Darwin's theory of evolution by natural selection was based on the
observation that there is variation between individuals within the
same species. This fundamental observation is a central concept in
evolutionary biology. However, variation is only rarely treated
directly. It has remained peripheral to the study of mechanisms of
evolutionary change. The explosion of knowledge in genetics,
developmental biology, and the ongoing synthesis of evolutionary
and developmental biology has made it possible for us to study the
factors that limit, enhance, or structure variation at the level of
an animals' physical appearance and behavior. Knowledge of the
significance of variability is crucial to this emerging synthesis.
This volume situates the role of variability within this broad
framework, bringing variation back to the center of the
evolutionary stage.
This book describes the role of the obligate inhabitants of all vertebrate genomes-endogenous retroviruses, especially those emerged in genomes rather recently, during primate evolution. It specially focuses on human endogenous retroviruses as well as other retroelements.
As a review of the status of biogeography in the West Indies in the 1980s, the first edition of Biogeography of the West Indies: Past, Present, and Future provided a synthesis of our current knowledge of the systematics and distribution of major plant and animal groups in the Caribbean basin. The totally new and revised Second Edition, Biogeography of the West Indies: Patterns and Perspectives, emphasizes recent ideas and hypotheses in the field and includes many new chapters and contributions. The authors use the broadest possible interpretations of the concepts of biogeography, consider anthropological and geological factors, and discuss the conservation of endemic species. Drawing together contributions from the leading experts in biogeography and biodiversity, this book introduces new patterns and developments that add to our understanding of how plants and animals are dispersed throughout the region. Many contributions use new techniques such as molecular systematics to test older studies based strictly on morphological data. Unique in its inclusion of a wide variety of organisms and in its coordination of scientific data and conservation strategies, Biogeography of the West Indies: Patterns and Perspectives, Second Edition provides the only encyclopedic discussion available on the biogeography of the Antilles.
In United States public schools, the content being taught in all subjects is determined by specialists who have the expertise necessary for the task. Parents don't insist on their opinions being part of curricular decisions. History, mathematics and literature classes, for example, generally enjoy full acceptance by parents and others. The science curriculum, however, is unique in that it has faced long-time opposition that shows little sign of lessening. Most notably, a controversy has arisen around biological evolution. Part history and part handbook, this carefully neutral work examines the origins of the opposition to biological evolution, its long and deep-seated history, and the reasons why it hasn't been resolved. Key terms - including creationism, evolution, intelligent design, and theory, among others - are defined at length, and erroneous understandings are addressed. Solutions are suggested so that the energies of school administrators and teachers may focus on their main task, the improvement of learning. State-by-state science standards are covered, and several models for biological science curricula are offered. Presented in a highly readable style, this study is intended for use by students, parents, teachers, school administrators, and community leaders alike, as well as others interested in the controversy.
Thought in a Hostile World is an exploration of the evolution of cognition, especially human cognition, by one of today's foremost philosophers of biology and of mind. The central idea of the book is that thought is a response to threat. Competitors and enemies make life hard by their direct physical effects. But they also make life hard by eroding epistemic conditions. They lie. They hide themselves. They seem other than what they are. Sterelny uses this and related ideas to explore from an evolutionary perspective the relationship between folk psychology and an integrated scientific conception of human cognition. In the process, he examines how and why human minds have evolved. The book argues that humans are cognitively, socially, and sexually very unlike the other great apes, and that despite our relatively recent separation from their lineages, human social and cognitive evolution has been driven by unusual evolutionary mechanisms. In developing his own picture of the descent of the human mind, Sterelny further offers a critique of nativist, modular versions of evolutionary psychology. This volume will be of vital interest to scholars and students interested in cognitive science, philosophy of mind, and evolutionary psychology.
Where did we come from? Where are we going? Homo sapiens is the most successful, the most widespread and the most influential species ever to walk the Earth. In the blink of an evolutionary eye we have spread around the globe, taken control of Earth's biological and mineral resources, transformed the environment, discovered the secrets of the universe and travelled into space. Yet just 7 million years ago, we were just another species of great ape making a quiet living in the forests of East Africa. We do not know exactly what this ancestor was like, but it was no more likely than a chimpanzee or gorilla to sail across the ocean, write a symphony, invent a steam engine or ponder the meaning of existence. How did we get from there to here? Human Origins recounts the most astonishing evolutionary tale ever told. Discover how our ancestors made the first tentative steps towards becoming human, how we lost our fur but gained language, fire and tools, how we strode out of Africa, invented farming and cities and ultimately created modern civilisation - perhaps the only one of its kind in the universe. Meet your long-lost ancestors, the other humans who once shared the planet with us, and learn where the story might end. ABOUT THE SERIES New Scientist Instant Expert books are definitive and accessible entry points to the most important subjects in science; subjects that challenge, attract debate, invite controversy and engage the most enquiring minds. Designed for curious readers who want to know how things work and why, the Instant Expert series explores the topics that really matter and their impact on individuals, society, and the planet, translating the scientific complexities around us into language that's open to everyone, and putting new ideas and discoveries into perspective and context.
