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.

"Galápagos is a comprehensive, up-to-date, and profusely illustrated natural history of this spectacular archipelago. Offering much more information than identification guides, the book provides detailed accounts and more than 650 color photographs of the islands' habitats, marine life, reptiles, birds, mammals, and plants, making the book a virtual nature tour of Galápagos. Galápagos experts John Kricher and Kevin Loughlin have thoroughly revised the original text, bringing all the taxonomy up to date and adding a wealth of new information. Individual chapters cover geology, ecology, human history, Darwin's finches and how Darwin came to his theory of natural selection from his visit to the islands, Galápagos tortoises, marine and land iguanas, mammals, seabirds, landbirds, marine life, and conservation challenges and initiatives. The concluding chapter covers each of the individual islands, including landing sites, unique plant and animal species, and points of interest, and serves as a wonderful guide for visitors as they move from island to island or plan a trip to Galápagos."--
