Figure 3From: Functional evolution of the trace amine associated receptors in mammals and the loss of TAAR1 in dogsPhylogeny of mammalian TAAR1. Branch length is proportional to nucleotide divergence. Lineage-specific dN/dS values are displayed. Note that the dN/dS value associated with the cat terminal branch extends to the last common ancestor between Carnivora and Cetartiodactyla.Back to article page
