This book was released on 2020-05-07 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1924 African discovery of an early hominin child's skull, referred to as Australopithecus africanus by Raymond Dart, was a major event in the history of paleoanthropology. This provided the first evidence of early hominins in Africa and overturned conventional ideas about human evolution. Subsequent discoveries of A. africanus fossils, notably from cave deposits at Sterkfontein, yielded the first evidence that early hominins were habitual bipeds. Fifty years after this, the discovered wealth of fossil evidence in eastern Africa of the slightly older and craniodentally more primitive taxon, A. afarensis, catalyzed debates about the origin and evolution of human gait and the phylogentic relationships among early hominins. This formed the main basis of our understanding of early hominin bipedality and paleobiology. Little attention has been paid to the variation among species in postcranial anatomy and locomotion, although intriguing hints are beginning to appear in the literature. Did multiple varieties of bipedality evolve? Did australopith species differ in positional or manipulative abilities, body proportions, or patterns of sexual dimorphism? These are critical questions for understanding the evolution of australopiths and hominin locomotion. In this book, Bernhard Zipfel, Brian Richmond, Carol Ward, and the most knowledgeable scholars in their respective fields provide groundbreaking accounts for each postcranial fossil and expert examinations into the background of each fossil. The chapters include standardized high-quality photographs and anatomical descriptions to allow readers to read the book entirely or learn by comparing features across chapters. Hominin Postcranial Remains from Sterkfontein, South Africa, 1936-1995 is an evolutionary history of South African hominins, and it offers readers an orientation and introduction to the field. This is an important reference book for professional paleontologists, paleobiologists, anthropologists, geologists, students, and historians interested in human evolution.

This book was released on 2020 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sterkfontein hominin fossils generally are attributed to the species Australopithecus africanus, because most craniodental remains from the site are attributable to that taxon (reviews in Grine, 2013, 2019). However, there may be more than one hominin represented within the sample, even within the most productive Member, Member 4, and given the complex stratigraphy of the site and challenges in dating the deposits, this may or not may be the case. In general. Several studies have suggested the presence of two or more australopith taxon within the sample, each citing more morphological variation among the craniodental remains from Sterkfontein that can be attributed to a single species, at least compared to extant hominoid taxa (Kimbel and White, 1988; Clarke 1988, 1994; Lockwood, 1997, Lockwood and Tobias, 2002). However, it is notable that none of these studies agree on which specimens comprise the different possible taxa or groups, largely due to emphasis on different aspects of morphology varying among the fossils. The likely time depth of the Sterkfontein sample, even within Member 4, (see Chapter 3, this volume), may also complicate assessment of potential taxonomic heterogeneity at the site. None of the Sterkfontein postcranial fossils can be definitively associated with any craniodental specimens (but see Thackeray et al., 2002), and so cannot be related directly to any of the proposed taxonomic divisions within the sample. However, some studies have cited variation within the postcranial fossils that may also reflect taxonomic variation, although many studies to date have not tackled this question rigorously. Even though these suggestions have been made occasionally in the literature, no clear or consistent suggestion of two or more taxa has been apparent within the postcranial samples (reviewed in Grine 2019). Taxonomic variation is one of the key questions that each chapter in this volume addresses (summarized in Chapter 18, this volume)"--

