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.

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.

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.

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.

Phylogenomics: A Primer, Second Edition is for advanced undergraduate and graduate biology students studying molecular biology, comparative biology, evolution, genomics, and biodiversity. This book explains the essential concepts underlying the storage and manipulation of genomics level data, construction of phylogenetic trees, population genetics, natural selection, the tree of life, DNA barcoding, and metagenomics. The inclusion of problem-solving exercises in each chapter provides students with a solid grasp of the important molecular and evolutionary questions facing modern biologists as well as the tools needed to answer them.

In paleoanthropology the group of hominids known as the "robust" australopithecines has emerged as one of the most interesting. Through them we have the opportunity to examine the origin, natural history, and ultimate extinction of not just a single species, but of an entire branch in the hominid fossil record.

It is generally agreed that the human lineage can be traced back to this group of comparatively small-brained, large-toothed creatures. This volume focuses on the evolutionary history of these early hominids with state-of-the-art contributions by leading international authorities in the field. Although a case can be made for a "robust" lineage, the functional and taxonomic implications of the morphological features are subject to vigorous disagreement. An area of lively debate is the possible causal relationship between the presence of early Homo and the origin, evolution, and virtual extinction of "robust" australopithecines.

This volume summarizes what has been learned about the evolutionary history of the "robust" australopithecines in the 50 years since Robert Broom first encountered the visage of a new kind of ape-man from Kromdraai. New discoveries from Kromdraai to Lomekwi have served to keep us aware that the paleontological record for hominid evolution is hardly exhausted. Because of such finds no single volume can hope to stand as a summary on the "robust" australopithecines for very long, but this classic volume comes close to achieving this goal. The book sheds new light upon some old questions and also acts to provide new questions. The answers to those questions bring us closer to a fuller understanding and appreciation of the origins, evolution, and ultimate demise of the "robust" australopithecines.

Since the "robust" australopithecines most likely stand as our closest relatives, a better understanding of their origin, history, and demise serves to provide heightened appreciation of the course of human evolution itself. This definitive volume addresses the questions and problems surrounding this important lineage.

Evolutionary Medicine is based upon the view that many contemporary social, psychological, and physical illnesses are related to an incompatability between current human lifestyles and environments and the conditions under which human biology developed. This book, featuring contributions from many of the leading workers in this devloping area, provides a good introduction and overview to this emerging field.

All animals and plants form associations with hundreds or thousands of different beneficial microorganisms. These symbiotic microbes play an important role in the development, adaptation, health and evolution of their hosts. This book brings together a group of diverse biologists to discuss microbial interactions with multicellular life forms including insects, corals, plants, and mammals, including humans. The various mechanisms by which microorganisms benefit their hosts are discussed, including providing essential nutrients, preventing disease, inducing the immune system, and combating stress. Since the microbiota can be transferred from parent to offspring, it plays an important role in the origin and evolution of animal and plant species. This book should be of interest to the widest range of biological scientists, merging the studies of host and microbial physiology, symbiosis, and the ecology and evolution of symbiotic partners.

Following centuries of debate about "nature and nurture" the discovery of DNA established the idea that nature (genes) determines who we are, relegating nurture (environment) to icing on the cake. Since the 1950s, the new science of epigenetics has demonstrated how cellular environments and certain experiences and behaviors influence gene expression at the molecular level, with significant implications for health and wellbeing. To the amazement of scientists, mapping the human genome indirectly supported these insights. Anthropologists Margaret Lock and Gisli Palsson outline vituperative arguments from Classical times about the relationship between nature and nurture, furthered today by epigenetic findings and the demonstration of a "reactive genome." The nature/nurture debate, they show, can never be put to rest, because these concepts are in constant flux in response to the new insights science continually offers.

These original contributions on the evolution of primates and the techniques for studying the subject cover an enormous range of material and incorporate the work of specialists from many different fields, showing the necessity of a multidisciplinary approach to problems of primate morphology and phylogeny. Collectively, they demonstrate the concerns and methods of leading contemporary workers in this and related fields. Each contributor shows his way of attacking fundamental problems of evolutionary primatology.The range of findings in this book include new clues to the evolution of the middle ear and the subsistence behavior of early primates, a persuasive critique of the Smith-Jones hypothesis that many features of primate cranial morphology are adaptations to the special vicissitudes of arboreal habitation, the remarkable association of relative muscle mass in the hands and feet of catarrhine primates with the particularities of prehensile behaviors, the wealth of behavioral data that may be obtained by the concentrated study of certain primates in the vicinity of waterholes, the striking differences between inferences about the same behavioral phenomena that are based on long-term as opposed to short-term observations of one primate social group, and the strategy of sophisticated mathematical techniques for elucidating biomechanical, evolutionary, and behavioral problems.Each chapter conveys the status and progress of research in these and other particular areas of special interest, pointing the way toward further clarification of the functional biology and phylogeny of primates through the application of relatively new techniques or the comprehensive employment of available methods. No attempt is made to smooth over controversial points of view, or to endorse a single uniform model of primate evolution. This work will be an important reference for evolutionary and physical anthropologists, evolutionary biologists, comparative morphologists, human anatomists, behavioralists, and students of evolution.

