Book Description
This book focuses on drosophila as an especially useful model organism for exploring questions of evolutionary biology in the full range of evolutionary studies: population genetics, ecology, ecological genetics, speciation, phylogenetics, genome evolution, molecular evolution, and development. The author presents an integrated view of evolutionary biology as elucidated in this single organism. Special effort is made to point out holes in our knowledge and areas particularly ripe for new investigation.

Book Description
The study of evolution at the molecular level has given the subject of evolutionary biology a new significance. Phylogenetic 'trees' of gene sequences are a powerful tool for recovering evolutionary relationships among species, and can be used to answer a broad range of evolutionary and ecological questions. They are also beginning to permeate the medical sciences. In this book, the authors approach the study of molecular evolution with the phylogenetic tree as a central metaphor. This will equip students and professionals with the ability to see both the evolutionary relevance of molecular data, and the significance evolutionary theory has for molecular studies. The book is accessible yet sufficiently detailed and explicit so that the student can learn the mechanics of the procedures discussed. The book is intended for senior undergraduate and graduate students taking courses in molecular evolution/phylogenetic reconstruction. It will also be a useful supplement for students taking wider courses in evolution, as well as a valuable resource for professionals. First student textbook of phylogenetic reconstruction which uses the tree as a central metaphor of evolution. Chapter summaries and annotated suggestions for further reading. Worked examples facilitate understanding of some of the more complex issues. Emphasis on clarity and accessibility.

Book Description
Methuselah Flies presents a trailblazing project on the biology of aging. It describes research on the first organisms to have their lifespan increased, and their aging slowed, by hereditary manipulation. These organisms are fruit flies from the species Drosophila melanogaster, the great workhorse of genetics. Michael Rose and his colleagues have been able to double the lifespan of these insects, and improved their health in numerous respects as well. The study of these flies with postponed aging is one of the best means we have of understanding, and ultimately achieving, the postponement of aging in humans. As such, the carefully presented detail of this book will be of value to research devoted to the understanding and control of aging.Methuselah Flies: ? is a tightly edited distillation of twenty years of work by many scientists? contains the original publications regarding the longer-lived fruit flies? offers commentaries on each of the topics covered ? new, short essays that put the individual research papers in a wider context? gives full access to the original data ? captures the scientific significance of postponed aging for a wide academic audienc

Book Description
This work provides a unified theory that addresses the important problem of the origin and maintenance of genetic variation in natural populations. With modern molecular techniques, variation is found in all species, sometimes at astonishingly high levels. Yet, despite these observations, the forces that maintain variation within and between species have been difficult subjects of study. Because they act very weakly and operate over vast time scales, scientists must rely on indirect inferences and speculative mathematical models. However, despite these obstacles, many advances have been made. The author's research in molecular genetics, evolution, and bio-mathematics has enabled him to draw on this work, and present a coherent and valuable view of the field. The book is divided into three parts. The first consists of three chapters on protein evolution, DNA evolution, and molecular mechanisms. This section reviews the experimental observations on genetic variation. The second part gives a unified treatment of the mathematical theory of selection in a fluctuating environment. The final two chapters combine the earlier assessments in a treatment of the scientific status of two competing theories for the maintenance of genetic variation. Steeped in the enormous advances population genetics has made over the past 25 years, this book has proven highly popular among human geneticists, biologists, evolutionary theorists, and bio-mathematicians.

Book Description
Motoo Kimura, as founder of the neutral theory, is uniquely placed to write this book. He first proposed the theory in 1968 to explain the unexpectedly high rate of evolutionary change and very large amount of intraspecific variability at the molecular level that had been uncovered by new techniques in molecular biology. The theory - which asserts that the great majority of evolutionary changes at the molecular level are caused not by Darwinian selection but by random drift of selectively neutral mutants - has caused controversy ever since. This book is the first comprehensive treatment of this subject and the author synthesises a wealth of material - ranging from a historical perspective, through recent molecular discoveries, to sophisticated mathematical arguments - all presented in a most lucid manner.

Book Description
Biology of Drosophila was first published by John Wiley and Sons in 1950. Until its appearance, no central, synthesized source of biological data on Drosophila melanogaster was available, despite the fly's importance to science for three decades. Ten years in the making, it was an immediate success and remained in print for two decades. However, original copies are now very hard to find. This facsimile edition makes available to the fly community once again its most enduring work of reference.

Book Description
Ecological and evolutionary genetics span many disciplines and virtually all levels of biological investigation, from the genetic information itself to the principles governing the complex organization of living things. The ideas and informa tion generated by ecological and evolutionary genetics provide the substance for strong inferences on the origins, changes and patterns of structural and functional organization in bio logical communi ties. It is the coordination of these ideas and thoughts that will provide the answers to many fundamental questions in biology. There is no doubt that Drosophilids provide strong model systems amenable to experimental manipulation and useful for testing pertinent hypotheses in ecological and evolutionary genetics. The chapters in this volume represent efforts to use Drosophila species for such a purpose. The volume consists of a dedication to William B. Heed, followed by four major sections: Ecological Genetics, Habitat Selection, Biochemical Genetics and Molecular Evolution. Each section is introduced by a short statement, and each chapter has an independent summary. The chapters contain the sub stance of talks given at a joint Australia-US workshop held January 5-10, 1989 at the University of New England, New South Wales, Australia. We are indebted to the Division of International Programs of the National Science Foundation (USA) and to the Science and Technology Collaboration Section of the Department of Industry, Technology and Commerce (Australia) for the provi sion of financial support under the US/Australia Science and Technology Agreement.
