The transition in anthropological and biomedical research methods over the past 50 years, from anthropometric and craniometric measurements to large-scale microarray genetic studies has resulted in continued revision of opinions and ideas relating to the factors and forces that drive human variation. Human Variation:From the Laboratory to the Field brings together the contributions of 22 scientists working in four continents to identify and address challenges imposed by variability. It reviews the way we examine and analyze human variation, paying specific attention to genetics, growth and development, and physiology. In presenting new evidence and findings, it also discusses current developments in methodology and analytical techniques, detailing both field and laboratory approaches, and looking at how the two perspectives complement each other. In bridging that gap between laboratory trials and studies of the human in context, this book covers a number of interesting research areas including - Human adaptation to natural and artificial light, including variations in circadian photosensitivity and effects of light on GI activity Cold tolerance and lifestyle in modern society Genetics of body weight and obesity Human adaptability to emotional and intellectual mental stresses Geography, migration, climate, and environmental plasticity as contributors to human variation Impact of natural environmental stressors including pollution on physiological and morphological processes This book is the latest volume in a series of works from the Society for the Study of Human Biology (SSHB), which for half a century has advanced and promoted research in the biology of human populations in all of its branches including human viability, genetics, human adaptability, and ecology, and evolution. It holds two scientific meetings a year. This volume represents work presented during its most recent gathering.

In the space of one generation major changes have begun to take place in the field of human reproduction. A rapid increase in the control of fertility and the understanding and treatment of sexual health issues have been accompanied by an emerging threat to reproductive function linked to increasing environmental pollution and dramatic changes in lifestyle. Organised around four key themes, this book provides a valuable review of some of the most important recent findings in human reproductive ecology. Major topics include the impact of the environment on reproduction, the role of physical activity and energetics in regulating reproduction, sexual maturation and ovulation assessment and demographic, health and family planning issues. Both theoretical and practical issues are covered, including the evolution and importance of the menopause and the various statistical methods by which researchers can analyse characteristics of the menstrual cycle in field studies.

In past years considerable interest has been focused on migration as an important cause of change in the genetic and demographic structure of human populations. This book synthesises the biological consequences of changes environments on the migrants and the genetic impact of immigration on the host populations. Patterns of migration, past and present and genetic, epidemological and demographic consequences are considered, forming a unique synthesis for human biologists in general. Individual chapters deal with the peopling of the continents, migration in the recent past, the effects of gene flow and rural to urban migration. In addition, a detailed analysis of the relationship between migration, adaptation and disease is presented. Advanced students and research workers in a wide variety of disciplines, including population genetics, demography, anthropology and social geography will find this book particularly valuable in relating their own special interests to other biological aspects of human migration.

As we enter the twenty-first century, a number of medical, environmental, and social changes have profoundly affected human reproduction. This book discusses some of the more dramatic changes in an accessible manner, illustrating the ways in which human biology and culture can affect fertility. It provides a unique interdisciplinary perspective on the subject. Topics of discussion include medical technological advances that equip us with potential cures for many causes of infertility; diseases, such as AIDS, that have a devastating impact on the reproductive and social lives of humans; increasing industrialization and the development of fabricated materials that pollute our environment in unforeseen ways with possibly devastating effects on human health and fertility; and social revolutions that profoundly alter human relationships, such as nonmarital unions between heterosexual couples, same-sex relationships, and adoption and surrogacy.

Considerable attention is being paid to the use of molecular evidence in studies of human diversity and origins. Much of the early work was based on evidence from mitochondrial DNA, but this has been supplemented by important information from nuclear DNA from both the Y chromosomes and the autosomes. The bulk of the material available is also from living populations, but this is being extended by the study of DNA from archaic populations. The underlying models used in interpreting this evidence are developments of the neutral theory of molecular evolution, but also consider the possible role of selection. This 1996 volume brings together evidence from an international group of research workers. It will be an important reference for researchers in human biology, molecular biology and genetics alike.

