The genome's been mapped. 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 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.
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. Craig's book draws together studies from biochemistry through molecular genetics, cellular physiology, ecology, and behavior to present an integrated understanding of an interesting biological system at the molecular and organizational levels.
Soil invertebrates make up diverse communities living in soil pores and on the soil surface, digging burrows and tunnels, processing organic matter and interacting with microbes. Soil is also a habitat of growing concern as many human activities cause soil degradation. This book documents the evolutionary history of soil invertebrates and their multitude of adaptations. Soil invertebrates live in a twilight zone: some have gone down to seek stability, constancy and rest, others have gone up and faced environmental variation, heat, cold and activity. And it all happens in a few decimetres, millimetres sometimes. Check out the wonderful life below ground in this book.
Imaging and visualizing fossils in three dimensions with tomography is a powerful approach in paleontology. Here, the authors introduce select destructive and non-destructive tomographic techniques that are routinely applied to fossils and review how this work has improved our understanding of the anatomy, function, taphonomy, and phylogeny of fossil echinoderms. Building on this, this Element discusses how new imaging and computational methods have great promise for addressing long-standing paleobiological questions. Future efforts to improve the accessibility of the data underlying this work will be key for realizing the potential of this virtual world of paleontology.
In On the Origin of Species (1859), Charles Darwin put forward his theory of natural selection. Conventionally, Darwin's argument for this theory has been understood as based on an analogy with artificial selection. But there has been no consensus on how, exactly, this analogical argument is supposed to work - and some suspicion too that analogical arguments on the whole are embarrassingly weak. Drawing on new insights into the history of analogical argumentation from the ancient Greeks onward, as well as on in-depth studies of Darwin's public and private writings, this book offers an original perspective on Darwin's argument, restoring to view the intellectual traditions which Darwin took for granted in arguing as he did. From this perspective come new appreciations not only of Darwin's argument but of the metaphors based on it, the range of wider traditions the argument touched upon, and its legacies for science after the Origin.
Recent arguments concerning the nature of causation in evolutionary theory, now often known as the debate between the 'causalist' and 'statisticalist' positions, have involved answers to a variety of independent questions - definitions of key evolutionary concepts like natural selection, fitness, and genetic drift; causation in multi-level systems; or the nature of evolutionary explanations, among others. This Element offers a way to disentangle one set of these questions surrounding the causal structure of natural selection. Doing so allows us to clearly reconstruct the approach that some of these major competing interpretations of evolutionary theory have to this causal structure, highlighting particular features of philosophical interest within each. Further, those features concern problems not exclusive to the philosophy of biology. Connections between them and, in two case studies, contemporary metaphysics and philosophy of physics demonstrate the potential value of broader collaboration in the understanding of evolution.

The study of echinoid evolution, diversity, and ecology has always suffered from the fact that they are represented by taxa showing widely differing architectural designs of their multi-plated skeletons, inhabiting a large range of marine paleoenvironments, which result in highly varying taphonomic biases dictating their presence and recognition. This Element addresses the taphonomy of echinoids and includes: a general introduction to the morphological features of echinoids that play a role in their preservation; a review of processes which play an important role in the differential preservation of both regular and irregular echinoids including predation and transport; a summary of taphonomic pathways included in actualistic studies for recent sea urchins and then reconstructed for fossil taxa; and finally, a case study of the variation of echinoid taphonomy across a shelf gradient using the rich Miocene echinoid fauna of Sardinia.
How did the elephant seal survive being driven to the brink of extinction in the nineteenth century? What variables determine the lifetime reproductive success of individual seals? How have elephant seals adapted to tolerate remarkable physiological extremes of nutrition, temperature, asphyxia, and pressure? Answering these questions and many more, this book is the result of the author's 50-year study of elephant seals. The chapters cover a broad range of topics including diving, feeding, migration and reproductive behavior, yielding fundamental information on general biological principles, the operation of natural selection, the evolution of social behavior, the formation of vocal dialects, colony development, and population changes over time. The book will be a valuable resource for graduate students and researchers of marine mammal behavior and reproductive life history as well as for amateur naturalists interested in these fascinating animals.
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?
Macroevolutionary inference has historically been treated as a two-step process, involving the inference of a tree, and then inference of a macroevolutionary model using that tree. Newer models blend the two steps. These methods make more complete use of fossils than the previous generation of Bayesian phylogenetic models. They also involve many more parameters than prior models, including parameters about which empiricists may have little intuition. In this Element, we set forth a framework for fitting complex, hierarchical models. The authors ultimately fit and use a joint tree and diversification model to estimate a dated phylogeny of the Cincta (Echinodermata), a morphologically distinct group of Cambrian echinoderms that lack the fivefold radial symmetry characteristic of extant members of the phylum. Although the phylogeny of cinctans remains poorly supported in places, this Element shows how models of character change and diversification contribute to understanding patterns of phylogenetic relatedness and testing macroevolutionary hypotheses.
