The Trinidadian guppy is a model for evolutionary studies in natural settings, where this tiny fish is able to evolve its color, behavior, and breeding patterns in response to different predator regimes. Along with several others in biology’s guppy group, Cameron Ghalambor and Kim Hoke have extended the experiments demonstrating evolution in wild populations of guppies to genomic analyses of which genes are turned on and off during the evolutionary process.

Their study was published in Nature, one of the most prestigious peer-reviewed journals in science. For more, including videos featuring Cameron and predation on guppies, see the article on Colorado State’s SOURCE :
