Evolution of the sweet (A) and umami (B) taste receptors in Carnivora in relation to feeding habits and modes. The events of loss of these receptors (A to T) are inferred from phylogenetic placement of TAS1R inactivating mutations (Tables 1 and 2). Not shown are species with no or incomplete DNA data that prevented conclusion about sweet/umami receptor absence/presence (for all species, see Supplementary Fig. S1). Phylogenies are compiled from Koepfli et al. (2008), Sato et al. (2012), Wolsan and Sato (2020), Pagès et al. (2008), Lindblad-Toh et al. (2005), Johnson et al. (2006), and Eizirik et al. (2010).
