Genetics and the Unsettled Past
Author: Keith Wailoo
Publisher: Rutgers University Press
ISBN: 0813553369
Category : Social Science
Languages : en
Pages : 371
Book Description
Our genetic markers have come to be regarded as portals to the past. Analysis of these markers is increasingly used to tell the story of human migration; to investigate and judge issues of social membership and kinship; to rewrite history and collective memory; to right past wrongs and to arbitrate legal claims and human rights controversies; and to open new thinking about health and well-being. At the same time, in many societies genetic evidence is being called upon to perform a kind of racially charged cultural work: to repair the racial past and to transform scholarly and popular opinion about the “nature” of identity in the present. Genetics and the Unsettled Past considers the alignment of genetic science with commercial genealogy, with legal and forensic developments, and with pharmaceutical innovation to examine how these trends lend renewed authority to biological understandings of race and history. This unique collection brings together scholars from a wide range of disciplines—biology, history, cultural studies, law, medicine, anthropology, ethnic studies, sociology—to explore the emerging and often contested connections among race, DNA, and history. Written for a general audience, the book’s essays touch upon a variety of topics, including the rise and implications of DNA in genealogy, law, and other fields; the cultural and political uses and misuses of genetic information; the way in which DNA testing is reshaping understandings of group identity for French Canadians, Native Americans, South Africans, and many others within and across cultural and national boundaries; and the sweeping implications of genetics for society today.

A Brief History of Genetics
Author: Chris Rider
Publisher: Cambridge Scholars Publishing
ISBN: 1527561305
Category : Science
Languages : en
Pages : 514
Book Description
Biological inheritance, the passage of key characteristics down the generations, has always held mankind’s fascination. It is fundamental to the breeding of plants and animals with desirable traits. Genetics, the scientific study of inheritance, can be traced back to a particular set of simple but ground-breaking studies carried out 170 years ago. The awareness that numerous diseases are inherited gives this subject considerable medical importance. The progressive advances in genetics now bring us to the point where we have unravelled the entire human genome, and that of many other species. We can intervene very precisely with the genetic make-up of our agricultural crops and animals, and even ourselves. Genetics now enables us to understand cancer and develop novel protein medicines. It has also provided us with DNA fingerprinting for the solving of serious crime. This book explains for a lay readership how, where and when this powerful science emerged.

The Gene
Author: Siddhartha Mukherjee
Publisher: Simon and Schuster
ISBN: 1476733538
Category : Medical
Languages : en
Pages : 624
Book Description
The #1 NEW YORK TIMES Bestseller The basis for the PBS Ken Burns Documentary The Gene: An Intimate History Now includes an excerpt from Siddhartha Mukherjee’s new book Song of the Cell! From the Pulitzer Prize–winning author of The Emperor of All Maladies—a fascinating history of the gene and “a magisterial account of how human minds have laboriously, ingeniously picked apart what makes us tick” (Elle). “Sid Mukherjee has the uncanny ability to bring together science, history, and the future in a way that is understandable and riveting, guiding us through both time and the mystery of life itself.” —Ken Burns “Dr. Siddhartha Mukherjee dazzled readers with his Pulitzer Prize-winning The Emperor of All Maladies in 2010. That achievement was evidently just a warm-up for his virtuoso performance in The Gene: An Intimate History, in which he braids science, history, and memoir into an epic with all the range and biblical thunder of Paradise Lost” (The New York Times). In this biography Mukherjee brings to life the quest to understand human heredity and its surprising influence on our lives, personalities, identities, fates, and choices. “Mukherjee expresses abstract intellectual ideas through emotional stories…[and] swaddles his medical rigor with rhapsodic tenderness, surprising vulnerability, and occasional flashes of pure poetry” (The Washington Post). Throughout, the story of Mukherjee’s own family—with its tragic and bewildering history of mental illness—reminds us of the questions that hang over our ability to translate the science of genetics from the laboratory to the real world. In riveting and dramatic prose, he describes the centuries of research and experimentation—from Aristotle and Pythagoras to Mendel and Darwin, from Boveri and Morgan to Crick, Watson and Franklin, all the way through the revolutionary twenty-first century innovators who mapped the human genome. “A fascinating and often sobering history of how humans came to understand the roles of genes in making us who we are—and what our manipulation of those genes might mean for our future” (Milwaukee Journal-Sentinel), The Gene is the revelatory and magisterial history of a scientific idea coming to life, the most crucial science of our time, intimately explained by a master. “The Gene is a book we all should read” (USA TODAY).

