The most powerful plants--those known to transport the human mind into other dimensions of consciousness--have traditionally been regarded as sacred. In The Encyclopedia of Psychoactive Plants Christian Rätsch details the botany, history, distribution, cultivation, and preparation and dosage of more than 400 psychoactive plants. He discusses their ritual and medicinal usage, cultural artifacts made from these plants, and works of art that either represent or have been inspired by them. The author begins with 168 of the most well-known psychoactives--such as cannabis, datura, and papaver--then presents 133 lesser known substances as well as additional plants known as “legal highs,” plants known only from mythological contexts and literature, and plant products that include substances such as ayahuasca, incense, and soma. The text is lavishly illustrated with 797 color photographs--many of which are from the author’s extensive fieldwork around the world--showing the people, ceremonies, and art related to the ritual use of the world’s sacred psychoactives.

    

    Based on exhaustive research and interviews with driving experts and traffic officials around the globe, Traffic gets under the hood of the everyday activity of driving to uncover the surprisingly complex web of physical, psychological, and technical factors that explain how traffic works, why we drive the way we do, and what our driving says about us. Vanderbilt examines the perceptual limits and cognitive underpinnings that make us worse drivers than we think we are. He demonstrates why plans to protect pedestrians from cars often lead to more accidents. He shows how roundabouts, which can feel dangerous and chaotic, actually make roads safer and reduce traffic in the bargain. He uncovers who is more likely to honk at whom, and why. He explains why traffic jams form, outlines the unintended consequences of our quest for safety, and even identifies the most common mistake drivers make in parking lots. The car has long been a central part of American life; whether we see it as a symbol of freedom or a symptom of sprawl, we define ourselves by what and how we drive. As Vanderbilt shows, driving is a provocatively revealing prism for examining how our minds work and the ways in which we interact with one another. Ultimately, Traffic is about more than driving: it s about human nature. This book will change the way we see ourselves and the world around us. And who knows? It may even make us better drivers."

    While some books explore our genetic inheritance and popular television shows celebrate ancestry, this is the first book to explore how everything from DNA to emotions to names and the stories that form our lives are all part of our human legacy. This book shows how trust is inherited in Africa, silence is passed down in Tasmania, and how the history of nations is written in our DNA. From fateful, ancient encounters to modern mass migrations and medical diagnoses, Kenneally explains how the forces that shaped the history of the world ultimately shape each human who inhabits it. The Invisible History of the Human Race is a deeply researched, carefully crafted, and provocative perspective on how our stories, psychology, and genetics affect our past and our future.

    The experienced author team have reviewed the core text, expanded the Applications of Biology chapters, and added two new chapters on practical skills. Each chapter now has a set of exam-style practice questions, as well as questions to help review the material. Also included are advice on how to revise and prepare for the examinations, multiple choice questions, revision summaries and answers to all book questions.

    Why are a quarter of a billion sperm cells needed to fertilize one egg? Are women really fertile for only a few days each month? How long should women breast-feed? In How We Do It, primatologist Robert Martin draws on forty years of research to locate the origins of everything from sex cells to baby care—and to reveal what’s really �natural” when it comes to making and raising babies. He acknowledges that although it’s not realistic to reproduce like our ancestors did, there are surprising consequences to behavior we take for granted, such as bottle feeding, cesarean sections, and in vitro fertilization. How We Do It shows that once we understand our evolutionary past, we can consider what worked, what didn’t, and what it all means for the future of our species.

    By examining fossils and DNA, Shubin shows us that our hands actually resemble fish fins, our head is organized like that of a long-extinct jawless fish, and major parts of our genome look and function like those of worms and bacteria.Shubin makes us see ourselves and our world in a completely new light. Your Inner Fish is science writing at its finest-enlightening, accessible, and told with irresistible enthusiasm.

    The author, a clinical psychologist, examines religious scriptures, rituals, and canon law, highlighting the many ways in which our evolutionary legacy has shaped the development of religion and continues to profoundly influence its expression. The book focuses on the image of God as the dominant male in Judaism, Christianity, and Islam. This traditional God concept is seen as a reflection of the “dominant ape” paradigm so evident in the hierarchical social structures of primates, with whom we have a strong genetic connection.The author describes the main features of male-dominated primate social hierarchies— specifically, the role of the alpha male as the protector of the group; his sexual dominance and use of violence and oppression to attain food, females, and territory; in-group altruism vs. out-group hostility (us vs. them); and displays of dominance and submission to establish roles within the social hierarchy. The parallels between these features of primate society and human religious rituals and concepts make it clear that religion, especially its oppressive and violent tendencies, is rooted in the deep evolutionary past.This incisive analysis goes a long way toward explaining the historic and ongoing violence committed in the name of religion.

