Book Description
This study reproduces one "Report of Meetings" & six "Bulletins" from the Committee on Common Problems of Genetics, Paleontology, & Systematics. This Committee operated as an administrative unit of the National Research Council, part of the U.S. Nat. Acad. of Science. It was launched in 1943, blossomed for two years, then served as a cornerstone for other cooperative projects. The Committee provided a crucial foothold for those seeking a synthetics view of evolution in 1940s America. These forgotten documents show the Committee at work: building coalitions, defining priorities, & negotiating a common vision. They also show factions within the Committee competing for the leadership of this emerging community. Photo.

Book Description
One of the privileges of appointment to a Chair at another University is that it gives one the right to talk to many distinguished people about their work and ideas. E. B. Ford was known to me before I came to Oxford as the author of a book on butterflies and as somewhat of an eccentric, but I was quite unprepared for the welcome he gave me into the Department of Zoology and for the enormous interest of the subject which he gradually revealed to me. My contact with the Genetics Laboratory was made easier by one of the first things I had to do. Within a few weeks of my arrival, it came to light that a new building for another department was to be erected on a piece of land, known to us as 'Henry's weed garden' but generally regarded as being derelict. Even my, at that time, elementary, knowledge of ecological genetics made it easy to realize that the population of caterpillars that had been under continuous observation there for eleven years put it in a rather special category of wilderness; although I did not succeed in saving it, I was able to persuade the university to substitute another experimental plot and this may have helped the geneticists to appreciate that the new professor was not only interested in electrical apparatus.

Book Description
The common fruitfly, Drosophila, is the most extensively studied of all organisms in genetical research. Thus, it would appear to be the best model for achieving new insights. Its use in evolutionary studies has resulted in an explosion of knowledge which has never before been gathered into a single volume. This book spans the full range of evolutionary studies - population genetics, ecology, ecological genetics, speciation, phylogenetics, genome evolution, molecular; evolution, and development. In covering these topics, highlights of empirical research are emphasized and are put into the context of major issues in evolution.

Book Description
Inversion polymorphism in Drosophila has long served as a research subject for a variety of evolutionary studies and continues to be extremely important in understanding evolutionary principles today. Until now, no single volume has ever been assembled as a summary of this work. Drosophila Inversion Polymorphism provides background information, explores new and rigorous approaches to reconstructing phylogenetic relationships from inversion variation, and discusses inversion polymorphism in the six most studied species groups. Some chapters examine general principles and conclusions, some present detailed data sets (many of which have never before been published), and others offer detailed chromosome maps for identification. The book is a one-of-a-kind source of summary discussions and data ripe for analysis. Geneticists, evolutionary biologists, biologists, and all investigators researching inversion polymorphisms should consider Drosophila Inversion Polymorphism a "must-have" volume.

Book Description
This book introduces readers to classical population genetics and the ways in which it can be applied to practical problems, including testing for natural selection, genetic drift, genetic differentiation, population structuring, gene flow and linkage disequilibrium. It provides a comprehensive monograph on the topic, addressing the theory, applications and evolutionary deductions, which are clearly explained using experimental results. It also offers separate chapters on origin, establishment and spread of chromosomal aberrations in populations along with details of culturing, maintaining and using Drosophila ananassae (genetically unique and the most commonly used species along with D. melanogaster) for genetic research. Encompassing topics like genetics, evolution, Drosophila genetics, population genetics, population structuring, natural selection and genetic drift in considerable detail, it provides a valuable resource to undergraduate and postgraduate students, as well as researchers at all level. This book explores some fundamental questions concerning the role of natural selection and genetic drift on the degree of inversion polymorphism. India, with its wide diversity in geo-climatic conditions, provides an excellent platform to conduct such studies. The book showcases sampling records of inversion frequencies in natural Indian populations of D. ananassae that cover more than two decades. It highlights case studies in which sampling data on inversion frequencies was combined with that from earlier surveys, generating a time series that allows the evolutionary dynamics of inversion polymorphism to be explored. Such long time series are rare but nonetheless crucial for studying the evolutionary dynamics of inversion polymorphism. The population-genetic analysis discussed is unprecedented in terms of its temporal (two decades) and spatial (most regions of India covered) scale and investigates the patterns of polymorphic system in D. ananassae to see if there is any temporal divergence. It endeavors to present a holistic picture of inversion polymorphism across the country (India). Chromosomal aberrations, particularly paracentric inversions, are used as a tool for discussing population genetic studies, helping human geneticists, gynecologists and other medical professionals understand why some aberrations are fatal in humans, with affected embryos often not surviving the first trimester of pregnancy, while similar aberrations in Drosophila flies aid in their adaptation to the environmental heterogeneity across the globe.

Book Description
With the rise of genomics, the life sciences have entered a new era. This book provides a comprehensive history of mapping procedures as they were developed in classical genetics. An accompanying volume - From Molecular Genetics to Genomics - covers the history of molecular genetics and genomics. The book shows that the technology of genetic mapping is by no means a recent acquisition of molecular genetics or even genetic engineering. It demonstrates that the development of mapping technologies has accompanied the rise of modern genetics from its very beginnings. In Section One, Mendelian genetics is set in perspective from the viewpoint of the detection and description of linkage phenomena. Section Two addresses the role of mapping for the experimental working practice of classical geneticists, their social interactions and for the laboratory 'life worlds'. With detailed analyses of the scientific practices of mapping and its illustration of the diversity of mapping practices this book is a significant contibution to the history of genetics. A companion volume from the same editors - From Molecular Genetics to Genomics: The Mapping Cultures of Twentieth Century Genetics - covers the history of molecular genetics and genomics.
