| the beak of the finch: The Beak of the Finch Jonathan Weiner, 2014-05-14 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. |

| the beak of the finch: Darwin's Finches David Lack, 1983-01-28 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. |
| the beak of the finch: Time, Love , Memory Jonathan Weiner, 2014-05-14 The story of Nobel Prize–winning discoveries regarding the molecular mechanisms controlling the body’s circadian rhythm. How much of our fate is decided before we are born? Which of our characteristics is inscribed in our DNA? Weiner brings us into Benzer's Fly Rooms at the California Institute of Technology, where Benzer, and his asssociates are in the process of finding answers, often astonishing ones, to these questions. Part biography, part thrilling scientific detective story, Time, Love, Memory forcefully demonstrates how Benzer's studies are changing our world view--and even our lives. Jonathan Weiner, winner of the Pulitzer Prize for The Beak of the Finch, brings his brilliant reporting skills to the story of Seymour Benzer, the Brooklyn-born maverick scientist whose study of genetics and experiments with fruit fly genes has helped revolutionize or knowledge of the connections between DNA and behavior both animal and human. |

| the beak of the finch: Revelation Through Science James G. Martin, 2016-11-09 Revelation through Science is written for the educated non-scientist who may be troubled by apparent conflicts between science and religion. Are science and faith incompatible? Astronomers, physicists, and biologists have now shown that the more deeply science probes nature, the more it reveals evidence pointing us to God. After reviewing concepts from those fields, Revelation through Science adds new material from chemistry. It describes organic structures that are profoundly vital for life, yet too complex for self-assembly without some guiding principle. It should lift the burden from believers and seekers to realize that science is not the enemy of faith. |
| the beak of the finch: Ecology and Evolution of Darwin's Finches (Princeton Science Library Edition) Peter R. Grant, 2017-03-14 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. |

| the beak of the finch: Charles Darwin Gavin de Beer, 2017-05-30 Excerpt from Charles Darwin: Evolution by Natural Selection My introduction to the name of Darwin took place nearly sixty years ago in Paris, where I used to be taken from i'ny home in the Rue de la Paix to play in the Gardens of the Tuileries. On the way, in the Rue saint-honore near the corner of the Rue de Castiglione, was a Shop that called itself Articles pour chz'ens and sold dog collars, harness, leads, raincoats, greatcoats With little pockets for handker chiefs, and buttoned boots made of india - rubber, the pair for fore - paws larger than the pair for hind-paws. One day this heavenly shop produced a catalogue, and although I have long since lost it, I remember its introduction as vividly as if I had it before me. It began, 'on sait depuis Darwin que nous descendons des singes, ce qui nous'fait encore plus aimer nos chiens.' I asked, 'qu'est ce que ca veut dire, Darre-vingt?' My father came to the rescue and told me that Darwin was a famous Englishman who had done something or other that meant nothing to me at all; but I recollect that because Darwin was English and a great man, it all fitted perfectly into my pattern of life, which was built on the principle that if anything was English it must be good. I have learnt better since then, but Darwin, at any rate, has never let me down. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

| the beak of the finch: Winning Sustainability Strategies Benoit Leleux, Jan van der Kaaij, 2018-11-11 Despite recent optimism and global initiatives, the implementation of corporate sustainability programs has been slow at best, with less than a third of global companies having developed a clear business case for their approach to sustainability. Presenting numerous award-winning cases and examples from companies such as Unilever, Patagonia, Tumi, DSM and Umicore alongside original ideas based upon 20 years of consulting experience, this book reveals how to design and implement a stronger sense of focus and move sustainability programs forward. This proven combination of purpose, direction and speed is dubbed “Vectoring”. Based upon practitioner cases and data analysis from the Dow Jones Sustainability Index, Vectoring offers a plain-spoken framework to identify the relative position of companies compared to their peers. The framework and its 4 archetypes deliver insights for practitioners to locate inhibitors and overcome them by providing practical suggestions for process improvements. This includes designing and executing new sustainability programs, embedding the SDGs within company strategy and assessing the impact of sustainability programs on competitiveness and valuation. Offering directions for CFOs to shift companies from integrated reporting to integrated thinking in order to accelerate their sustainability programs, Winning Sustainability Strategies shows how to achieve purpose with profit and how to do well by doing good. |

