Offering coverage of a wide range of topics on snake reproduction and phylogeny, this comprehensive book discusses everything from primordial germ migration in developing embryos to semelparity (death after reproduction) in the aspic viper. Beginning with a review of the history of snake reproductive studies, it presents new findings on development, placentation, spermatogenesis, male and female reproductive anatomy, hormonal control of reproduction, reproductive cycles, sex pheromones, and parental care. An indispensible reference, this book offers comparative chapters on snake phylognetics examining morphological characteristics alongside strictly molecular concerns. It is rife with illustrations and color plates.

Researchers now recognize that above- and belowground communities are indirectly linked to one another, often by plant-mediated mechanisms. To date, however, there has been no single multi-authored edited volume on the subject. This book remedies that gap, and offers state-of-the art insights into basic and applied research on aboveground-belowground interactions and their functional consequences. Drawing on a diverse pool of global expertise, the authors present diverse approaches that span a range of scales and levels of complexity. The respective chapters provide in-depth information on the current state of research, and outline future prospects in the field of aboveground-belowground community ecology. In particular, the book's goal is to expand readers' knowledge of the evolutionary, community and ecosystem consequences of aboveground-belowground interactions, making it essential reading for all biologists, graduate students and advanced undergraduates working in this rapidly expanding field. It touches on multiple research fields including ecology, botany, zoology, entomology, microbiology and the related applied areas of biodiversity management and conservation.

The Vertebrata is one of the most speciose groups of animals, comprising more than 58,000 living species. This book provides a detailed account on the comparative anatomy, development, homologies and evolution of the head, neck, pectoral and forelimb muscles of vertebrates. It includes hundreds of illustrations, as well as numerous tables showing the homologies between the muscles of all the major extant vertebrate taxa, including lampreys, elasmobranchs, hagfish, coelacanths, dipnoans, actinistians, teleosts, halecomorphs, ginglymodians, chondrosteans, caecilians, anurans, urodeles, turtles, lepidosaurs, crocodylians, birds, and mammals such as monotremes, rodents, tree-shrews, flying lemurs and primates, including modern humans. It also provides a list of more than a thousand synonyms that have been used by other authors to designate these muscles in the literature. Importantly, it also reviews data obtained in the fields of evolutionary developmental biology, molecular biology and embryology, and explains how this data helps to understand the evolution and homologies of vertebrate muscles. The book will useful to students, teachers, and researchers working in fields such as functional morphology, ecomorphology, evolutionary developmental biology, zoology, molecular biology, evolution, and phylogeny. As the book includes crucial information about the anatomy, development, homologies, evolution and muscular abnormalities of our own species, Homo sapiens, it will also be helpful to physicians and medical students.

In most habitats, adaptations are the single most obvious aspects of an organisma (TM)s phenotype. However, the most obvious feature of many subterranean animals are losses, not adaptations. Even Darwin saw subterranean animals as degenerates: examples of eyelessness and loss of structure in general. For him, the explanation was a straightforward Lamarckian one, and one that did not involve adaptation and the struggle of existence. This volume is a comprehensive account of all known species of subterranean fishes. It includes an extensive introduction, history of investigations, consideration of non-stygobitic fishes in caves, and detailed analysis of the conservation status of these very rare animals.

The Metaphysical Society was founded in 1869 at the instigation of James Knowles (editor of the Contemporary Review and then of the Nineteenth Century) with a view to 'collect, arrange, and diffuse Knowledge (whether objective or subjective) of mental and moral phenomena' (first resolution of the society in April 1869). The Society was a private dining and debate club that gathered together a latter-day clerisy. Building on the tradition of the Cambridge Apostles, they elected talented members from across the Victorian intellectual spectrum: Bishops, one Cardinal, philosophers, men of science, literary figures, and politicians. The Society included in its 62 members prominent figures such as T. H. Huxley, William Gladstone, Walter Bagehot, Henry Edward Manning, John Ruskin, and Alfred Lord Tennyson. The Metaphysical Society (1869-1880) moves beyond Alan Willard Brown's 1947 pioneering study of the Metaphysical Society by offering a more detailed analysis of its inner dynamics and its larger impact outside the dining room at the Grosvenor Hotel. The contributors shed light on many of the colourful figures that joined the Society as well as the alliances that they formed with fellow members. The collection also examines the major concepts that informed the papers presented at Society meetings. By discussing groups, important individuals, and underlying concepts, the volume contributes to a rich, new picture of Victorian intellectual life during the 1870's, a period when intellectuals were wondering how, and what, to believe in a time of social change, spiritual crisis, and scientific progress.

