The diagram represents the relationship between beak structure and food in several species of finches found on the Galapagos Islands. The different beak structures observed in the diagram are evidence of

• different species of finches adapting to different environments over many generations

• finches changing their beak characteristics so that they could feed efficiently

• finch species with different beak structures coming to the Galapagos Islands from the mainland

• finches mating with birds of other species and acquiring some of their traits
