This book is devoted to the collection, interpretation and analysis of population genetic data. Among the topics included here are studies on human evolutionary history, molecular techniques for generating data, statistical and computational techniques for the interpretation of such data, and stochastic models for genealogy and population structure. The chapters reflect the close interaction between experimental molecular biologists and theoreticians. The book will be useful for specialists in the area, as well as mathematicians, statisticians, computer scientists and biologists wanting a brief overview of current problems in the field.

Population genetics is the study of the allele frequency distribution and change under the influence of the four evolutionary forces: natural selection, genetic drift, mutation and gene flow. It also takes account of population subdivision and population structure in space. This book presents the latest research in the field from around the globe.
Around 60,000 years ago, a man, genetically identical to us, lived in Africa. Every person alive today is descended from him. How did this real-life Adam wind up as the father of us all? What happened to the descendants of other men who lived at the same time? And why, if modern humans share a single prehistoric ancestor, do we come in so many sizes, shapes, and races? Examining the hidden secrets of human evolution in our genetic code, the author reveals how developments in the revolutionary science of population genetics have made it possible to create a family tree for the whole of humanity. Replete with marvelous anecdotes and remarkable information, from the truth about the real Adam and Eve to the way differing racial types emerged, this book is an enthralling, epic tour through the history and development of early humankind.
This volume examines the interrelationship of ecology, subsistence pat terns, and the observed genetic variation in human populations. Hence, the book is divided conceptually into the following categories: nonhuman primates, hunters and gatherers, nomads, swidden agriculturalists, peas ant farmers, religious isolates, and modern and urban aggregates. While many of these populations have experienced (and are experiencing) ac culturation as a result of contact with technologically more advanced groups, the genetic structures described in this volume attempt to recon struct the traditional patterns as well as genetic changes because of con tact. Most chapters also integrate biological (genetic), social, and de mographic data within an ecological frame thus presenting a holistic view of the population structures of ecologically distinct groups. The first chapter examines the body of early nonhuman primate lit erature that emphasized ecological determinism in effecting the popula tion structure of our primate ancestors-relatives. It also examines more recent literature (since 1970) in which it became apparent that greater flexibility exists in primate social structure within specific environmental frameworks. Thus, it appears that our nonhuman primate evolutionary heritage is not one of ecological determinism in social organization but one of flexibility and rapid change suggesting the evolutionary success of our species is based upon a system of flexibility and that social ad aptations can be accomplished in a number of diverse ways.
"Adaptive biological diversification occurs when frequency-dependent selection generates advantages for rare phenotypes and induces a split of an ancestral lineage into multiple descendant lineages. Using adaptive dynamics theory, individual-based simulations, and partial differential equation models, this book illustrates that adaptive diversification due to frequency-dependent ecological interaction is a theoretically ubiquitous phenomenon"--Provided by publisher.
This volume not only offers an intellectual biography of one of the most important biologists and social thinkers of the twentieth century but also illuminates the development of evolutionary studies in Russia and in the West. Theodosius Dobzhansky (1900-1975), a creator of the "evolutionary synthesis" and the author of its first modern statement, Genetics and the Origin of Species (1937), founded modern Western population genetics and wrote many popular books on such topics as human evolution, race and racism, equality, and human destiny. In this, the first book devoted to an analysis of the historical, scientific, and cultural dimensions of Dobzhansky's life and thought, an international group of historians, biologists, and philosophers addresses the full span of his career in Russia and the United States. Beginning with the reminiscences of his daughter, Sophia Dobzhansky Coe, these essays cover Dobzhansky's Russian roots (Nikolai L. Krementsov, Daniel A. Alexandrov, Mikhail B. Konashev), the Morgan Lab (Garland E. Allen, William B. Provine, Robert E. Kohler, Richard M. Burian), his scientific legacy (Scott F. Gilbert, Bruce Wallace, Charles E. Taylor), and his social, political, philosophical, and religious thought (Costas B. Krimbas, John Beatty, Diane B. Paul, Michael Ruse). Originally published in 1994. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
This textbook shows readers how models of the genetic processes involved in evolution are made (including natural selection, migration, mutation, and genetic drift in finite populations), and how the models are used to interpret classical and molecular genetic data. The material is intended for advanced level undergraduate courses in genetics and evolutionary biology, graduate students in evolutionary biology and human genetics, and researchers in related fields who wish to learn evolutionary genetics. The topics covered include genetic variation, DNA sequence variability and its measurement, the different types of natural selection and their effects (e.g. the maintenance of variation, directional selection, and adaptation), the interactions between selection and mutation or migration, the description and analysis of variation at multiple sites in the genome, genetic drift, and the effects of spatial structure.
This volume presents a review of metapopulation biology. It describes key theories of study and applies the best field studies to the conservation of species in fragmented landscapes. The work explains and critically assess the value of the metapopulation concept for field studies and conservation.
