Distinctive stone tools belonging to the Clovis culture established the presence of these early New World people. But are the Clovis tools Asian in origin? Drawing from original archaeological analysis, paleoclimatic research, and genetic studies, noted archaeologists Dennis J. Stanford and Bruce A. Bradley challenge the old narrative and, in the process, counter traditional—and often subjective—approaches to archaeological testing for historical relatedness. The authors apply rigorous scholarship to a hypothesis that places the technological antecedents of Clovis in Europe and posits that the first Americans crossed the Atlantic by boat and arrived earlier than previously thought. Supplying archaeological and oceanographic evidence to support this assertion, the book dismantles the old paradigm while persuasively linking Clovis technology with the culture of the Solutrean people who occupied France and Spain more than 20,000 years ago.

    Since then, deformed frogs have been turning up in lakes around the world. Written by the only journalist granted access to secret hot spots where these deformed frogs are tested, and brainstorming sessions among the researchers, this compelling, fast-paced narrative is the first to offer a complete picture of what is quite possibly a global catastrophe in the making.

    this is one of those rare books that will change your beliefs - and in doing so will change your life. tHE ANt AND tHE FERRARI offers readers a clear, navigable path through the big questions that confront us all today.

    The Los Angeles Times has listed it among the one hundred most influential books published in the last quarter century, Outside Magazine has included it in a survey of books that changed our world, and it has been called the Book of Genesis for environmentalists.

    As Long As Grass Grows gives readers an accessible history of Indigenous resistance to government and corporate incursions on their lands and offers new approaches to environmental justice activism and policy.Throughout 2016, the Standing Rock protest put a national spotlight on Indigenous activists, but it also underscored how little Americans know about the longtime historical tensions between Native peoples and the mainstream environmental movement. Ultimately, she argues, modern environmentalists must look to the history of Indigenous resistance for wisdom and inspiration in our common fight for a just and sustainable future.

    Thomas Homer-Dixon brings to bear his formidable understanding of the urgent problems that confront our world to clarify their scope and deep causes. The Upside of Down provides a vivid picture of the immense stresses that are simultaneously converging on our societies and threatening a breakdown that would profoundly shake civilization. It shows, too, how we can choose a better route into the future. With the immediacy that characterized his award-winning international bestseller, The Ingenuity Gap, Homer-Dixon takes us on a remarkable journey – from the fall of the Roman empire to the devastation of the 9/11 attacks in New York, from Toronto in the 2003 blackout to the ancient temples of Lebanon and the wildfires of California. Incorporating the newest findings from an astonishing array of disciplines, he argues that the great stresses our world is experiencing – global warming, energy scarcity, population imbalances, and widening gaps between rich and poor – can’t be looked at independently. As these stresses combine and converge, the risk of breakdown rises. The first signs are appearing in the wastelands of the Arctic, the mud-clogged streets of Gonaïves, Haiti, and the volatile regions of the Middle East and Asia. But while the consequences of denial in our more perilous world are dire, Homer-Dixon makes clear that we can use our emerging understanding of the complex systems in which we live to avoid catastrophic collapse in a way the Roman empire could not. This vitally important new book shows how, in the face of breakdown, we can still provide for the renewal of our global civilization. We are creating the conditions for catastrophe, but by understanding the underlying principles that make human and natural systems resilient – and by working together to put those principles into effect – we can still limit the severity of collapse and foster regeneration, innovation, and renewal.
