Mammals show a high degree of diversity in skull and tooth morphology. Yet, while the bones of the skull can respond plastically throughout ontogeny, the cusps of teeth do not. Here I will present 1) how changes in muscle function affect both the external morphology and the internal bone microstructure of the craniofacial skeleton in different mouse models; and 2) what we can learn from hairless dogs about the genetic mechanisms underlying specific dental character-state transitions observed within and across mammalian lineages.