Download or read book Evolutionary Perspectives on Infancy written by Sybil L. Hart and published by Springer Nature. This book was released on 2022-01-01 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique volume is one of the first of its kind to examine infancy through an evolutionary lens, identifying infancy as a discrete stage during which particular types of adaptations arose as a consequence of certain environmental pressures. Infancy is a crucial time period in psychological development, and evolutionary psychologists are increasingly recognizing that natural selection has operated on all stages of development, not just adulthood. The volume addresses this crucial change in perspective by highlighting research across diverse disciplines including developmental psychology, evolutionary developmental psychology, anthropology, sociology, nutrition, and primatology. Chapters are grouped into four sections: Theoretical Underpinnings Brain and Cognitive Development Social/Emotional Development Life and Death Evolutionary Perspectives on Infancy sheds new light on our understanding of the human brain and the environments responsible for shaping the brain during early stages of development. This book will be of interest to evolutionary psychologists and developmental psychologists, biologists, and anthropologists, as well as scholars more broadly interested in infancy.
Download or read book Behaviour in our Bones written by Cara S. Hirst and published by Elsevier. This book was released on 2023-02-07 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exploring behaviour through bones has always been a fascinating topic to those that study human remains. Human bodies record and store vast amounts of information about the way we move, where we live, and our experiences of health and socioeconomic circumstances. We see it every day, and experience it, but when it comes to past populations, understanding behaviour is largely mediated by our ability to read it in bones. Behaviour in Our Bones: How Human Behaviour Influences Skeletal Morphology examines how human physical and cultural actions and interactions can be read through careful analyses of skeletal human remains. This book synthesises the latest research on reconstructing behaviour in the past. Each chapter is dedicated to a specific region of the human body, guiding the reader from head to toe and highlighting how evidence found on the skull, shoulder, thorax, spine, pelvis, and the upper and lower limbs has been used to infer patterns of activity and other behaviour. Chapter authors expertly summarise and critically discuss a range of methodological, theoretical, and interpretive approaches used to read skeletal remains and interpret a wide variety of behaviours, including tool use, locomotion, reproduction, health, pathology, and beyond. - Serves as a comprehensive resource for readers who are new to human skeletal behaviour investigations - Offers an overview on how behaviour may impact the entire skeleton (from head to toe) - Discusses activities that can leave evidence on the human skeleton and how behaviour can become incorporated in bone - Introduces methods that biological anthropologists use to quantify and interpret skeletal evidence for behaviour and its range of morphological variation - Critically examines the current state of skeletal behaviour research and provides recommendations for future work in this field

Download or read book From Biped to Strider written by D. Jeffrey Meldrum and published by Springer Science & Business Media. This book was released on 2011-06-27 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inspiration for this volume of contributed papers stemmed from conversations between the editors in front of Chuck Hilton's poster on the determinants of hominid walking speed, presented at thel998 meetings of the American Association of Physical Anthropologists (AAPA). Earlier at those meetings, Jeff Meldrum (with Roshna Wunderlich) had presented an alternate interpretation of the Laetoli footprints based on evidence of midfoot flexibility. As the discussion ensued we found convergence on a number of ideas about the nature of the evolution of modem human walking. From the continuation of that dialogue grew the proposal for a symposium which we called From Biped to Strider: the Emergence of Modem Human Walking. The symposium was held as a session of the 69th annual meeting of the AAPA, held in San Antonio, Texas in 2000. It seemed to us that the study of human bipedalism had become overshadowed by theoften polarized debates over whether australo pithecines were wholly terrestrial in habit, or retained a significant degree of arboreality.
Download or read book Plants and the Human Brain written by David O. Kennedy and published by Oxford University Press. This book was released on 2014-01-09 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: We're all familiar with the idea that plant-derived chemicals can have an impact on the functioning of the human brain. Most of us reach for a cup of coffee or tea in the morning, many of us occasionally eat some chocolate, some smoke a cigarette or take an herbal supplement, and some people use illicit drugs. We know a great deal about the mechanisms by which the psychoactive components of these various products have their effects on human brain function, but the question of why they have these effects has been almost totally ignored. This book sets out to describe not only how, in terms of pharmacology or psychopharmacology, but more importantly why plant- and fungus-derived chemicals have their effects on the human brain. The answer to this last question resides, in part, with the terrestrial world's two dominant life forms, the plants and the insects, and the many ecological roles the 'secondary metabolite' plant chemicals are trying to play; for instance, defending the plant against insect herbivores whilst attracting insect pollinators. The answer also resides in the intersecting genetic heritage of mammals, plants, and insects and the surprising biological similarities between the three taxa. In particular it revolves around the close correspondence between the brains of insects and humans, and the intercellular signaling pathways shared by plants and humans. Plants and the Human Brain describes and discusses both how and why phytochemicals affect brain function with respect to the three main groups of secondary metabolites: the alkaloids, which provide us with caffeine, a host of poisons, a handful of hallucinogens, and most drugs of abuse (e.g. morphine, cocaine, DMT, LSD, and nicotine); the phenolics, including polyphenols, which constitute a significant and beneficial part of our natural diet; and the terpenes, a group of multifunctional compounds which provide us with the active components of cannabis and a multitude of herbal extracts such as ginseng, ginkgo and valerian.

