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.

The finch species with smaller beaks struggled to find alternate seeds to eat. [10] The following two years suggested that natural selection could happen very rapidly. Because the smaller finch species could not eat the large seeds, they died off. Finches with larger beaks were able to eat the seeds and reproduce.
Darwin's finches. The Beak of the Finch: A Story of Evolution in Our Time (ISBN 0-679-40003-6) is a 1994 nonfiction book about evolutionary biology, written by Jonathan Weiner. It won the 1995 Pulitzer Prize for General Nonfiction. [1] In 2014, a substantially unchanged 20th-anniversary edition e-book was issued with a preface by the author.
David Lambert Lack FRS [1] (16 July 1910 – 12 March 1973) was a British evolutionary biologist who made contributions to ornithology, ecology, and ethology. [4] His 1947 book, Darwin's Finches, on the finches of the Galapagos Islands was a landmark work as were his other popular science books on Life of the Robin and Swifts in a Tower. [5]
Shakespeare wrote that music was the ‘food of love’ - and that’s all too true if you happen to be a male Darwin finch. The birds have been left unable to attract mates after a fruit fly was ...
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]
The vampire finches of the Galápagos weren’t always the blood-sucking creatures we see today. Just half a million years ago, these birds arrived on Wolf and Darwin islands and entered into a ...
