Book Description
With all the recent advances in molecular and evolutionary biology, one could almost wonder why we need the fossil record. Molecular sequence data can resolve taxonomic relationships, experiments with fruit flies demonstrate evolution and development in real time, and field studies of Galapagos finches have provided the strongest evidence for natural selection ever measured in the wild. What, then, can fossils teach us that living organisms cannot? Evolutionary Patterns demonstrates the rich variety of clues to evolution that can be gleaned from the fossil record. Chief among these are the major trends and anomalies in species development revealed only by "deep time," such as periodic mass extinctions and species that remain unchanged in form for millions of years. Contributors explore modes of development, the tempo of speciation and extinction, and macroevolutionary patterns and trends. The result is an important contribution to paleobiology and evolutionary biology, and a spirited defense of the fossil record as a crucial tool for understanding evolution and development. The contributors are Ann F. Budd, Efstathia Bura, Leo W. Buss, Mike Foote, Jörn Geister, Stephen Jay Gould, Eckart Hâkansson, Jean-Georges Harmelin, Lee-Ann C. Hayek, Jeremy B. C. Jackson, Kenneth G. Johnson, Nancy Knowlton, Scott Lidgard, Frank K. McKinney, Daniel W. McShea, Ross H. Nehm, Beth Okamura, John M. Pandolfi, Paul D. Taylor, and Erik Thomsen.

Book Description
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.

Book Description
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.

Book Description
This compelling text examines evolution, its definition, the scientific evidence that evolution has taken place, natural selection, Darwin's Origin of Species, genetics and evolution, population genetics, patterns in evolution and species concepts, the story of life and geological time, and human evolution. The easy-to-follow narrative offers students additional biological information in sidebars, such as "Closeup" boxes that give details about main concepts, "Try This" boxes that provide safe experiments for readers to perform, "What Do You Think?" panels that challenge students' reading comprehension, "Applications" boxes that describe how biological knowledge improves daily life, "Red Herring" boxes that profile failed theories, "Hot Debate" panels that spotlight the disagreements and discussions that rage in the biological sciences, and "Genetic Perspective" boxes that summarize the latest genetic research. The text serves as a must-have resource on modern thinking about evolution and the history of evolutionary theories.

Book Description
This volume is a collection of the some of the most significant lectures that well-known experts presented at our two international “summits on evolution” (2005, 2009) as updated and revised chapters. The meetings took place on one of the large islands of the Galapagos archipelago (San Cristobal) at GAIAS (Galapagos Institute for the Arts and Sciences) of the Universidad San Francisco de Quito (USFQ), Ecuador.​ The main goal of the two Galapagos Summits on Evolution has been to bring together scientists and graduate students engaged in the study of evolution, from life’s origin to its current diversity. Because of their historical significance, the Galapagos are a unique venue for promoting comprehensive research on evolution and ecology and to make the research results available to students and teachers everywhere, but especially from developing countries. As shown by the enthusiastic attendance at both summits and the many suggestions to keep them continuing, the meetings have opened new opportunities for students from Ecuador and other Latin American countries to be inspired by some of the most brilliant minds in evolutionary science.

Perspective of This Volume Charles Darwin brought the Galapagos Islands to the attention of zoologists, botanists, and geologists following the six-week visit of H. M. S. Beagle to the islands in 1835. Since then published research on the biota of the islands, partic ularly in multiauthored volumes, has focused on terrestrial plants and animals. The present volume is designed specifically to provide a summary of work on the marine invertebrate fauna. One deviation from that objective was the inclusion of a chapter on land snails, which proved to be a good choice because the phylum Mollusca is now covered more thoroughly in this volume than in any single previous scholarly work on the Galapagos. The academic bottom line with this book is to elucidate the evolutionary responses of shallow water, benthic marine invertebrates to the unique set of insular conditions that exist in the Galapagos Islands. The route taken to that objective has many paths including taxonomic revision, determining biogeo graphic affinities, and examining the ecological requirements of species. The information presented here is for some groups from the islands the first stage in a thorough process that can eventually lead to an understanding of the phylogenetic relationships of these species.
