Who were the first humans to inhabit North America? According to the now familiar story, mammal hunters entered the continent some 12,000 years ago via a land bridge that spanned the Bering Sea. 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.

AN INSTANT NEW YORK TIMES BESTSELLER! From celebrated anthropologist Jennifer Raff comes the untold story—and fascinating mystery—of how humans migrated to the Americas. ORIGIN is the story of who the first peoples in the Americas were, how and why they made the crossing, how they dispersed south, and how they lived based on a new and powerful kind of evidence: their complete genomes. ORIGIN provides an overview of these new histories throughout North and South America, and a glimpse into how the tools of genetics reveal details about human history and evolution. 20,000 years ago, people crossed a great land bridge from Siberia into Western Alaska and then dispersed southward into what is now called the Americas. Until we venture out to other worlds, this remains the last time our species has populated an entirely new place, and this event has been a subject of deep fascination and controversy. No written records—and scant archaeological evidence—exist to tell us what happened or how it took place. Many different models have been proposed to explain how the Americas were peopled and what happened in the thousands of years that followed. A study of both past and present, ORIGIN explores how genetics is currently being used to construct narratives that profoundly impact Indigenous peoples of the Americas. It serves as a primer for anyone interested in how genetics has become entangled with identity in the way that society addresses the question "Who is indigenous?"

Offering a balanced approach to problem-solving issues in a complex and changing world, this book focuses specifically on the subject of problem solving in policing. Featured selections include chapters on domestic security, disorderly youth, auto theft, prostitution, gang delinquency and crime in public housing. Other notable selections discuss the role of supervising police personnel engaged in problem solving, advances in using this approach in criminal investigations, solving serial crimes, preparing for terrorism, and developing patrol officers as effective first responders to active violence.

Nine psychics have come together to form a group of individuals with similar traits. Fleeing China aboard a stolen jet, they have eluded their military pursuers and now search for a home - a secluded place to live out their life away from the rest of humanity. Yet even as they leave China behind, the group cannot decide which direction to fly. "We must establish a base if we are to survive," the group's founder Michael Tyler insists. However, no one can agree on a single vision. Each psychic has his or her own idealistic version of a utopian society they would build. Each psychic is full of unanswered questions. Where should they start this psychic town? Will their special power give them enough advantage to begin a new community? What place on the planet can provide enough isolation to shield the group from humanity's curious yet judgmental eyes? As they struggle to determine their purpose and their future, they must also find a niche for their individual strengths. So begins Book II of "The Voices Saga," as author William L Stolley seeks a permanent home for his ongoing cast of nine characters: American Michael Tyler, sole survivor of his father's estate; Cecilia Beaton, the Canadian high school graduate; Villi the Russian ex-cop who loves to work on cars; the rest from China: Master Li the ex-professor of English, Han the bureaucratic strategist, Zinian and Zhiwei freshman friends at college, Su Lin the student who loves to cook, and Chou the second year math student. How will this disparate group of individuals fit together to form a working community? A spark of light appears on the horizon and the answers to all of their questions become abundantly clear.
