Medium ground finches have a better chance of survival in their habitat than small ground finches, due to their beak size. [18] The beak size of medium ground finches can evolve in a relatively short period of time, depending on if it is a wet season or dry season. [19] Survival and beak size of the birds are fueled by the environment.

The term "Darwin's finches" was first applied by Percy Lowe in 1936, and popularised in 1947 by David Lack in his book Darwin's Finches. [ 7 ] [ 8 ] Lack based his analysis on the large collection of museum specimens collected by the 1905–06 Galápagos expedition of the California Academy of Sciences, to whom Lack dedicated his 1947 book.
