Hadfield, Adam Eyre-Walker A population’s ability to adapt is determined by its levels of additive genetic variance ( V A ), and while it is agreed that most organisms have genetic variation for most traits, the extent to which it varies between species is poorly characterized. Here, we investigate this question by compiling 3,209 and 1,852 estimates of heritability and evolvability (the additive genetic variance divided by the square of the mean), respectively, for a variety of traits from 220 and 172 multicellular eukaryotic species. Using phylogenetic generalized linear mixed models, we find substantial and highly significant interspecific variation in evolvability. Much of the variation is explained by phylogenetic relatedness, with plants in our data having substantially higher evolvability than animals. While heritability also varies between species, the differences are more subtle, and plants are not exceptional. We investigate wh
