Offers an evolutionary history of Darwin's finches since their origin almost 3 million years ago. By continuously tracking finch populations over a period of four decades, this title uncovers the causes and consequences of significant events leading to evolutionary changes in species. "This book uses hard won data . . . to draw insightful conclusions about the messy, dynamic, and creative processes of evolutionary change and lineage divergence. It would make an excellent . . . textbook for a college-level course in evolution because it has it all: natural selection, sexual selection, heritability, competition, character displacement, speciation, and extinction. . . . This book is a tribute to the authors themselves."---Michael S. Webster, Evolution
