B. Rosemary Grant - Böcker

Evolutionary biology has witnessed breathtaking advances in recent years. Some of its most exciting insights have come from the crossover of disciplines as varied as paleontology, molecular biology, ecology, and genetics. This book brings together many of today's pioneers in evolutionary biology to describe the latest advances and explain why a cross-disciplinary and integrated approach to research questions is so essential. Contributors discuss the origins of biological diversity, mechanisms of evolutionary change at the molecular and developmental levels, morphology and behavior, and the ecology of adaptive radiations and speciation. They highlight the mutual dependence of organisms and their environments, and reveal the different strategies today's researchers are using in the field and laboratory to explore this interdependence. Peter and Rosemary Grant--renowned for their influential work on Darwin's finches in the Galapagos--provide concise introductions to each section and identify the key questions future research needs to address. In addition to the editors, the contributors are Myra Awodey, Christopher N. Balakrishnan, Rowan D. H. Barrett, May R. Berenbaum, Paul M.Brakefield, Philip J. Currie, Scott V. Edwards, Douglas J. Emlen, Joshua B. Gross, Hopi E. Hoekstra, Richard Hudson, David Jablonski, David T. Johnston, Mathieu Joron, David Kingsley, Andrew H. Knoll, Mimi A. R. Koehl, June Y. Lee, Jonathan B. Losos, Isabel Santos Magalhaes, Albert B. Phillimore, Trevor Price, Dolph Schluter, Ole Seehausen, Clifford J. Tabin, John N. Thompson, and David B. Wake.

Renowned evolutionary biologists Peter and Rosemary Grant have produced landmark studies of the Galapagos 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 Galapagos 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.

The story of the unorthodox and inspiring life and career of a pioneering biologist Scientist Rosemary Grant’s journey in life has involved detours and sidesteps—not the shortest or the straightest of paths, but one that has led her to the top of evolutionary biology. In this engaging and moving book, Grant tells the story of her life and career—from her childhood love of nature in England’s Lake District to an undergraduate education at the University of Edinburgh through a swerve to Canada and teaching, followed by marriage, children, a PhD at age forty-nine, and her life’s work with Darwin’s finches in the Galápagos islands. Grant’s unorthodox career is one woman’s solution to the problem of combining professional life as a field biologist with raising a family.Grant describes her youthful interest in fossils, which inspired her to imagine another world, distant yet connected in time—and which anticipated her later work in evolutionary biology. She and her husband, Peter Grant, visited the Galápagos archipelago annually for forty years, tracking the fates of the finches on the small, uninhabited island of Daphne Major. Their work has profoundly altered our understanding of how a group of eighteen species has diversified from a single ancestral species, demonstrating that evolution by natural selection can be observed and interpreted in an entirely natural environment. Grant’s story shows the rewards of following a winding path and the joy of working closely with a partner, sharing ideas, disappointments, and successes.
