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.