This volume provides individual treatments of the major molluscan taxa. Each chapter provides an overview of the evolution, phylogeny and classification of a group of molluscs, as well as more specific and detailed coverage of their biology (reproduction, feeding and digestion, excretion, respiration etc.), their long fossil record and aspects of their natural history. The book is illustrated with hundreds of colour figures. In both volumes, concepts are summarised in colour-coded illustrations. Key selling features: Comprehensively reviews molluscan biology and evolutionary history Includes a description the anatomy and physiology of anatomical systems Up to date treatment with a comprehensive bibliography Reviews the phylogenetic history of the major molluscan lineages

The field of molecular evolution has experienced explosive growth in recent years due to the rapid accumulation of genetic sequence data, continuous improvements to computer hardware and software, and the development of sophisticated analytical methods. The increasing availability of large genomic data sets requires powerful statistical methods to analyse and interpret them, generating both computational and conceptual challenges for the field.
Computational Molecular Evolution provides an up-to-date and comprehensive coverage of modern statistical and computational methods used in molecular evolutionary analysis, such as maximum likelihood and Bayesian statistics. Yang describes the models, methods and algorithms that are most useful for analysing the ever-increasing supply of molecular sequence data, with a view to furthering our understanding of the evolution of genes and genomes. The book emphasizes essential concepts rather than mathematical proofs. It includes detailed derivations and implementation details, as well as numerous illustrations, worked examples, and exercises. It will be of relevance and use to students and professional researchers (both empiricists and theoreticians) in the fields of molecular phylogenetics, evolutionary biology, population genetics, mathematics, statistics and computer science. Biologists who have used phylogenetic software programs to analyze their own data will find the book particularly rewarding, although it should appeal to anyone seeking an authoritative overview of this exciting area of computational biology.

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.

This book delves into one of the greatest riddles perplexing modern science: Why are humans so smart? In a format understandable even by the non-expert, the author investigates the origins of human intelligence, starting with classical Darwinian concepts. Thus, the strengths and beauty of natural selection are presented with many examples taken from natural history. Common criticisms of Darwin, from scientists and non-scientists alike, are confronted and shown to be either inconclusive or outright false. The author then launches into a discussion of human intelligence, the most important feature of human evolution, and how it cannot be fully explained by mutational selection. Modern humans are smarter than what is demanded by our evolutionary experience as hunter-gatherers. The difficulty lies in the inability of natural selection to answer the following question: how can a complex set of genes, controlling expensive traits with little immediate benefit, come into permanent existence within a short time period in every member of a small population (which was dispersed and geographically isolated over a huge planet) which had a low reproductive output and a low mutation rate? The book concludes with a speculative epigenetic theory of intelligence that does not require DNA mutations as a source of evolution. Although the book is comprehensible by anyone with a college education, this last section in particular should intrigue both layman and expert alike.

In the 17th century, Descartes put forth the metaphor of the machine to explain the functioning of living beings. In the 18th century, La Mettrie extended the metaphor to man. The clock was then used as the paradigm of the machine. In the 20th century, this metaphor still held but the clock was replaced by a computer.

Nowadays, the organism is viewed as a robot obeying signals emanating from a computer program controlled by genetic information. This book shows that such a conception leads to contradictions not only in the theory of biology but also in its experimental research program, thereby impeding its development.

The analysis of this problem is based on the most recent experimental data obtained in molecular biology as well as the history and philosophy of biology. It shows that the machine theory did not succeed in breaking with Aristotles finalism.

The book presents a new approach to biological systems based on cellular Darwinism. Genes are ruled by probabilistic mechanisms allowing cells to differentiate stochastically. Embryo development is not governed by a determinist genetic program but by natural selection occurring among cell populations inside the organism.

