This book presents coverage of the principles and practice of molecular clocks, which have provided fascinating and unprecedented insights into the evolutionary timescale of life on earth. It begins by following the early development of the molecular evolutionary clock in the 1960s, and leads to the complex statistical approaches that are now used to analyse genome sequences. The chapters of this book have been contributed by leading experts in the field and address the important issues of evolutionary rates, molecular dating, and phylogenomic analysis. This is the first time that these different aspects of the molecular clock have been brought together in a single, comprehensive volume. It is an invaluable reference for students and researchers interested in evolutionary biology, genetic analysis, and genomic evolution.

Determining the precise timing for the evolutionary origin of groups of organisms has become increasingly important as scientists from diverse disciplines attempt to examine rates of anatomical or molecular evolution and correlate intrinsic biological events to extrinsic environmental events. Molecular clock analyses indicate that many major groups

This volume in the Monographs in Evolutionary Biology series addresses issues that are part of an emerging area of research loosely called "mo lecular evolution. " Its practitioners include both molecular biologists cu rious about the evolutionary implications of their data and evolutionary biologists pushing their analyses to the molecular level. The union of these fields of molecular and organismal biology has been turbulent at times, and, as shall be seen, this dialectic has led to some very serious challenges to long-held notions about the role of natural selection in evolution and the economy of genome organization in eukaryotes. As an inevitable outgrowth of molecular biology, molecular evolution is necessarily a young discipline, but it can already point proudly to two major discoveries. The first, is the molecular clock, a concept that has emerged from the analysis of at least four data sets-amino acid sequences, immunologic data, DNA renaturation studies, and, recently, analyses of DNA sequences. The reality of a strong stochastic component in the evolution of nucleotide sequences can no longer be doubted, although the accuracy of the clock with regard to particular sequences and within particular groups of or ganisms should be independently measured each time it is used. Never theless, molecular clocks will assume increasingly important roles in phy logenetic reconstructions, especially since the fossil record is so fragmentary. The second major discovery of molecular evolution has been the incredible complexity of the eukaryotic genome.

This book is about the rate of molecular evolution in mammals. Various methods of comparative analysis have been applied to different kinds of molecular data in attempts to resolve the issue. The choice of molecular data, and more importantly, the different assumptions made in the analysis have resulted in contrasting conclusions being drawn. These assumptions are critically evaluated and draw the conclusion that for "silent" DNA the molecular clock hypothesis cannot be rejected. For amino acids the clock hypothesis is rejected and this appears to reflect the action of natural selection. The implications of the DNA clock in relation to the pattern of mammalian evolution and the process of mutation are discussed.

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.

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.

Evolutionary Processes and Theory contains the proceedings of a workshop held in Israel in March 1985. Contributors explore evolutionary processes and theory and highlight advances in knowledge concerning differentiation, metabolic and immunological mechanisms, and the molecular biology of the genome. Issues that are being debated are also considered, including the origin and evolution of sexual systems, the genetics of altruism, and general forms and levels of social evolution. This volume is organized into six sections encompassing 33 chapters and begins with an overview of the evolutionary problems of molecular biology. Some chapters are devoted to topics such as the role of gene regulation in evolutionary processes; the structural diversity and evolution of intermediate filament proteins; and adaptation and evolution in the immune system. The next section examines the tempo and mode of molecular evolution, including that of hybrid dysgenesis systems, as well as the statistical aspects of the molecular clock. Later chapters focus on DNA and protein sequences; sexual selection and speciation; and the relation between speciation mechanisms and macroevolutionary patterns. The book also methodically explains population genetics, with particular reference to the altruistic behavior in sibling groups with unrelated intruders, the endosperm evolution in higher plants, and the evolutionary aspects of sexual reproduction in predominantly asexual populations. This book will be of interest to geneticists and molecular biologists.

Plant molecular biology has produced an ever-increasing flood of data about genes and genomes. Evolutionary biology and systematics provides the context for synthesizing this information. This book brings together contributions from evolutionary biologists, systematists, developmental geneticists, biochemists, and others working on diverse aspects of plant biology whose work touches to varying degrees on plant molecular evolution. The book is organized in three parts, the first of which introduces broad topics in evolutionary biology and summarizes advances in plant molecular phylogenetics, with emphasis on model plant systems. The second segment presents a series of case studies of gene family evolution, while the third gives overviews of the evolution of important plant processes such as disease resistance, nodulation, hybridization, transposable elements and genome evolution, and polyploidy.
