Fig. 2From: Diet evolution of carnivorous and herbivorous mammals in LaurasiatheriaDigestive system pathways and positively selected genes found in ruminants (green) and cetaceans (red). Three digestive system pathways (A, B, and C) were modified from that of KEGG, including carbohydrate digestion and absorption (map04973), protein digestion and absorption (map04974), and fat digestion and absorption (map04975). Positively selected genes are shown in parentheses, and their corresponding proteins are highlighted in red (cetaceans) and green (ruminants)Back to article page
