Laurel Symes, Neukom Post-doctoral Scholar in Biological Sciences, interviewed for the journal Nature about the application of multiple working hypotheses in science. The paper cites a recent publication by Laurel, inspired by our teaching philosophy in Dartmouth's Department of Biological Sciences: A Practical Guide for Mentoring Scientific Inquiry.

Gears in a jumping insect. Gears, for all the mechanical advantages that they can provide, have rarely appeared in the evolution of life on Earth. But never say never when it comes to insect evolution. Gears have just been found to be a crucial feature of the remarkable propulsive capabilities of a flightless planthopper.
