Darwin's finches are different closely related species which Darwin discovered on the Galapagos Islands. Darwin's [[Second voyage of HMS Beagle|voyage on the ''Beagle'']], and the finches in particular, are known to have influenced his thinking so that he would later produce a basic [[The Origin of Species|theory of evolution by natural selection]]. Darwin reasoned that there had to be a common ancestor. Later, extensive research was done by Peter and Rosemary Grant. The birds are all about the same size (10&ndash;20&nbsp;cm). They mainly differ in the form of the beak. The beak is adapted to the food they eat. The birds are all brownish or black. They have short rounded wings and a rounded tail that often appears cocked to one side. Most male finch mature to a solid black color, while the females mature to a drab grayish color. Exceptions are made for the Vegetarian and Tree Finches the males never become completely black rather they have a black head, neck and upper breast. Warbler, Woodpecker and Mangrove Finches have more of an olive color.

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.

Content

[edit]

In a 1995 review of the book states "In The Beak of the Finch, Jonathan Weiner vividly describes the excitement of modern evolutionary biology through the eyes and activities of two of its most important students, Peter and Rosemary Grant. "[2]

The island Daphne Major where most of the research described in Beak of the Finch takes place

The finches of the title are the Galapagos or 'Darwin's Finches,' passerine songbirds in the Galapagos Islands. The species are so distinct that when Charles Darwin collected them in the islands he thought they were completely different birds, and it was only when he was back in London in 1837 that the ornithologist John Gould revealed that they were closely allied, reinforcing Darwin's growing view that “species are not immutable.” The adaptations of their numerous species, in three genera, show diverging evolution to exploit several ecological niches in the rugged and dry Galápagos Islands.

Weiner follows the careers of two biologists, Peter and Rosemary Grant, and several of their graduate students, including Dolph Schluter, Trevor Price, James (Jamie) Smith, and Peter Boag. The Grants spent more than thirty years (twenty of which are covered in the book) studying the morphology (especially bill shape), reproduction, survival, and behaviour of entire populations of Galapagos finches. Their work revolutionized scientists understanding of the pace of evolution, proving that evolution can be observed in 'real time'. Weiner describes years of painstaking field work on a desert island among the Galapagos, Daphne Major. Following years of intense drought or flooding, the Grants and their students were able to demonstrate all the necessary requirements for natural selection: traits have fitness consequences, respond to selection, and are heritable. Kim Sterelny (2007) cites this rapid natural selection as illustrating an important point about periods of relative stasis in the punctuated equilibrium hypothesis of Niles Eldredge and Stephen Jay Gould: "In claiming that species typically undergo no further evolutionary change once speciation is complete, they are not claiming that there is no change at all between one generation and the next. Lineages do change. But the change between generations does not accumulate. Instead, over time, the species wobbles about its phenotypic mean. Jonathan Weiner's The Beak of the Finch describes this very process".[3]

While the book focuses on the Grant's and Darwin's finches, it also covers work on fruit flies by Dobzhansky (Chaper 12) and Trinidadian guppies led by John Endler (Chapter 6).

In the conclusion the author relates the speed of evolution to the growing resistance of insects to insecticides and of bacteria to penicillin and related anti-bacterial drugs.

Reception

[edit]

The book is well received by biologists, and has been praised for its description of the ups and downs of fieldwork, the excitement of unexpected results, and the growing emphasis on critical statistical analysis to uncover patterns.[4] It received some criticism for over-emphasizing the research by the Grants, e.g. Weiner's claim that they discovered species pairs of sticklebacks in freshwater lakes that were already well-known.[5] But reviews agree that the book is compelling, well written, and an excellent primer on how evolution works.[4][5]
