Topic: The Beak of the Finch

  The Beak of the Finch - Wikipedia, the free encyclopedia
The Beak of the Finch: A Story of Evolution in Our Time (ISBN 0679400036) is a book on evolutionary biology written for the layperson by Jonathan Weiner in 1994.
The finches of the title are the Galapagos or 'Darwin's Finches,' passerine songbirds in the Galapagos Islands.
Darwin's voyage on the HMS Beagle, and the finches in particular, are known to have influenced his thinking so that he would later produce a basic theory of evolution by natural selection.

 The Beak of the Finch : A Story of Evolution in Our Time
By making detailed measurements of the various finch species (and individuals) year after year, breeding pair after breeding pair, and generation after generation the Grants are able to see the species wax and wane between becoming more alike and more different.
The Beak of the Finch should be at, or near, the top of everyone's reading list.
We watch as nature alters the beaks of finches from generation to generation to help them survive.

Beak of the Finch details a fascinating study of evolution in action among the emblematic and eponymous Galapagos finches.
Peter and Rosemary Grant's study of the Darwin finches is not the first experimental study of evolution, but it is among the longest running and most thorough, and is, according to Weiner, canonical in its field.
They measured the beaks of the finches that survived, and procreated, and the beaks of the finches that died.

The big-beaked finches just happened to be the ones favored by the particular set of conditions Nature imposed that year.
The Grants found that the offspring of the birds that survived the 1977 drought tended to be larger, with bigger beaks.
Sure enough, the birds best adapted to eat those seeds because of their smaller beaks were the ones that survived and produced the most offspring.

The Beak of the Finch is science writing and therein poses a number of complex questions about humans--naturalists--and the implementation of ornithology and research in the most famous of the Archipelagoes--a string of islands called the Galapagos off the west coast of South America.
Between the beak of the finch big enough to crack caltrop and the beak of the finch that isn't, the difference is only half a millimeter.
Not all cactus finches behave destructively, but the dirty dozen trample on the common good of all and endanger the cactus and thus the total finch population that survives on the cactus flower.

When the beak grows too long the finch eventually loses the ability to eat properly and that leads to a slow death by starvation.
Finches that have suffered from prolonged malnutrition will usually have a lighter colored beak and claws and often the beak will be misshapen or elongated.
With finch in one hand and the nail clippers (same ones as with the beak) in the other you are half way there.

 The Errors of the National Academy of Sciences Booklet - Harun Yahya
The average depth of ground finch beaks on the island-in other words, the distance between the top and bottom of the beak at the point where the beak joins the body-was approximately half a millimeter, or 5%, larger in 1977 compared to 1976.
Taking this as their starting point, the researchers suggested those finches which fed solely on small seeds were weeded out, while those with beaks capable of breaking and opening larger and harder shells survived.
The explanation for the change in the average size of the Galápagos finches' beaks is this: in years of drought when seeds are scarce birds with beaks slightly larger than the average are able to use these more powerful beaks to open the remaining hard and large seeds.

The ground finches studied by the Grants, Geospiza fortis, eats seeds, and a seed-eating finch's most important survival tool is its beak.
When a severe drought reduced the finches to eating larger, tougher seeds, the fortis population on the island plummeted from 1,200 to 180, and the beaks of the next generation were larger than those of the previous one.
It is also true that the Grants' have not observed the creation of a new species, though the drought took fortis beaks a quarter of the way to the size of a larger species of finch that also lives in the Galapagos.

The documented changes in the finches observed over 20 years are variations caused by the ability of the finches to adapt to changing conditions in the environment.
This, coupled with the fact that the Grants and their co-workers were fortunate enough during their 20-year vigil to experience a severe drought and the very opposite, means that it is no surprise that they were able to document some quite rapid changes under selection.
The Grants not only observed hybridization between species of finches which did not interbreed as a rule, but that under certain conditions the hybrids appeared to be fitter than either of the parent populations.

The Beak Of The Finch is a look into the recent refinements of science's understanding of natural selection and the evolutionary process.
The Beak Of The Finch however puts forth a rather shocking refinement to that notion and instead proposes, with an overwhelming amount of evidence, that this is not the case.
The title of the book refers to the beaks of what are known as Darwin's Finches, the finch birds that inhabit various islands of the Galapagos Islands which are located off of the west coast of South America right on the equator.

 The Beak of the Finch: The Story of Evolution in our Time
What they saw was a kind of evolutionary arms race which served to emphasize the interactional nature of selection processes, as changes in the shape of the finch's beaks drove the evolution of their food sources, and vice versa.
The result is that a slight change in beak shape or size can have devastating effects for the survival of individuals, and for their chances of mating and reproducing.
It was also discovered that finch size, and the characteristics of their beaks, are all highly heritable.

Peter and Rosemary Grant spent years observing, tagging, and measuring Galapagos finches and their environment.
For the finches, body size and the size and shape of their beaks are traits that vary in adapting to environmental niches or changes in those niches.
The birds with the best-suited bodies and beaks for the particular environment survive and pass along the successful adaptation from one generation to another through natural selection.

 Book review: The Beak of the Finch
The Beak of the Finch: Evolution in Real Time is consciously and deliberately a hymn of praise to evolution, a drawn-out celebration of what the author perceives as a logical deathblow to creationists, who are represented (I should say misrepresented) smugly and patronisingly.
Most creationists would agree that Darwin’s finches probably came from an ancestral pair or two (which were themselves finches), so the idea that some of the descendant species might hybridize, even to the extent of leading to a new species, is hardly threatening.
The Grants not only observed such hybridization between species of finches which did not interbreed as a rule, but that under certain conditions the hybrids appeared to be fitter than either of the parent populations.

