are nearly unique. Instead of having many teeth that are frequently replaced, mammals have one set of baby teeth and later one set of adult teeth that fit together precisely. This is thought to aid in the grinding of food to make it quicker to digest. Endothermic animals require more calories than
710:, probably had whiskers. A common ancestor of all therian mammals did so. Indeed, some humans even still develop vestigial vibrissal muscles in the upper lip. Thus, it is possible that the development of the whisker sensory system played an important role in mammalian development, more generally. 3115:

They, however, prevent the expansion of the abdomen, and so force species that possess them to either give birth to larval young (as in modern 620:, so speeding up the pace of digestion is a necessity. The drawback to the fixed dentition is that worn teeth cannot be replaced, as was possible for the reptiliomorph ancestors of mammaliaforms. To compensate, mammals developed 548:. In contrast, the assignment of organisms to Mammalia has traditionally been founded on traits and, on this basis, Mammalia is slightly more inclusive than Mammaliaformes. In particular, trait-based taxonomy generally includes 634:, along with other characteristically mammalian features, is also thought to characterize the Mammaliaformes, but these traits are difficult to study in the fossil record.
