This book challenges the assumption that morphological data are inherently unsuitable for phylogeny reconstruction, argues that both molecular and morphological phylogenies should play a major role in systematics, and provides the most comprehensive review of the comparative anatomy, homologies and evolution of the head, neck, pectoral and upper limb muscles of primates. Chapters 1 and 2 provide an introduction to the main aims and methodology of the book. Chapters 3 and 4 and Appendices I and II present the data obtained from dissections of the head, neck, pectoral and upper limb muscles of representative members of all the major primate groups including modern humans, and compare these data with the information available in the literature. Appendices I and II provide detailed textual (attachments, innervation, function, variations and synonyms) and visual (high quality photographs) information about each muscle for the primate taxa included in the cladistic study of Chapter 3, thus providing the first comprehensive and up to date overview of the comparative anatomy of the head, neck, pectoral and upper limb muscles of primates. The most parsimonious tree obtained from the cladistic analysis of 166 head, neck, pectoral and upper limb muscle characters in 18 primate genera, and in representatives of the Scandentia, Dermoptera and Rodentia, is fully congruent with the evolutionary molecular tree of Primates, thus supporting the idea that muscle characters are particularly useful to infer phylogenies. The combined anatomical materials provided in this book point out that modern humans have fewer head, neck, pectoral and upper limb muscles than most other living primates, but are consistent with the proposal that facial and vocal communication and specialized thumb movements have probably played an important role in recent human evolution. This book will be of interest to primatologists, comparative anatomists, functional morphologists, zoologists, physical anthropologists, and systematicians, as well as to medical students, physicians and researchers interested in understanding the origin, evolution, homology and variations of the muscles of modern humans. Contains 132 color plates.
Conservation genetics focuses on understanding the role and
requirement of genetic variation for population persistence.
However, considerable debate now surrounds the role of genetic
factors (as opposed to non-genetic factors such as habitat
destruction etc.) in population extinction, and a comprehensive
synthesis is now timely. Can extinction be explained by habitat
destruction alone or is lack of genetic variation a part of the
explanation? The book thoroughly reviews the arguments for a role
of genetics in the present biodiversity crisis. It describes the
methods used to study genetic variation in endangered species and
examines the influence of genetic variation in the extinction of
species.
Evolution: The Basics is an engaging introduction to the history, development and science of the theory of evolution. Beginning pre-Darwin and concluding with the latest research and controversies, readers are introduced to the origins of the idea of evolution, the ways in which it has developed and been adapted over time and the science underpinning it all. Topics addressed include: ? early theories of evolution Evolution: The Basics examines the role of evolution in current debates and discusses the possible future developments in the field. This book is invaluable reading for all students and individuals seeking to understand the wide ranging sphere of evolutionary theory.
This provocative study provides a stimulating critique of contemporary evolutionary thought, analysing the Modern Synthesis first developed by Theodosius Dobzhansky, Ernst Mayr, and George Gaylord Simpson. Written by an eminent evolutionary biologist (the co-founder of the theory of punctuated equilibria), this highly readable book argues that only genes and organisms are taken as historic 'individuals' in conventional theory. Eldredge proposes that species, higher taxa, and ecological entities such as populations and communities should also be construed as individuals - an approach yielding the ecological and genealogical hierarchies that interact to produce evolution. This clearly stated, controversial work will provoke much debate among evolutionary biologists, systematicists, palaeontologists and ecologists, as well as lay readers.
The order Rodentia is the most abundant and successful group of mammals, and it has been a focal point of attention for compar ative and evolutionary biologists for many years. In addition, rodents are the most commonly used experimental mammals for bio medical research, and they have played a central role in investi gations of the genetic and molecular mechanisms of speciation in mammals. During recent decades, a tremendous amount of new data from various aspects of the biology of living and fossil rodents has been accumulated by specialists from different disciplines, ranging from molecular biology to paleontology. Paradoxically, our understanding of the possible evolutionary relationships among different rodent families, as well as the possible affinities of rodents with other eutherian mammals, has not kept pace with this information "explosion. " This abundance of new biological data has not been incorporated into a broad synthesis of rodent phylo geny, in part because of the difficulty for any single student of rodent evolution to evaluate the phylogenetic significance of new findings from such diverse disciplines as paleontology, embryology, comparative anatomy, molecular biology, and cytogenetics. The origin and subsequent radiation of the order Rodentia were based primarily on the acquisition of a key character complex: specializations of the incisors, cheek teeth, and associated mus culoskeletal features of the jaws and skull for gnawing and chewing."
