Course Hero is not sponsored or endorsed by any college or university. Since these slight variations are passed down from one generation to the next, the brood of a small beak and a medium beak would be likely to have intermediate beaks, equipment that would sometimes differ from their parents' not by one or two tenths of a millimeter but by whole millimeters, maybe by many millimeters. Darwin s finches worksheet answers showing the 8 best worksheets. But it's the finches who are able to adapt to these changes who survive. Despite the traditional view that species do not exchange genes by hybridization, a new study led by Princeton ecologists Peter and Rosemary Grant show that gene flow between closely related species is more common than previously thought. The simplest possible answer would be that the islands . Other years with substantial amounts of smaller seeds, selection will favour the birds with the smaller beaks.[19].

Their beaks are specific to the type of diet they eat, which in turn is reflective of the food available. Charles Darwin said evolution was too slow to be observed, but modern studies have corrected this assertion. A major drought hit the island in 1977, and 85% of the birds died. 5. Barbara T. The two are best known for their work studying. These two species. He continued: The long-term outcome of the ongoing hybridization between the two species will depend on environmental factors as well as competition.
