Scientists use teeth to understand relationships between individuals, populations and species in the past. Our research team is working to better refine our understanding of the genetic and non-genetic factors that determine the appearance, size and shape of teeth in the human mouth. This information will better define our understanding of recent human evolution and also has potential clinical applications for orthodontics as well as forensic applications for identifying the remains of unknown victims of crime.
This project uses documented dental cast collections to examine quantitative genetic variation of the human dentition. The goal is to provide foundational understanding of the determinants of human dental variation at the inter-individual, inter-populational and inter-species levels. A key component of the project is estimating pleiotropic effects among different dental crown dimensions and anatomical variants with respect to evolutionary developmental models of tooth crown formation. The project also provides novel estimates of narrow-sense heritability across a number of human populations.