Mudskippers are amphibious fishes native to the Indo-West Pacific and tropical western Africa. Unlike most fishes, mudskippers emerse to forage, find mates, and defend territories. Adaptations to their morphology, physiology and behavior enable mudskippers to accommodate both aquatic and terrestrial habitats. For these traits, mudskippers have long captured the fascination of scientists, naturalists, and fish hobbyists. Some mudskipper taxa (e.g. Periophthalmodon spp., Periophthalmus spp., Boleophthalmus spp.) are readily observed on mudflats and mangrove forests during the ebb tide. Correspondingly, these conspicuous and widespread taxa are relatively well-studied. The autecology and basic biology for the remaing taxa (e.g. Apocryptodon spp. and Oxuderces spp.) are still poorly understood. Fishes Out of Water: Biology and Ecology of Mudskippers is the first comprehensive book to synthesize published scientific information and observation on these fishes. Two dozen subject experts present thorough overviews in fifteen distinct chapters. Contents span mudskipper anatomy, distribution, systematics, physiology, ecology, and conservation. Unique adaptations to terrestriality are discussed within the context of each chapter foci. This authoritative reference equips the reader with the basic foundation to understand mudskipper biology and ecology, while providing a framework in which emerging data are discussed. The book will be of interest to a broad range of students, researchers, and professionals in ichthyology, evolution, ecology, animal behavior, and comparative physiology.
This book summarizes the knowledge in the field of methods to identify signatures of natural selection. A number of mathematical models and methods have been designed to identify the fingerprints of natural selection on genes and genomes. Such methods are provided in a simple and direct way so that students of different disciplines can navigate through molecular fitness landscapes using complex methods with a basic knowledge on bioinformatics. A collection of the main methods to detect selection in protein-coding genes and amino acid sequences is given at different levels of complexity, from nucleotides to proteins and molecular networks. The importance of identifying natural selection in genes and genomes through the methods described in this book transcends the bioinformatics and computational biology fields, presenting applications for experimental biologists in a straightforward and understandable way.
Originally published in 1982, The Masterpiece of Nature examines sex as representative of the most important challenge to the modern theory of evolution. The book suggests that sex evolved, not as the result of normal Darwinian processes of natural selection, but through competition between populations or species - a hypothesis elsewhere almost universally discredited. The book also discusses the nature of sex and its consequences for the individual and for the population, as well as various other theories of sex. Since the value of these theories is held to reside wholly in their ability to predict the patterns of sexuality observed in nature, the book seeks to provide an extensive review of the circumstances in which sexuality is attenuated or lost throughout the animal kingdom, and these facts are then used to weigh up the merits of the rival theories. This book will be of interest to researchers in the area of genetics, ecology and evolutionary biology.
This book provides a comprehensive overview of the design, generation and characterization of minimal cell systems. Written by leading experts, it presents an in-depth analysis of the current issues and challenges in the field, including recent advances in the generation and characterization of reduced-genome strains generated from model organisms with relevance in biotechnology, and basic research such as Escherichia coli, Corynebacterium glutamicum and yeast. It also discusses methodologies, such as bottom-up and top-down genome minimization strategies, as well as novel analytical and experimental approaches to characterize and generate minimal cells. Lastly, it presents the latest research related to minimal cells of serveral microorganisms, e.g. Bacillus subtilis. The design of biological systems for biotechnological purposes employs strategies aimed at optimizing specific tasks. This approach is based on enhancing certain biological functions while reducing other capacities that are not required or that could be detrimental to the desired objective. A highly optimized cell factory would be expected to have only the capacity for reproduction and for performing the expected task. Such a hypothetical organism would be considered a minimal cell. At present, numerous research groups in academia and industry are exploring the theoretical and practical implications of constructing and using minimal cells and are providing valuable fundamental insights into the characteristics of minimal genomes, leading to an understanding of the essential gene set. In addition, research in this field is providing valuable information on the physiology of minimal cells and their utilization as a biological chassis to which useful biotechnological functions can be added.