Originally published in 1969, the aim of this book is to tell the story of the major discoveries which have been made and the attitude of the world at large to these discoveries during the ten decades since Darwin published On the Origin of Species in 1859. For anyone interested in man's past and in understanding the significance of each new discovery relating to human evolution, this reissue will be of great value.
'Steve Brusatte, the author of The Rise and Fall of the Dinosaurs, brings mammals out from the shadow of their more showy predecessors in a beautifully written book that . . . makes the case for them as creatures who are just as engaging as dinosaurs.' - The Sunday Times, 'Best Books For Summer' 'In this terrific new book, Steve Brusatte . . . brings well-known extinct species, the sabre-toothed tigers and the woolly mammoths, thrillingly back to life' - The Times The passing of the age of the dinosaurs allowed mammals to become ascendant. But mammals have a much deeper history. They - or, more precisely, we - originated around the same time as the dinosaurs, over 200 million years ago; mammal roots lie even further back, some 325 million years. Over these immense stretches of geological time, mammals developed their trademark features: hair, keen senses of smell and hearing, big brains and sharp intelligence, fast growth and warm-blooded metabolism, a distinctive line-up of teeth (canines, incisors, premolars, molars), mammary glands that mothers use to nourish their babies with milk, qualities that have underlain their success story. Out of this long and rich evolutionary history came the mammals of today, including our own species and our closest cousins. But today's 6,000 mammal species - the egg-laying monotremes including the platypus, marsupials such as kangaroos and koalas that raise their tiny babies in pouches, and placentals like us, who give birth to well-developed young - are simply the few survivors of a once verdant family tree, which has been pruned both by time and mass extinctions. In The Rise and Reign of the Mammals, palaeontologist Steve Brusatte weaves together the history and evolution of our mammal forebears with stories of the scientists whose fieldwork and discoveries underlie our knowledge, both of iconic mammals like the mammoths and sabre-toothed tigers of which we have all heard, and of fascinating species that few of us are aware of. For what we see today is but a very limited range of the mammals that have existed; in this fascinating and ground-breaking book, Steve Brusatte tells their - and our - story.
The book is a telepathic communication between myself and Dar, a evolved human from 23 million years in the future, as well as several other guides, spiritual and otherwise, from various future time periods. Although most of the contact is through Dar, several of his companions, from various timelines from a few centuries to over 1000 million years in the future have made some observations about various time periods. The book covers technology, spirit guides, singularities, timelines, evolution, time travel, parallel worlds, future cities and other realities. It also covers altered states of consciousness, the 2012 event, space travel, time lines, advanced data storage, power generation, future history and my notes. There is discussion in time and the nature of reality, as well as technological development and where it is leading us into the future. It is about possibilities, and I do not mean it to be either a positive or negative statement, but an observation of what is. I hope the book will encourage some people to objectively seek out alternative possibilities.
When faced with new challenges, it's easy to feel our solutions need to be equally unprecedented. We think we need a revolution. But what if this is a big mistake? In Evolutionary Ideas, Sam Tatam shows how behavioural science and evolutionary psychology can help us solve tomorrow's challenges, not by divining something the world has never seen, but by borrowing from yesterday's solutions - often in the most unexpected ways. Just as millions of years of evolution have helped craft the wing and dorsal fin, thousands of engineers, designers, marketers and advertisers have toiled to solve many of the problems you face today. Over time, through intent, design, social learning and sheer luck, we have found what works. Armed with an enhanced ability to see these patterns in human innovation, we can now systematically approach the creative process to develop more effective ideas more readily and rapidly. Just as Japanese engineers reduced bullet train noise by studying the evolved biology of the owl and kingfisher, today we can see how Disney improved the queueing experience in the same way Houston airport made arrivals feel faster (while making people walk further). We'll learn how the chocolate at the bottom of a Cornetto ice cream can improve an Error 404 message, and what a bowl of M&Ms has in common with a canary in a coal mine. These are Evolutionary Ideas. Exploring five of the most critical challenges we face today, we learn how to 'breed' more effective solutions from those that have survived. The result is a dynamic and exciting way of solving problems and supercharging creativity - for anyone in any endeavour.
Through a series of essays concerning human eating seen from the perspective of contemporary biology/medicine and recent research articles, the book explores the links between food and Man's cultural and physical evolution. Each chapter has an introduction summarizing the basic knowledge in the field, discusses the recent research results, and confirms or challenges the established concepts, which opens new aspects and leads to new questions. This book catalyzes discussion between scientists working on one side in food science and on the other side in biological and biomedical research.
