Students in AP Biology classes received a virtual visit from Kelsie Pos, a Ph.D. candidate in evolutionary biology at George Washington University. Ms. Pos’s research focuses primarily on fish and pharyngeal jaws; she is particularly interested in how anatomy changes based on diet, habitat, and evolutionary history.
In addition to sharing her work and discussing the evolutionary biology of jaws (from fish to humans!), she described the research methods she uses including dissection, CT scanning, scanning electron microscopy, x-ray video, and biomechanical modeling. Thank you, Ms. Pos, for an informative presentation.