    In an engaging and wide-ranging narrative Agustin Fuentes counters these pervasive and pernicious myths about human behavior. Tackling misconceptions about what race, aggression, and sex really mean for humans, Fuentes incorporates an accessible understanding of culture, genetics, and evolution requiring us to dispose of notions of "nature or nurture." Presenting scientific evidence from diverse fields, including anthropology, biology, and psychology, Fuentes devises a myth-busting toolkit to dismantle persistent fallacies about the validity of biological races, the innateness of aggression and violence, and the nature of monogamy and differences between the sexes. A final chapter plus an appendix provide a set of take-home points on how readers can myth-bust on their own. Accessible, compelling, and original, this book is a rich and nuanced account of how nature, culture, experience, and choice interact to influence human behavior.

    And in some parts of the world, societies with atheist majorities--some of the most cooperative and prosperous in the world--have climbed religion's ladder, and then kicked it away.Big Gods answers fundamental questions about the origins and spread of world religions and helps us understand the rise of cooperative societies without belief in gods.

    In The Violinist's Thumb, he explores the wonders of the magical building block of life: DNA.There are genes to explain crazy cat ladies, why other people have no fingerprints, and why some people survive nuclear bombs. Genes illuminate everything from JFK's bronze skin (it wasn't a tan) to Einstein's genius. They prove that Neanderthals and humans bred thousands of years more recently than any of us would feel comfortable thinking. They can even allow some people, because of the exceptional flexibility of their thumbs and fingers, to become truly singular violinists. Kean's vibrant storytelling makes science entertaining, explaining human history and whimsy while showing how DNA will influence our species' future.

    A cognitive anthropologist and psychologist, Scott Atran argues that religion is a by-product of human evolution just as the cognitive intervention, cultural selection, and historical survival of religion is an accommodation of certain existential and moral elements that have evolved in the human condition.

    r/K Theory examines how all populations tend to adopt one of two psychologies as a means of adapting their behavior to the presence or absence of environmental resources. The two strategies, termed r and K, each correlate perfectly with the psychologies underlying Liberalism and Conservatism.One strategy, named the r-strategy, imbues those who are programmed with it to be averse to all peer on peer competition, embrace promiscuity, embrace single parenting, and support early onset sexual activity in youth. Obviously, this mirrors the Liberal philosophy's aversion to individual Darwinian competitions such as capitalism and self defense with firearms, as well as group competitions such as war. Likewise, Liberalism is tolerant of promiscuity, tolerant of single parenting, and more prone to support early sex education for children and the sexualization of cultural influences. Designed to exploit a plethora of resources, one will often find this r-type strategy embodied within prey species, where predation has lowered the population's numbers, and thereby increased the resources available to it's individuals.The other strategy, termed the K-strategy, imbues those who pursue it with a fierce competitiveness, as well as tendencies towards abstinence until monogamy, two-parent parenting, and delaying sexual activity until later in life. Obviously, this mirrors Conservatism's acceptance of all sorts of competitive social schemes, from free market capitalism, to war, to individuals owning and carrying private weapons for self defense. Conservatives also tend to favor abstinence until monogamy, two parent parenting with an emphasis upon "family values," and children being shielded from any sexualized stimuli until later in life. This strategy is found most commonly in species which lack predation, and whose population's have grown to the point individuals must compete with each other for the limited environmental resources that they are rapidly running out of.Meticulously substantiated with the latest research in fields from neurobiology to human behavioral ecology, this work offers an unprecedented view into not just what governs our political battles, but why these battles have arisen within our species in the first place. From showing how these two strategies adapt in other more complex species in nature, to examining what genetic and neurostructural mechanisms may produce these divergences between individuals, to showing what this theory indicates our future may hold, this work is the most thorough analysis to date of just why we have two political ideologies, why they will never agree, and why we will tend to become even more partisan in the future.

    Morell probes the moral and ethical dilemmas of recognizing that even “lesser animals” have cognitive abilities such as memory, feelings, personality, and self-awareness--traits that many in the twentieth century felt were unique to human beings.By standing behaviorism on its head, Morell brings the world of nature brilliantly alive in a nuanced, deeply felt appreciation of the human-animal bond, and she shares her admiration for the men and women who have simultaneously chipped away at what we think makes us distinctive while offering a glimpse of where our own abilities come from.
