Models predicting genome size within 95% cumulative AIC weight after excluding models with uninformative parameters for the 289-species dataset (f, relative flight muscle size; h, heart index; m, body mass). PGLS, phylogenetic generalized linear model; regression, conventional (non-phylogenetically corrected) linear regression.
