Biospeleology, the study of organisms that live in caves, has a tremendous potential to inform many aspects of modern biology; yet this area of knowledge remains largely anchored in neo-Lamarckian views of the natural world in both its approaches and jargon. Written for graduate students and academic researchers, this book provides a critical examination of current knowledge and ideas on cave biology, with emphasis on evolution, ecology, and conservation. Aldemaro Romero provides a historical analysis of ideas that have influenced biospeleology, discusses evolutionary phenomena in caves, from cave colonization to phenotypic and genotypic changes, and integrates concepts and knowledge from diverse biological viewpoints. He challenges the conventional wisdom regarding the biology of caves, and highlights urgent questions that should be addressed in order to get a better and more complete understanding of caves as ecosystems.

The harsh environment of caves--dark, damp, sparse of food--is home to a variety of "bizarre" creatures. Biologists, for their part, often treat these delicate, colorless organisms having no eyes, or at least greatly reduced eyes, as mere oddities with little to tell us about a topic as grand as evolution. Focusing on one cave-dwelling crustacean, Gammarus minus, this book shows that, to the contrary, cave life can provide a valuable empirical model for the study of evolution, particularly adaptation. Authors David Culver, Thomas Kane, and Daniel Fong marshal many years of extensive research into the genetics, ecology, morphology, and systematics of Gammarus minus. They explain how these biological factors have been shaped by physical constraints, such as the structure and development of caves and karst terrains, groundwater hydrology, and drainage basin patterns. Their work reveals the advantages of caves for studying natural selection: the highly simplified habitats found underground serve as a natural laboratory for the evolutionary biologist, and the distinctive morphological features of cave fauna provide a wealth of data on evolutionary history and natural selection. A detailed evolutionary study of a single organism in a particular environment, this book advances Gammarus minus as a paradigm for cave colonization and adaptation, and as a general case study of the role of natural selection and adaptation in evolution.

This groundbreaking study explores the evolution of cave-dwelling animals in America, and the unique adaptations they have developed in response to their environment. Drawing on years of fieldwork and research, the author provides a detailed account of the anatomy, behavior, and genetics of these remarkable creatures, as well as their ecological significance. With its wealth of information and fascinating insights, this book is a must-read for anyone interested in the evolution of life on Earth.

Excerpt from Cave Vertebrates of America: A Study in Degenerative Evolution A cave is a unit of environment so well circumscribed and of such simplicity that we may know its contents, its elements, and its conditions nearly as well as the experimental zoologist knows the contents and conditions of his aquarium. These contents and conditions are of rare uniformity, changing but little from day to night, from season to season, or from decade to decade. The point of chief interest in the cave environment is the total absence of light in all parts except about its mouth. Probably no animals have a more intimate environmental adaptation than those inhabiting caves. This adaptation is largely of color and structure of eye, which modifications are surpassed only by the functional adapta tion of the tactile apparatus of the blind forms. While no one has followed, and although we may not be able to follow in detail, the steps through which the cave animal has acquired this environmental adaptation, a knowledge of the present condition of their unchanging environment gives us a knowledge of what it has been during their entire period of development. We know, or can know, what the present stage of their adaptation is. Not in frequently we know what the condition of the animal was at the start of its cave experiences and enough of the steps along its line of evolution (indicated by the degrees of adaptation reached by different members of the group) to enable us to form so clear a picture of its entire route of evolution that we may conjecture what elements of the environment caused the modifications, and by what process they were brought about. We have, in other words, a long experiment conducted by nature unrolled before us. I propose in this work to give an account of the cave as an environment; to bring together in a revised form the papers on blind and cave vertebrate animals so far published by myself and my students, together with further observations on the species previously considered, to consider the habitat, mode of life, and the origin of the Cuban blind fishes, and to give an account of their eyes.

Cave exploration has uncovered archaeological finds which have enhanced our understanding of human evolution, and fossil remains, such as woolly mammoths, which reveal something of the Pleistocene animal world. But perhaps most fascinating of all is the living natural history of caves.
