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. Illustrations. 40,000 first printing; BOMC, QPB , History Book Club and Natural Science Book Club alternates.

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).

Positively Brilliant
Weiner's The Beak of the Finch is a positively brilliant work on the topic of evolution. 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.

Darwin's fascinating finches.
Although Creationists have long argued that evolution is "only a theory" which cannot be scientifically proven (see, for instance, THE HANDY-DANDY EVOLUTION REFUTER, Wheaton, Illinois), and that whatever processes the Creator used to create, those processes "are not now operating anywhere in the natural universe" (Duane Gish, EVOLUTION? THE FOSSILS SAY NO!), current evolutionary studies are now demonstrating what even Charles Darwin thought was impossible.

Darwin first introduced us to the finches that inhabit the Galapagos Islands in his ORIGIN OF THE SPECIES. 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. Jonathan Weiner's Pulitzer-Prize winning book provides a fine introduction to evolutionary science, while also delivering conclusive proof that evolution is happening "in jittery motion," daily and hourly all around us (pp. 8-9). "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. Yet like the vista of the atoms, the vista of evolution in action, of evolution in the flesh, has enormous implications for our sense of reality, of what life is, and for our sense of power, of what we can do with life" (p. 112). For this reason, Weiner's brilliant book should be considered required reading.

Turn around! Evolution is happening NOW!
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.
