The function of vertebrate hearing is served by a surprising variety of sensory structures in the different groups of fish, amphibians, reptiles, birds, and mammals. This book discusses the origin, specialization, and functional properties of sensory hair cells, beginning with environmental constraints on acoustic systems and addressing in detail the evolutionary history behind modern structure and function in the vertebrate ear. Taking a comparative approach, chapters are devoted to each of the vertebrate groups, outlining the transition to land existence and the further parallel and independent adaptations of amniotic groups living in air. The volume explores in depth the specific properties of hair cells that allowed them to become sensitive to sound and capable of analyzing sounds into their respective frequency components. Evolution of the Vertebrate Auditory System is directed to a broad audience of biologists and clinicians, from the level of advanced undergraduate students to professionals interested in learning more about the evolution, structure, and function of the ear.

In this new fourth edition, Campbell has revised and updated his classic introduction to the field. Human Evolution synthesizes the major findings of modern research and theory and presents a complete and integrated account of the evolution of human beings. New developments in microbiology and recent fossil records are incorporated into the enormous range of this volume, with the resulting text as lucid and comprehensive as earlier editions. The fourth edition retains the thematic structure and organization of the third, with its cogent treatment of human variability and speciation, primate locomotion, and nonverbal communication and the evolution of language, supported by more than 150 detailed illustrations and an expanded and updated glossary and bibliography. As in prior editions, the book treats evolution as a concomitant development of the main behavioral and functional complexes of the genus Homo among them motor control and locomotion, mastication and digestion, the senses and reproduction. It analyzes each complex in terms of its changing function, and continually stresses how the separate complexes evolve interdependently over the long course of the human journey. All these aspects are placed within the context of contemporary evolutionary and genetic theory, analyses of the varied extensions of the fossil record, and contemporary primatology and comparative morphology. The result is a primary text for undergraduate and graduate courses, one that will also serve as required reading for anthropologists, biologists, and nonspecialists with an interest in human evolution. "Synthesizes the conventional academic thought into a textbook or detailed account for lay readers. Along the chronological narrative are discussions of progress in homeostasis, the primate radiation, locomotion and the hindlimb, function and structure of the head, reproduction and social structure, and culture and society." Book News Bernard Campbell has been a visiting lecturer at Harvard and Cambridge, and has taught and conducted research in Eastern and Southern Africa. He was professor of anthropology at the University of California, Los Angeles, from 1970-76. Dr. Campbell is author/coauthor of Sexual Selection and the Descent of Man; Human Ecology (second edition, Aldine); Humankind Emerging and the definitive three-volume Catalogue of Fossil Hominids.

Most organisms and populations have to cope with hostile environments, threatening their existence. Their ability to respond phenotypically and genetically to these challenges and to evolve adaptive mechanisms is, therefore, crucial. The contributions to this book aim at understanding, from a evolutionary perspective, the impact of stress on biological systems. Scientists, applying different approaches spanning from the molecular and the protein level to individuals, populations and ecosystems, explore how organisms adapt to extreme environments, how stress changes genetic structure and affects life histories, how organisms cope with thermal stress through acclimation, and how environmental and genetic stress induce fluctuating asymmetry, shape selection pressure and cause extinction of populations. Finally, it discusses the role of stress in evolutionary change, from stress induced mutations and selection to speciation and evolution at the geological time scale. The book contains reviews and novel scientific results on the subject. It will be of interest to both researchers and graduate students and may serve as a text for graduate courses.

What is it that makes us human? This is one of the most challenging and important questions we face. Our species' defining characteristic is language - we appear to be unique in the natural world in having such an incredibly open-ended system for putting thoughts into words. If we are to truly understand ourselves as a species we must understand the origins of this strange and unique ability. To do so, we need to answer some of the most intriguing questions in contemporary scientific research: Where did language come from? How did it evolve? Why are we unique in possessing it? This book, for the first time, brings together the leading thinkers who are trying to unlock the puzzle of language evolution. Here we see the latest ideas and theories from fields as diverse as anthropology, archaeology, artificial life, biology, cognitive science, linguistics, neuroscience, and psychology. In a series of seventeen well-written and accessible chapters we get an unrivalled view of the state of the art in this exciting area. Current controversies are revealed and new perspectives uncovered, in a clear and readable guide to the latest theories. This collection marks a major step forward in our quest to understand the origins and evolution of human language. In doing so it sheds new light on the process of evolution, the workings of the brain, the structure of language, and - most importantly - what it means to be human. Language Evolution is essential reading for researchers and students working in the areas covered, and has been used as a textbook for courses in the field. It will also attract the general reader who wants to know more about this fascinating subject.

Differential evolution is arguably one of the hottest topics in today's computational intelligence research. This book seeks to present a comprehensive study of the state of the art in this technology and also directions for future research. The fourteen chapters of this book have been written by leading experts in the area. The first seven chapters focus on algorithm design, while the last seven describe real-world applications. Chapter 1 introduces the basic differential evolution (DE) algorithm and presents a broad overview of the field. Chapter 2 presents a new, rotationally invariant DE algorithm. The role of self-adaptive control parameters in DE is investigated in Chapter 3. Chapters 4 and 5 address constrained optimization; the former develops suitable stopping conditions for the DE run, and the latter presents an improved DE algorithm for problems with very small feasible regions. A novel DE algorithm, based on the concept of "opposite" points, is the topic of Chapter 6. Chapter 7 provides a survey of multi-objective differential evolution algorithms. A review of the major application areas of differential evolution is presented in Chapter 8. Chapter 9 discusses the application of differential evolution in two important areas of applied electromagnetics. Chapters 10 and 11 focus on applications of hybrid DE algorithms to problems in power system optimization. Chapter 12 applies the DE algorithm to computer chess. The use of DE to solve a problem in bioprocess engineering is discussed in Chapter 13. Chapter 14 describes the application of hybrid differential evolution to a problem in control engineering.
