The Evolution Wars: A Guide to the Debates
by Robert J. RichardsBeginning with the lividity of Georges Cuvier at Etienne Geoffroy Saint Hillaire for daring to suggest, in 1830, the anatomical similarity between humans and animals and ending with the current efforts of creationists to discredit Darwinism with scientific-sounding jargon, this work provides an overview of the intellectual debates that have raged between supporters and detractors of Darwin, as well as within the ranks of his adherents (classicists, neo-Darwinists, sociobiologists, etc.) The author summarizes the arguments of the various factions and offers his own assessments of the relative values of the cases.
The Evolution and Classification of the Cretaceous Ammonites and their Jurassic Progenitors
by Michael Robert CooperThis book is a unique text that illustrates and describes all the nominal genera of Cretaceous ammonites and their Jurassic progenitors on the basis of their type species.There is no judgement as to validity, and the authors leaves it to the reader to subjectively recognize or synonymize those taxa as they see fit, based on the premises and philosophies to which they ascribe. The author argues that the taxonomy offered by the Treatise, the fundamental reference work, is no longer appropriate and genera need to be redefined according to testable hypotheses. The purpose of this book, therefore, is redescribe the type species of every nominal genus and to use these to construct a new phylogenetic classification not hampered by preconceived opinion. It emphasizes the importance of "trifling characters" for classification, and that taxonomic rank is not optional but is predetermined by evolutionary position. A new higher classification is introduced for the group using the higher taxa proposed for the phylogenetic classification of the Bivalvia. Hypothesized relationships are depicted by the use of cladograms, recognizing these portray only affiliations among the sample and not necessarily close taxonomic bond.This book will be of great interest to palaeontologists, geologists, stratigraphers, biogeographers and interested students of geology, and paleology. It will also make a good addition to universities, museums, and public libraries.
The Evolution and Fossil Record of Parasitism: Coevolution and Paleoparasitological Techniques (Topics in Geobiology #50)
by Kenneth De Baets John Warren HuntleyThis two-volume edited book highlights and reviews the potential of the fossil record to calibrate the origin and evolution of parasitism, and the techniques to understand the development of parasite-host associations and their relationships with environmental and ecological changes. The book deploys a broad and comprehensive approach, aimed at understanding the origins and developments of various parasite groups, in order to provide a wider evolutionary picture of parasitism as part of biodiversity. This is in contrast to most contributions by parasitologists in the literature that focus on circular lines of evidence, such as extrapolating from current host associations or distributions, to estimate constraints on the timing of the origin and evolution of various parasite groups. This approach is narrow and fails to provide the wider evolutionary picture of parasitism on, and as part of, biodiversity.Volume two focuses on the importance of direct host associations and host responses such as pathologies in the geological record to constrain the role of antagonistic interactions in driving the diversification and extinction of parasite-host relationships and disease. To better understand the impact on host populations, emphasis is given to arthropods, colonial metazoans, echinoderms, mollusks and vertebrates as hosts. In addition, novel techniques used to constrain interactions in deep time are discussed ranging from chemical and microscopic investigations of host remains, such as blood and coprolites, to the statistical inference of lateral transfer of transposons and host-parasite coevolutionary dynamics using molecular divergence time estimation.
The Evolution and Fossil Record of Parasitism: Identification and Macroevolution of Parasites (Topics in Geobiology #49)
by Kenneth De Baets John Warren HuntleyThis two-volume edited book highlights and reviews the potential of the fossil record to calibrate the origin and evolution of parasitism, and the techniques to understand the development of parasite-host associations and their relationships with environmental and ecological changes. The book deploys a broad and comprehensive approach, aimed at understanding the origins and developments of various parasite groups, in order to provide a wider evolutionary picture of parasitism as part of biodiversity. This is in contrast to most contributions by parasitologists in the literature that focus on circular lines of evidence, such as extrapolating from current host associations or distributions, to estimate constraints on the timing of the origin and evolution of various parasite groups. This approach is narrow and fails to provide the wider evolutionary picture of parasitism on, and as part of, biodiversity. Volume one focuses on identifying parasitism in the fossil record, and sheds light on the distribution and ecological importance of parasite-host interactions over time. In order to better understand the evolutionary history of parasites and their relationship with changes in the environment, emphasis is given to viruses, bacteria, protists and multicellular eukaryotes as parasites. Particular attention is given to fungi and metazoans such as bivalves, cnidarians, crustaceans, gastropods, helminths, insects, mites and ticks as parasites. Researchers, specifically evolutionary (paleo)biologists and parasitologists, interested in the evolutionary history of parasite-host interactions as well as students studying parasitism will find this book appealing.
