"Reading this book is like having an engaging conversation with two of the most prominent and charming field biologists of our time. Come listen to their singular adventure, unprecedented insight, and eyewitness account of evolution in action. A terrific must-read for all students of biology, from enthusiasts to experts." --Hopi E. Hoekstra, Harvard University "This masterful work summarizes four decades of research on Darwin's finches by the Grants and their many students and collaborators. The book provides an eloquent illustration of how our general understanding of evolution is advanced by a rigorous, sustained focus on a handful of species on a single island." --Joel G. Kingsolver, University of North Carolina, Chapel Hill "A captivating synthesis of arguably the most important research program in evolutionary biology in the last half century.

From classic work on Darwin's finches decades ago to groundbreaking new discoveries, it's all here. A must-read for any student of evolution." --Jonathan Losos, Harvard University "In this delightful and informative book, Peter and Rosemary Grant bring readers along on their four-decade voyage of discovery into the lives of Darwin's finches in the Galápagos archipelago. This is a book about evolutionary change and the origin of new species. The Grants' story--about themselves, natural history and scientific inquiry, and birds and speciation--will inspire anyone with an interest in the natural world." --Robert E. Ricklefs, University of Missouri, St. Louis "This magnificent book is about the most successful field study on evolution ever conducted--the Darwin finch project on the island of Daphne Major.

There is no other book or team of researchers that tells similar stories with such fine detail and such a clear eye over an equivalent span of time. Defying comparison, 40 Years of Evolution is one for the ages." --Dolph Schluter, University of British Columbia.
