What might be wrong with genetic accounts of personal or shared ancestry and origins? Genetic studies are often presented as valuable ways of understanding where we come from and how people are related. In Genetic Geographies, Catherine Nash pursues their troubling implications for our perception of sexual and national, as well as racial, difference. Bringing an incisive geographical focus to new genetic histories and genetic genealogy, Nash explores the making of ideas of genetic ancestry, indigeneity, and origins; the global human family, and commerce of ancestry in the United States and the United Kingdom, including the National Geographic Society's Geographic Society's Genographic Project and the People of the British Isles project. Tracing the tensions and contradictions between the emphasis on human genetic similarity and shared ancestry, and the attention given to distinctive patterns of relatedness and different ancestral origins, Nash challenges the assumption that the concepts of shared ancestry are necessarily progressive. Through sex, nation, and race, and its novel spatial lens. Genetic Geographies provides a timely critical guide to what happens when genetic science maps relatedness.

Population genetics has made great strides in applying statistical analysis and mathematical modeling to understand how genes mutate and spread through populations over time. But real populations also live in space. Streams, mountains, and other geographic features often divide populations, limit migration, or otherwise influence gene flow. This book rigorously examines the processes that determine geographic patterns of genetic variation, providing a comprehensive guide to their study and interpretation. Geographical Genetics has a unique focus on the mathematical relationships of spatial statistical measures of patterns to stochastic processes. It also develops the probability and distribution theory of various spatial statistics for analysis of population genetic data, detailing exact methods for using various spatial features to make precise inferences about migration, natural selection, and other dynamic forces. The book also reviews the experimental literature on the types of spatial patterns of genetic variation found within and among populations. And it makes an unprecedented strong connection between observed measures of spatial patterns and those predicted theoretically. Along the way, it introduces readers to the mathematics of spatial statistics, applications to specific population genetic systems, and the relationship between the mathematics of space-time processes and the formal theory of geographical genetics. Written by a leading authority, this is the first comprehensive treatment of geographical genetics. It is a much-needed guide to the theory, techniques, and applications of a field that will play an increasingly important role in population biology and ecology.

What might be wrong with genetic accounts of personal or shared ancestry and origins? Genetic studies are often presented as valuable ways of understanding where we come from and how people are related. In Genetic Geographies, Catherine Nash pursues their troubling implications for our perception of sexual and national, as well as racial, difference. Bringing an incisive geographical focus to bear on new genetic histories and genetic genealogy, Nash explores the making of ideas of genetic ancestry, indigeneity, and origins; the global human family; and national genetic heritage. In particular, she engages with the science, culture, and commerce of ancestry in the United States and the United Kingdom, including National Geographic’s Genographic Project and the People of the British Isles project. Tracing the tensions and contradictions between the emphasis on human genetic similarity and shared ancestry, and the attention given to distinctive patterns of relatedness and different ancestral origins, Nash challenges the assumption that the concepts of shared ancestry are necessarily progressive. She extends this scrutiny to claims about the “natural” differences between the sexes and the “nature” of reproduction in studies of the geography of human genetic variation. Through its focus on sex, nation, and race, and its novel spatial lens, Genetic Geographies provides a timely critical guide to what happens when genetic science maps relatedness.

Hailed as a breakthrough in the understanding of human evolution, The History and Geography of Human Genes offers the first full-scale reconstruction of where human populations originated and the paths by which they spread throughout the world. By mapping the worldwide geographic distribution of genes for over 110 traits in over 1800 primarily aboriginal populations, the authors charted migrations and devised a clock by which to date evolutionary history. This monumental work is now available in a more affordable paperback edition without the myriad illustrations and maps, but containing the full text and partial appendices of the authors' pathbreaking endeavor.

Introduces psychology and other social science students to the role genetics play in the individual differences in human behaviour.

This book provides a solid scientific basis for researchers, practitioners and students interested in the application of genetic principles to tropical forest ecology and management. It presents a concise overview of genetic variation, evolutionary processes and the human impact on forest genetic resources in the tropics. In addition, modern tools to assess genetic diversity patterns and the dynamics of genetic structures are introduced to the non-specialist reader.

This book explores how human population genetics has emerged as a means of imagining and enacting belonging in contemporary society. Venla Oikkonen approaches population genetics as an evolving set of technological, material, narrative and affective practices, arguing that these practices are engaged in multiple forms of belonging that are often mutually contradictory. Considering scientific, popular and fictional texts, with several carefully selected case studies spanning three decades, the author traces shifts in the affective, material and gendered preconditions of population genetic visions of belonging. Topics encompass the debate about Mitochondrial Eve, ancient human DNA, temporality and nostalgia, commercial genetic ancestry tests, and tensions between continental and national genetic inheritance. The book will be of particular interest to scholars and students of science and technology studies, cultural studies, sociology, and gender studies.

A provocative and timely case for how the science of genetics can help create a more just and equal society In recent years, scientists like Kathryn Paige Harden have shown that DNA makes us different, in our personalities and in our health—and in ways that matter for educational and economic success in our current society. In The Genetic Lottery, Harden introduces readers to the latest genetic science, dismantling dangerous ideas about racial superiority and challenging us to grapple with what equality really means in a world where people are born different. Weaving together personal stories with scientific evidence, Harden shows why our refusal to recognize the power of DNA perpetuates the myth of meritocracy, and argues that we must acknowledge the role of genetic luck if we are ever to create a fair society. Reclaiming genetic science from the legacy of eugenics, this groundbreaking book offers a bold new vision of society where everyone thrives, regardless of how one fares in the genetic lottery.

Over the past 20 years, public concerns have grown in response to the apparent rising prevalence of food allergy and related atopic conditions, such as eczema. Although evidence on the true prevalence of food allergy is complicated by insufficient or inconsistent data and studies with variable methodologies, many health care experts who care for patients agree that a real increase in food allergy has occurred and that it is unlikely to be due simply to an increase in awareness and better tools for diagnosis. Many stakeholders are concerned about these increases, including the general public, policy makers, regulatory agencies, the food industry, scientists, clinicians, and especially families of children and young people suffering from food allergy. At the present time, however, despite a mounting body of data on the prevalence, health consequences, and associated costs of food allergy, this chronic disease has not garnered the level of societal attention that it warrants. Moreover, for patients and families at risk, recommendations and guidelines have not been clear about preventing exposure or the onset of reactions or for managing this disease. Finding a Path to Safety in Food Allergy examines critical issues related to food allergy, including the prevalence and severity of food allergy and its impact on affected individuals, families, and communities; and current understanding of food allergy as a disease, and in diagnostics, treatments, prevention, and public policy. This report seeks to: clarify the nature of the disease, its causes, and its current management; highlight gaps in knowledge; encourage the implementation of management tools at many levels and among many stakeholders; and delineate a roadmap to safety for those who have, or are at risk of developing, food allergy, as well as for others in society who are responsible for public health.
