We offer brief commentaries on Boivin and Marivaux´s account of caviomorph molar morphology and evolution. In accordance with Van Valen´s statement ´Homology is resemblance caused by a continuity of information´, we reaffirm that understanding the dental morphology of rodents should be focused on identifying, i.e. keeping in sight, a given structure undergoing multiple transformation processes in ontogeny and phylogeny. Many of these evolutionary pathways may be tracked with reasonable confidence and can provide keys to recognize widespread patterns.
