Soares and her colleagues used high-speed cameras to film a group of nine male guppies from the island of Trinidad. Their research, published online April 16 in the journal PLOS ONE, suggests wild guppies use their curious jumping ability as a way to spread the species away from an original habitat, to a new place with fewer predators. In other words, jumping likely serves a crucial evolutionary function for guppies.
