Available in PDF, EPUB and Kindle. Book excerpt: The past few years have seen a revolution in our ability to map whole genome DNA from ancient humans. With the ancient DNA revolution, combined with rapid genome mapping of present human populations, has come remarkable insights into our past. This important new data has clarified and added to our knowledge from archaeology and anthropology, helped resolve long-existing controversies, challenged long-held views, and thrown up some remarkable surprises. The emerging picture is one of many waves of ancient human migrations, so that all populations existing today are mixes of ancient ones, as well as in many cases carrying a genetic component from Neanderthals, and, in some populations, Denisovans. David Reich, whose team has been at the forefront of these discoveries, explains what the genetics is telling us about ourselves and our complex and often surprising ancestry. Gone are old ideas of any kind of racial 'purity', or even deep and ancient divides between peoples. Instead, we are finding a rich variety of mixtures. Reich describes the cutting-edge findings from the past few years, and also considers the sensitivities involved in tracing ancestry, with science sometimes jostling with politics and tradition. He brings an important wider message: that we should celebrate our rich diversity, and recognize that every one of us is the result of a long history of migration and intermixing of ancient peoples, which we carry as ghosts in our DNA. What will we discover next?

Download or read book The New American Reality written by Reynolds Farley and published by Russell Sage Foundation. This book was released on 1996-08-30 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A fascinating and authoritative account of American social history since 1960 as viewed through the prism of government statistics....[Farley] uses publicly available data, straight forward methods, and modest...language, to provide more information and insight about recent social trends than any other volume in print." —American Journal of Sociology "A brilliant piece of work. Farley is absolutely masterful at taking tens of thousands of national survey statistics and weaving from them a fascinating and beautifully illustrated tapestry of who we are." —Barry Bluestone, Frank L. Boyden Professor of Political Economy, University of Massachusetts, Boston The New American Reality presents a compelling portrait of an America strikingly different from what it was just forty years ago.Gone is the idealized vision of a two-parent, father-supported Ozzie and Harriet society. In its place is an America of varied races andethnic backgrounds, where families take on many forms and mothers frequently work outside the home. Drawing on a definitive analysis of the past four U.S. censuses, author Reynolds Farley reveals a country that offers new opportunities for a broader spectrum of people, while at the same time generating frustration and apprehension for many who once thought their futures secure. The trends that have so transformed the nation were kindled in the 1960s, a watershed period during which many Americans redefined their attitudes toward the rights of women and blacks. The New American Reality describes the activism, federal policymaking, and legal victories that eliminated overtracial and sexual discrimination. But along with open doors came new challenges. Divorce and out-of-wedlock births grew commonplace, forcing more women to raise children alone and—despite improved wages—increasing their chances of falling into poverty. Residential segregation, inadequate schooling, and a particularly high ratio of female-headed families severely impaired the economic progress of African Americans, many of whom were left behind in declining central cities as businesses migrated to suburbs. A new generation of immigrants from many nations joined the ranks of those working to support families and improve their prospects, and rapidly transformed the nation's ethnic composition. In the 1970s, unprecedented economic restructuring on a global scale created unexpected setbacks for the middle class. The long era of postwar prosperity ended as the nation's dominant industry shifted from manufacturing to services, competition from foreign producers increased, interest rates rose, and a new emphasis on technology and cost-cutting created a demand for more sophisticated skills in the workplace. The economic recovery of the 1980s generated greater prosperity for the well-educated and highly skilled, and created many low paying jobs, but offered little to remedy the stagnant and declining wages of the middle class. Income inequalitybecame a defining feature in the economic life of America: overall, the rich got richer while the poor and middle class found it increasingly difficult to meet their financial demands. The New American Reality reports some good news about America. Our lives are longer and healthier, the elderly are much better off than ever before, consumer spending power has increased, and minorities and women have many more opportunities. But this book does not shy away from the significant problems facing large portions of the population, and provides a valuable perspective on efforts to remedy them. The New American Reality offers the information necessary to understandthe critical trends affecting America today, from how we earn a living to how and when we form families, where we live, and whether or not we will continue to prosper.

