Darwin S Finches

David Lack's classic work on the finches of the Galapagos Islands (Darwin's Finches) was first published in 1947; few books have had such a great impact on evolutionary biology, indeed it is still one of the most succinct and fascinating treatises ever written about the origin of new species. The 1947 version is reproduced with facsimile pages of the original text, tables and line illustrations. The major feature of this reprint is the additional material supplied by Dr Peter Boag and Dr Laurene Ratcliffe who have both completed studies on the Galapagos. The readership will comprise students of evolution and ecology and those interested in the history of evolutionary thought. Amateur ornithologists and tourists visiting the Galapagos Islands will find this account fascinating.

An important look at a groundbreaking forty-year study of Darwin's finches Renowned evolutionary biologists Peter and Rosemary Grant have produced landmark studies of the Galápagos finches first made famous by Charles Darwin. In How and Why Species Multiply, they offered a complete evolutionary history of Darwin's finches since their origin almost three million years ago. Now, in their richly illustrated new book, 40 Years of Evolution, the authors turn their attention to events taking place on a contemporary scale. By continuously tracking finch populations over a period of four decades, they uncover the causes and consequences of significant events leading to evolutionary changes in species. The authors used a vast and unparalleled range of ecological, behavioral, and genetic data—including song recordings, DNA analyses, and feeding and breeding behavior—to measure changes in finch populations on the small island of Daphne Major in the Galápagos archipelago. They find that natural selection happens repeatedly, that finches hybridize and exchange genes rarely, and that they compete for scarce food in times of drought, with the remarkable result that the finch populations today differ significantly in average beak size and shape from those of forty years ago. The authors' most spectacular discovery is the initiation and establishment of a new lineage that now behaves as a new species, differing from others in size, song, and other characteristics. The authors emphasize the immeasurable value of continuous long-term studies of natural populations and of critical opportunities for detecting and understanding rare but significant events. By following the fates of finches for several generations, 40 Years of Evolution offers unparalleled insights into ecological and evolutionary changes in natural environments.

After his famous visit to the Galápagos Islands, Darwin speculated that "one might fancy that, from an original paucity of birds in this archipelago, one species had been taken and modified for different ends." This book is the classic account of how much we have since learned about the evolution of these remarkable birds. Based upon over a decade's research, Grant shows how interspecific competition and natural selection act strongly enough on contemporary populations to produce observable and measurable evolutionary change. In this new edition, Grant outlines new discoveries made in the thirteen years since the book's publication. Ecology and Evolution of Darwin's Finches is an extraordinary account of evolution in action. Originally published in 1986. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Two species come to mind when one thinks of the Galapagos Islands—the giant tortoises and Darwin’s fabled finches. While not as immediately captivating as the tortoises, these little brown songbirds and their beaks have become one of the most familiar and charismatic research systems in biology, providing generations of natural historians and scientists a lens through which to view the evolutionary process and its role in morphological differentiation. In Darwin’s Finches, Kathleen Donohue excerpts and collects the most illuminating and scientifically significant writings on the finches of the Galapagos to teach the fundamental principles of evolutionary theory and to provide a historical record of scientific debate. Beginning with fragments of Darwin’s Galapagos field notes and subsequent correspondence, and moving through the writings of such famed field biologists as David Lack and Peter and Rosemary Grant, the collection demonstrates how scientific processes have changed over time, how different branches of biology relate to one another, and how they all relate to evolution. As Donohue notes, practicing science today is like entering a conversation that has been in progress for a long, long time. Her book provides the history of that conversation and an invitation to join in. Students of both evolutionary biology and history of science will appreciate this compilation of historical and contemporary readings and will especially value Donohue’s enlightening commentary.

"Accessibly written in an engaging style, this book examines classic popular stories in the history of science. Some of the myths discussed include Franklin's Kite, Newton's Apple, and Thomson's plum pudding model of the atom. Martn̕ez successfully holds readers' attention by relying on rich documentation from primary sources to debunk speculations that have become reified over time. He argues that although scientists have disagreed with one another, the disagreements have been productive. Features includes extensive primary source documentation and detailed explanations of how to compare contradictory sources in order to determine which accounts are truly valid"-- Provided by publisher.

Charles Darwin's experiences in the Galápagos Islands in 1835 helped to guide his thoughts toward a revolutionary theory: that species were not fixed but diversified from their ancestors over many generations, and that the driving mechanism of evolutionary change was natural selection. In this concise, accessible book, Peter and Rosemary Grant explain what we have learned about the origin and evolution of new species through the study of the finches made famous by that great scientist: Darwin's finches. Drawing upon their unique observations of finch evolution over a thirty-four-year period, the Grants trace the evolutionary history of fourteen different species from a shared ancestor three million years ago. They show how repeated cycles of speciation involved adaptive change through natural selection on beak size and shape, and divergence in songs. They explain other factors that drive finch evolution, including geographical isolation, which has kept the Galápagos relatively free of competitors and predators; climate change and an increase in the number of islands over the last three million years, which enhanced opportunities for speciation; and flexibility in the early learning of feeding skills, which helped species to exploit new food resources. Throughout, the Grants show how the laboratory tools of developmental biology and molecular genetics can be combined with observations and experiments on birds in the field to gain deeper insights into why the world is so biologically rich and diverse. Written by two preeminent evolutionary biologists, How and Why Species Multiply helps to answer fundamental questions about evolution--in the Galápagos and throughout the world.

PULITZER PRIZE WINNER • A dramatic story of groundbreaking scientific research of Darwin's discovery of evolution that "spark[s] not just the intellect, but the imagination" (Washington Post Book World). “Admirable and much-needed.... Weiner’s triumph is to reveal how evolution and science work, and to let them speak clearly for themselves.”—The New York Times Book Review On a desert island in the heart of the Galapagos archipelago, where Darwin received his first inklings of the theory of evolution, two scientists, Peter and Rosemary Grant, have spent twenty years proving that Darwin did not know the strength of his own theory. For among the finches of Daphne Major, natural selection is neither rare nor slow: it is taking place by the hour, and we can watch. In this remarkable story, Jonathan Weiner follows these scientists as they watch Darwin's finches and come up with a new understanding of life itself. The Beak of the Finch is an elegantly written and compelling masterpiece of theory and explication in the tradition of Stephen Jay Gould.
