Why is Galápagos so endlessly fascinating, whether to read about, to visit, or both? Reasons include its menagerie of truly unusual organisms (like tree daisies, marine iguanas, and flightless cormorants), its relatively low human impact (most of its endemic biodiversity is still extant), and its unrivalled role in the history of science ever since Charles Darwin. Exuberant Life offers a contemporary synthesis of what is known about the evolution of the curiously wonderful organisms of Galápagos, of how they are faring in the tumultuous world of human-induced change, and how evolution can guide efforts today for their conservation. In eight case-study chapters, the book looks at each organism’s ancestry, at how and when it came to Galápagos, and how and why it changed since its arrival, all with an eye to its conservation today. Such analysis often provides surprises and suggestions not previously considered, like the potential benefits to joint conservation efforts with tree daisies and tree finches, for example, or ways that a new explanation for peculiar behaviors in Nazca and blue-footed boobies can benefit both species today. In each chapter, a social-ecological systems framework is used, because human influence is always present, and because it allows an explicit link to evolution. We see how the evolutionary fitnesses of Galápagos organisms are now a product of both ecological conditions and human impact, including climate change. Historically, Galápagos has played a central role in the understanding of evolution; what it now offers to teach us about conservation may well prove indispensable for the future of the planet.
