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.

The Cocos finch is a member of a group collectively known as Darwin's finches. [5] Although traditionally placed with the buntings and New World sparrows in the family Emberizidae, [6] molecular phylogenetic studies have shown that Darwin's finches are members of the subfamily Coerebinae within the tanager family Thraupidae. [7]
One of the first recorded examples of divergent evolution is the case of Darwin's Finches. During Darwin's travels to the Galápagos Islands, he discovered several different species of finch, living on the different islands. Darwin observed that the finches had different beaks specialized for that species of finches' diet. [11]
[3] [4] The member of the genus form part of a group collectively known as Darwin's finches. [5] Although traditionally placed with the buntings and New World sparrows in the family Emberizidae, [2] molecular phylogenetic studies have shown that Darwin's finches are members of the subfamily Coerebinae within the tanager family Thraupidae.

Big Bird, also known as the Big Bird lineage, is one of the species of Darwin's finches that is exclusively present on Daphne Major of the Galápagos Islands.It originated from a mixed-breed of the Española cactus finch (Geospiza conirostris) and the medium ground finch (Geospiza fortis) that immigrated to Daphne Major in 1981.

They are known for their work with Darwin's finches on Daphne Major, one of the Galápagos Islands. Since 1973, the Grants have spent six months of every year capturing, tagging, and taking blood samples from finches on the island. They have worked to show that natural selection can be seen within a single lifetime, or even within a couple of ...