The Evolution from Protein Chemistry to Proteomics: Basic Science to Clinical Application
by Roger L. LundbladLargely driven by major improvements in the analytical capability of mass spectrometry, proteomics is being applied to broader areas of experimental biology, ranging from oncology research to plant biology to environmental health. However, while it has already eclipsed solution protein chemistry as a discipline, it is still essentially an extension
The Evolution of Agency: Behavioral Organization from Lizards to Humans
by Michael TomaselloA leading developmental psychologist proposes an evolutionary pathway to human psychological agency.Nature cannot build organisms biologically prepared for every contingency they might possibly encounter. Instead, Nature builds some organisms to function as feedback control systems that pursue goals, make informed behavioral decisions about how best to pursue those goals in the current situation, and then monitor behavioral execution for effectiveness. Nature builds psychological agents. In a bold new theoretical proposal, Michael Tomasello advances a typology of the main forms of psychological agency that emerged on the evolutionary pathway to human beings. Tomasello outlines four main types of psychological agency and describes them in evolutionary order of emergence. First was the goal-directed agency of ancient vertebrates, then came the intentional agency of ancient mammals, followed by the rational agency of ancient great apes, ending finally in the socially normative agency of ancient humans. Each new form of psychological organization represented increased complexity in the planning, decision-making, and executive control of behavior. Each also led to new types of experience of the environment and, in some cases, of the organism&’s own psychological functioning, leading ultimately to humans&’ experience of an objective and normative world that governs all of their thoughts and actions. Together, these proposals constitute a new theoretical framework that both broadens and deepens current approaches in evolutionary psychology.
The Evolution of Animal Communication: Reliability and Deception in Signaling Systems (Monographs in Behavior and Ecology #30)
by Stephen Nowicki William A. SearcyGull chicks beg for food from their parents. Peacocks spread their tails to attract potential mates. Meerkats alert family members of the approach of predators. But are these--and other animals--sometimes dishonest? That's what William Searcy and Stephen Nowicki ask in The Evolution of Animal Communication. They take on the fascinating yet perplexing question of the dependability of animal signaling systems. The book probes such phenomena as the begging of nesting birds, alarm calls in squirrels and primates, carotenoid coloration in fish and birds, the calls of frogs and toads, and weapon displays in crustaceans. Do these signals convey accurate information about the signaler, its future behavior, or its environment? Or do they mislead receivers in a way that benefits the signaler? For example, is the begging chick really hungry as its cries indicate or is it lobbying to get more food than its brothers and sisters? Searcy and Nowicki take on these and other questions by developing clear definitions of key issues, by reviewing the most relevant empirical data and game theory models available, and by asking how well theory matches data. They find that animal communication is largely reliable--but that this basic reliability also allows the clever deceiver to flourish. Well researched and clearly written, their book provides new insight into animal communication, behavior, and evolution.
The Evolution of Beauty: How Darwin's Forgotten Theory of Mate Choice Shapes the Animal World - and Us
by Richard O. PrumA FINALIST FOR THE PULITZER PRIZENAMED A BEST BOOK OF THE YEAR BY THE NEW YORK TIMES BOOK REVIEW, SMITHSONIAN, AND WALL STREET JOURNALA major reimagining of how evolutionary forces work, revealing how mating preferences—what Darwin termed "the taste for the beautiful"—create the extraordinary range of ornament in the animal world. In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum—reviving Darwin's own views—thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons—for the mere pleasure of it—is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.