Since the publication of The New Science of Astrobiology in the year 2001 the first edition of the present book two significant events have taken place raising the subject from the beginning of the present century to its present maturity. Firstly, in 2001 the Galileo Mission still had two years to complete its task, which turned out to be an outstanding survey of the Jovian system, especially of its intriguing satellite Europa. Secondly, the Cassini Huygens Mission was still on its way to Saturn. Its present success has surpassed all expectations of ESA and NASA. Astrobiologists still did not know that Titan was the fifth body in the Solar System that possibly contained a water ocean (including the Earth and the three Galilean satellites other than Io). For these reasons the book includes overviews of the evolutionary and molecular biology that are necessary. There is a discussion of other sectors of culture that are the natural frontiers of astrobiology, especially the humanities."
This is the only English-language publication devoted exclusively to extensive reviews and synthesis of topics on the biology of birds. The current volume includes articles on sibling competition, predation and the limitation of bird numbers, and population trends in birds of eastern North America.
This book is a collection of original research papers given at a symposium entitled "Sensory Systems and Behavior of Aquatic Mammals", hosted by the USSR Academy of Sciences. The meeting was held in Moscow from 16 to 25 October, 1991 and involved nearly 100 scientists from around the world. The major headings of the book correspond to the session topics at the symposium. This meeting was not the first dedicated to problems of sensory systems in aquatic mammals. Experts in this field met several times previously to discuss important problems of sensory functions in echolocating animals. symposia on biosonar systems were held in Frascati, Italy in 1966, then in Jersey, France in 1978, and in Helsingor, Denmark in 1986. Papers presented at these meetings were pUblished in books that advanced significantly the understanding of sensory systems (Busnel and Fish, 1980; Nachtigall and Moore, 1988). Initially, echolocating bats were the main subjects of consideration. However, studies on echolocating aquatic mammals, whales and dolphins, increased from one meeting to the next. Indeed, aquatic mammals are of exceptional interest for studying the adaptation of sensory functions for echolocation in specific aquatic environments. As a natural consequence of these developments, the 1989 symposium in Rome was devoted specifically to the sensory systems of cetaceans (Thomas and Kastelein, 1990). This symposium was held within the Fifth International Theriological Congress and was attended by many scientists.
This volume is an up-to-date treatise of chemosensory vertebrate research performed by over 200 scientists from 22 countries. Importantly, data from over 25 taxa of vertebrates are presented, including those from human beings. Unlike other volumes on this topic, a significant nurober of the contributions come from leading workers in the former Soviet Union and reflect studies within a wide variety of disciplines, including behavior, biochemistry, ecology, endocrinology, genetics, psychophysics, and morphol ogy. Most of the studies described in this volume were presented at the Chemical Signals in Vertbrates VI (CSV VI) symposium held at the University of Pennsylvania in the summer of 1991. This international symposium was the largest and the most recent of a series of six such symposia, the first of which was held in Saratoga Springe, New York (June 6-9, 1976) and the last in Oxford, England (August 8-10, 1988). Unlike the previous symposia, Chemical Signals in Vertabrates VI lasted a full week, reflecting the increased number of participants and the desire of many to present their research findings orally to the group as a whole."
These essays are primarily concerned with the character of ethological research in the context of conflicts between animal and human interests. Specifically, to what extent is the projection into animals of human feelings a useful means to understand animal behavior? Annotation copyright Book News,
This volume provides in-depth reviews of model systems that exemplify the arms race in host-pathogen interactions. Somatic adaptations are responsible for the individualization of biological responses to the environment, and the continual struggle between host immune systems and invading pathogens has given rise to corresponding processes that produce molecular variation. Whether in mollusks or human beings, various host somatic mechanisms have evolved independently, providing responses to counter rapidly-changing pathogens. The pathways they utilize can include non-heritable changes involving RNA and post-translational modifications, or changes that produce somatic DNA recombination and mutation. For infectious organisms such as protozoans and flatworms, antigenic variation is central to their survival strategy. Evolving the ability to evade the host immune system not only increases their chances of survival but is also necessary for successful re-infection within the host population.