| the beak of the finch: Adaptation and Natural Selection George Christopher Williams, 2018-10-30 Biological evolution is a fact—but the many conflicting theories of evolution remain controversial even today. When Adaptation and Natural Selection was first published in 1966, it struck a powerful blow against those who argued for the concept of group selection—the idea that evolution acts to select entire species rather than individuals. Williams’s famous work in favor of simple Darwinism over group selection has become a classic of science literature, valued for its thorough and convincing argument and its relevance to many fields outside of biology. Now with a new foreword by Richard Dawkins, Adaptation and Natural Selection is an essential text for understanding the nature of scientific debate. |

| the beak of the finch: The Story of the Human Body Daniel Lieberman, 2014-07-01 A landmark book of popular science that gives us a lucid and engaging account of how the human body evolved over millions of years—with charts and line drawings throughout. “Fascinating.... A readable introduction to the whole field and great on the making of our physicality.”—Nature In this book, Daniel E. Lieberman illuminates the major transformations that contributed to key adaptations to the body: the rise of bipedalism; the shift to a non-fruit-based diet; the advent of hunting and gathering; and how cultural changes like the Agricultural and Industrial Revolutions have impacted us physically. He shows how the increasing disparity between the jumble of adaptations in our Stone Age bodies and advancements in the modern world is occasioning a paradox: greater longevity but increased chronic disease. And finally—provocatively—he advocates the use of evolutionary information to help nudge, push, and sometimes even compel us to create a more salubrious environment and pursue better lifestyles. |
| the beak of the finch: Eager Ben Goldfarb, 2018 Our modern idea of what a healthy landscape looks like and how it functions is distorted by the fur trade that once trapped out millions of beavers from North America's lakes and rivers. Goldfarb shares the powerful story about one of the world's most influential species. He explains how North America was colonized, how our landscapes have changed over the centuries, and how beavers can help us fight drought, flooding, wildfire, extinction, and the ravages of climate change. -- adapted from jacket |
| the beak of the finch: Indica Pranay Lal, 2016-12-07 Few places have been as influential as the Indian subcontinent in shaping the course of life on Earth. Yet its evolution has remained largely unchronicled. Indica: A Deep Natural History of the Indian Subcontinent fills this gap. From the oldest rocks, formed three billion years ago in Karnataka, to the arrival of our ancestors 50,000 years ago on the banks of the Indus, the author meticulously sifts through wide-ranging scientific disciplines and through the layers of earth to tell us the story of India, filled with a variety of fierce reptiles, fantastic dinosaurs, gargantuan mammals and amazing plants. Beautifully produced in full colour, with a rare collection of images, illustrations and maps, Indica is full of fascinating, lesser-known facts. It shows us how every piece of rock and inch of soil is a virtual museum, and how, over billions of years, millions of spectacular creatures have reproduced, walked and lived over and under it. |

| the beak of the finch: The Galapagos Henry Nicholls, 2014-03-13 Formed of dramatic volcanic scenery and home to marvellous beasts, it is little wonder that the first name for the Galápagos archipelago was Las Encantadas: the enchanted islands. In this captivating natural history, Henry Nicholls builds up the ecology of these famous islands, from their explosive origins to the arrival of the archipelago's celebrated reptiles and ultimately humans. It's a story of change, as the islands are transformed from lava-strewn wilderness into a vital scientific resource and a sought-after destination for eco-enthusiasts. Charles Darwin's five-week visit to the Galápagos in 1835 played a pivotal role in this transformation. At the time, he was more interested in rocks than finches, took the opportunity to ride on the backs of tortoises and fling iguanas into the sea. Yet the Galápagos experience can be an inspiration and it certainly was for Darwin, pointing him towards one of the most important and influential ideas in the history of humankind: evolution by natural selection. And with the Darwin connection, the Galápagos found itself propelled onto a global stage. But worldwide fame has brought with it nearly 200,000 tourists a year and a human population now estimated at around 30,000. If Darwin learned from the Galápagos, so we must too. For what happens here in years to come foreshadows the fate of threatened ecosystems everywhere on earth. |

