Dietary correlates of gene evolution. Phylogenetic logistic regression analyses show (a) no correlation between amount of fruit/nectar in the diet and gene retention, but a (b) significant correlation between herbivorous diet and ADH7 loss. RELAX analyses suggest selective pressure (c) is relaxed in the absence of fruit/nectar in the diet and (d) intensifies in frugivorous/nectarivorous species.
