    As a young graduate student, I first met Ken Norris amidst the collection of marine mammal bones in the basement of the Smithsonian's Museum of Natural History. He revealed that he was visiting to test an off-beat idea about dolphin cranial structure that might explain some of their acoustic abilities. After a day or two, he concluded that he was off the mark but at least had pursued the possibility and could now reject the hypothesis. Later, in a book on spinnner dolphins, he eloquently described his approach to scientific inquiry. He strove to understand nature through observing and hypothesizing, and then testing and retesting. The approach works, he wrote “because nature is not reluctant to point out my mistakes, and because I have trained myself to discard fallen hypotheses. But one must reconcile oneself to creeping up on truth through a thicket of these fallen hypotheses.” Driven by this philosophy, Ken would appreciate the intent of this paper, to discard a previous hypothesis in favor of one that better reflects nature.