The Evolution of Charles Darwin (Routledge Revivals)
by George A. DorseyCharles Darwin is well-known throughout the world for his revolutionary work from 1859; The Origin of Species, the foundational study of evolution which greatly challenged the near-universal belief in the Christian world, at that time, of creationism. Originally published in 1928, Dorsey attempts to provide a detailed account of the scientist’s life and personality informed by letters, published works and an autobiography written by Darwin. Darwin’s life was full of challenges both in his personal life as well as his career and The Evolution of Charles Darwin explores all aspects of his life from birth to death emphasising the great impact his work had in the scientific community and humanity as a whole.
The Evolution of Chemical Knowledge: A Formal Setting for its Analysis (Wissenschaft und Philosophie – Science and Philosophy – Sciences et Philosophie)
by Jürgen Jost Guillermo RestrepoChemistry shapes and creates the disposition of the world's resources and provides novel substances for the welfare and hazard of our civilisation at an exponential rate. Can we model the evolution of chemical knowledge? This book not only provides a positive answer to the question, it provides the formal models and available data to model chemical knowledge as a complex dynamical system based on the mutual interaction of the social, semiotic and material systems of chemistry. These systems, which have evolved over the history, include the scientists and institutions supporting chemical knowledge (social system); theories, concepts and forms of communication (semiotic system) and the substances, reactions and technologies (material system) central for the chemical practice. These three systems, which have traditionally been mostly studied in isolation, are brought together in this book in a grand historical narrative, on the basis of comprehensive data sets and supplemented by appropriate tools for their formal analysis. We thereby develop a comprehensive picture of the evolution of chemistry, needed for better understanding the past, present and future of chemistry as a discipline. The interdisciplinary character of this book and its non-technical language make it an ideal complement to more traditional material in undergraduate and graduate courses in chemistry, history of science and digital humanities.
The Evolution of Chinese Filiality: Insights from the Neurosciences
by Deborah Lynn PorterThis unique book brings a fresh interdisciplinary approach to the analysis of ancient Chinese history, creating a historical model for the emergence of cultural mainstays by applying recent dramatic findings in the fields of neuroscience and cultural evolution. The centrality in Chinese culture of a deep reverence for the lives of preceding generations, filial piety, is conventionally attributed to Confucius (551-479 B.C.), who viewed hierarchical family relations as foundational for social order. Here, Porter argues that Confucian conceptions of filiality themselves evolved from a systemized set of behaviors and thoughts, a mental structure, which descended from a specific Neolithic mindset, and that this psychological structure was contoured by particular emotional conditions experienced by China’s earliest farmers. Using case study analysis from Neolithic sky observers to the dynastic cultures of the Shang and Western Zhou, the book shows how filial piety evolved as a structure of feeling, a legacy of a cultural predisposition toward particular moods and emotions that were inherited from the ancestral past. Porter also brings new urgency to the topic of ecological grief, linking the distress central to the evolution of the filial structure to its catalyst in an environmental crisis. With a blended multidisciplinary approach combining social neuroscience, cultural evolution, cognitive archaeology, and historical analysis, this book is ideal for students and researchers in neuropsychology, religion, and Chinese culture and history.
The Evolution of Communitarian Ideas: History, Theory and Practice
by Henry TamThis book deals with three key questions about communitarian ideas: how to distinguish what constitutes communitarian thinking; what lessons to take from the historical development of communitarian arguments; and why their practical implications are relevant in devising reforms at the local, national, and global levels. Each chapter covers a distinct period, with a critical exposition of the leading thinkers of that time who contributed to communitarian philosophy and politics. Beginning with an examination of the rise of proto-communitarian ideas in classical Western and Eastern thought, the book closes with a review of communitarian responses to the emergent social and technological changes in the 21st century. Readers will learn about the core features and significance of communitarian theories and practices in relation to morality, education, the economy, freedom and security, community development, and democratic governance; and how they compare and contrast with other ethical and intellectual outlooks.
