Book Description
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?

Book Description
A top behavioral geneticist makes the case that DNA inherited from our parents at the moment of conception can predict our psychological strengths and weaknesses. 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. The paperback edition has a new afterword by the author.

Book Description
"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.

Book Description
“The book bursts to life with [Wilson’s] observations of nature, from fire ants and social spiders to starlings.”—Aarathi Prasad, New York Times Book Review An “endlessly fascinating” (Michael Ruse) work of scientific thought and synthesis, Genesis is Edward O. Wilson’s twenty-first-century statement on Darwinian evolution. Asserting that religious creeds and philosophical questions can be reduced to purely genetic and evolutionary components, and that the human body and mind have a physical base obedient to the laws of physics and chemistry, Wilson demonstrates that the only way for us to fully understand human behavior is to study the evolutionary histories of nonhuman species. At least seventeen of these species—among them the African naked mole rat and the sponge-dwelling shrimp—have been found to have advanced societies based on altruism and cooperation. Braiding twenty-first- century scientific theory with the lyrical biological and humanistic observations for which Wilson is beloved, Genesis is “a magisterial history of social evolution, from clouds of midges or sparrows to the grotesqueries of ant colonies” (Kirkus Reviews, starred review).

Book Description
“Thrilling . . . a bracing summary of what we have learned [from] ‘archaeogenetics’—the study of ancient DNA . . . Krause and Trappe capture the excitement of this young field.”—Kyle Harper, The Wall Street Journal Johannes Krause is the director of the Max Planck Institute for Evolutionary Anthropology and a brilliant pioneer in the field of archaeogenetics—archaeology augmented by DNA sequencing technology—which has allowed scientists to reconstruct human history reaching back hundreds of thousands of years before recorded time. In this surprising account, Krause and journalist Thomas Trappe rewrite a fascinating chapter of this history, the peopling of Europe, that takes us from the Neanderthals and Denisovans to the present. We know now that a wave of farmers from Anatolia migrated into Europe 8,000 years ago, essentially displacing the dark-skinned, blue-eyed hunter-gatherers who preceded them. This Anatolian farmer DNA is one of the core genetic components of people with contemporary European ancestry. Archaeogenetics has also revealed that indigenous North and South Americans, though long thought to have been East Asian, also share DNA with contemporary Europeans. Krause and Trappe vividly introduce us to the prehistoric cultures of the ancient Europeans: the Aurignacians, innovative artisans who carved flutes and animal and human forms from bird bones more than 40,000 years ago; the Varna, who buried their loved ones with gold long before the Pharaohs of Egypt; and the Gravettians, big-game hunters who were Europe’s most successful early settlers until they perished in the ice age. Genetics has earned a reputation for smuggling racist ideologies into science, but cutting-edge science makes nonsense of eugenics and “pure” bloodlines. Immigration and genetic exchanges have always defined our species; who we are is a question of culture, not biological inheritance. This revelatory book offers us an entirely new way to understand ourselves, both past and present.

Book Description
Everyone has heard of the story of DNA as the story of Watson and Crick and Rosalind Franklin, but knowing the structure of DNA was only a part of a greater struggle to understand life's secrets. Life's Greatest Secret is the story of the discovery and cracking of the genetic code, the thing that ultimately enables a spiraling molecule to give rise to the life that exists all around us. This great scientific breakthrough has had farreaching consequences for how we understand ourselves and our place in the natural world, and for how we might take control of our (and life's) future. Life's Greatest Secret mixes remarkable insights, theoretical dead-ends, and ingenious experiments with the swift pace of a thriller. From New York to Paris, Cambridge, Massachusetts, to Cambridge, England, and London to Moscow, the greatest discovery of twentieth-century biology was truly a global feat. Biologist and historian of science Matthew Cobb gives the full and rich account of the cooperation and competition between the eccentric characters -- mathematicians, physicists, information theorists, and biologists -- who contributed to this revolutionary new science. And, while every new discovery was a leap forward for science, Cobb shows how every new answer inevitably led to new questions that were at least as difficult to answer: just ask anyone who had hoped that the successful completion of the Human Genome Project was going to truly yield the book of life, or that a better understanding of epigenetics or "junk DNA" was going to be the final piece of the puzzle. But the setbacks and unexpected discoveries are what make the science exciting, and it is Matthew Cobb's telling that makes them worth reading. This is a riveting story of humans exploring what it is that makes us human and how the world works, and it is essential reading for anyone who'd like to explore those questions for themselves.

Book Description
Where did we come from? Where are we going? Homo sapiens is the most successful, the most widespread and the most influential species ever to walk the Earth. In the blink of an evolutionary eye we have spread around the globe, taken control of Earth's biological and mineral resources, transformed the environment, discovered the secrets of the universe and travelled into space. Yet just 7 million years ago, we were just another species of great ape making a quiet living in the forests of East Africa. We do not know exactly what this ancestor was like, but it was no more likely than a chimpanzee or gorilla to sail across the ocean, write a symphony, invent a steam engine or ponder the meaning of existence. How did we get from there to here? The Story of Human Origins recounts the most astonishing evolutionary tale ever told. Discover how our ancestors made the first tentative steps towards becoming human, how we lost our fur but gained language, fire and tools, how we strode out of Africa, invented farming and cities and ultimately created modern civilization - perhaps the only one of its kind in the Universe. Meet your long-lost ancestors, the other humans who once shared the planet with us, and learn where the story might end.

Book Description
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.

Book Description
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?"