From two of the world's leading authorities on dogs, an imaginative journey into a future of dogs without people What would happen to dogs if humans simply disappeared? Would dogs be able to survive on their own without us? A Dog's World imagines a posthuman future for dogs, revealing how dogs would survive-and possibly even thrive-and explaining how this new and revolutionary perspective can guide how we interact with dogs now. Drawing on biology, ecology, and the latest findings on the lives and behavior of dogs and their wild relatives, Jessica Pierce and Marc Bekoff-two of today's most innovative thinkers about dogs-explore who dogs might become without direct human intervention into breeding, arranged playdates at the dog park, regular feedings, and veterinary care. Pierce and Bekoff show how dogs are quick learners who are highly adaptable and opportunistic, and they offer compelling evidence that dogs already do survive on their own-and could do so in a world without us. Challenging the notion that dogs would be helpless without their human counterparts, A Dog's World enables us to understand these independent and remarkably intelligent animals on their own terms.

The names given to the variety of man-like fossils known to scientists should reflect no more than scientific views of the nature of human evolution. However, often in the past these names have also reflected confusion regarding the basic principles of scientific nomenclature; and the matter has been further complicated by the many new finds of recent decades. It is the unique purpose of this book to clarify the present state of knowledge regarding the main lines of human evolution by expressing what is known (and what is surmised) about them in appropriate taxonomic language.

The papers in this volume were prepared by the world's leading authorities on the subject, and were revised in the light of discussions at a remarkable conference held in Austria in 1962 under the auspices of the Wenner-Gren Foundation. The authors review first the meaning of taxonomic statements as such, and then consider the substance of our present knowledge regarding the number and characteristics of species among living and extinct primates, including man and his ancestors. They also examine the relationship of behavior changes and selection pressures in evolutionary sequences.

Ample illustrations, bibliographies and an index enhance the permanent reference value of the book, which will undoubtedly prove to be among the fundamental paleoanthropological works of our time.

The Anthropocene defines the here-and-now time period on Earth of indelible (and possibly irreversible) human disturbance to the natural world, from habitat destruction and mass extinction to global climate change. To ameliorate and repair the damage that threatens the world's dwindling resources and our very existence, humanity is enacting massive interventions to fuse modern technologies with long established natural processes. Advances in genetic engineering have put us on the cusp of directly shaping the DNA of every living organism (including ourselves), as well as determining the evolution of completely novel species. The author invites the reader to explore how humans have manipulated the ancient forces of evolution and the future possibilities of genetic engineering for conservation and rewilding, de-extinction, and even the creation of viable populations of entirely new species. To entertain such possibilities of synthetic biology, he forces us to wrestle with the threats and ethical conundrums that surround the unintended consequences, as well as the values that humanity places on authenticity in nature. In so doing, this accessible and thought-provoking book explores the potential future of life on planet Earth.

The twenty-first century presents an increasing number of environmental problems, including toxic pollution, global warming, destruction of tropical forests, extinction of biological diversity, and depletion of natural resources. These environmental problems are generally due to human behavior, namely over-consumption of resources and overpopulation. Designing effective policies to address these problems requires a deep understanding of human behavior as well as ecology. This in turn requires considerations of human nature, and the evolutionary "design" of the human mind.
Evolutionary research on human behavior has profound implications for the environmental sciences. The aim of this collection is to bring together a variety of chapters that show how and why. Part 1, "Human Nature and Resource Conservation," addresses environmental problems from different evolutionary perspectives. Part 2, "The Ecological Noble Savage Hypothesis," examines the notion that our environmental problems are due to Western culture, and that our ancestors and people in indigenous societies lived in harmony with nature until the corrupting influences of Western culture. Part 3, "The Tragedy of the Commons," explores the conservation of common-pool or open-access natural resources, such as fisheries, forests, grazing lands, freshwater, and clean air. Part 4, "The Evolution of Discounting and Conspicuous Consumption," looks at the problem of explaining why people are so ecologically short-sighted and why people in developed countries consume so many resources. Part 5, "Overpopulation and Fertility Declines," addresses the evolution of human reproductive decisions. Part 6, "Biophilia," aims to explain why people cherish nature as well as destroy it.
The goal of this volume is to introduce environmental thinkers to evolutionary perspectives on human behavior, and the new interdisciplinary sciences of evolutionary psychology and behavioral ecology. This reader aims to help bridge the artificial division between the biological and social sciences, and provide a synthesis between evolutionary sciences of human behavior and environmental sciences.

Evolutionism and Its Critics is a critical history of evolutionary theories in the social sciences and a defense of them against their many critics. Sanderson deconstructs not only the wide array of social evolutionary theories, but the criticisms of the antievolutionists. Deconstructing evolutionary theories means laying bare their fundamental epistemological, methodological, conceptual, and theoretical assumptions and principles. Deconstructing antievolutionism means showing just where and how the critics have, for the most part, gone wrong. But Evolutionism and Its Critics aims to reconstruct as well as deconstruct and does this by building, on the shoulders of past giants of evolutionary theorizing, a comprehensive evolutionary interpretation of human society based on abundant scientific and historical evidence.

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.
