Unformatted text preview: Adaptive Radiation as a Speciation Mechanism Patterns of speciation that involve adaptive radiation have been studied since Darwin's early work with the finch species on the Galapagos Islands. Darwin found fourteen species of similar birds on the islands, each feeding on separate food items, and each with a different beak shape. He speculated that the available food on the different islands "selected" for a specific beak shape. The distance between islands meant that only those birds in one area interbred, which resulted in the separation of species, and divergent evolution. Such multiple divergence is called adaptive radiation, and has been studied with many organisms....
