Phylogeny of mammals and diversity of their craniofacial morphology. A, phylogeny of living mammals adapted from Tarver et al. [11], with phylogeny of Laurasiatheria based on Chen et al. [101]. B–M′, frontal and lateral views of mammalian heads: B and B′, platypus (Ornithorhynchus anatinus); C and C′, echidna (Tachyglossus aculeatus); D and D′, red kangaroo (Macropus rufus); E and E′, koala (Phascolarctos cinereus); F and F′, giant anteater (Myrmecophaga tridactyla); G and G′, Linnaeus’s two-toed sloth (Choloepus didactylus); H and H′, aardvark (Orycteropus afer); I and I′, rock hyrax (Procavia capensis); J and J′, domestic dog (Borzoi) (Canis lupus familiaris); K and K′, leopard (Panthera pardus); L and L′, common tree shrew (Tupaia glis); M and M′, common chimpanzee (Pan troglodytes)
