Gyroscope Control for Moths

Gyroscope control for moths reported in Science, vol. 315, p863, 9 February 2007. Sanjay Sane of the University of Seattle has been researching how moths maintain stability in flight when they are so light that any gentle breeze could blow them off course. He analysed high speed films of moths in flight and measured the movements of their antennae. He also recorded the activity of a tiny sense organ at the base of each antenna. Putting this altogether he concluded that the moths use their antennae to measure the twists and turns of their bodies as they fly, in the same way that aeronautical engineers use movements of gyroscopes to stabilise aircraft and missiles in flight. To test his theory he cut off the antennae of some moths and filmed them flying. They were hopelessly unstable and flew in all directions, including upside down and backwards. When he glued the antennae back on the moths could fly normally.

Editorial Comment: Gyroscopes are precision instruments, and building them and installing them in aircraft takes creative design and engineering. No-one would try flying a plane with half made gyroscopes, and it is just as silly to imagine gyroscopes in insects evolving slowly and gradually over millions of years. We wonder how many half evolved moths spent their lives flying upside down and backwards but still managed to find a mate and pass on their half-evolved genes for evolution to work on. It is far more sensible to believe that moths were created as fully formed creatures, complete with needed antennae gyroscopes, ready to fly and multiple after their kind, as described in Genesis.
