Book Description
This book examines the wide range of scientific and social arenas in which the concept of inheritance gained relevance in the late nineteenth and early twentieth centuries. Although genetics emerged as a scientific discipline during this period, the idea of inheritance also played a role in a variety of medical, agricultural, industrial, and political contexts. The book, which follows an earlier collection, Heredity Produced (covering the period 1500 to 1870), addresses heredity in national debates over identity, kinship, and reproduction; biopolitical conceptions of heredity, degeneration, and gender; agro-industrial contexts for newly emerging genetic rationality; heredity and medical research; and the genealogical constructs and experimental systems of genetics that turned heredity into a representable and manipulable object. Taken together, the essays in Heredity Explored show that a history of heredity includes much more than the history of genetics, and that knowledge of heredity was always more than the knowledge formulated as Mendelism. It was the broader public discourse of heredity in all its contexts that made modern genetics possible.

Heredity under the Microscope
Author: Soraya de Chadarevian
Publisher: University of Chicago Press
ISBN: 022668511X
Category : Science
Languages : en
Pages : 318
Book Description
By focusing on chromosomes, Heredity under the Microscope offers a new history of postwar human genetics. Today chromosomes are understood as macromolecular assemblies and are analyzed with a variety of molecular techniques. Yet for much of the twentieth century, researchers studied chromosomes by looking through a microscope. Unlike any other technique, chromosome analysis offered a direct glimpse of the complete human genome, opening up seemingly endless possibilities for observation and intervention. Critics, however, countered that visual evidence was not enough and pointed to the need to understand the molecular mechanisms. Telling this history in full for the first time, Soraya de Chadarevian argues that the often bewildering variety of observations made under the microscope were central to the study of human genetics. Making space for microscope-based practices alongside molecular approaches, de Chadarevian analyzes the close connections between genetics and an array of scientific, medical, ethical, legal, and policy concerns in the atomic age. By exploring the visual evidence provided by chromosome research in the context of postwar biology and medicine, Heredity under the Microscope sheds new light on the cultural history of the human genome.

Genetics in the Madhouse
Author: Theodore M. Porter
Publisher: Princeton University Press
ISBN: 0691203237
Category : History
Languages : en
Pages : 462
Book Description
"In the early 1800s, a century before there was any concept of the gene, physicians in insane asylums began to record causes of madness in their admission books. Almost from the beginning, they pointed to heredity as the most important of these causes. As doctors and state officials steadily lost faith in the capacity of asylum care to stem the terrible increase of insanity, they began emphasizing the need to curb the reproduction of the insane. They became obsessed with identifying weak or tainted families and anticipating the outcomes of their marriages. Genetics in the Madhouse is the untold story of how the collection and sorting of hereditary data in mental hospitals, schools for 'feebleminded' children, and prisons gave rise to a new science of human heredity. In this compelling book, Theodore Porter draws on untapped archival evidence from across Europe and North America to bring to light the hidden history behind modern genetics. He looks at the institutional use of pedigree charts, censuses of mental illness, medical-social surveys, and other data techniques--innovative quantitative practices that were worked out in the madhouse long before the manipulation of DNA became possible in the lab. Porter argues that asylum doctors developed many of the ideologies and methods of what would come to be known as eugenics, and deepens our appreciation of the moral issues at stake in data work conducted on the border of subjectivity and science. A bold rethinking of asylum work, Genetics in the Madhouse shows how heredity was a human science as well as a medical and biological one"--Jacket.