| the beak of the finch: The End of the Myth Greg Grandin, 2019-03-05 WINNER OF THE PULITZER PRIZE A new and eye-opening interpretation of the meaning of the frontier, from early westward expansion to Trump’s border wall. Ever since this nation’s inception, the idea of an open and ever-expanding frontier has been central to American identity. Symbolizing a future of endless promise, it was the foundation of the United States’ belief in itself as an exceptional nation – democratic, individualistic, forward-looking. Today, though, America hasa new symbol: the border wall. In The End of the Myth, acclaimed historian Greg Grandin explores the meaning of the frontier throughout the full sweep of U.S. history – from the American Revolution to the War of 1898, the New Deal to the election of 2016. For centuries, he shows, America’s constant expansion – fighting wars and opening markets – served as a “gate of escape,” helping to deflect domestic political and economic conflicts outward. But this deflection meant that the country’s problems, from racism to inequality, were never confronted directly. And now, the combined catastrophe of the 2008 financial meltdown and our unwinnable wars in the Middle East have slammed this gate shut, bringing political passions that had long been directed elsewhere back home. It is this new reality, Grandin says, that explains the rise of reactionary populism and racist nationalism, the extreme anger and polarization that catapulted Trump to the presidency. The border wall may or may not be built, but it will survive as a rallying point, an allegorical tombstone marking the end of American exceptionalism. |

A Charm of Finches follows Javier Landes as he retires from escorting and invites love to be his friend. He meets an art therapist named Steffen Finch and what starts as casual deepens into a passionate relationship—everything Jav has ever wanted, and everything he fears losing. Stef’s business card reads Curator & Sailor. His creativity and insightful nature have made him into a talented therapist, the one to call for tough cases. His professional success can’t conceal a deep need to connect with someone, but Javier Landes is the last person Stef expected. Geronimo Geno Caan is Stef's most challenging case. To cope with his ordeal, he's allowed an alter-ego called Mos to make decisions, and now lives a double life within a web of lies. Under Stef’s navigation, Geno uses art to express what Mos forbids to be spoken aloud. But as Geno’s attachment to Stef gradually extends to Jav, the boundaries between professional and personal begin to blur. Over the course of a year, Jav, Stef and Geno form an unexpected and unconventional triangle, revealing how men make love in times of war and how love is a great wisdom made up of small understandings. A Charm of Finches is an epic tale of survival and secrets guaranteed to make you think and feel and remember. |
| the beak of the finch: Amity and Prosperity Eliza Griswold, 2018-06-12 Winner of the 2019 Pulitzer Prize for General Nonfiction In Amity and Prosperity, the prizewinning poet and journalist Eliza Griswold tells the story of the energy boom’s impact on a small town at the edge of Appalachia and one woman’s transformation from a struggling single parent to an unlikely activist. Stacey Haney is a local nurse working hard to raise two kids and keep up her small farm when the fracking boom comes to her hometown of Amity, Pennsylvania. Intrigued by reports of lucrative natural gas leases in her neighbors’ mailboxes, she strikes a deal with a Texas-based energy company. Soon trucks begin rumbling past her small farm, a fenced-off drill site rises on an adjacent hilltop, and domestic animals and pets start to die. When mysterious sicknesses begin to afflict her children, she appeals to the company for help. Its representatives insist that nothing is wrong. Alarmed by her children’s illnesses, Haney joins with neighbors and a committed husband-and-wife legal team to investigate what’s really in the water and air. Against local opposition, Haney and her allies doggedly pursue their case in court and begin to expose the damage that’s being done to the land her family has lived on for centuries. Soon a community that has long been suspicious of outsiders faces wrenching new questions about who is responsible for their fate, and for redressing it: The faceless corporations that are poisoning the land? The environmentalists who fail to see their economic distress? A federal government that is mandated to protect but fails on the job? Drawing on seven years of immersive reporting, Griswold reveals what happens when an imperiled town faces a crisis of values, and a family wagers everything on an improbable quest for justice. |

When her father leaves and her mother passes away soon afterward, Finch can’t help feeling abandoned. Now she’s stuck living with her stepfather and his new wife. They’re mostly nice, but they don’t believe the one true thing Finch knows about herself: that she’s a girl, even though she was born in a boy’s body. Thankfully, she has Maddy, a neighbor and animal rescuer who accepts her for who she is. Finch helps Maddy care for a menagerie of lost and lonely creatures, including a scared, stray dog who needs a family and home as much as she does. As she earns the dog’s trust, Finch realizes she must also learn to trust the people in her life—even if they are the last people she expected to love her and help her to be true to herself.

the drought as its beak size did not change. Possibly it had lost the genetic information to make a smaller beak. G.fortis apparently still had this genetic information and its beak size has declined since the drought, making it better able to compete for the food sources available. (Although this seems contradictory to what occurred in