Download or read book Blueprint written by Robert Plomin and published by MIT Press. This book was released on 2019-07-16 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: A top behavioral geneticist argues DNA inherited from our parents at conception can predict our psychological strengths and weaknesses. This “modern classic” on genetics and nature vs. nurture is “one of the most direct and unapologetic takes on the topic ever written” (Boston Review). In Blueprint, behavioral geneticist Robert Plomin describes how the DNA revolution has made DNA personal by giving us the power to predict our psychological strengths and weaknesses from birth. A century of genetic research shows that DNA differences inherited from our parents are the consistent lifelong sources of our psychological individuality—the blueprint that makes us who we are. Plomin reports that genetics explains more about the psychological differences among people than all other factors combined. Nature, not nurture, is what makes us who we are. Plomin explores the implications of these findings, drawing some provocative conclusions—among them that parenting styles don't really affect children's outcomes once genetics is taken into effect. This book offers readers a unique insider’s view of the exciting synergies that came from combining genetics and psychology.

Download or read book A Short History of Humanity written by Johannes Krause and published by Random House. This book was released on 2021-04-08 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humanity has often found itself on the precipice. We've survived and thrived because we've never stopped moving... 'Stops you dead in your tracks ... An absolute revelation' Sue Black, bestselling author of All That Remains In this eye-opening book, Johannes Krause, Chair of the Max Planck Institute for the History of Humanity, offers a new way of understanding our past, present and future. Marshalling unique insights from archaeogenetics, an emerging new discipline that allows us to read our ancestors' DNA like journals chronicling personal stories of migration, Krause charts two millennia of adaption, movement and survival, culminating in the triumph of Homo Sapiens as we swept through Europe and beyond in successive waves of migration - developing everything from language, the patriarchy, disease, art and a love of pets as we did so. We also meet our ancestors, from those many of us have heard of - such as Homo Erectus and the Neanderthals - to the wildly unfamiliar but no less real: the recently discovered Denisovans, who ranged across Asia and, like humans, interbred with Neanderthals; the Aurignacians, skilled artists who, 40,000 years ago, brought about an extraordinary transformation in what our species could invent and create; the Varna, who buried their loved ones with gold long before the Pharaohs of Egypt did; and the Gravettians, big game hunters who were Europe's most successful early settlers until they perished in the face of the toughest opponent humanity had ever faced: the ice age. As well as being a radical new telling of our shared story, this book is a reminder that the global problems that keep us awake at night - climate catastrophe; the sudden emergence of deadly epidemics; refugee crises; ethnic conflict; over-population - are all things we've faced, and overcome, before.

Download or read book Origin Story written by David Christian and published by Little, Brown Spark. This book was released on 2018-05-22 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: This New York Times bestseller "elegantly weaves evidence and insights . . . into a single, accessible historical narrative" (Bill Gates) and presents a captivating history of the universe -- from the Big Bang to dinosaurs to mass globalization and beyond. Most historians study the smallest slivers of time, emphasizing specific dates, individuals, and documents. But what would it look like to study the whole of history, from the big bang through the present day -- and even into the remote future? How would looking at the full span of time change the way we perceive the universe, the earth, and our very existence? These were the questions David Christian set out to answer when he created the field of "Big History," the most exciting new approach to understanding where we have been, where we are, and where we are going. In Origin Story, Christian takes readers on a wild ride through the entire 13.8 billion years we've come to know as "history." By focusing on defining events (thresholds), major trends, and profound questions about our origins, Christian exposes the hidden threads that tie everything together -- from the creation of the planet to the advent of agriculture, nuclear war, and beyond. With stunning insights into the origin of the universe, the beginning of life, the emergence of humans, and what the future might bring, Origin Story boldly reframes our place in the cosmos.
