Due to the lack of predators or rivals for the finches, Daphne Major makes an excellent location for research. They found that the, finchs beak size was correlated with the size of the seed they ate, (large beaked finches ate large seeds, and small beaked finches ate. They were able to measure the beak depth of the 1,200 finches that live on the island. Peter and Rosemary Grant and their colleagues have studied Galpagos finch populations every year since 1976 and have provided important demonstrations of the operation of natural selection. So it's not just a change in behavior, but a change that becomes inherited, so it is passed through the genes of the bird to the next generation. So, if a finch lives between 10 - 15 years, then during that time their feeding habits might change because of a change to habitat or their flight paths might change because of something that has been built that obstructs their path. The two are best known for their work studying darwin s. In the early 1960s medium ground finches were found to have a larger or smaller beak.
