Examples of inactivating mutations in genes that are preferentially lost in herbivores (A and B) or carnivores (C–F). The coding exon–intron structure of each diet-related gene is shown at the top. For space considerations, Insets show only one representative inactivating mutation for only one gene-loss lineage, distinguishing herbivores by blue font and carnivores by red font. Black and gray boxes indicate nucleotides that belong to the same codon. All inactivating mutations in these genes are validated by raw DNA sequencing reads and are shown in SI Appendix, Figs. S3–S8.
