Morphological Evolution of Mammalian Milk Teeth
Mammalian teeth tell us a great deal about the evolutionary histories and relationships of mammals. Most of what we know about teeth, however, pertains to adult teeth. In contrast, a lot of basic information about milk teeth (such as what they look like!) is either lacking or scattered in the literature. My colleagues and I have been systematically documenting and measuring milk-tooth forms in extinct and living carnivorans (dogs, cats, and their relatives) and primates to build a database and analyze their evolutionary patterns in comparison to those of the adult teeth. We are aiming to answer questions like:
(1) What drives the evolution of milk-tooth forms?
(2) To what degree do milk teeth and their adult counterparts evolve independently?
(3) Do milk-tooth forms preserve information about evolutionary relationships of animals that is not available from adult teeth?
We have been collecting data at various institutions with osteological collections, including EHUB/KUPRI.