In grammar, a preposition is a word that establishes a relationship betweenan object (usually a noun phrase)and some other part of the sentence, oftenexpressing a location in place or time.
Finches are seed -eating passerine birds, the many species of which are foundchiefly in the northern hemisphere, but also to a limited extent in Africa and South America.
They are small to moderately large and have a strong beak, usually conical and in some species very large.

There is a lot of information about the beaks of the finch but I was never bored.
Since the reader never knows what exactly Weiner is defending, the last part of the book where some of the scientists involved dis others due to religion or being a member of some religious group that, it is implied, feels differently is head-scratchingly vague and out of place.
The bird's beaks grow, shrink, thicken and thin back and forth and in the end there is really no major change.

 The Beak of the Finch: A Story of Evolution in Our Time
The Grants have documented some 13 species of "Darwin's finches," including one that is flightless; one that cohabits with marine iguanas; one, the vampire finch, that lives on blood; one that is entirely vegetarian; and one, the cactus finch, that makes tools with its beak.
The Grants caught and banded thousands of finches and traced their elaborate lineage, enabling them to document the changes that individual species make, primarily to their beaks, in reaction to the environment.
(During prolonged drought, for instance, beaks may become longer and sharper, to reach the tiniest of seeds.) Even more fascinating, the Grants have documented changes in DNA among their birds, suggesting a refutation of creationism, if one were needed, and leading Weiner to declare that "Darwin did not know the strength of his own theory.

 The Beak of the Finch
Darwin himself was the first to describe and marvel over this diverse, yet similar, group of closely related birds that inhabit the Galapagos Islands in a patchwork of species and adaptations.
Darwin was also the first to note how seemingly minute variations in the beaks of different species coincided with very different behaviors and distributions on the islands.
Detailed studies show that seemingly minute differences of only a single millimeter in the depth of a finch's beak can strongly influence that bird's survival, breeding potential, and contribution to the gene pool.

 The Bogus Logic of The Beak of the Finch
Gouldian Finches from Darwin's Voyage of the Beagle, 1839.
The Beak of the Finch is one of a number of studies which show that subtle changes within species can occur in just a few generations when environmental circumstances change.
The Beak of the Finch purports to be a book about the observation of "evolution in our time." The actual observations recorded in the book, however, demonstrate the absence of evolution among the finches of the Galapagos Islands and other species like the peppered and cotton moths, intestinal bacteria, guppies, and fruit flies.

The Beak of the Finch tells the story of two Princeton University scientists - evolutionary biologists - engaged in an extraordinary investigation.
The finches that Darwin took from Galapagos at the time of his voyage on the Beagle led to his first veiled hints about his revolutionary theory.
For more than twenty years they have been monitoring generation after generation of finches on the island of Daphne Major - measuring, weighing, observing, tracking, analyzing on computers their struggle for existence.

The Beak of the Finch: A Story of Evolution in Our Time
This is an extraordinarily well written book about evolution and specifically about the finches of the Galapagos.
The authors spent years of their lives on a secluded island, taking painstakingly detailed measurements of the local finch population (literally checking every bird on the island time and time again), and how it changes in response to local shifts in the environment.

 Beak of the Finch chosen for Ann Arbor/Ypsilanti Reads | Ann Arbor District Library
Jonathan Weiner's The Beak of the Finch was selected as the focus of the Ann Arbor/Ypsilanti Reads 2006.
The Beak of the Finch traces the efforts of Peter and Rosemary Grant, two scientists whose groundbreaking research on Darwin’s Theory of Evolution involved decades of study of thousands of birds on a desert island in the heart of the Galapagos.
Written for the layperson, the book traces the Grant’s observations of Darwin’s finches and the evolutionary impact of climatic and environmental changes on this population, as the scientists obtain amazing new understanding and insights into the world around them.

 The Beak of the Finch
"The Beak of the Finch" by Jonathan Weiner (which I acquired and read because of the review on rpcman’s site) is largely an account of the work of Peter and Rosemary Grant, who have been studying finches in the Galapagos Islands since 1973.
Darwin studied these finches during his travels, and wrote about them in "Origin of the Species".
The finch population of the Galapagos is perfect for a study of evolution in action because of the limited number of species and the closed nature of the ecosystem (since the one island where they focused most of their study is quite isolated).

The study of the Galapagos Finches not only proves the importance of evolution as a contemporary subject but as one that can be observed RIGHT NOW in the world around us.
Through their research since 1973, evolutionary scientists, Peter and Rosemary Grant, have discovered that Darwin's finches are even more interesting than Darwin ever dreamed, and reveal that Darwin may not have known the strengths of his own theory.
"The beak of the finch," Weiner writes, "is an icon of evolution the way the Bohr atom is an icon of modern physics, and the study of either one shows us more primal energy and eternal change than our minds are built to take in.

 Jonathan Weiner: The Beak of the Finch   (Site not responding. Last check: 2007-10-18)
The Galapagos Islands are "nature's laboratory", the only place on earth where you can watch evolution in real time; they already fascinated Charles Darwin when he visited them on his journey on the Beagle.
There are thirteen different species of finches on Galapagos which all evolved on the islands and differ from each other only by the size and forms of their beaks, enabling them to live off the seeds of the plants growing there.
It can be read as an introduction to evolutionary theory, but if you are already well-read in the field, you will still get a lot out of it; The Beak of the Finch should appeal to a wide audience.
