Phylogenetic relationships of the 12 mammalian lineages included in this study, and the alternative hypotheses for branch-site (LRT-1 and LRT-2) and clade analyses (LRT-3 and LRT-4). The red branches in hypotheses 1–3 are specified as the foreground branch in branch-site models A and B, which are employed to carry out LRT-1 and LRT-2 for episodic evolution. The red clades in hypotheses 4 and 5 are specified as the foreground clades in clade-site models C and D, which are employed to carry out LRT-3 and LRT-4 for long-term shifts in selection pressure.
