The Beak of the Finch tells the story of two Princeton University scientists―evolutionary biologists―engaged in an extraordinary investigation. They are watching, and recording, evolution as it is occurring―now―among the very species of Galápagos finches that inspired Darwin’s early musings on the origin of species. They are studying the evolutionary process not through the cryptic medium of fossils but in real time, in the wild, in the flesh.
The finches that Darwin took from Galápagos at the time of his voyage on the Beagle led to his first veiled hints about his revolutionary theory. But Darwin himself never saw evolution as Peter and Rosemary Grant have been seeing it―in the act of happening. 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.
We see the Grants at work on the island among the thousands of living, nesting, hatching, growing birds whose world and lives are the Grants’ primary laboratory. We explore the special circumstances that make the Galápagos archipelago a paradise for evolutionary research: an isolated population of birds that cannot easily fly away and mate with other populations, islands that are the tips of young volcanoes and thus still rapidly evolving as does the life that they support, a food supply changing radically in response to radical variations of climate―so that in a brief span of time the Grants can see the beak of the finch adapt. And we watch the Grants’ team observe evolution at a level that was totally inaccessible to Darwin: the molecular level, as the DNA in the blood samples taken from the birds reveals evolutionary change.
Here, brilliantly and lucidly recounted―with important implications for our own day, when man’s alterations of the environment are speeding the rate of evolutionary changes―is a scientific enterprise in the grand manner, and abstraction made concrete, a theory validated in life.

Amazon.com Review On the Galapagos Islands Charles Darwin gave his first hint at his theory of natural selection, writing about the finches he studied there. In Darwin's time there was no proof of this theoretical mechanism for evolution. Indeed it would have been thought absurd to imagine observing it actually happen; the process was thought to take geological time spans. Weiner, an outstanding science journalist, details research done in the last 20 years that proves otherwise. Biologists Peter and Rosemary Grant have documented the evolution of Darwin's Galapagos finches, demonstrating that it is neither rare nor slow, but can be watched by the hour. Weiner's superb account reads like a thriller and won the 1995 Pulitzer Prize for nonfiction.
From Publishers Weekly For more than 20 years Rosemary and Peter Grant have divided their time between Daphne Major in the Galapagos and Princeton University. On the tiny island they have intensively studied six species of Darwin's ground finches; at Princeton, they analyze their collected data. In following their work Weiner ( Planet Earth ) tells a remarkable story of continuing evolution, and of the painstaking research that reveals it. The Grants documented two dramatic changes in the finches: after a drought in 1977 reduced their numbers by 85%, the surviving birds became larger, in weight, wingspan and beak; after El Nino's floods in 1983, the trend was reversed. The Grants found that during food shortages the difference of one millimeter in the size of a finch's beak could determine its life or death. In his eloquent and richly informative report, Weiner surveys as well research on evolution being done on crossbills, sticklebacks and fruit flies.

From Library Journal This is an account of Peter and Rosemary Grant's research on the microevolutionary modifications that occur in finch beaks as they adapt to environmental changes. Analysis of data collected from 18,000 birds on a Galapagos island over 21 years conclusively demonstrates that the pressures of natural selection are currently altering wild populations. Also, by incorporating others' work on present-day evolutionary variations in fish, insects, and microbes, Weiner (The Next One Hundred Years, LJ 2/1/90) challenges the concept of evolution as a time-frozen process. Harmonized with the writings of Charles Darwin, this book provides the facts to bring alive evolution as an ongoing process. Highly recommended for general collections, but informed readers would do better with Peter Grant's own Ecology and Evolution of Darwin's Finches (Princeton Univ. Pr., 1986).Frank Reiser, Nassau Community Coll., Garden City, N.Y.Copyright 1994 Reed Business Information, Inc.

A great introduction for the student of evolutionary biology, or the layman. Weiner's book destroys two of the greatest myths about evolution. 1. It's slow. 2. It can't be observed. 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. It's almost astonishing to see how simple evolution truly is, how it occurs in quantifiable baby steps that we can see, if we only take the time to carefully observe. Weiner not only demystifies evolution, but makes it as a topic, thoroughly accessible to the interested layman. His prose is neither dry nor technical and in fact, makes for quite an enjoyable read. I wholeheartedly recommend this book.

Nichols-Haining Weiner sets the reader down with the ghost of Darwin, on the Galapagos Islands where the Grants have been studying since 1973. He introduces us to 'Darwin's finches,' the same birds Darwin observed and wrote about in "Origin of the Species".We're introduced to a populationg that is perfect for evolutionary studies--a limited number of species in a closed ecosystem on an isolated island. Darwin couldn't have known what his observations would lead to so many years later, but Weiner shares with us the Grants meticulous study of over 20 generations of finches. Thousands of individual birds were measured, and their progeny tracked. Through this book, we see what they saw--evolution in action.Weiner weaves facts into a nice story. The book is engaging and reads like a novel, so much so that my 13 year-old daughter is now reading it.The conclusions (and no, this isn't a spoiler) are that evolution by natural selection occurs and that selection can occur quickly (it's not always a slow process). Weiner (and the Grants) also touches on speciation in fish populations, and bacterial and viral evolution.This was required reading in an introductory evolution class in college. I hope, someday, students in high school will be assigned this book. It was excellent, and will probably be wrapped up as Christmas gifts for a few of my friends and family.
26 of 26 people found the following review helpful. absolutely first-rate science journalism By Robert J. Crawford Weiner has written a great book on evolutionary science. Instead of a frozen doctrine whose outlines are generally agreed upon as a quasi-religion, Weiner demonstrates how the modalities of evolution - how it actually occurs in nature - are still under investigation. It is a snapshot of an evolving science, carried out over a lifetime of research by two distinguished scientists.One of the particular things they are attempting to observe directly is a speciation event - the creation of a new species of finch - which we long assumed must take place over geologic time and hence is unobservable. But in the process, Weiner reviews the notion of evolution, with fascinating tidbits from Darwin's original research and thoughts on these same finches of the Galopagos. It is a brilliant portrait of the cutting edge in science as well as a detailed review of many basic notions of evolution.It is also a beautifully written book, indeed a masterpiece of elucidation. And it is all hard science, rather than the pseudo-scientific pap that passes for it in so many popular magazines today. While its rigor makes the book a challenge to read, it is well worth the effort.Recommended, one of the best pieces of scientific journalism I ever read.
