The scientists who discovered Onychonycteris finneyi, the oldest known bat fossil, concluded that the prehistoric species could fly but that the sonar sense didn't evolve until later. But a recent study reinvigorated the echolocation-versus-flying timeline debate. Scientists know a lot about the finer points of how echolocation works, but they differ on whether that sense evolved before or after bat’s ability to fly.