Download or read book The Emerald Planet written by David Beerling and published by Oxford University Press. This book was released on 2017-05-12 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants have profoundly moulded the Earth's climate and the evolutionary trajectory of life. Far from being 'silent witnesses to the passage of time', plants are dynamic components of our world, shaping the environment throughout history as much as that environment has shaped them. In The Emerald Planet, David Beerling puts plants centre stage, revealing the crucial role they have played in driving global changes in the environment, in recording hidden facets of Earth's history, and in helping us to predict its future. His account draws together evidence from fossil plants, from experiments with their living counterparts, and from computer models of the 'Earth System', to illuminate the history of our planet and its biodiversity. This new approach reveals how plummeting carbon dioxide levels removed a barrier to the evolution of the leaf; how plants played a starring role in pushing oxygen levels upwards, allowing spectacular giant insects to thrive in the Carboniferous; and it strengthens fascinating and contentious fossil evidence for an ancient hole in the ozone layer. Along the way, Beerling introduces a lively cast of pioneering scientists from Victorian times onwards whose discoveries provided the crucial background to these and the other puzzles. This understanding of our planet's past sheds a sobering light on our own climate-changing activities, and offers clues to what our climatic and ecological futures might look like. There could be no more important time to take a close look at plants, and to understand the history of the world through the stories they tell. Oxford Landmark Science books are 'must-read' classics of modern science writing which have crystallized big ideas, and shaped the way we think.
Download or read book Urban Evolutionary Biology written by Marta Szulkin and published by Oxford University Press. This book was released on 2020-05-05 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban Evolutionary Biology fills an important knowledge gap on wild organismal evolution in the urban environment, whilst offering a novel exploration of the fast-growing new field of evolutionary research. The growing rate of urbanization and the maturation of urban study systems worldwide means interest in the urban environment as an agent of evolutionary change is rapidly increasing. We are presently witnessing the emergence of a new field of research in evolutionary biology. Despite its rapid global expansion, the urban environment has until now been a largely neglected study site among evolutionary biologists. With its conspicuously altered ecological dynamics, it stands in stark contrast to the natural environments traditionally used as cornerstones for evolutionary ecology research. Urbanization can offer a great range of new opportunities to test for rapid evolutionary processes as a consequence of human activity, both because of replicate contexts for hypothesis testing, but also because cities are characterized by an array of easily quantifiable environmental axes of variation and thus testable agents of selection. Thanks to a wide possible breadth of inference (in terms of taxa) that may be studied, and a great variety of analytical methods, urban evolution has the potential to stand at a fascinating multi-disciplinary crossroad, enriching the field of evolutionary biology with emergent yet incredibly potent new research themes where the urban habitat is key. Urban Evolutionary Biology is an advanced textbook suitable for graduate level students as well as professional researchers studying the genetics, evolutionary biology, and ecology of urban environments. It is also highly relevant to urban ecologists and urban wildlife practitioners.

Download or read book Conservation Physiology written by Christine L. Madliger and published by Oxford University Press, USA. This book was released on 2020 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation physiology is a rapidly expanding, multidisciplinary field that utilizes physiological knowledge and tools to understand and solve conservation challenges. This novel text provides the first consolidated overview of its scope, purpose, and applications, with a focus on wildlife. It outlines the major avenues and advances by which conservation physiology is contributing to the monitoring, management, and restoration of wild animal populations. This book also defines opportunities for further growth in the field and identifies critical areas for future investigation. By using a series of global case studies, contributors illustrate how approaches from the conservation physiology toolbox can tackle a diverse range of conservation issues including the monitoring of environmental stress, predicting the impact of climate change, understanding disease dynamics, improving captive breeding, and reducing human-wildlife conflict. Moreover, by acting as practical road maps across a diversity of sub-disciplines, these case studies serve to increase the accessibility of this discipline to new researchers. The diversity of taxa, biological scales, and ecosystems highlighted illustrate the far-reaching nature of the discipline and allow readers to gain an appreciation for the purpose, value, applicability, and status of the field of conservation physiology. Conservation Physiology is an accessible supplementary textbook suitable for graduate students, researchers, and practitioners in the fields of conservation science, eco-physiology, evolutionary and comparative physiology, natural resources management, ecosystem health, veterinary medicine, animal physiology, and ecology.