Modern videography provides an ever-widening window into subsea echinoderm life with vast potential for new knowledge. Supported by video evidence throughout, this Element begins with time-lapse video made in 1983 on film, using an off-the-shelf camera, flash, and underwater housings. Although quality has now been significantly improved by digital imagery, films from over thirty years ago captured crinoid feeding behavior previously unknown and demonstrated a great potential to learn about many other aspects of their biology. This sequence is followed by several examples of recent digital videography from submersibles of deep-sea crinoids and remotely operated vehicles (ROVs) (stalked and unstalked), as well as close-up video of crinoids in aquaria. These recent studies enabled a new classification of crinoid arm postures, provided detailed views of food particle capture, and revealed a wide range of behaviors in taxa never before seen in life.
An enticing illustrated look at pollination, one of the most astonishing marvels of the natural world Pollination is essential to the survival of most plants on Earth. Some plants rely on the wind to transport pollen from one flower to another. Others employ an array of ingenious strategies to attract and exploit pollinators, whether they be insects, birds, or mammals. This beautifully illustrated book provides an unprecedented look at the wonders of pollination biology, drawing on the latest science to explain the extraordinarily complex relationship between plant and pollinator, and revealing why pollination is vital for healthy ecosystems and a healthy planet. Timothy Walker offers an engaging introduction to pollination biology and explores the many different tactics of plant reproduction. He shows how wind and water can be effective yet wildly unpredictable means of pollination, and describes the intimate interactions of pollinating plants with bees and butterflies, beetles and birds, and lizards and bats. Walker explores how plants entice pollinators using scents, colors, and shapes, and how plants rely on rewards as well as trickery to attract animals. He sheds light on the important role of pollination in ecology, evolution, and agriculture, and discusses why habitat management, species recovery programs, and other conservation efforts are more critical now than ever. Featuring hundreds of color photos and illustrations, Pollination is suitable for undergraduate study and is an essential resource for naturalists, horticulturalists, and backyard gardeners.
Natural selection causes adaptation, the fit between an organism and its environment. For example, the white and grey coloration of snowy owls living and breeding around the Arctic Circle provides camouflage from both predators and prey. In this Element, we explore a variety of such outcomes of the evolutionary process, including both adaptations and alternatives to adaptations, such as nonadaptive traits inherited from ancestors. We also explore how the concept of adaptation is used in evolutionary psychology and in animal behavior, and the adequacy of methods used to confirm evolutionary accounts of human traits and behaviors.
Recent advances in statistical approaches called phylogenetic comparative methods (PCMs) have provided paleontologists with a powerful set of analytical tools for investigating evolutionary tempo and mode in fossil lineages. However, attempts to integrate PCMs with fossil data often present workers with practical challenges or unfamiliar literature. This Element presents guides to the theory behind and the application of PCMs with fossil taxa. Based on an empirical dataset of Paleozoic crinoids, example analyses are presented to illustrate common applications of PCMs to fossil data, including investigating patterns of correlated trait evolution and macroevolutionary models of morphological change. The authors emphasize the importance of accounting for sources of uncertainty and discuss how to evaluate model fit and adequacy. Finally, the authors discuss several promising methods for modeling heterogeneous evolutionary dynamics with fossil phylogenies. Integrating phylogeny-based approaches with the fossil record provides a rigorous, quantitative perspective on understanding key patterns in the history of life.

Drawing on a diversity of fast-developing disciplines including genetics, physiology, pathology as well as the history of canoeing and studies of the fluctuation of sea levels, revolutionary thinker and birth pioneer Michel Odent examines the case for viewing the genus Homo as a 'marine chimpanzee' - particularly adapted to coastal areas. By exploring the practical implications of this vision of our species, including in the period surrounding birth, the author raises questions about the very survival of humanity. At a time in history when human domination of Nature is more profound than ever before, are we on the cusp of a 'symbiotic revolution'? With his characteristic ability to look at the 'big picture' and ask questions that challenge conventional thinking, Michel Odent once again manages to persuade readers to view themselves, and their species, in a new light.
The last couple of years have witnessed an unprecedented battle within Europe between values and pragmatism, and between states' interests and individuals' rights. This book examines humanitarian considerations and immigration control from two perspectives; one broader and more philosophical, the other more practical. The impetus to show compassion for certain categories of persons with vulnerabilities can depend on religious, philosophical and political thought. Manifestation of this compassion can vary from the notion of a charitable act to aid 'the wretched' in their home country, to humanitarian assistance for the 'distant needy' in foreign lands and, finally, to immigration policies deciding who to admit or expel from the country. The domestic practice of humanitarian protection has increasingly drawn in transnational law through the expansion of the EU acquis on asylum, and the interpretation of the European Court of Human Rights. |