This theory has considerable philosophical consequences. Man may be a machine but he is a random one.

Genetic differences in humans, like those between individuals of any animal or plant species and those between species, are all products of the evolutionary development of the living world. Th ese diff erences, with their behavioral consequences, can only be understood in the light of evolution. Our understanding of evolution, however, has itself evolved. Th e Darwin-Wallace theory of evolution appeared in the nineteenth century. Since then, development of evolutionary thought has gone through several stages. Th e contributions in this volume describe those stages.

The first four decades after Darwin were dominated by studies in comparative anatomy, embryology, systematics, zoogeography, phytogeography, and paleontology, all intended to discover and examine the evidences of evolution. But the phylogenies of the animal and plant kingdoms, that is, the history of the linkages of animal and plant organisms as they change through time, were less well documented. In particular, the phylogeny of humans is still not completely known.

The period following World War Two saw acceleration of activity in fi elds in and bordering on behavioral genetics. Research in neuroendocrinology showed that higher cortical centers could infl uence and be infl uenced by the hypothalamus, pituitary, thyroid, adrenals, and gonads. Genetic diversity in the function of these organs had obvious consequences for social and cultural behavior. Th e failure of some early and long-reinforced attempts at conditioning by students of comparative animal behavior showed species-specifi c innate behavior could not be ignored in any theory that attempts to combine psychology and anthropology. Th is classic volume summarizes the development of evolutionary thinking, and describes how what we know about genetic diversity links up with research on human behavior.

"J. N. Spuhler" was known for his pioneering work in the department of anthropological genetics. He taught in many universities including Ohio State University, the University of Michigan, and the University of Mexico. He received the National Academy of Science award for scientific reviewing and his work has appeared in scholarly journals including: "Journal of Anthropological Research, Annual Review of Anthropology," and "American Journal of Physical Anthropology."

Although his name has become a household word after he published "The Origin of the Species," a one-volume edition of his writings that covers the full gamut of his theoretical as well as scientific writings has not been available for many years. "Charles Darwin: An Anthology," covers the heart of the five books for which the author is best known. This readable volume includes "The Autobiography, The Voyage of the Beagle, The Origin of the Species, The Descent of Man," and "The Expression of the Emotion."

The volume also includes parts of Darwin's less well-known works. Although it was published last chronologically, "The Autobiography" is an ideal beginning to the volume. A new introduction by the noted anthropologist Lionel Tiger underlines the continuing importance of Darwin's thinking, and explains why it still infl uences contemporary scholarship in many fi elds.

These selections have not been rewritten--they are pure Darwin. The dull and the unessential have been eliminated. What remains is material that best illustrates Darwin's most important and interesting ideas. Th e selection manages as well to retain his most readable prose, while presenting the fundamentals of Darwin's revolutionary thought. Collectively, the volume paints a picture of an immensely curious and indefatigable mind. This volume also includes a critical bibliography that will prove valuable to those interested in further reading.

Neanderthals in the Classroom examines the ongoing battle surrounding evolution from a cultural and historical perspective and then puts Theodosius Dobzhansky's claim that "nothing in biology makes sense except in the light of evolution" to the ultimate test by exploring the potential evolutionary roots of this societal and educational clash over human origins. In examining the biological roots of the conflict, Watts demonstrates how understanding our inner Neanderthal allows us to consciously choose more highly evolved forms of communication as a means of alleviating societal division and creating space for more effective science education. Key Features: Introduces readers to the multifaceted world of evolution education. Describes the complex interplay between religious beliefs and science as well as the clash of false information and formal education. Offers an overview of the transformation of public opinion of evolution and science over time in the United States due to the perceived conflict between science and religion. Examines students' misconceptions about the theory of evolution and the general nature of scientific discovery due to the contradictory messages that they receive in popular culture. Offers potential means to amend misconceptions so that students and other individuals can integrate evolutionary theory into their worldviews, regardless of their religious background.

