Two UChicago Bioscience alumni and faculty member discover that ancient sharks are much more like modern sharks than predicted

Alumni Aaron Olsen (PhD, Integrative Biology, 2016, now at Brown University) and John Finarelli (PhD, Evolutionary Biology, 2007, now at the University College Dublin, Ireland) worked with Professor Michael Coates, Department of Organismal Biology on a study about ancient shark feeding methods. Coates, senior author of the study, remarked, "Among today's aquatic vertebrates, suction feeding is widespread, and is often cited as a key factor contributing to the spectacular evolutionary success of ray-finned fishes. But here we show that high-performance aquatic suction feeding first appeared in one of the earliest known sharks."
