Duke University Along with our big brains and upright posture, thick tooth enamel is one of the features that distinguishes our genus, Homo, from our primate relatives and forebears. A new study, published May 5 in the Journal of Human Evolution, offers insight into how evolution shaped our teeth, one gene at a time.

Researchers at the University of Pittsburgh School of Dental Medicine are piecing together the process of tooth enamel biomineralization, which could lead to novel nanoscale approaches to developing biomaterials. The findings are reported online this week in the Proceedings of the National Academy of Sciences. Dental enamel is the most mineralized tissue in the body and combines high hardness with resilience, said Elia Beniash, Ph.D., associate professor of oral biology, Pitt School of Dental...
