Human Heredity In The Twentieth Century

The essays in this collection examine how human heredity was understood between the end of the First World War and the early 1970s. The contributors explore the interaction of science, medicine and society in determining how heredity was viewed across the world during the politically turbulent years of the twentieth century.

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.

Evolutionary selection has been radically relaxed in the human species as a result of the development of civilization, science in general, and medicine in particular. While these advances have hugely benefited current populations, they have to a significant degree released the species from the biological process which created it and maintains its viability. Formerly, natural selection took place largely as a result of differential mortality, but now that most people survive well beyond their child bearing years, selection is determined largely by differential fertility. Aside from genetic illnesses, this new selection is also characterized by a negative correlation between fertility and intelligencethe core of eugenic concern for over a century. Eugenics views itself as the fourth leg of the chair of civilization, the other three being a) a thrifty expenditure of natural resources, b) mitigation of environmental pollution, and c) maintenance of a human population not exceeding the planets carrying capacity. Eugenics, which can be thought of as human ecology, is thus part and parcel of the environmental movement. Humanity is defined, not as the totality of the currently living population, but as the number of people who will potentially ever live. This is a book about the struggle for human rights and parental responsibility.

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.

Written by 30 authors from all over the world, this book provides a unique overview of exciting discoveries and surprising developments in human genetics over the last 50 years. The individual contributions, based on seven international workshops on the history of human genetics, cover a diverse range of topics, including the early years of the discipline, gene mapping and diagnostics. Further, they discuss the status quo of human genetics in different countries and highlight the value of genetic counseling as an important subfield of medical genetics.

The Meanings of the Gene is a compelling look at societal hopes and fears about genetics in the course of the twentieth century. The work of scientists and doctors in advancing genetic research and its applications has been accompanied by plenty of discussion in the popular press—from Good Housekeeping and Forbes to Ms. and the Congressional Record—about such topics as eugenics, sterilization, DNA, genetic counseling, and sex selection. By demonstrating the role of rhetoric and ideology in public discussions about genetics, Condit raises the controversial question, Who shapes decisions about genetic research and its consequences for humans—scientists, or the public? Analyzing hundreds of stories from American magazines—and, later, television news—from the 1910s to the 1990s, Condit identifies three central and enduring public worries about genetics: that genes are deterministic arbiters of human fate; that genetics research can be used for discriminatory ends; and that advances in genetics encourage perfectionistic thinking about our children. Other key public concerns that Condit highlights are the complexity of genetic decision-making and potential for invasion of privacy; conflict over the human genetic code and experimentation with DNA; and family genetics and reproductive decisions. Her analysis reveals a persistent debate in the popular media between themes of genetic determinism (such as eugenics) and more egalitarian views that place genes within the complexity of biological and social life. The Meanings of the Gene offers an insightful view of our continuing efforts to grapple with our biological natures and to define what it means, and will mean in the future, to be human.

"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.
