Evolution: Components and Mechanisms introduces the many recent discoveries and insights that have added to the discipline of organic evolution, and combines them with the key topics needed to gain a fundamental understanding of the mechanisms of evolution. Each chapter covers an important topic or factor pertinent to a modern understanding of evolutionary theory, allowing easy access to particular topics for either study or review. Many chapters are cross-referenced. Modern evolutionary theory has expanded significantly within only the past two to three decades. In recent times the definition of a gene has evolved, the definition of organic evolution itself is in need of some modification, the number of known mechanisms of evolutionary change has increased dramatically, and the emphasis placed on opportunity and contingency has increased. This book synthesizes these changes and presents many of the novel topics in evolutionary theory in an accessible and thorough format. This book is an ideal, up-to-date resource for biologists, geneticists, evolutionary biologists, developmental biologists, and researchers in, as well as students and academics in these areas and professional scientists in many subfields of biology. Discusses many of the mechanisms responsible for evolutionary change Includes an appendix that provides a brief synopsis of these mechanisms with most discussed in greater detail in respective chapters Aids readers in their organization and understanding of the material by addressing the basic concepts and topics surrounding organic evolution Covers some topics not typically addressed, such as opportunity, contingency, symbiosis, and progress

This new textbook for students taking courses in evolution is addressed to one of the most difficult questions evolutionary biology, that of selection. Covering both artificial and natural selection, the author has written a short, readable text that will appeal to students and professionals alike. how the nature of the process determines the nature of evolutionary change.

Great progress has been made in our understanding of pollen-pistil interactions and self-incompatibility (SI) in flowering plants in the last few decades. This book covers a broad spectrum of research into SI, with accounts by internationally renowned scientists. It comprises two sections: Evolution and Population Genetics of SI, Molecular and Cell Biology of SI Systems. The reader will gain an insight into the diversity and complexity of these polymorphic cell-cell recognition and rejection systems. Heteromorphic and homomorphic SI systems and our current understanding of the evolution and phylogeny of these systems, based on the most recent molecular sequence data, are covered. Further, the book presents major advances in our knowledge of the pistil and pollen S-determinants and other unlinked components involved in SI, as well as the apparently diverse cellular regulatory mechanisms utilised to ensure inhibition of “self” pollen.

The Mechanisms Of Evolution

Do we understand how evolution works? In this book Steven Hawkins outlines various possible mechanisms of biological evolution - the Neo-Darwinian Modern Synthesis, Symbiogenesis and Developmental Systems Theory. He contrasts and compares these various theories and proposes a view of evolution in which all three mechanisms have a role to play. In this schema 'natural selection' only has a minor role to play in biological evolution. In the final chapter Hawkins considers non-biological evolution and is drawn to conclude that we are unable to understand the fundamental nature of both non-biological evolution and biological evolution.

Ecology and Evolution of Cancer is a timely work outlining ideas that not only represent a substantial and original contribution to the fields of evolution, ecology, and cancer, but also goes beyond by connecting the interfaces of these disciplines. This work engages the expertise of a multidisciplinary research team to collate and review the latest knowledge and developments in this exciting research field. The evolutionary perspective of cancer has gained significant international recognition and interest, which is fully understandable given that somatic cellular selection and evolution are elegant explanations for carcinogenesis. Cancer is now generally accepted to be an evolutionary and ecological process with complex interactions between tumor cells and their environment sharing many similarities with organismal evolution. As a critical contribution to this field of research the book is important and relevant for the applications of evolutionary biology to understand the origin of cancers, to control neoplastic progression, and to prevent therapeutic failures. Covers all aspects of the evolution of cancer, appealing to researchers seeking to understand its origins and effects of treatments on its progression, as well as to lecturers in evolutionary medicine Functions as both an introduction to cancer and evolution and a review of the current research on this burgeoning, exciting field, presented by an international group of leading editors and contributors Improves understanding of the origin and the evolution of cancer, aiding efforts to determine how this disease interferes with biotic interactions that govern ecosystems Highlights research that intends to apply evolutionary principles to help predict emergence and metastatic progression with the aim of improving therapies

Scientists studying the burning of stars, the evolution of species, DNA, the brain, the economy, and social change, all frequently describe their work as searching for mechanisms. Despite this fact, for much of the twentieth century philosophical discussions of the nature of mechanisms remained outside philosophy of science. The Routledge Handbook of Mechanisms and Mechanical Philosophy is an outstanding reference source to the key topics, problems, and debates in this exciting subject and is the first collection of its kind. Comprising over thirty chapters by a team of international contributors, the Handbook is divided into four Parts: Historical perspectives on mechanisms The nature of mechanisms Mechanisms and the philosophy of science Disciplinary perspectives on mechanisms. Within these Parts central topics and problems are examined, including the rise of mechanical philosophy in the seventeenth century; what mechanisms are made of and how they are organized; mechanisms and laws and regularities; how mechanisms are discovered and explained; dynamical systems theory; and disciplinary perspectives from physics, chemistry, biology, biomedicine, ecology, neuroscience, and the social sciences. Essential reading for students and researchers in philosophy of science, the Handbook will also be of interest to those in related fields, such as metaphysics, philosophy of psychology, and history of science.

An award-winning zoologist travels in Charles Darwin's footsteps, and in search of the meaning of life. In one of the most inhospitable places on Earth, zoologist Lloyd Spencer Davis comes face to face with an enraged leopard seal. Towering ice cliffs, a ferocious creature of the deep, and the extreme Antarctic environment all turn Davis's world view on its head. 'What the hell am I doing here?' This question sets Davis on a quest for insight and meaning in a world that still pitches theories of evolution against belief in a Creator; the science of natural selection against a faith that asserts our world was crafted by Intelligent Design. With a self-deprecating grin packed along with his cabin baggage - even when his passport isn't - Davis decides to follow the travels of the eminent nineteenth-century naturalist, Charles Darwin: the man who did more to change our understanding of this planet than any other biologist. Looking for Darwin gives us a personal and intimate insight into Darwin and what drove the man. It is also an attempt to resolve that initially panicked - and then far-reaching - question, that first hit Davis on the big ice. With a wealth of research and vivid imagery - along with a disarming honesty - Lloyd Spencer Davis takes the reader on an unforgettable world tour.