Book Description
'A brilliant, authoritative, surprising, captivating introduction to human genetics. You'll be spellbound' Brian Cox This is a story about you. It is the history of who you are and how you came to be. It is unique to you, as it is to each of the 100 billion modern humans who have ever drawn breath. But it is also our collective story, because in every one of our genomes we each carry the history of our species - births, deaths, disease, war, famine, migration and a lot of sex. In this captivating journey through the expanding landscape of genetics, Adam Rutherford reveals what our genes now tell us about human history, and what history can now tell us about our genes. From Neanderthals to murder, from redheads to race, dead kings to plague, evolution to epigenetics, this is a demystifying and illuminating new portrait of who we are and how we came to be. *** 'A thoroughly entertaining history of Homo sapiens and its DNA in a manner that displays popular science writing at its best' Observer 'Magisterial, informative and delightful' Peter Frankopan 'An extraordinary adventure...From the Neanderthals to the Vikings, from the Queen of Sheba to Richard III, Rutherford goes in search of our ancestors, tracing the genetic clues deep into the past' Alice Roberts

Genetic Crossroads
Author: Elise K. Burton
Publisher: Stanford University Press
ISBN: 1503614573
Category : History
Languages : en
Pages : 481
Book Description
The Middle East plays a major role in the history of genetic science. Early in the twentieth century, technological breakthroughs in human genetics coincided with the birth of modern Middle Eastern nation-states, who proclaimed that the region's ancient history—as a cradle of civilizations and crossroads of humankind—was preserved in the bones and blood of their citizens. Using letters and publications from the 1920s to the present, Elise K. Burton follows the field expeditions and hospital surveys that scrutinized the bodies of tribal nomads and religious minorities. These studies, geneticists claim, not only detect the living descendants of biblical civilizations but also reveal the deeper past of human evolution. Genetic Crossroads is an unprecedented history of human genetics in the Middle East, from its roots in colonial anthropology and medicine to recent genome sequencing projects. It illuminates how scientists from Turkey to Yemen, Egypt to Iran, transformed genetic data into territorial claims and national origin myths. Burton shows why such nationalist appropriations of genetics are not local or temporary aberrations, but rather the enduring foundations of international scientific interest in Middle Eastern populations to this day.

A Short History of Medical Genetics
Author: Peter S. Harper
Publisher: Oxford University Press
ISBN: 0195187504
Category : Language Arts & Disciplines
Languages : en
Pages : 570
Book Description
"This book traces the development of genetics in medicine from the first descriptions of inherited diseases more than 300 years ago to the new applications resulting from mapping and sequencing the human genome. It follows both the scientific and the medical advances, focusing especially on those of the past 50 years, which have seen the field of medical genetics emerge as one of the foremost and most rapidly changing medical specialties, now influencing the whole of medicine. It also examines the ethical challenges faced by those working in the field, and describes some of the past disasters that have resulted from these being ignored, notably the abuses of eugenics and the catastrophic destruction of genetics in Soviet Russia. This is the first book of its kind; it is clearly and simply written, and will be valuable to all those who have an interest or concern in the development of medical genetics, as well as those actually working in the field. Historians and social scientists will likewise find this book an important foundation for future detailed studies, which are urgently needed."--BOOK JACKET.

