Lake Ontario is home to a species of catfish with green and brown phenotypes, of which the green variant is more abundant, and the brown variant is more susceptible to predation. An angler accidentally releases brown catfish into a nearby pond where only green catfish had previously existed, and the brown catfish quickly supplant the native green catfish population there. The exact reason for the brown catfish’s newfound success is unknown, but it is possible that they are better able to hide from predators in the brown silt and thicker foliage that exists in the pond. What principle would this demonstrate?
a. directional selection b. absolute fitness c. relative fitness d. diversifying selection