Recent advances that allow scientists to quickly and accurately sequence a genome have revolutionized our view of the structure and function of genes as well as our understanding of evolution. A new era of genetics is underway, one that allows us to fully embrace Dobzhansky's famous statement that "Nothing in biology makes sense except in the light of evolution". Genetics: Genes, Genomes, and Evolution presents the fundamental principles of genetics and molecular biology from an evolutionary perspective as informed by genome analysis. By using what has been learned from the analyses of bacterial and eukaryotic genomes as its basis, the book unites evolution, genomics, and genetics in one narrative approach. Genomic analysis is inherently both molecular and evolutionary, and every chapter is approached from this unified perspective. Similarly, genomic studies have provided a deeper appreciation of the profound relationships between all organisms - something reflected in the book's integrated discussion of bacterial and eukaryotic evolution, genetics and genomics. It is an approach that provides students with a uniquely flexible and contemporary view of genetics, genomics, and evolution.

Living things are constantly engaged in a struggle for existence, and ingenious devices for the purpose of self-preservation can be seen in all types of animal and plant life. However, nature also displays phenomena that are not related to survival or that seem clearly to violate the principle of self-preservation--particularly when organisms interact with one another. Darwin investigated these apparent contradictions and proposed that both mechanisms of self preservation and those of reproduction are explained by a more basic principle of "natural selection"--the reproductive survival of the fittest. George C. Williams in "Group Selection" challenges the adequacy of this process of selection at the individual level.

Williams has here collected the work of the chief partisans with opposed viewpoints on the theory of selection at the group level to state their arguments and rebuttals. A minority of modern biologists offer evidence to show that groups of living things are organized to assure their collective survival; they are not merely collections of individuals designed for their own survival and reproduction. In opposition, defenders of the traditional point of view charge that mechanisms of group survival are based on illusion and misinterpretation.

Because of the wide range of opinion expressed in "Group Selection," the reader is exposed to all sides of the dispute and encouraged to form his or her own views. In addition, as a source book on current evolutionary issues or for research or reference material, "Group Selection" remains a valuable addition to every personal and institutional library in the biological sciences.

"George C. Williams" is professor emeritus of biological sciences at the State University of New York at Stony Brook. He is the author of "Adaptation and Natural Selection" and has contributed numerous articles to scholarly publications on the behavior and ecology of fish and has published several technical articles on evolutionary mechanisms, especially in relation to social behavior, strategies of reproduction, and adaptive features of life cycles. He is a member of the National Academy of Sciences and was awarded its Elliot Medal.

Offers an original and fertile way to integrate spiritual and scientific views of human evolution. It offers a new and refreshing alternative to the way we think about our origins: random mutation (mechanistic neo-Darwinism), Genesis (God did it all personally), and Intelligent Design (God personally does what we can't otherwise account for). The result is an invigorating perspective on how our best qualities -- our capacity for love, our appreciation of beauty, our altruistic capability, our creativity and intelligence -- have come into being and evolved. How we think about our origin matters: if we think we are machines living among other machines, we will act accordingly. By showing evolution as a creative and intelligent process with its own inherent logic, THE ORIGIN OF HUMAN NATURE resolves the dilemma of how to have, at the same time, both truth and ethics. Instead of starting in an imagined remote and 'uncertain past' and moving to the present, this book starts at the certain and 'immediate present' and works back. That consciousness, creativity, and intelligence exist is certain. The question is: how can these have evolved? Dr Albert Low has made a study of human nature throughout his life. To write this book he draws on his prolonged meditations on creativity and the human condition, his years of providing psychological and spiritual counseling, and a wide-ranging knowledge of Western psychology, philosophy, and science.

This title was first published in 2000: Complex Life argues for the importance of the new perspective of non modern social theory in understanding human agency. Darwinian natural selection theory and complexity theory are used to provide new insights into human origins, mind and culture. Through bringing these ideas together it is argued that nature and culture are inseparably linked within human agency and that in consequence it is time to transcend the limitations of both modern and postmodern social science. This book argues that nature has never been controlled or transcended. Humankind is instead an emerged outcome of the historical interweaving of the environment, morphology, mind and culture. This wide-ranging analysis offers new insights into human nature for anthropologists and sociologists interested in human evolution, social theory or human agency.
