-statistic: 36.73 on 1 and 39 DF, P = 4.272 × 10−7; PC2: Multiple R-squared: 0.0036, F-statistic: 0.1427 on 1 and 39 DF, P = 0.7077.