The volume is collection of articles treating the topic of human improvement/enhancement from a variety of perspectives - philosophical, literary, medical, genetic, sociological, legal etc. The chapters in this volume treat not only those aspects that most immediately come to mind when one thinks of 'human enhancement', such as genetic engineering, cloning, artificial implants and artificial intelligence etc. Somewhat less obvious aspects include evolutionary perspectives in connection with the prolongation of the human lifespan, plastic surgery since its beginnings, and questions such as whether the distinction between 'natural' and 'artificial' can really be drawn at all and how it has been conceived across the ages, or what the legal implications are of recent developments and techniques. Many papers make links to the representation of these developments in popular culture, from Jules Verne through Aldous Huxley to the movie Gattaca, address the hopes and fears that come with them as well as the question how realistic these are. While all chapters are written by scientists at the international top of their respective fields, all are accessible to a non-specialist audience and eminently readable. We believe that they represent a state-of-the art overview of questions that are of interest to a large audience. The book thus targets a non-specialist audience with an interest in philosophical, sociological, scientific and legal issues involved in both traditional and recent matters concerning the desire of mankind to improve itself, the human body, the human mind and the human condition. It is unique in that it brings together all these aspects within a coherent and cohesive collection.
There is only one kind of human on earth today: us. But we are only one of a number of human species - primates of the Hominini tribe - that have existed on our planet across the millennia. In 2004 the world was astounded by the discovery of Homo floresiensis, a species of human never encountered before, on the island of Flores in the Indonesian archipelago. A very short, thickset being, with long arms and feet and an appetite for stegodons (a now extinct relative of modern elephants), it was soon nicknamed 'the hobbit'. As recently as 52,500 years ago, at a time when our own ancestors were spreading around the world, these 'hobbit' cousins lived also, at least on Flores. In Little Species, Big Mystery archaeologist Debbie Argue takes us on a journey of thrilling scientific discovery, recounting the unearthing of H. floresiensis, the archaeological expeditions that have followed, other finds - including that of a small Philippines hominin - and new paths of research and discussion. Argue conveys the excitement of searching for and finding clues to a lost past, and the animated discussions that have flowed from their discovery. She provides much contextual information to strengthen our grasp of the essential coordinates of this field and stimulate our interest in the shadowy, fascinating realm of prerecorded time.
Huxley was one of the first adherents to Darwin's theory of evolution by natural selection and advanced its acceptance by scientists and the public. "Man's Place in Nature" was explicitly directed against Richard Owen, who had claimed that there were distinct differences between human brains and those of apes. Huxley demonstrated that ape and human brains were fundamentally similar in every anatomical detail, thus applying evolution to the human race.
Owen was the founder of the Natural History Museum, bringing the collections over from the British Museum. Although he was a supporter of evolutionary theory, he was reluctant to accept Darwin's version of evolution. This volume examines fossil evidence for change in species over time.
Moving away from his earlier belief in a short, catastrophic history of the Earth, Buckland's treatise envisages instead and propounds the theory of a course of progressive change that occurred as the Earth gradually cooled and became ready for human occupation. During this time, the creatures that first walked the Earth did not die out because they were poorly designed; God loved the dinosaurs and had adapted them to their various circumstances.
Crustaceans, due to the great diversity of their body organization,
segmentation patterns, tagmatization, limb types, larval forms,
cleavage, and gastrulation modes, are highly desirable for the
study of questions at the interface of evolution and development.
Modern interest in evolutionary developmental biology (evo-devo)
rests on the molecular genetic approach and a variety of molecular
techniques have proven fruitful when performed on crustaceans.
