A species of lizards migrates to a group of islands in the ocean. Over time, they diversified and evolved into several different species. Each species has a unique jaw shape that allows it to eat its own specific diet. This is an example of

gradualism because one species evolved into several different species over a relatively short amount of time
adaptive radiation because one species evolved into several different forms that occupy different niches
coevolution because the evolving lizard species changed in order to interact with the changing environment
convergent evolution because one species evolved into multiple species that live alongside each other