Charles Darwin played a crucial part in turning heredity into a scientific question, and yet he failed spectacularly to answer it. The birth of genetics in the early 1900s seemed to do precisely that. Gradually, people translated their old notions about heredity into a language of genes. As the technology for studying genes became cheaper, millions of people ordered genetic tests to link themselves to missing parents, to distant ancestors, to ethnic identities... But, Zimmer writes, “Each of us carries an amalgam of fragments of DNA, stitched together from some of our many ancestors. Each piece has its own ancestry, traveling a different path back through human history. A particular fragment may sometimes be cause for worry, but most of our DNA influences who we are—our appearance, our height, our penchants—in inconceivably subtle ways.” Heredity isn’t just about genes that pass from parent to child. Heredity continues within our own bodies, as a single cell gives rise to trillions of cells that make up our bodies. We say we inherit genes from our ancestors—using a word that once referred to kingdoms and estates—but we inherit other things that matter as much or more to our lives, from microbes to technologies we use to make life more comfortable. We need a new definition of what heredity is and, through Carl Zimmer’s lucid exposition and storytelling, this resounding tour de force delivers it. Weaving historical and current scientific research, his own experience with his two daughters, and the kind of original reporting expected of one of the world’s best science journalists, Zimmer ultimately unpacks urgent bioethical quandaries arising from new biomedical technologies, but also long-standing presumptions about who we really are and what we can pass on to future generations.

Disputed Inheritance
Author: Gregory Radick
Publisher: University of Chicago Press
ISBN: 0226822710
Category : Science
Languages : en
Pages : 643
Book Description
A root-and-branch rethinking of how history has shaped the science of genetics. In 1900, almost no one had heard of Gregor Mendel. Ten years later, he was famous as the father of a new science of heredity—genetics. Even today, Mendelian ideas serve as a standard point of entry for learning about genes. The message students receive is plain: the twenty-first century owes an enlightened understanding of how biological inheritance really works to the persistence of an intellectual inheritance that traces back to Mendel’s garden. Disputed Inheritance turns that message on its head. As Gregory Radick shows, Mendelian ideas became foundational not because they match reality—little in nature behaves like Mendel’s peas—but because, in England in the early years of the twentieth century, a ferocious debate ended as it did. On one side was the Cambridge biologist William Bateson, who, in Mendel’s name, wanted biology and society reorganized around the recognition that heredity is destiny. On the other side was the Oxford biologist W. F. R. Weldon, who, admiring Mendel's discoveries in a limited way, thought Bateson's "Mendelism" represented a backward step, since it pushed growing knowledge of the modifying role of environments, internal and external, to the margins. Weldon's untimely death in 1906, before he could finish a book setting out his alternative vision, is, Radick suggests, what sealed the Mendelian victory. Bringing together extensive archival research with searching analyses of the nature of science and history, Disputed Inheritance challenges the way we think about genetics and its possibilities, past, present, and future.

Heredity Produced
Author: Staffan Müller-Wille
Publisher: MIT Press
ISBN: 0262134764
Category : Heredity
Languages : en
Pages : 511
Book Description
The cultural history of heredity: scholars from a range of disciplines discuss the evolution of the concept of heredity, from the Early Modern understanding of the act of "generation" to its later nineteenth-century definition as the transmission of characteristics across generations. Until the middle of the eighteenth century, the biological makeup of an organism was ascribed to an individual instance of "generation"--involving conception, pregnancy, embryonic development, parturition, lactation, and even astral influences and maternal mood--rather than the biological transmission of traits and characteristics. Discussions of heredity and inheritance took place largely in the legal and political sphere. In Heredity Produced, scholars from a broad range of disciplines explore the development of the concept of heredity from the early modern period to the era of Darwin and Mendel. The contributors examine the evolution of the concept in disparate cultural realms--including law, medicine, and natural history--and show that it did not coalesce into a more general understanding of heredity until the mid-nineteenth century. They consider inheritance and kinship in a legal context; the classification of certain diseases as hereditary; the study of botany; animal and plant breeding and hybridization for desirable characteristics; theories of generation and evolution; and anthropology and its study of physical differences among humans, particularly skin color. The editors argue that only when people, animals, and plants became more mobile--and were separated from their natural habitats through exploration, colonialism, and other causes--could scientists distinguish between inherited and environmentally induced traits and develop a coherent theory of heredity. Contributors David Sabean, Silvia De Renzi, Ulrike Vedder, Carlos López Beltrán, Phillip K. Wilson, Laure Cartron, Staffan Müller-Wille, Marc J.
