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.

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.

An accessible and straightforward intro to cell biology In the newly revised Fourth Edition of Cell Biology: A Short Course, a distinguished team of researchers delivers a concise and accessible introduction to modern cell biology, integrating knowledge from genetics, molecular biology, biochemistry, physiology, and microscopy. The book places a strong emphasis on drawing connections between basic science and medicine. Telling the story of cells as the units of life in a colorful and student-friendly manner, Cell Biology: A Short Course takes an "essentials only" approach. It conveys critical points without overburdening the reader with extraneous or secondary information. Clear diagrams and examples from current research accompany special boxed sections that focus on the importance of cell biology in medicine and industry. A new feature, "BrainBoxes" describes some of the key people who created the current understanding of Cell Biology. The book has been thoroughly revised and updated since the last edition and includes: Thorough introduction to cells and tissues, membranes, organelles, and the structure of DNA and genetic code Explorations of DNA as a data storage medium, transcription and the control of gene expression, and recombinant DNA and genetic engineering Discussion of the manufacture of proteins, protein structure, and intracellular protein trafficking Description of ions and voltages, intracellular and extracellular signaling Introduction to the cytoskeleton and cell movement Discussion of cell division and apoptosis Perfect for undergraduate students seeking an accessible, one-stop reference on cell biology, Cell Biology: A Short Course is also an ideal reference for pre-med students.

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.

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.

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.

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 scientific understanding of arthropod phylogeny and evolution has changed significantly in recent decades. One of the most momentous alterations involved crustaceans, which are not a monophyletc group, but are part of a larger group along with insects: Pancrustacea. The old ideas surrounding crustacean evolution have served scientists well for many years; it is now time to turn toward new research by embracing the results derived from investigations conducted largely within this century. For example, new definitions have arisen from sources across several fields of study, and Frederick R. Schram and Stefan Koenemann have created a book that explores paleobiodiversity and the diversity of modern body plans. Developments within ontogenetic studies continue to generate remarkable insights into crustaceomorph evolution in regard to patterns of embryology and a revolution in the application of development genetics. Phylogeny techniques of analysis and new sources of data derived from molecular sequencing and genetic studies have forced scientists to consider new hypotheses concerning the interrelationships of all the pancrustaceans, both the crustaceomorphs and Hexapoda. Yet, some fossil groups still remain enigmatic (Thylacocephala). Despite this, research into fossils (even if incompletely understood) fills in gaps of our knowledge of paleobiodiversity, and it's useful for many things, including analyzing the origin and early evolution of Hexapoda. Evolution and Phylogeny of Pancrustacea demonstrates the use of multiple alternative hypotheses and other techniques through the well-executed presentation of diverse data sources involving Pancrustacea. Readers are left with clues to great mysteries, including the possible pathways of evolution within marine arthropods.

Knowledge of the evolutionary history of birds has much improved in recent decades. Fossils from critical time periods are being described at unprecedented rates and modern phylogenetic analyses have provided a framework for the interrelationships of the extant groups. This book gives an overview of the avian fossil record and its paleobiological significance, and it is the only up-to-date textbook that covers both Mesozoic and more modern-type Cenozoic birds in some detail. The reader is introduced to key features of basal avians and the morphological transformations that have occurred in the evolution towards modern birds. An account of the Cenozoic fossil record sheds light on the biogeographic history of the extant avian groups and discusses fossils in the context of current phylogenetic hypotheses. This review of the evolutionary history of birds not only addresses students and established researchers, but it may also be a useful source of information for anyone else with an interest in the evolution of birds and a moderate background in biology and geology.

Race and Human Diversity is an introduction to the study of human diversity in both its biological and cultural dimensions. Robert L. Anemone examines the biological basis of human difference and how humans have biologically and culturally adapted to life in different environments. The book discusses the history of the race concept, evolutionary theory, human genetics, and the connections between racial classifications and racism. It invites students to question the existence of race as biology, but to recognize race as a social construction with significant implications for the lived experience of individuals and populations. This second edition has been thoroughly revised, with new material on human genetic diversity, developmental plasticity and epigenetics. There is additional coverage of the history of eugenics; race in US history, citizenship and migration; affirmative action; and white privilege and the burden of race. Fully accessible for undergraduate students with no prior knowledge of genetics or statistics, this is a key text for any student taking an introductory class on race or human diversity.

A new human species will soon come to co-exist with us. This new species, 'Homo nouveau,' will be created using artificial intelligence and genetic engineering; both important tools which are in their infancy. Not only are the science and technology relatively new, but their implications in the mind of the general public are also only just beginning to enter our collective consciousness. This book expands on the research done for the author's previous book, What Comes After Homo Sapiens? Written by a medical professional and independent consultant to healthcare IT companies, The Fourth Great Transformation explores the questions of what this new species will look like, how we as humans will get along with them, and the potential threats and opportunities that will come along with genetically modified humans.

