"An Australian biologist has come up with a theory that the Cambrian explosion was a rapidly-escalating arms race catalyzed by the development of the first creature with vision." As biologist Andrew Parker puts it, "A light switch was turned on. All animals (even those without eyes) needed to be adapted to vision before they were eaten, or before they were outwitted by their prey." (Via Transterrestrial Musings.)
