Fruit flies display geotaxis, or a response to the earth's gravity. If the flies are within a vial and the vial is flipped upside down, the flies will crawl to the top of the vial. A researcher notices that a group of flies that had been exposed to radiation no longer exhibit geotaxis. How could you provide further evidence that this behavior is innate and not learned?
