Cryptic species are organisms which look identical, but which represent distinct evolutionary lineages. They are an emerging trend in organismal biology across all groups, from flatworms, insects, amphibians, primates, to vascular plants. This book critically evaluates the phenomenon of cryptic species and demonstrates how they can play a valuable role in improving our understanding of evolution, in particular of morphological stasis. It also explores how the recognition of cryptic species is intrinsically linked to the so-called 'species problem', the lack of a unifying species concept in biology, and suggests alternative approaches. Bringing together a range of perspectives from practicing taxonomists, the book presents case studies of cryptic species across a range of animal and plant groups. It will be an invaluable text for all biologists interested in species and their delimitation, definition, and purpose, including undergraduate and graduate students and researchers.

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.

A fully updated edition of one of the most original accounts of evolution ever written, featuring new fractal diagrams, six new 'tales' and the latest scientific developments. THE ANCESTOR'S TALE is a dazzling, four-billion-year pilgrimage to the origins of life: Richard Dawkins and Yan Wong take us on an exhilarating reverse journey through evolution, from present-day humans back to the microbial beginnings of life. It is a journey happily interrupted by meetings of fellow modern animals (as well as plants, fungi and bacteria) similarly tracing their evolutionary path back through history. As each evolutionary pilgrim tells their tale, Dawkins and Wong shed light on topics such as speciation, sexual selection and extinction. Written with unparalleled wit, clarity and intelligence; taking in new scientific discoveries of the past decade; and including new 'tales', illustrations and fractal diagrams, THE ANCESTOR'S TALE shows us how remarkable we are, how astonishing our history, and how intimate our relationship with the rest of the living world.

This volume reaches beyond the controversy surrounding the teaching and learning of evolution in the United States, specifically in regard to the culture, politics, and beliefs found in the Southeast. The editors argue that despite a deep history of conflict in the region surrounding evolution, there is a wealth of evolution research taking place-from biodiversity in species to cultural evolution and human development. In fact, scientists, educators, and researchers from around the United States have found their niche in the South, where biodiversity is high, culture runs deep, and the pace is just a little bit slower.

Fossil crinoids are exceptionally suited to deep-time studies of community paleoecology and niche partitioning. By merging ecomorphological trait and phylogenetic data, this Element summarizes niche occupation and community paleoecology of crinoids from the Bromide fauna of Oklahoma (Sandbian, Upper Ordovician). Patterns of community structure and niche evolution are evaluated over a ~5 million-year period through comparison with the Brechin Lagerstatte (Katian, Upper Ordovician). The authors establish filtration fan density, food size selectivity, and body size as major axes defining niche differentiation, and niche occupation is strongly controlled by phylogeny. Ecological strategies were relatively static over the study interval at high taxonomic scales, but niche differentiation and specialization increased in most subclades. Changes in disparity and species richness indicate the transition between the early-middle Paleozoic Crinoid Evolutionary Faunas was already underway by the Katian due to ecological drivers and was not triggered by the Late Ordovician mass extinction.

Evolution of Learning and Memory Mechanisms is an exploration of laboratory and field research on the many ways that evolution has influenced learning and memory processes, such as associative learning, social learning, and spatial, working, and episodic memory systems. This volume features research by both outstanding early-career scientists as well as familiar luminaries in the field. Learning and memory in a broad range of animals are explored, including numerous species of invertebrates (insects, worms, sea hares), as well as fish, amphibians, birds, rodents, bears, and human and nonhuman primates. Contributors discuss how the behavioral, cognitive, and neural mechanisms underlying learning and memory have been influenced by evolutionary pressures. They also draw connections between learning and memory and the specific selective factors that shaped their evolution. Evolution of Learning and Memory Mechanisms should be a valuable resource for those working in the areas of experimental and comparative psychology, comparative cognition, brain-behavior evolution, and animal behavior.

Recent interest in the evolution of the social contract is extended by providing a throughly naturalistic, evolutionary account of the biological underpinnings of a social contract theory of morality. This social contract theory of morality (contractevolism) provides an evolutionary justification of the primacy of a moral principle of maximisation of the opportunities for evolutionary reproductive success (ERS), where maximising opportunities does not entail an obligation on individuals to choose to maximise their ERS. From that primary principle, the moral principles of inclusion, individual sovereignty (liberty) and equality can be derived. The implications of these principles, within contractevolism, are explored through an examination of patriarchy, individual sovereignty and copulatory choices, and overpopulation and extinction. Contractevolism is grounded in evolutionary dynamics that resulted in humans and human societies. The most important behavioural consequences of evolution to contractevolism are reciprocity, cooperation, empathy, and the most important cognitive consequences are reason and behavioural modification.