Mapping Human History
Author: Steve Olson
Publisher: Bloomsbury Publishing
ISBN: 9780747560166
Category : Human beings
Languages : en
Pages : 292
Book Description
Until just a few years ago, we knew surprisingly little about the 150,000 or so years of human existence before the advent of writing. Some of the most momentous events in our past - including our origins, our migrations across the globe, and our acquisition of language - were veiled in the uncertainty of 'prehistory'. That veil is being lifted at last by geneticists and other scientists. Mapping Human History is nothing less than an astonishing 'history of prehistory'. Steve Olson travelled through four continents to gather insights into the development of humans and our expansion throughout the world. He describes, for example, new thinking about how centres of agriculture sprang up among disparate foraging societies at roughly the same time. He tells why most of us can claim Julius Caesar and Confucius among our forebears. He pinpoints why the ways in which the story of the Jewish people jibes with, and diverges from, biblical accounts. And using very recent genetic findings, he explodes the myth that human races are a biological reality.

A Troublesome Inheritance
Author: Nicholas Wade
Publisher: Penguin
ISBN: 0698163796
Category : Science
Languages : en
Pages : 249
Book Description
Drawing on startling new evidence from the mapping of the genome, an explosive new account of the genetic basis of race and its role in the human story Fewer ideas have been more toxic or harmful than the idea of the biological reality of race, and with it the idea that humans of different races are biologically different from one another. For this understandable reason, the idea has been banished from polite academic conversation. Arguing that race is more than just a social construct can get a scholar run out of town, or at least off campus, on a rail. Human evolution, the consensus view insists, ended in prehistory. Inconveniently, as Nicholas Wade argues in A Troublesome Inheritance, the consensus view cannot be right. And in fact, we know that populations have changed in the past few thousand years—to be lactose tolerant, for example, and to survive at high altitudes. Race is not a bright-line distinction; by definition it means that the more human populations are kept apart, the more they evolve their own distinct traits under the selective pressure known as Darwinian evolution. For many thousands of years, most human populations stayed where they were and grew distinct, not just in outward appearance but in deeper senses as well. Wade, the longtime journalist covering genetic advances for The New York Times, draws widely on the work of scientists who have made crucial breakthroughs in establishing the reality of recent human evolution. The most provocative claims in this book involve the genetic basis of human social habits. What we might call middle-class social traits—thrift, docility, nonviolence—have been slowly but surely inculcated genetically within agrarian societies, Wade argues. These “values” obviously had a strong cultural component, but Wade points to evidence that agrarian societies evolved away from hunter-gatherer societies in some crucial respects. Also controversial are his findings regarding the genetic basis of traits we associate with intelligence, such as literacy and numeracy, in certain ethnic populations, including the Chinese and Ashkenazi Jews. Wade believes deeply in the fundamental equality of all human peoples. He also believes that science is best served by pursuing the truth without fear, and if his mission to arrive at a coherent summa of what the new genetic science does and does not tell us about race and human history leads straight into a minefield, then so be it. This will not be the last word on the subject, but it will begin a powerful and overdue conversation.

The Century of the Gene
Author: Evelyn Fox KELLER
Publisher: Harvard University Press
ISBN: 0674039432
Category : Science
Languages : en
Pages : 194
Book Description
In a book that promises to change the way we think and talk about genes and genetic determinism, Evelyn Fox Keller, one of our most gifted historians and philosophers of science, provides a powerful, profound analysis of the achievements of genetics and molecular biology in the twentieth century, the century of the gene. Not just a chronicle of biology’s progress from gene to genome in one hundred years, The Century of the Gene also calls our attention to the surprising ways these advances challenge the familiar picture of the gene most of us still entertain. Keller shows us that the very successes that have stirred our imagination have also radically undermined the primacy of the gene—word and object—as the core explanatory concept of heredity and development. She argues that we need a new vocabulary that includes concepts such as robustness, fidelity, and evolvability. But more than a new vocabulary, a new awareness is absolutely crucial: that understanding the components of a system (be they individual genes, proteins, or even molecules) may tell us little about the interactions among these components. With the Human Genome Project nearing its first and most publicized goal, biologists are coming to realize that they have reached not the end of biology but the beginning of a new era. Indeed, Keller predicts that in the new century we will witness another Cambrian era, this time in new forms of biological thought rather than in new forms of biological life.
