Two species of three-spined stickleback fish have been found together in five different lakes. The larger, bottom-dwelling species feeds on large prey close to shore. A surface-dwelling species feeds on small plankton in open water.

Which prezygotic mechanism most likely allowed divergence of an ancestral species into these present-day species
