A reproduction of the forty-three articles that make up "The Genetics of Natural Populations" series, perhaps the most important single corpus in modern evolutionary genetics.

A discussion of the life and wok of Theodosius Dobzhansky and an assessment of the current research that has the origins in his findings and contributions.

The nature of populations, races, subspecies, and species. Genetic basis of isolation. Origin of isolation - theoretical. Origin of isolation - experimental. The nature of the speciation process.

Governments and researchers from industrial countries have been measuring science and technology for more than seventy years. This book provides an historical examination of official science and technology statistics and indicators in Western countries and addresses the following questions: What were the main historical moments that led to the development of statistics on science and technology? What were the main socio-political stakes behind the activities of science measurement? What were the philosophical and ideological conceptions that drove measurement? What statistics and indicators were developed and how were they constructed? The first part of the book concentrates on the construction and development of science and technology statistics from 1930 to the present, the principles at work, and the vested interests and forces behind that construction. The second part analyzes to what uses statistics were put, and with how much confidence actors used statistics to document their case or to promote their political agenda.

Describes the hypothesis that Darwin’s “natural selection,” reformulated by R.A. Fisher, J.B.S. Haldane, and S. Wright in the light of Mendelian genetics, is the exclusive mechanism for biological evolution. During the 1930s, alternatives such as Lamarchism, macromutations, and orthogenesis were rejected in favor of natural selection acting on small mutations, but there were disagreements about the role of random genetic drift in evolution. By the 1950s, research by T. Dobzhansky, E.B. Ford, and others persuaded leading evolutionists that natural selection was so powerful that drift was unimportant. This conclusion was accepted by most; however, some biology textbooks and popular articles mentioned drift in the late 1960s.

The Fourth Edition of Genetics of Populations is the most current, comprehensive, and accessible introduction to the field for advanced undergraduate and graduate students, and researchers in genetics, evolution, conservation, and related fields. In the past several years, interest in the application of population genetics principles to new molecular data has increased greatly, and Dr. Hedrick's new edition exemplifies his commitment to keeping pace with this dynamic area of study. Reorganized to allow students to focus more sharply on key material, the Fourth Edition integrates coverage of theoretical issues with a clear presentation of experimental population genetics and empirical data. Drawing examples from both recent and classic studies, and using a variety of organisms to illustrate the vast developments of population genetics, this text provides students and researchers with the most comprehensive resource in the field.