Anti-scientific misinformation has become a serious problem on many fronts, including vaccinations and climate change. One of these fronts is the persistence of anti-evolutionism, which has recently been given a superficially professional gloss in the form of the intelligent design movement. Far from solely being of interest to researchers in biology, anti-evolutionism must be recognized as part of a broader campaign with a conservative religious and political agenda. Much of the rhetorical effectiveness of anti-evolutionism comes from its reliance on seemingly precise mathematical arguments. This book, the first of its kind to be written by a mathematician, discusses and refutes these arguments. Along the way, it also clarifies common misconceptions about both biology and mathematics. Both lay audiences and professionals will find the book to be accessible and informative.

With the emergence of the new field of evolutionary developmental biology we are witnessing a renaissance of Darwin s insights 150 years after his Origin of Species. Thus far, the exciting findings from evo-devo have only been trickling into college courses and into the domain of non-specialists. With its focus on the human organism, Quirks of Human Anatomy opens the floodgates by stating the arguments of evo-devo in plain English, and by offering a cornucopia of interesting case studies and examples. Its didactic value is enhanced by 24 schematic diagrams that integrate a host of disparate observations, by its Socratic question-and-answer format, and by its unprecedented compilation of the literature. By framing the hows of development in terms of the whys of evolution, it lets readers probe the deepest questions of biology. Readers will find the book not only educational but also enjoyable, as it revels in the fun of scientific exploration.

The newest addition to John Brockman's Edge.org series explores life itself, bringing together the world's leading biologists, geneticists, and evolutionary theorists-including Richard Dawkins, Edward O. Wilson, J. Craig Venter, and Freeman Dyson. Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come-and takes a brilliantly educated guess at where we're heading. Richard Dawkins and J. Craig Venter compare genes to digital information, and sketch the frontiers of genomic research. Edward O. Wilson reveals what ants can teach us about building a superorganism-and, in turn, about how cells build an organism. Elsewhere, David Haig reports new findings on how mothers and fathers individually influence the human genome, while Kary Mullis covers cutting edge treatments for dangerous viruses. And there's much more in this fascinating volume. We may never have all the answers. But the thinkers collected in Life are asking questions that will keep us dreaming for generations.

This book represents an effort to understand very old questions about biological form, function, and the relationships between them. The essays collected here reflect the diversity of approaches in evolutionary developmental biology (Evo Devo), including not only studies by prominent scientists whose research focuses on topics concerned with evolution and development, but also historically and conceptually oriented studies that place the scientific work within a larger framework and ask how it can be pushed further. Topics under discussion range from the use of theoretical and empirical biomechanics to understand the evolution of plant form, to detailed studies of the evolution of development and the role of developmental constraints on phenotypic variation. The result is a rich and interdisciplinary volume that will begin a wider conversation about the shape of Evo Devo as it matures as a field.

Mycorrhizae are mutualisms between plants and fungi that evolved over 400 million years ago. This symbiotic relationship commenced with land invasion, and as new groups evolved, new organisms developed with varying adaptations to changing conditions. Based on the author's 50 years of knowledge and research, this book characterizes mycorrhizae through the most rapid global environmental changes in human history. It applies that knowledge in many different scenarios, from restoring strip mines in Wyoming and shifting agriculture in the Yucatan, to integrating mutualisms into science policy in California and Washington, D.C. Toggling between ecological theory and natural history of a widespread and long-lived symbiotic relationship, this interdisciplinary volume scales from structure-function and biochemistry to ecosystem dynamics and global change. This remarkable study is of interest to a wide range of students, researchers, and land-use managers.

Group living is a widespread phenomenon amongst animals and has attracted considerable attention in a number of different contexts. This book focuses on the unifying concepts regarding group behaviour that have been developed over the last two decades. The authors discuss the mechanisms that govern the evolution and maintenance of grouping behaviour throughout the animal kingdom, and the factors that control observed group size and group composition in particular situations. Although the book's emphasis is on the elaboration of a conceptual framework, extensive examples and case studies illustrate the diversity of grouping phenomena across taxonomic boundaries, and demonstrate the general applicability of the concepts involved. Living in Groups will familiarize the reader with the latest ideas on the ecology and evolution of group-living animals, providing a summary and critical synthesis of the extensive and diverse literature on the subject.

'Packed with fresh and clear insights that will change the way you think about the world' Uri Gneezy 'One of those books that you pick up and then can't put down' Steve Stewart-Williams 'This is a book I will come back to again and again' Nichola Raihani How game theory - the ultimate theory of rationality - explains irrational behaviour. In Hidden Games, MIT economists Moshe Hoffman and Erez Yoeli find a surprising middle ground between the hyperrationality of classical economics and the hyper-irrationality of behavioural economics. They call it hidden games. Reviving game theory, Hoffman and Yoeli use it to explain our most puzzling behaviour, from the mechanics of Stockholm syndrome and internalised misogyny to why we help strangers and have a sense of fairness. Fun and powerfully insightful, Hidden Games is an eye-opening argument for using game theory to explain all the irrational things we think, feel, and do and will change how you think forever.