In this book, the editors present a view of the socioecology of primates and cetaceans in a comparative perspective to elucidate the social evolution of highly intellectual mammals in terrestrial and aquatic environments. Despite obvious differences in morphology and eco-physiology, there are many cases of comparable, sometimes strikingly similar patterns of sociobehavioral complexity. A number of long-term field studies have accumulated a substantial amount of data on the life history of various taxa, foraging ecology, social and sexual relationships, demography, and various patterns of behavior: from dynamic fission-fusion to long-term stable societies; from male-bonded to bisexually-bonded to matrilineal groups. Primatologists and cetologists have come together to provide four evolutionary themes: (1) social complexity and behavioral plasticity, (2) life history strategies and social evolution, (3) the interface between behavior, demography, and conservation, and (4) selected topics in comparative behavior. These comparisons of taxa that are evolutionarily distant but live in comparable complex sociocognitive environments boost our appreciation of their sophisticated mammalian societies and can advance our understanding of the ecological factors that have shaped their social evolution. This knowledge also facilitates a better understanding of the day- to-day challenges these animals face in the human-dominated world and may improve the capacity and effectiveness of our conservation efforts.
Ever since Darwin, the world has been struggling with the mystery of human diversity. As the historian Peter Bowler has written, an evolutionary interpretation of the history of life on the earth must inevitably extend itself to include the origins of the human race. But this has proved to be a difficult and controversial task. Understanding human origins means accounting not only for the obvious differences between people and cultures around the world, but also for the unity of "Homo sapiens" as a single biological species. As Stephen Jay Gould has said, flexibility is the hallmark of human evolution. Because so much of who we are is learned rather than genetically predetermined, a satisfactory understanding of human evolution--to use old parlance--must account both for the human body and the human soul. At any single moment of time, it is always possible to find instances where people seem to live in their own world, speak in their own distinctive ways, and have their own exclusive cultural traits and practices. Over the course of time, however, it is not so easy to find places where these dimensions of our diversity stay together. The essays in this collection show why we must stop thinking that race, language, and culture go together, and why we should be wary of the commonsense beliefs that human races exist and that people who speak different languages come from fundamentally different biological lineages.
This book forms part of the set, Comparative Anatomy and Posture of Animal and Human, and focuses on the skulls of Quaternary mammals and of Man since the acquisition of upright posture. Although the vast majority of the quadruped fossil species have a balanced postural adaptation, with no asymmetries or maxillo-mandibular dysmorphoses, the Hominine species that has acquired this readjustment of the body as well as a bipedal adaptation to the ground, will experience a series of postural imbalances starting with malocclusion in the genus Homo. In order to arrive at this conclusion, the cranio-facial architectural biodynamics of several species of fossil and current mammals have been analyzed over three decades. In addition, hundreds of skulls of anatomically modern Hominids have been examined, highlighting their occlusal offsets, variations, anomalies and pathologies.
Renowned science writer L. Sprague de Camp studies our global "wrong-headedness" by examining our primitive past. Writing with insight and humor, de Camp explores what makes us tick as the products - and victims - of our prehuman past. He delves into the legacy of evolution and shows how it has affected our historical and social development. The survival traits of our ancestors, which include foraging in bands, scrounging for food, and chasing other scavengers away from the kill, are at the heart of our highly competitive and combative nature - the tendency to view others as adversaries. Are we "only monkeys shaved"? Can we overcome our prehuman character? The Ape-Man Within answers these and other fundamental questions facing our global society.
If theoretical physicists can seriously entertain canonical "standard models" even for the big-bang generation of the entire universe, why cannot life scientists reach a consensus on how life has emerged and settled on this planet? Scientists are hindered by conceptual gaps between bottom-up inferences (from early Earth geological conditions) and top-down extrapolations (from modern life forms to common ancestral states). This book challenges several widely held assumptions and argues for alternative approaches instead. Primal syntheses (literally or figuratively speaking) are called for in at least five major areas. (1) The first RNA-like molecules may have been selected by solar light as being exceptionally photostable. (2) Photosynthetically active minerals and reduced phosphorus compounds could have efficiently coupled the persistent natural energy flows to the primordial metabolism. (3) Stochastic, uncoded peptides may have kick-started an ever-tightening co-evolution of proteins and nucleic acids. (4) The living fossils from the primeval RNA World thrive within modern cells. (5) From the inherently complex protocellular associations preceding the consolidation of integral genomes, eukaryotic cell organization may have evolved more naturally than simple prokaryote-like life forms. - If this book can motivate dedicated researchers to further explore the alternative mechanisms presented, it will have served its purpose well. |
