YR 2008 SN 9780691137186 0691137188 AB This volume offers a glimpse into the world of amphibians and reptiles, the first vertebrate creatures to venture forth from the primeval waters millions of years ago, yet which today include species that are the most at risk of extinction. Here the author, a naturalist travels to the far corners of the Earth to tell the epic story of these animals in this companion to the television series. The book tells the history of their pioneering ancestors, the secrets of their astounding success, and the profound implications of their uncertain future. Amphibians and reptiles once ruled the planet, and their descendants exhibit some of the most colorful variety and astounding behavior known to the animal kingdom. What are the origins of these creatures? How have they transformed themselves into the beautiful and bizarre forms found today? In this book, the author gets up close and personal with the living descendants of the first vertebrates ever to colonize the land, and through them traces the fascinating history of their pioneering ancestors. He explains the ways amphibians and reptiles have changed little from their prehistoric forebears while also demonstrating how they have adapted and evolved into diverse new forms, some of them beyond our wildest imaginings. And he also raises awareness of the threats global warming and other man-made environmental changes pose to many of these creatures.
