The different finch species found on the Galápagos Islands probably arose as a result of _____. Darwin's finches (also known as the Galápagos finches) are a group of about 18 species of passerine birds. They are well known for their remarkable diversity in beak form and function. They are often classified as the subfamily Geospizinae or tribe Geospizini. They belong to the tanager family and are not closely related to the true finches. The closest known relative of the Galápagos finches is the South American Tiaris obscurus. They were first collected by Charles Darwin on the Galápagos Islands during the second voyage of the Beagle. Apart from the Cocos finch which is from Cocos Island the others are found only on the G… They belong to the tanager family and are not closely related to the true finches. The closest known relative of the Galápagos finches is the South American Tiaris obscurus. They were first collected by Charles Darwin on the Galápagos Islands during the second voyage of the Beagle. Apart from the Cocos finch which is from Cocos Island the others are found only on the Galápagos Islands. 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. 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 birds vary in size from 10 to 20 cm and weigh between 8 and 38 grams. The smallest are the warbler-finches and the largest is the vegetarian finch . The most important differences between species are in the size and shape of their beaks which are highly adapted to different food sources. The birds are all dull-coloured. Darwin's finches - Wikipedia Darwin's finches - Wikipedia Adaptive radiation - Wikipedia Darwin's finches - Wikipedia A 2020 study found there to be no direct causal relationship between the proportionally most comparable mass radiations and extinctions in terms of "co-occurrence of species " substantially challenging the hypothesis of "creative mass extinctions".. Examples Darwin's finches . Darwin's finches are an often-used textbook example of adaptive radiation. The Inaccessible Island rail (Laterallus rogersi) is a small bird of the rail family Rallidae. Endemic to Inaccessible Island in the Tristan Archipelago in the isolated south Atlantic it is the smallest extant flightless bird in the world. The species was described by physician Percy Lowe in 1923 but had first come to the attention of scientists 50 years earlier. Table Mounta...
