A few million years ago, one species of finch migrated to the rocky Galapagos from the mainland of Central or South America. … This process in which one species gives rise to multiple species that exploit different niches is called adaptive radiation. Why
Why Did Darwin’s Finches Evolve To Life On The Galapagos? The Galápagos finches are ideal subjects for observing the drama of evolution. The islands kept them isolated from competition with other birds on the South American mainland, and each island became its own little world. Why did Darwin’s finches evolved on the Galapagos Islands? The
What Caused The Finches Beaks To Change In Size And Shape? Ongoing field studies have documented rapid changes in these birds’ beak sizes and shapes in response to sudden environmental variations — drought, or human disturbances, for example — yet very few genetic changes have been found that accompany those physical differences between finch species,
Why Would Some Finches Have A Better Chance Of Survival? Finches with big beaks had a better chance of surviving the drought and could thus produce a bigger fraction of the next generation. In other words, natural selection caused the average size of medium ground finch beaks to increase. … Now natural selection favored them.