More often than not, when people think of a neotropical forest, what comes to mind is a rain forest, rather than a dry forest. Just as typically, when they imagine a savanna, they visualize the African plains, rather than those dry woodlands and grasslands found in the Neotropics. These same preconceptions can be found among scientists, as these neotropical biomes receive nowhere near the attention they should - in terms of both research and conservation -considering the amount of land they encompass and the diversity of vegetation they contain. Neotropical Savannas and Dry Forests: Plant Diversity, Biogeography, and Conservation provides an engaging synthesis of information on the plant diversity and geography, as well as the conservation status, of these species-rich areas. This impressive compilation is the result of a plant diversity symposium that took place during an international conference on tropical savannas and seasonally dry forests held in 2003. Fifty leading scientists, representing a variety of disciplines have contributed to the chapters of this book in an effort to address three questions: What are the patterns of diversity, species-richness and endemism of the floras of neotropical seasonally dry forest and savannas? How and why did this endemism and diversity arise? Are these ecosystems adequately protected and, if not, which areas should be elevated into priorities for conservation, and how can this be best achieved? This work is the first extensive compilation of the patterns of plant biodiversity in these neotropical ecosystems. The overview also provides a summary of what is known of their evolutionary history, including an examination of the links to the development of analogous vegetation in Africa. In contrast to previously published titles that emphasize ecology and physiology, this work focuses on plant biodiversity and reviews molecular phylogenetic and molecular population genetic approache
An accessible and straightforward intro to cell biology In the newly revised Fourth Edition of Cell Biology: A Short Course, a distinguished team of researchers delivers a concise and accessible introduction to modern cell biology, integrating knowledge from genetics, molecular biology, biochemistry, physiology, and microscopy. The book places a strong emphasis on drawing connections between basic science and medicine. Telling the story of cells as the units of life in a colorful and student-friendly manner, Cell Biology: A Short Course takes an "essentials only" approach. It conveys critical points without overburdening the reader with extraneous or secondary information. Clear diagrams and examples from current research accompany special boxed sections that focus on the importance of cell biology in medicine and industry. A new feature, "BrainBoxes" describes some of the key people who created the current understanding of Cell Biology. The book has been thoroughly revised and updated since the last edition and includes: Thorough introduction to cells and tissues, membranes, organelles, and the structure of DNA and genetic code Explorations of DNA as a data storage medium, transcription and the control of gene expression, and recombinant DNA and genetic engineering Discussion of the manufacture of proteins, protein structure, and intracellular protein trafficking Description of ions and voltages, intracellular and extracellular signaling Introduction to the cytoskeleton and cell movement Discussion of cell division and apoptosis Perfect for undergraduate students seeking an accessible, one-stop reference on cell biology, Cell Biology: A Short Course is also an ideal reference for pre-med students.
There is a revolution underway in biology. It is based on a new perception of bodies and genes, in which the former are the end product of the latter within the continuum of evolution. Twenty five years after Richard Dawkins helped revolutionize our thinking about "selfish genes," it is time to re-evaluate. "Revolutionary Biology" explains in simple, vivid terms what this exciting approach has to offer, and then applies its stunning insights to human beings. This novel perspective, galvanizes our understanding of how evolution works, what living things are all about and, not least what it means to be human. The controversial disciplines of sociobiology and evolutionary psychology have generated startling insights into longstanding questions concerning the nature and purpose of families, altruism vs. selfishness, and free will vs. biological determinism. Written by one of its foremost figures, "Revolutionary Biology" is a manifesto and educated layman's guide to this ongoing revolution. Barash's purpose is to demystify the basic concepts of the genetic revolution and take the reader on a tour--accessible and authoritative--of the principles that underlie this fascinating turn in scientific thought. Much has been written about evolution, animals, and the animal and evolutionary origins of human behavior, yet only recently have biologists begun to appreciate these connections. The key concept is that genes--not species, not groups, and not even individuals--are the apple of evolution's eye. The result has been a major biological paradigm shift that is making itself felt in the social sciences as well. Barash explores the phenomenon of altruism both at the animal level, and the human level. Barash draws not only on a wealth of biological evidence but on literature, philosophy, and the familiar details of everyday life to communicate the essentials of this increasingly influential approach to the study of the human species. Clearly and engagingly written, "Revolutionary Biology" will be fascinating reading for those seeking an entry into this new science.
Appropriate as a textbook for graduate courses, "The Evolution and
Function of Cognition" provides a systematic and progressively
inclusive integration of the facts and principles of cognitive
psychology. It includes contributions of information processing and
reaction, and emphasizes historical continuity. In addition, the
book shows how evolutionary psychology fits in with the mainstream
of thought in psychological theory.
"Evolutionism in Cultural Anthropology"traces the interaction of evolutionary thought and anthropological theory from Herbert Spencer to the twenty-first century. It is a focused examination of how the idea of evolution has continued to provide anthropology with a master principle around which a vast body of data can be organized and synthesized. Erudite and readable, and quoting extensively from early theorists (such as Edward Tylor, Lewis Henry Morgan, John McLennan, Henry Maine, and James Frazer) so that the reader might judge them on the basis of their own words, "Evolutionism in Cultural Anthropology" is useful reading for courses in anthropological theory and the history of anthropology.
