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.
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."
The threespine stickleback is a small fish of temperate coastal and fresh waters that exhibits extraordinary phenotypic diversity. Benefiting from its amenability to observation in the field and manipulation in the laboratory, Niko Tinbergen pioneered the threespine stickleback's use in behavioral studies and established it as a model system in ethology. This up-to-date volume incorporates reviews from active researchers who use studies of the fish to address a broad variety of evolutionary issues, including optimal foraging, armor variation, speciation, and the endocrine basis for correlated behavioral characters. The work demonstrates the value of viewing the biology of a single organism simultaneously from multiple perspectives. Students and researchers in ecology, evolution, animal behavior, and vertebrate zoology will find much of interest in this useful book.
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.
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,
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.
Evolutionary psychiatry attempts to explain and examine the development and prevalence of psychiatric disorders through the lens of evolutionary and adaptationist theories. In this edited volume, leading international evolutionary scholars present a variety of Darwinian perspectives that will encourage readers to consider 'why' as well as 'how' mental disorders arise. Using insights from comparative animal evolution, ethology, anthropology, culture, philosophy and other humanities, evolutionary thinking helps us to re-evaluate psychiatric epidemiology, genetics, biochemistry and psychology. It seeks explanations for persistent heritable traits shaped by selection and other evolutionary processes, and reviews traits and disorders using phylogenetic history and insights from the neurosciences as well as the effects of the modern environment. By bridging the gap between social and biological approaches to psychiatry, and encouraging bringing the evolutionary perspective into mainstream psychiatry, this book will help to inspire new avenues of research into the causation and treatment of mental disorders.
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.
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.
Anyone interested in comparative biology or the history of science will find this myth-busting work genuinely fascinating. It draws attention to the seminal studies and important advances that have shaped systematic and biogeographic thinking. It traces concepts in homology and classification from the 19th century to the present through the provision of a unique anthology of scientific writings from Goethe, Agassiz, Owen, Naef, Zangerl and Nelson, among others.
Nine chapters on diverse topics that include: an analysis of whether sociobiology has killed ethology or revitalized it; aims, limitations, and the future of ethology and comparative ethology; the tyranny of anthropocentrism; psychoimmunology; gender differences in behavior; behavioral development.
We have come a long way towards better understanding how new species originate, i.e. speciation, which long remained Darwin's "mystery of mysteries." Since speciation is the underlying mechanism for radiations, it is the ultimate causation for the biological diversity of life that surrounds us. Without a doubt, Charles Darwin's contribution to our understanding of the origin of biodiversity cannot be overestimated. This book is a contribution to both the Darwin Year we celebrated in 2009 and to the Year of Biodiversity and Conservation 2010. The studies and model cases presented show the progress and dynamics of research based on Darwinian theories and sheds light on its implications in the context of current biodiversity crises. The great importance of adaptive (and non-adaptive) radiations for biodiversity is widely accepted, but our understanding of the processes and mechanisms involved is still limited and generalizations need to be based on the accumulation of more evidence from additional case studies. The studies presented in this volume are those urgently needed and focus on a variety of organisms and different aspects of radiations. The scientific results presented therein are excellent examples not only of evolution in action, but also of active research on evolutionary processes and their most apparent outcome -- biodiversity.
Soon to be a major motion picture
Newborn mammals can weigh as little as a dime or as much as a motorcycle. Some receive milk for only a few days, whereas others nurse for years. Humans typically have only one baby at a time following nine months of pregnancy, but other mammals have twenty or more young after only a few weeks in utero. What causes this incredible reproductive diversity? In Reproduction in Mammals, Virginia Hayssen and Teri Orr present readers with a fascinating examination of the varied reproductive strategies of a broad spectrum of mammals, from marsupials to whales. This unique book's comprehensive coverage gathers stories from many taxa into a single, cohesive perspective that centers on the reproductive lives of females. The authors shed light on a number of intriguing questions, including * do bigger moms have bigger babies?* do primates have longer pregnancies than other groups?* does habitat influence animals' reproductive patterns?* do carnivores typically produce larger litters than prey species? The book opens with the authors' definition of what constitutes a female perspective and an examination of the evolution of reproduction in mammals. It then outlines the typical individual mammalian female: her genetics, anatomy, and physiology. Taking a nuanced approach, Hayssen and Orr describe the female reproductive cycle and explore female mammals' interactions with males and offspring. Readers will come away from this thought-provoking book with an understanding not only of how reproduction fits into the lives of female mammals but also of how biology has affected the enormously diverse reproductive patterns of the phenotypes we observe today.
Our knowledge of our solar system has passed the point of no return. Increasingly, it seems possible that scientists will soon discover how life is created on habitable planets like Earth and Mars. Scientists have responded to a renewed public interest in the origin of life with research, but many questions still remain unanswered in the broader conversation. Other questions can be answered by the laws of chemistry and physics, but questions surrounding the origin of life are best answered by reasonable extrapolations of what scientists know from observing the Earth and its solar system. Origin of Life: What Everyone Needs to Know (R) is a comprehensive scientific guide on the origin of life. David W. Deamer sets out to answer the top forty questions about the origin of life, including: Where do the atoms of life come from? How old is Earth? What was the Earth like before life originated? Where does water come from? How did evolution begin? After he provides the informational answer for each question, there is a follow-up: How do we know? This question expands the horizon of the whole book, and provides scientific reasoning and explanations for hypotheses surrounding the origin of life. How scientists come to their conclusions and why we can trust these answers is an important question, and Deamer provides answers to each big question surrounding the origin of life, from what it is to why we should be curious.
An extremely well-organized, conceptually clear, empirically informed, and carefully argued volume...What makes this contribution special is the invigorating infusion of a wealth of principles and knowledge derived from evolutionary biology, neurophysiology, and cognitive science...The chapters provide abundant material for animated discussion.'' --- Evolution and Human Behavior, September 1997 When engaging in laboratory and field studies, researchers have an extensive set of implicit assumptions that justifies their research. However, these assumptions are rarely made explicit either to the researchers themselves, to their colleagues, or to the public. In this fascinating volume, the author gives insight into these underlying beliefs that scientists have regarding moral and biological issues involved in human life-such as decisions that influence reproductive practices, the termination of life, and the pursuit of biomedical research. He then uses this descriptive base to develop an ethic based on rational liberalism. His arguments stem from the thinking of biologists, moral philosophers, cognitive scientists, and social and developmental psychologists. |
