This volume contains 24 papers covering virtually every recent development regarding fossil horses, rhinos, tapirs, and their extinct relatives. It includes material not currently available elsewhere, such as information on the oldest known rhino and the oldest known perissodactyl, as well as papers debunking myths about the evolution of horses, and strong evidence that hyraxes are not related to elephants. The summary chapter includes useful charts which show the relationships of all perissodactyl genera, their distribution in time and space, and a new classification of the order.

What is the "big picture" in environmental science? Our authors know and effectively communicate it in Environmental Science: Systems and Solutions, Sixth Edition. Whether you view the subject through a scientific, social, political, or historical lens, you'll find the concrete foundations here that work for courses in both environmental science and environmental studies. A systems approach is the connective fabric that makes sense of the wealth of topics and data, which demonstrates how aspects of the natural environment interconnect with each other and with human society. A section on Resource Use and Management introduces the concept of sustainability, and another on Dealing with Environmental Degradation discusses threats to the environment and mitigation strategies. A bonus section available online on Social Solutions to Environmental Concerns, discusses the complex issues impacting the environment and the scientific, technologic, and human behavioral ways to address them. Throughout the text you will find the hard data necessary for a scientific study of the environment and the measured analysis ideal for our time.Combining evidence-based, contemporary information and data with relevant case studies, practical applications, numerous calculations, and modern references, Environmental Science: Systems and Solutions teaches and engages.

A new expanded edition of the groundbreaking investigation into early high cultures and ancient solar outbursts• Updated throughout with recent developments and additional illustrations • Reveals how solar outbursts caused the end of the last ice age, unleashed catastrophe upon ancient advanced civilizations, and led to six millennia of a Solar-Induced Dark Age • Includes evidence from solar science, geology, oceanic circulation patterns, the Sphinx, the underground cities of Cappadocia, the Easter Island rongorongo glyphs, and the Göbekli Tepe complex in Turkey In this newly revised and expanded edition, updated throughout with recent developments, geologist Robert Schoch builds upon his revolutionary theory that the origins of the Sphinx date back much further than 2500 BCE and examines scientific evidence of the catastrophe that destroyed early high culture nearly 12,000 years ago. Combining evidence from multiple scientific disciplines, Schoch makes the case that the abrupt end of the last ice age, circa 9700 BCE, was due to an agitated Sun. Solar outbursts unleashed electrical/plasma discharges upon Earth, triggering dramatic climate change as well as increased earthquake and volcanic activity, fires, high radiation levels, and massive floods. Schoch explains how these events impacted the civilizations of the time, set humanity back thousands of years, and led to six millennia of a Solar-Induced Dark Age (SIDA). Applying the SIDA framework to ancient history, he explores how many megalithic monuments, petroglyphs, indigenous traditions, and legends fall logically into place, including the underground cities of Cappadocia, the Easter Island rongorongo glyphs, and the Göbekli Tepe complex in Turkey. He also reveals that our Sun is a much more unstable star than previously believed, suggesting that history could repeat itself with a solar outburst powerful enough to devastate modern society. Weaving together a new view of the origins and antiquity of civilization and the dynamics of the planet we live on, Schoch maintains we must heed the megalithic warning of the past and collectively prepare for future events.

Since the extinction of the dinosaurs, hoofed mammals have been the planet's dominant herbivores. Native to all continents except Australia and Antarctica, they include not only even-toed artiodactyls (pigs, hippos, camels, deer, antelopes, giraffes, sheep, goats, and cattle) and odd-toed perissodactyls (horses and rhinos), but also tethytheres (elephants and their aquatic relatives, manatees and seas cows) and cetaceans (whales and dolphins), which descended from hoofed land mammals. Recent paleontological and biological discoveries have deepened our understanding of their evolution and in some cases have made previous theories obsolete. In Horns, Tusks, and Flippers, Donald R. Prothero and Robert M. Schoch present a compelling new evolutionary history of these remarkable creatures, combining the latest scientific evidence with the most current information about their ecology and behavior. Using an approach based on cladistics, the authors consider both living and extinct ungulates.Included in their discussion are the stories of rhinos, whose ancestors include both dinosaur-sized hornless species and hippo-like river waders; elephants, whose earliest ancestors had neither tusks nor trunks; and whales, whose descent from hoofed mesonychids has never properly been described for the lay audience. Prothero and Schoch also update the evolutionary history of the horse, correcting the frequent errors made in textbooks and popular works, and they make available to the general public new evidence about the evolution of camels, horned antelopes, and cattle. In addition, they raise important conservation issues and relate anecdotes of significant fossil finds. Scientifically accurate and up to date, generously illustrated, and clearly written, Horns, Tusks, and Flippers is a useful and much-needed resource for specialists in the fields of paleontology, zoology, ecology, and evolutionary biology, as well as for general readers interested in learning more about the story of life on earth.
