An Evolutionary Interpretation of Several Ontogenetic Stages of the Tooth Development in Rabitt
Abstract:
The existence of two morphological gradients in the dentition of both contemporary and fossil lagomorphs was pointed out, using comparisons of different stages in the ontogenetic development of dental structures, such as hypostria and crescent. This last structure, which disappeared in lagomorphs in the Miocene, was successfully identified in the early developmental stages of the permanent premolars and molars of the rabbit. Resemblances were found in the order in which several dental structures arise and disappear in ontogeny and phylogeny.
