I am happy to report that our new study came out this week in Ecology and Evolution! The paper is open-access and freely available.
This new research investigates the diversity of tooth morphology in mammals, finding that, contrary to previous assumptions, diet does not play a dominant role in the evolution of dental proportions. Instead, the study points to stabilizing selection as a key factor in understanding the diversity of tooth morphology in mammals. The study, a collaboration between scientists in the United States and France, looked at the teeth of more than 1,500 mammals held in museum collections in six countries to investigate the role of ancestry and diet on the evolution of dental proportions. This is the largest investigation of dental proportions to date.
