A Hunter Gatherers Guide To The 21st Century

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.

A provocative exploration of the tension between our evolutionary history and our modern woes—and what we can do about it. We are living through the most prosperous age in all of human history, yet we are listless, divided, and miserable. Wealth and comfort are unparalleled, but our political landscape is unmoored, and rates of suicide, lone­liness, and chronic illness continue to skyrocket. How do we explain the gap between these truths? And how should we respond? For evolutionary biologists Heather Heying and Bret Weinstein, the cause of our troubles is clear: the accelerat­ing rate of change in the modern world has outstripped the capacity of our brains and bodies to adapt. We evolved to live in clans, but today many people don’t even know their neighbors’ names. In our haste to discard outdated gender roles, we increasingly deny the flesh-and-blood realities of sex—and its ancient roots. The cognitive dissonance spawned by trying to live in a society we are not built for is killing us. In this book, Heying and Weinstein draw on decades of their work teaching in college classrooms and explor­ing Earth’s most biodiverse ecosystems to confront today’s pressing social ills—from widespread sleep deprivation and dangerous diets to damaging parenting styles and back­ward education practices. Asking the questions many mod­ern people are afraid to ask, A Hunter-Gatherer’s Guide to the 21st Century outlines a science-based worldview that will empower you to live a better, wiser life.

We evolved to live in clans, but today many people don't even know their neighbours' names. Survival in our earliest societies depended on living in harmony with nature, but today the food we eat, the work we do - even the light we absorb - is radically different from what our minds and bodies evolved to expect.

The New York Times bestselling coauthor of Sex at Dawn explores the ways in which “progress” has perverted the way we live—how we eat, learn, feel, mate, parent, communicate, work, and die—in this “engaging, extensively documented, well-organized, and thought-provoking” (Booklist) book. Most of us have instinctive evidence the world is ending—balmy December days, face-to-face conversation replaced with heads-to-screens zomboidism, a world at constant war, a political system in disarray. We hear some myths and lies so frequently that they feel like truths: Civilization is humankind’s greatest accomplishment. Progress is undeniable. Count your blessings. You’re lucky to be alive here and now. Well, maybe we are and maybe we aren’t. Civilized to Death counters the idea that progress is inherently good, arguing that the “progress” defining our age is analogous to an advancing disease. Prehistoric life, of course, was not without serious dangers and disadvantages. Many babies died in infancy. A broken bone, infected wound, snakebite, or difficult pregnancy could be life-threatening. But ultimately, Christopher Ryan questions, were these pre-civilized dangers more murderous than modern scourges, such as car accidents, cancers, cardiovascular disease, and a technologically prolonged dying process? Civilized to Death “will make you see our so-called progress in a whole new light” (Book Riot) and adds to the timely conversation that “the way we have been living is no longer sustainable, at least as long as we want to the earth to outlive us” (Psychology Today). Ryan makes the claim that we should start looking backwards to find our way into a better future.

Epigenetics can potentially revolutionize our understanding of the structure and behavior of biological life on Earth. It explains why mapping an organism's genetic code is not enough to determine how it develops or acts and shows how nurture combines with nature to engineer biological diversity. Surveying the twenty-year history of the field while also highlighting its latest findings and innovations, this volume provides a readily understandable introduction to the foundations of epigenetics. Nessa Carey, a leading epigenetics researcher, connects the field's arguments to such diverse phenomena as how ants and queen bees control their colonies; why tortoiseshell cats are always female; why some plants need cold weather before they can flower; and how our bodies age and develop disease. Reaching beyond biology, epigenetics now informs work on drug addiction, the long-term effects of famine, and the physical and psychological consequences of childhood trauma. Carey concludes with a discussion of the future directions for this research and its ability to improve human health and well-being.

“With . . . evidence from recent genetic and anthropological research, [Zuk] offers a dose of paleoreality.”—Erin Wayman, Science News We evolved to eat berries rather than bagels, to live in mud huts rather than condos, to sprint barefoot rather than play football—or did we? Are our bodies and brains truly at odds with modern life? Although it may seem as though we have barely had time to shed our hunter-gatherer legacy, biologist Marlene Zuk reveals that the story is not so simple. Popular theories about how our ancestors lived—and why we should emulate them—are often based on speculation, not scientific evidence. Armed with a razor-sharp wit and brilliant, eye-opening research, Zuk takes us to the cutting edge of biology to show that evolution can work much faster than was previously realized, meaning that we are not biologically the same as our caveman ancestors. Contrary to what the glossy magazines would have us believe, we do not enjoy potato chips because they crunch just like the insects our forebears snacked on. And women don’t go into shoe-shopping frenzies because their prehistoric foremothers gathered resources for their clans. As Zuk compellingly argues, such beliefs incorrectly assume that we’re stuck—finished evolving—and have been for tens of thousands of years. She draws on fascinating evidence that examines everything from adults’ ability to drink milk to the texture of our ear wax to show that we’ve actually never stopped evolving. Our nostalgic visions of an ideal evolutionary past in which we ate, lived, and reproduced as we were “meant to” fail to recognize that we were never perfectly suited to our environment. Evolution is about change, and every organism is full of trade-offs. From debunking the caveman diet to unraveling gender stereotypes, Zuk delivers an engrossing analysis of widespread paleofantasies and the scientific evidence that undermines them, all the while broadening our understanding of our origins and what they can really tell us about our present and our future.

In this landmark book of popular science, Daniel E. Lieberman—chair of the department of human evolutionary biology at Harvard University and a leader in the field—gives us a lucid and engaging account of how the human body evolved over millions of years, even as it shows how the increasing disparity between the jumble of adaptations in our Stone Age bodies and advancements in the modern world is occasioning this paradox: greater longevity but increased chronic disease. The Story of the Human Body brilliantly illuminates as never before the major transformations that contributed key adaptations to the body: the rise of bipedalism; the shift to a non-fruit-based diet; the advent of hunting and gathering, leading to our superlative endurance athleticism; the development of a very large brain; and the incipience of cultural proficiencies. Lieberman also elucidates how cultural evolution differs from biological evolution, and how our bodies were further transformed during the Agricultural and Industrial Revolutions. While these ongoing changes have brought about many benefits, they have also created conditions to which our bodies are not entirely adapted, Lieberman argues, resulting in the growing incidence of obesity and new but avoidable diseases, such as type 2 diabetes. Lieberman proposes that many of these chronic illnesses persist and in some cases are intensifying because of “dysevolution,” a pernicious dynamic whereby only the symptoms rather than the causes of these maladies are treated. And finally—provocatively—he advocates the use of evolutionary information to help nudge, push, and sometimes even compel us to create a more salubrious environment.

The epic story and ultimate big history of how human society evolved from intimate chimp communities into the sprawling civilizations of a world-dominating species If a chimpanzee ventures into the territory of a different group, it will almost certainly be killed. But a New Yorker can fly to Los Angeles--or Borneo--with very little fear. Psychologists have done little to explain this: for years, they have held that our biology puts a hard upper limit--about 150 people--on the size of our social groups. But human societies are in fact vastly larger. How do we manage--by and large--to get along with each other? In this paradigm-shattering book, biologist Mark W. Moffett draws on findings in psychology, sociology and anthropology to explain the social adaptations that bind societies. He explores how the tension between identity and anonymity defines how societies develop, function, and fail. Surpassing Guns, Germs, and Steel and Sapiens, The Human Swarm reveals how mankind created sprawling civilizations of unrivaled complexity--and what it will take to sustain them.