The Evolution of Complex Regional Pain Syndrome: From Schloss Rettershof to a New Clinical Language
by Michael Stanton-HicksLong before any written accounts of what has come to be described as Complex Regional Pain Syndrome (CRPS), this book entails a record that began in the department of Anesthesiology headed by Dr. John Bonica who during the Pacific arena of World War II came to manage thousands of wounded servicemen many of whom suffered from this complicated clinical entity often long after their original wounds had healed. Divided into two sections, the first provides a detailed chronology of the research and establishment of diagnostic criteria for CRPS. The second section provides an overview of how CRPS is evaluated and treated, along with the research that serves as its foundations.
The Evolution of Complexity by Means of Natural Selection
by John Tyler BonnerJohn Tyler Bonner makes a new attack on an old problem: the question of how progressive increase in the size and complexity of animals and plants has occurred. "How is it," he inquires, "that an egg turns into an elaborate adult? How is it that a bacterium, given many millions of years, could have evolved into an elephant?" The author argues that we can understand this progression in terms of natural selection, but that in order to do so we must consider the role of development--or more precisely the role of life cycles--in evolutionary change. In a lively writing style that will be familiar to readers of his work The Evolution of Culture in Animals (Princeton, 1980), Bonner addresses a general audience interested in biology, as well as specialists in all areas of evolutionary biology. What is novel in the approach used here is the comparison of complexity inside the organism (especially cell differentiation) with the complexity outside (that is, within an ecological community). Matters of size at both these levels are closely related to complexity. The book shows how an understanding of the grand course of evolution can come from combining our knowledge of genetics, development, ecology, and even behavior.
The Evolution of Complexity: Simple Simulations of Major Innovations (Emergence, Complexity and Computation #37)
by Larry BullThis book gathers together much of the author’s work – both old and new - to explore a number of the key increases in complexity seen in the natural world, seeking to explain each of them purely in terms of the features of fitness landscapes. In a very straightforward manner, the book introduces basic concepts to help readers follow the main ideas. By using variations of the NK model and including the concept of the Baldwin effect, the author presents new abstract models that are able to explain why sources of evolutionary innovation (genomes, symbiosis, sex, chromosomes, multicellularity) have been selected for and hence how complexity has increased over time in some lineages.
The Evolution of Consciousness
by Bjørn GrindeThis book gives the reader an understanding of what consciousness is about, and of how to make conscious experiences more pleasant. It expands on a new theory that describes the evolutionary trajectory leading to conscious life forms. In short, the evidence suggests that consciousness first evolved some 300 million years ago as a consequence of the introduction of feelings. Feelings offer a strategy for making behavioural decisions. Besides playing a crucial role in the evolution of the human mind, they are a key factor in regard to mental health and quality of life. Fortunately, the human brain is plastic. By exploiting available options for modulating the mind, it is therefore possible to impact on what sort of experiences the brain serves. More specifically, you can strengthen the capacity for positive feelings and reduce the sway of negative feelings. The text covers biological, neurological, psychological, and philosophical aspects of the mind.
The Evolution of Culture: Volume IV (The International Library of Essays on Evolutionary Thought)
by Stefan LinquistRecent years have seen a transformation in thinking about the nature of culture. Rather than viewing culture in opposition to biology, a growing number of researchers now regard culture as subject to evolutionary processes. Recent developments in this field have shifted some of the traditional academic fault lines. Alliances are forming between researchers trained in anthropology, evolutionary biology, psychology and philosophy. Meanwhile, several distinct schools of thought have appeared which differ in their vision of what an evolutionary approach to culture should look like. This volume contains some of the most influential publications on these subjects from the past few decades. A theoretical background chapter and critical introduction identify the core issues at stake in the new study of cultural evolution. These chapters are followed by sections on each of the four dominant approaches: the phylogenetic approach, memetics, dual inheritance theory and niche construction. Following these are two chapters on closely related topics: the psychological mechanisms of culture and the existence of culture in non-human animals. Overall, this volume provides an up to date overview of some of the most exciting trends in contemporary evolutionary thought.
