Researchers transplanted guppies from pools containing pikeÂcichlid fish (intense guppy predators) to pools containingkillifish (less active predators that prey mainly on juvenile guppies). They then determined whether color patterns in thetransplanted population changed over time. Researchers hypothesized that predation should result in selection for more drab colors in guppies because guppieswith bright colors are more conspicuous to predators.
