Dolphin ancestor’s hearing was more like hoofed mammals than today’s sea creatures
Evolution@Vanderbilt paleontologists Rachel A. Racicot, visiting scholar, and Simon A.F. Darroch, Assistant Professor of Earth and Environmental Sciences, and their collaborators are looking into the evolutionary origins of the whistles and squeaks that dolphins and porpoises make – part of the rare echolocation ability that allows them to effectively navigate their dark environment. The study appeared in the journal Biology Letters.