While plenty of entertaining books have been written about the history of alcohol and other intoxicants, none have offered a comprehensive, convincing answer to the basic question of why humans want to get high in the first place. Drunk elegantly cuts through the tangle of urban legends and anecdotal impressions that surround our notions of intoxication to provide the first rigorous, scientifically-grounded explanation for our love of alcohol. Drawing on evidence from archaeology, history, cognitive neuroscience, psychopharmacology, social psychology, literature, and genetics, Slingerland shows that our taste for chemical intoxicants is not an evolutionary mistake, as we are so often told. In fact, intoxication helps solve a number of distinctively human challenges: enhancing creativity, alleviating stress, building trust, and pulling off the miracle of getting fiercely tribal primates to cooperate with strangers. Our desire to get drunk, along with the individual and social benefits provided by drunkenness, played a crucial role in sparking the rise of the first large-scale societies. We would not have civilization without intoxication. From marauding Vikings and bacchanalian orgies to sex-starved fruit flies, blind cave fish, and problem-solving crows, Drunk is packed with fascinating case studies and engaging science, as well as practical takeaways for individuals and communities. The result is a captivating and long overdue investigation into humanity's oldest indulgence - one that explains not only why we want to get drunk, but also how it might actually be good for us to tie one on now and then.

The first edition of Cladistic Biogeography was published in 1986. It was a concise exposition of the history, methods, applications of, and prospects for cladistic biogeography, or the study of the historical and evolutionary relationships between species based on their distribution patterns. Well reviewed, and widely used in teaching, Cladistic Biogeography is still in demand, despite having been out of print for some time. This new edition has been updated throughout, with several chapters being rewritten and expanded to incorporate the latest research findings and theoretical and methodological advances in this dynamic field.

The genome's been mapped.
But what does it mean?

Arguably the most significant scientific discovery of the new century, the mapping of the twenty-three pairs of chromosomes that make up the human genome raises almost as many questions as it answers. Questions that will profoundly impact the way we think about disease, about longevity, and about free will. Questions that will affect the rest of your life.

"Genome" offers extraordinary insight into the ramifications of this incredible breakthrough. By picking one newly discovered gene from each pair of chromosomes and telling its story, Matt Ridley recounts the history of our species and its ancestors from the dawn of life to the brink of future medicine. From Huntington's disease to cancer, from the applications of gene therapy to the horrors of eugenics, Matt Ridley probes the scientific, philosophical, and moral issues arising as a result of the mapping of the genome. It will help you understand what this scientific milestone means for you, for your children, and for humankind.

The Earth teems with life: in its oceans, forests, skies and cities. Yet there's a black hole at the heart of biology. We do not know why complex life is the way it is, or, for that matter, how life first began. In The Vital Question, award-winning author and biochemist Nick Lane radically reframes evolutionary history, putting forward a solution to conundrums that have puzzled generations of scientists. For two and a half billion years, from the very origins of life, single-celled organisms such as bacteria evolved without changing their basic form. Then, on just one occasion in four billion years, they made the jump to complexity. All complex life, from mushrooms to man, shares puzzling features, such as sex, which are unknown in bacteria. How and why did this radical transformation happen? The answer, Lane argues, lies in energy: all life on Earth lives off a voltage with the strength of a lightning bolt. Building on the pillars of evolutionary theory, Lane's hypothesis draws on cutting-edge research into the link between energy and cell biology, in order to deliver a compelling account of evolution from the very origins of life to the emergence of multicellular organisms, while offering deep insights into our own lives and deaths. Both rigorous and enchanting, The Vital Question provides a solution to life's vital question: why are we as we are, and indeed, why are we here at all?

This exciting new textbook examines the concepts of evolution as the underlying cause of the rich diversity of life on earth-and our danger of losing that rich diversity. Written as a college textbook, The Diversity and Evolution of Plants introduces the great variety of life during past ages, manifested by the fossil record, using a new natural classification system. It begins in the Proterozoic Era, when bacteria and bluegreen algae first appeared, and continues through the explosions of new marine forms in the Helikian and Hadrynian Periods, land plants in the Devonian, and flowering plants in the Cretaceous. Following an introduction, the three subkingdoms of plants are discussed. Each chapter covers one of the eleven divisions of plants and begins with an interesting vignette of a plant typical of that division. A section on each of the classes within the division follows. Each section describes where the groups of plants are found and their distinguishing features. Discussions in each section include phylogeny and classification, general morphology, and physiology, ecological significance, economic uses, and potential for research. Suggested readings and student exercises are found at the end of each chapter.

This book links the molecular evolution of silk proteins to the evolution and behavioral ecology of web-spinning spiders and other arthropods.
