A bold, provocative history of our species finds the roots of civilization's success and failure in our evolutionary biology.We are living through the most prosperous age in all of human history, yet people are more listless, divided and miserable than ever. Wealth and comfort are unparalleled, and yet our political landscape grows ever more toxic, and rates of suicide, loneliness, and chronic illness continue to skyrocket. How do we explain the gap between these two truths? What's more, what can we do to close it? For evolutionary biologists Heather Heying and Bret Weinstein, the cause of our woes is clear: the modern world is out of sync with our ancient brains and bodies. We evolved to live in clans, but today most people don't even know their neighbors'names. Traditional gender roles once served a necessary evolutionary purpose, but today we dismiss them as regressive. The cognitive dissonance spawned by trying to live in a society we're not built for is killing us. In this book, Heying and Weinstein cut through the politically fraught discourse surrounding issues like sex, gender, diet, parenting, sleep, education, and more to outline a provocative, science-based worldview that will empower you to live a better, wiser life. They distill more than 20 years of research and first-hand accounts from the most biodiverse ecosystems on Earth into straight forward principles and guidance for confronting our culture of hyper-novelty.

Hunter-gatherer research has played a historically central role in the development of anthropological and evolutionary theory. Today, research in this traditional and enduringly vital field blurs lines of distinction between archaeology and ethnology, and seeks instead to develop perspectives and theories broadly applicable to anthropology and its many sub disciplines. In the groundbreaking first edition of Hunter-Gatherers: Archaeological and Evolutionary Theory (1991), Robert Bettinger presented an integrative perspective on hunter-gatherer research and advanced a theoretical approach compatible with both traditional anthropological and contemporary evolutionary theories.Hunter-Gatherers remains a well-respected and much-cited text, now over 20 years since initial publication. Yet, as in other vibrant fields of study, the last two decades have seen important empirical and theoretical advances. In this second edition of Hunter-Gatherers, co-authors Robert Bettinger, Raven Garvey, and Shannon Tushingham offer a revised and expanded version of the classic text, which includes a succinct and provocative critical synthesis of hunter-gatherer and evolutionary theory, from the Enlightenment to the present. New and expanded sections relate and react to recent developments—some of them the authors'own—particularly in the realms of optimal foraging and cultural transmission theories.An exceptionally informative and ambitious volume on cultural evolutionary theory, Hunter-Gatherers, second edition, is an essential addition to the libraries of anthropologists, archaeologists, and human ecologists alike.

Travis Rayne Pickering argues that the advent of ambush hunting approximately two million years ago marked a milestone in human evolution, one that established the social dynamic that allowed our ancestors to expand their range and diet. He challenges the traditional link between aggression and human predation, however, claiming that while aggressive attack is a perfectly efficient way for our chimpanzee cousins to kill prey, it was a hopeless tactic for early human hunters, who—in comparison to their large, potentially dangerous prey—were small, weak, and slow-footed. Technology that evolved from wooden spears to stone-tipped spears and ultimately to the bow and arrow increased the distance between predator and prey and facilitated an emotional detachment that allowed hunters to stalk and kill large game. Based on studies of humans and of other primates, as well as on fossil and archaeological evidence, Rough and Tumble offers a new perspective on human evolution by decoupling ideas of aggression and predation to build a more realistic understanding of what it is to be human.

Since its inception, paleoanthropology has been closely wedded to the idea that big-game hunting by our hominin ancestors arose, first and foremost, as a means for acquiring energy and vital nutrients. This assumption has rarely been questioned, and seems intuitively obvious—meat is a nutrient-rich food with the ideal array of amino acids, and big animals provide meat in large, convenient packages. Through new research, the author of this volume provides a strong argument that the primary goals of big-game hunting were actually social and political—increasing hunter's prestige and standing—and that the nutritional component was just an added bonus.Through a comprehensive, interdisciplinary research approach, the author examines the historical and current perceptions of protein as an important nutrient source, the biological impact of a high-protein diet and the evidence of this in the archaeological record, and provides a compelling reexamination of this long-held conclusion. This volume will be of interest to researchers in Archaeology, Evolutionary Biology, and Paleoanthropology, particularly those studying diet and nutrition.

Are humans by nature hierarchical or egalitarian? Hierarchy in the Forest addresses this question by examining the evolutionary origins of social and political behavior. Christopher Boehm, an anthropologist whose fieldwork has focused on the political arrangements of human and nonhuman primate groups, postulates that egalitarianism is in effect a hierarchy in which the weak combine forces to dominate the strong.The political flexibility of our species is formidable: we can be quite egalitarian, we can be quite despotic. Hierarchy in the Forest traces the roots of these contradictory traits in chimpanzee, bonobo, gorilla, and early human societies. Boehm looks at the loose group structures of hunter-gatherers, then at tribal segmentation, and finally at present-day governments to see how these conflicting tendencies are reflected.Hierarchy in the Forest claims new territory for biological anthropology and evolutionary biology by extending the domain of these sciences into a crucial aspect of human political and social behavior. This book will be a key document in the study of the evolutionary basis of genuine altruism.
