The University of Florida Explore Magazine produced an article on the Fraser Lab shark tooth research!

Re-evaluating the morphological evidence for the re-evolution of lost mandibular teeth in frogs. Evolution. 2021 Dec; 75(12):3203-3213. doi: 10.1111/evo.14379. pdf  Dan has been awarded a National Science Foundation (NSF) Postdoctoral Research Fellowship in Biology, in a joint project between the labs of Jim Hanken and Scott Edwards at Harvard, and the Fraser lab, at the University of Florida. The title of Dan's project is: Uncovering the Mechanisms of Convergent Tooth Loss in Frogs: Linking Developmental Genetics, Comparative Genomics, and Environmental Effects.
This work will allow Dan to understand the EvoDevo mechanisms of tooth loss and gain in frogs. This collaborative grant with George Lauder at Harvard and Elizabeth Sibert at Yale, will investigate how shark denticles change through deep time and development, and how their evolution can lead to innovative design solutions. Deep Time, Development, and Design: Evolution of shark skin teeth from genotype to phenotype to prototype. Here is the University of Florida, College of Liberal Arts and Sciences News Article.  |