Plasticity refers to the ability of many organisms to change their biology or behavior to respond to changes in the environment. Humans are probably the most plastic of all species, and hence the most variable. This is the first book to examine the history of research in this area and it provides information on state-of-the-art research methods and discoveries. It also maps out some areas of future research in human plasticity and variability. Topics discussed include child growth, starvation, diseases of both young and old, and the effects of migration, modernization and other life-style changes. The book will be especially useful to biological anthropologists, human biologists and medical scientists interested in knowing more about how and why humans vary.

It is widely believed that reproductive cycles are very similar between human females. However, there are in fact considerable variations both between individuals and within the reproductive life of any given individual. 'Normal' reproductive cycles cover a wide range of eventualities, and the likelihood of successful monthly egg release and ensuing pregnancy can be modified by a large number of factors. In this book, the variability of human fertility is examined by first looking at the physiological processes regulating reproduction, and the roles of metabolic adaptation and metabolic load. Inter-population variation in normal ovarian function is then discussed, covering the importance of factors such as age, disease and breastfeeding in modifying ovarian function. First published in 1996, this is an important book for all those interested in human fertility.

This book is about doing research, not about the results obtained. Those engaged on their first research may have had plenty of preparation about the techniques and results of prior research related to their proposed study, but may have limited knowledge of the actual strategies employed or pitfalls encountered by others who have conducted successful field and survey studies. In this book, a number of researchers with experience of working on problems including environmental stresses, population genetics, parasitic vectors and vital records describe obstacles encountered and successful strategies used in their own studies and in those of others. One learns to do research by trial and error, but accounts by experienced investigators can supplement what one learns from mentors and fellow students.

Anthropometry is the measurement of human morphology and is used in a wide range of applied and research contexts. In this volume, distinguished contributors including anthropologists, human biologists, physiologists, nutritionists and clinical scientists describe many of the ways in which anthropometry is used, and discuss problems associated with different methods of assessment. Topics include the measurement of growth asymmetry and variability in adult body size, measurement error and statistical issues in anthropometry and the construction and use of growth charts in growth monitoring. In addition, the use of anthropometry in assessments of body composition, physical performance and fitness is discussed. This book will be of interest to graduates and researchers in human biology, anthropology and nutrition. It will also be useful to workers in sports medicine, ergonomics, orthopaedics and paediatrics.

The unique contribution made by biological anthropology to human welfare lies in the fundamental understanding it can provide of the dynamic interrelationships between physical and social factors. By understanding these patterns, we can interpret the significance of variation in such measures of human well-being in terms of the incidence of disease and mortality rates. Topics covered in this book include reproductive ecology and fertility, nutritional status in relation to health, and the effects of pollution on individual growth. In later chapters, the concepts of physiological adaptation and Darwinian fitness and their relation to individual physical fitness are explored.

Disease is an ever-present threat faced by all human societies. Today, this concept has become an influential area of study known as the global burden of disease, which encompasses contemporary health concerns such as the economic costs of disease, the societal impact of illness in developing nations, and infectious diseases resulting from lifestyle exposures. Before we can ease this global burden, it is essential to establish an accurate view of the current status of human health and disease around the world. Addressing key areas that reflect our understanding of disease, The Changing Face of Disease: Implications for Society explores the evolution of disease, the implications for human societies, its ecology, and the current human response. This volume aims to broaden our view of disease at the dawn of the 21st century through topics such as epidemiological transition, mathematical modeling of disease evolution, parasitic disease, urban pollution and illness, and under-nutrition and obesity. Contributions to the text reflect the authors' diverse perspectives and studies on human population biology, biological anthropology, and biomedical and public health issues. This authoritative volume traces the evolution of modern disease and explores contemporary health challenges resulting from genetic, environmental, economic, and lifestyle factors. Through many levels of analysis, it provides a clear picture of the present state of health and disease and reminds us of the global burdens that have yet to be remedied.
