This title discusses the study of evolution through the analysis of biomechanical systems. Instead of reviewing the entire breadth of the biomechanical literature, a few key examples are explored in depth as vehicles for discussing fundamental concepts, analytical techniques, and evolutionary theory.
The classic textbook on comparative biomechanics—revised and expanded Why do you switch from walking to running at a specific speed? Why do tall trees rarely blow over in high winds? And why does a spore ejected into air at seventy miles per hour travel only a fraction of an inch? Comparative Biomechanics is the first and only textbook that takes a comprehensive look at the mechanical aspects of life—covering animals and plants, structure and movement, and solids and fluids. An ideal entry point into the ways living creatures interact with their immediate physical world, this revised and updated edition examines how the forms and activities of animals and plants reflect the materials available to nature, considers rules for fluid flow and structural design, and explores how organisms contend with environmental forces. Drawing on physics and mechanical engineering, Steven Vogel looks at how animals swim and fly, modes of terrestrial locomotion, organism responses to winds and water currents, circulatory and suspension-feeding systems, and the relationship between size and mechanical design. He also investigates links between the properties of biological materials—such as spider silk, jellyfish jelly, and muscle—and their structural and functional roles. Early chapters and appendices introduce relevant physical variables for quantification, and problem sets are provided at the end of each chapter. Comparative Biomechanics is useful for physical scientists and engineers seeking a guide to state-of-the-art biomechanics. For a wider audience, the textbook establishes the basic biological context for applied areas—including ergonomics, orthopedics, mechanical prosthetics, kinesiology, sports medicine, and biomimetics—and provides materials for exhibit designers at science museums. Problem sets at the ends of chapters Appendices cover basic background information Updated and expanded documentation and materials Revised figures and text Increased coverage of friction, viscoelastic materials, surface tension, diverse modes of locomotion, and biomimetics
From the rain forests of Borneo to the tenements of Manhattan, winged insects are a conspicuous and abundant feature of life on earth. Here, Robert Dudley presents the first comprehensive explanation of how insects fly. The author relates the biomechanics of flight to insect ecology and evolution in a major new work of synthesis. The book begins with an overview of insect flight biomechanics. Dudley explains insect morphology, wing motions, aerodynamics, flight energetics, and flight metabolism within a modern phylogenetic setting. Drawing on biomechanical principles, he describes and evaluates flight behavior and the limits to flight performance. The author then takes the next step by developing evolutionary explanations of insect flight. He analyzes the origins of flight in insects, the roles of natural and sexual selection in determining how insects fly, and the relationship between flight and insect size, pollination, predation, dispersal, and migration. Dudley ranges widely--from basic aerodynamics to muscle physiology and swarming behavior--but his focus is the explanation of functional design from evolutionary and ecological perspectives. The importance of flight in the lives of insects has long been recognized but never systematically evaluated. This book addresses that shortcoming. Robert Dudley provides an introduction to insect flight that will be welcomed by students and researchers in biomechanics, entomology, evolution, ecology, and behavior.
Origins and Principles of Clinical Biomechanics in Human Locomotion discusses key concepts of how biomechanics links to the development of pathology through mechanical laws, anatomy, physiology and health. It provides fundamental principles and practical data, and guidance of how to apply these in the clinical biomechanics field. Coverage includes: major joint movement, muscle action around joints, physiology and patho-physiology of bone, muscle and neurologic disorders. This reference is ideal for teaching students in biomechanics, orthopedics and physiotherapy. It should also be of interest to product development engineers, rehabilitation engineers, those working in prosthetics and orthotics, physiotherapists and occupational therapists. The authors explore the simple laws of motion as applied to anatomy and physiology, in order to help readers understand human pathology within the human lower limb and mobility. They then go on to look at materials science concerns within this field, such as engineering stresses and strains, principles and types of material properties and the shaping of structural properties. Readers will also find within this book information on tissue science, force generation, biological sciences, evolution in biomechanics, human gait, functional units of the lower limb and foot, and finally pathomechanical principles; all as applied to clinical biomechanics. - Bridges the void between research biomechanics and clinically applied biomechanics - Links human locomotive biomechanics to medicine, physiology and evolutionary anatomy and medicine - Prepares students, bioengineers and clinicians for the reality of utilizing biomechanical principles in clinical practice, while informing researchers of the environment limits that most clinical biomechanics practice occurs in
This book provides students and researchers with reviews of biological questions related to the evolution of feeding by vertebrates in aquatic and terrestrial environments. Based on recent technical developments and novel conceptual approaches, the book covers functional questions on trophic behavior in nearly all vertebrate groups including jawless fishes. The book describes mechanisms and theories for understanding the relationships between feeding structure and feeding behavior. Finally, the book demonstrates the importance of adopting an integrative approach to the trophic system in order to understand evolutionary mechanisms across the biodiversity of vertebrates.
The book tells the story of how we never evolved to exercise - to do voluntary physical activity for the sake of health. Using his own research and experiences throughout the world, the author recounts how and why humans evolved to walk, run, dig, and do other necessary and rewarding physical activities while avoiding needless exertion. Drawing on insights from biology and anthropology, the author suggests how we can make exercise more enjoyable, rather that shaming and blaming people for avoiding it
'Species' are central to understanding the origin and dynamics of biological diversity; explaining why lineages split into multiple distinct species is one of the main goals of evolutionary biology. However the existence of species is often taken for granted, and precisely what is meant by species and whether they really exist as a pattern of nature has rarely been modelled or critically tested. This novel book presents a synthetic overview of the evolutionary biology of species, describing what species are, how they form, the consequences of species boundaries and diversity for evolution, and patterns of species accumulation over time. The central thesis is that species represent more than just a unit of taxonomy; they are a model of how diversity is structured as well as how groups of related organisms evolve. The author adopts an intentionally broad approach, stepping back from the details to consider what species constitute, both theoretically and empirically, and how we detect them, drawing on a wealth of examples from microbes to multicellular organisms.