The Evolution of Cyber War: International Norms for Emerging-Technology Weapons
by Brian M. MazanecFormer secretary of defense Leon Panetta once described cyber warfare as “the most serious threat in the twenty-first century,” capable of destroying our entire infrastructure and crippling the nation. <p><p> Already, major cyber attacks have affected countries around the world: Estonia in 2007, Georgia in 2008, Iran in 2010, and most recently the United States. As with other methods of war, cyber technology can be used not only against military forces and facilities but also against civilian targets. Information technology has enabled a new method of warfare that is proving extremely difficult to combat, let alone defeat. <p> And yet cyber warfare is still in its infancy, with innumerable possibilities and contingencies for how such conflicts may play out in the coming decades. Brian M. Mazanec examines the worldwide development of constraining norms for cyber war and predicts how those norms will unfold in the future. Employing case studies of other emerging-technology weapons—chemical and biological, strategic bombing, and nuclear weaponry—Mazanec expands previous understandings of norm-evolution theory, offering recommendations for U.S. policymakers and citizens alike as they grapple with the reality of cyber terrorism in our own backyard.
The Evolution of Everything: How New Ideas Emerge
by Matt Ridley“Mr. Ridley’s best and most important work to date…there is something profoundly democratic and egalitarian—even anti-elitist—in this bottom-up approach: Everyone can have a role in bringing about change.” —Wall Street JournalThe New York Times bestselling author of The Rational Optimist and Genome returns with a fascinating argument for evolution that definitively dispels a dangerous, widespread myth: that we can command and control our worldHuman society evolves. Change in technology, language, morality, and society is incremental, inexorable, gradual, and spontaneous. It follows a narrative, going from one stage to the next, and it largely happens by trial and error—a version of natural selection. Much of the human world is the result of human action but not of human design: it emerges from the interactions of millions, not from the plans of a few.Drawing on fascinating evidence from science, economics, history, politics, and philosophy, Matt Ridley demolishes conventional assumptions that the great events and trends of our day are dictated by those on high. On the contrary, our most important achievements develop from the bottom up. The Industrial Revolution, cell phones, the rise of Asia, and the Internet were never planned; they happened. Languages emerged and evolved by a form of natural selection, as did common law. Torture, racism, slavery, and pedophilia—all once widely regarded as acceptable—are now seen as immoral despite the decline of religion in recent decades.In this wide-ranging, erudite book, Ridley brilliantly makes the case for evolution, rather than design, as the force that has shaped much of our culture, our technology, our minds, and that even now is shaping our future.
The Evolution of Everything: The Patterns and Causes of Big History
by Brian VillmoareBig History seeks to retell the human story in light of scientific advances by such methods as radiocarbon dating and genetic analysis. This book provides a deep, causal view of the forces that have shaped the universe, the earth, and humanity. Starting with the Big Bang and the formation of the earth, it traces the evolutionary history of the world, focusing on humanity's origins. It also explores the many natural forces shaping humanity, especially the evolution of the brain and behaviour. Moving through time, the causes of such important transformations as agriculture, complex societies, the industrial revolution, the enlightenment, and modernity are placed in the context of underlying changes in demography, learning, and social organization. Humans are biological creatures, operating with instincts evolved millions of years ago, but in the context of a rapidly changing world, and as we try to adapt to new circumstances, we must regularly reckon with our deep past.
The Evolution of Exudativory in Primates
by Anne M. Burrows Leanne T. NashThis volume covers aspects of primate exudativory, one of the least common dietary niches among primates. While all primates are generally omnivorous animals, most species, depending on body size, acquire the majority of their energy from fruit, leaves or insects and the majority of their protein from insects or leaves. However, some specialize their caloric intake around the acquisition, processing, and break-down of exudates, the saps and gums produced by trees in response to mechanical or insect damage. Compared to leaves, insects or fruits, these compounds have a unique combination of challenges to the dentition for acquisition and processing and to the gut for digestion. This volume brings together our current knowledge on the morphological, physiological, and evolutionary aspects of being a primate exudativore and to fit these into an evolutionary context. Included in this work are comparisons to marsupial exudates-feeders and the chemical characteristics of exudates.
