Quizplus · Accepted Answer

The dispersal of fruit flies (Drosophila) on the Hawaiian islands has resulted in adaptive radiation, which is the process by which a single ancestral species rapidly diversifies into many new species to fill different ecological niches. This diversification is typically driven by natural selection and leads to the evolution of unique adaptations in each new species. Therefore, the best term to describe the dispersal of fruit flies on the Hawaiian islands is adaptive radiation.