The history of life on earth is largely reconstructed from time-averaged accumulations of fossils. A glimpse at ecologic-time attributes and processes is relatively rare. However, the time-sensitive and predictability of echinoderm disarticulation makes them model organisms to determine post-mortem transportation and allows recognition of ecological-time data within paleocommunity accumulations. Unlike many other fossil groups, this has allowed research on many aspects of echinoderms and their paleocommunities, such as the distribution of soft tissues, assessment of the amount of fossil transportation prior to burial, determination of intraspecific variation, paleocommunity composition, estimation of relative abundance of taxa in paleocommunities, determination of attributes of niche differentiation, etc. Crinoids and echinoids have received the most amount of taphonomic research, and the patterns present in these two groups can be used to develop a more thorough understanding of all echinoderm clades.

The quantification of morphology through time is a vital tool in elucidating macroevolutionary patterns. Studies of disparity require intense effort but can provide insights beyond those gained using other methodologies. Over the last several decades, studies of disparity have proliferated, often using echinoderms as a model organism. Echinoderms have been used to study the methodology of disparity analyses and potential biases as well as documenting the morphological patterns observed in clades through time. Combining morphological studies with phylogenetic analyses or other disparate data sets allows for the testing of detailed and far-reaching evolutionary hypotheses.

Echinoderms elaborate a calcite skeleton composed of numerous plates with a distinct microstructure (stereom) that can be modelled into different shapes thanks to the use of a transient amorphous calcium carbonate (ACC) precursor phase and the incorporation of an intraorganic matrix during biomineralization. A variety of different types of stereom microarchitecture have been distinguished, each of them optimized for a specific function. For instance, a regular, galleried stereom typically houses collagenous ligaments, whereas an irregular, fine labyrinthic stereom commonly bears muscles. Epithelial tissues, in turn, are usually associated with coarse and dense stereom microfabrics. Stereom can be preserved in fossil echinoderms and a wide array of investigating methods are available. As many case studies have shown, a great deal of important paleobiological and paleoecological information can be decoded by studying the stereom microstructure of extinct echinoderms.

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.

The theory of evolution unites the past, present, and future of living things. It puts humanity's place in the universe into necessary perspective. Despite a history of controversy, the evidence for evolution continues to accumulate as a result of many separate strands of amazing scientific sleuthing. In The Story of Evolution in 25 Discoveries, Donald R. Prothero explores the most fascinating breakthroughs in piecing together the evidence for evolution. In twenty-five vignettes, he recounts the dramatic stories of the people who made crucial discoveries, placing each moment in the context of what it represented for the progress of science. He tackles topics like what it means to see evolution in action and what the many transitional fossils show us about evolution, following figures from Darwin to lesser-known researchers as they unlock the mysteries of the fossil record, the earth, and the universe. The book also features the stories of animal species strange and familiar, including humans-and our ties to some of our closest relatives and more distant cousins. Prothero's wide-ranging tales showcase awe-inspiring and bizarre aspects of nature and the powerful insights they give us into the way that life works. Brisk and entertaining while firmly grounded in fundamental science, The Story of Evolution in 25 Discoveries is a captivating read for anyone curious about the evidence for evolution and what it means for humanity.

In this provocative work, noted social and economic theorist Graeme D. Snooks exposes fatal flaws in the foundations of the Darwinian theory of evolution, which he deems an "artificial algorithm," as well as the neo-Darwinian synthesis adopted by many social scientists. Utilizing the historical method, Snooks develops a remarkable replacement theory of evolution, which he calls the "dynamic-strategy" theory. While the neo-Darwinian position places too great an emphasis on genetic change giving rise to untenable but popular concepts such as the "selfish gene" and fails to explain the fluctuating fortunes of life's most successful species (mankind), Snooks' framework starts by systematically observing the broad patterns of life and human society. The resultant realist theory of life posits life as a strategic pursuit (rather than a game of chance) in which organisms adopt dynamic strategies (only one of which is genetic change) to survive and prosper. Organisms' and species' progress is achieved through "strategic selection" a concept that displaces the "divine selection" of creationists and the "natural selection" of Darwinists. This new theory reveals the organism as empowered, rather than as the plaything of gods, genes, or blind chance; and it provides a new basis for humanism."

The Wonder of Flight. The Science of Evolution. From both, Richard Dawkins weaves a fascinating and beautifully illustrated account of how nature and humans have learned to overcome the pull of gravity and take to the skies.

Do you sometimes dream you can fly like a bird? Gliding effortlessly above the treetops, soaring and swooping, playing and dodging through the third dimension. Computer games, virtual reality headsets, and some drugs can lift our imagination and fly us through fabled, magical spaces. But it's not the real thing. No wonder some of the past's greatest minds, including Leonardo da Vinci's, have yearned for flying machines and struggled to design them.

Flights of Fancy is a book about flying – all the different ways of defying gravity that have been discovered by humans over the centuries and by other animals over the millions of years, from the mythical Icarus, to the sadly extinct but magnificent bird Argentavis magnificens, to the Wright Flyer and the 747. But it also means flights of digression into more general ideas and principles that take off from a discussion about actual flight.

Fascinating and elegantly written, this is a unique collaboration between one of the world's leading zoologists and a talented artist, and perfect for enquiring teenage minds.
