The Beak of the Finch by Jonathan Weiner
Treehugger founder, Graham Hill bought this Pulitzer Prize-winner en route to the Galapagos and it opened the immensely enjoyable world of layman science reading to him. "Weiner weaves the tale of Darwin’s discovery of evolution into the story of the Grant couple, who have spent the last 20 years studying the evolution of finches and other fauna and flora on the Galapagos Islands. Their major discovery: despite Darwin’s belief that evolution happens over decades, you can actually watch it happen over as little as months or years! The Grants’ close observation of finch beaks allowed them to see the significant changes that occurred year to year. The Galapagos is one of the most incredible places on Earth and this book is a great way to learn about it, and about evolution."