The Evolution of Feathers: From Their Origin to the Present (Fascinating Life Sciences)
by Christian Foth Oliver W. M. RauhutFeathers are one of the most unique characteristics of modern birds and represent the most complex and colourful type of skin derivate within vertebrates, while also fulfilling various biological roles, including flight, thermal insulation, display, and sensory function. For years it was generally assumed that the origin of flight was the main driving force for the evolution of feathers. However, various discoveries of dinosaur species with filamentous body coverings, made over the past 20 years, have fundamentally challenged this idea and produced new evolutionary scenarios for the origin of feathers. This book is devoted to the origin and evolution of feathers, and highlights the impact of palaeontology on this research field by reviewing a number of spectacular fossil discoveries that document the increasing morphological complexity along the evolutionary path to modern birds. Also featuring chapters on fossil feather colours, feather development and its genetic control, the book offers a timely and comprehensive overview of this popular research topic.
The Evolution of Human Populations in Arabia
by Jeffrey I. Rose Michael D. PetragliaThe contemporary deserts of Arabia form some of the most dramatic arid landscapes in the world; yet, during many times in the past, the region was well-watered, containing evidence for rivers and lakes. Climatic fluctuations through time must have had a profound effect on human population that lived and passed through the region. In this book, paleoenvironmental specialists, archaeologists and geneticists are brought together to provide a comprehensive account of the evolution of human populations in Arabia. A wide range of topics are explored in this book, including environmental change and its impact on human populations, the movement and dispersal of populations through the region, and the origin and spread of food producing economies. New theories and interpretations are presented which provide new insights into the evolution of human populations in a key region of the world.
The Evolution of Human Sociability
by Ron VannelliHow do desires and fears motivate human sociability? What effect do these motivators have on reproductive, social and political behaviour? And, crucially, how might we understand them separate from preconceived notions of design or higher morality? Taking these questions as a focus, this book examines human evolution with the emphasis on sexual selection and the evolution of a number of human psychological processes. Exploring evolutionary, sexual and maturational processes, along with primate, fossil and geological evidence, Vannelli argues that human nature can be conceptualised as species-typical desires and fears, derived from sexual selection during human evolution, and that these are major motivators of behaviour. Presenting additional evidence from the anthropology of band societies, along with material from group behaviour, Vannelli highlights the importance of pair-bonding, friendship, alliance behaviour, vengeance seeking and interpersonal politics in social behaviour, providing a unique interdisciplinary framework for understanding human nature and the evolution of human sociability.
The Evolution of Imagination
by Stephen T. AsmaConsider Miles Davis, horn held high, sculpting a powerful musical statement full of tonal patterns, inside jokes, and thrilling climactic phrases—all on the fly. Or think of a comedy troupe riffing on a couple of cues from the audience until the whole room is erupting with laughter. Or maybe it’s a team of software engineers brainstorming their way to the next Google, or the Einsteins of the world code-cracking the mysteries of nature. Maybe it’s simply a child playing with her toys. What do all of these activities share? With wisdom, humor, and joy, philosopher Stephen T. Asma answers that question in this book: imagination. And from there he takes us on an extraordinary tour of the human creative spirit. Guided by neuroscience, animal behavior, evolution, philosophy, and psychology, Asma burrows deep into the human psyche to look right at the enigmatic but powerful engine that is our improvisational creativity—the source, he argues, of our remarkable imaginational capacity. How is it, he asks, that a story can evoke a whole world inside of us? How are we able to rehearse a skill, a speech, or even an entire scenario simply by thinking about it? How does creativity go beyond experience and help us make something completely new? And how does our moral imagination help us sculpt a better society? As he shows, we live in a world that is only partly happening in reality. Huge swaths of our cognitive experiences are made up by “what-ifs,” “almosts,” and “maybes,” an imagined terrain that churns out one of the most overlooked but necessary resources for our flourishing: possibilities. Considering everything from how imagination works in our physical bodies to the ways we make images, from the mechanics of language and our ability to tell stories to the creative composition of self-consciousness, Asma expands our personal and day-to-day forms of imagination into a grand scale: as one of the decisive evolutionary forces that has guided human development from the Paleolithic era to today. The result is an inspiring look at the rich relationships among improvisation, imagination, and culture, and a privileged glimpse into the unique nature of our evolved minds.
