Correlations, sample sizes and log-likelihoods for mean-centred residuals. (Correlation coefficients are given between encephalization and each variable's residuals, re-centred such that the group mean is zero (see the electronic supplementary material for discussion). Gestation time and number of litters per year were reconstructed with significantly different among-group correlations, and each correlation and its log-likelihood is given. All other variables were reconstructed with a single, homogeneous correlation across Carnivora. Correlations that were significantly different from zero (log L < −2) are highlighted in bold.)
