Book Description
Diet is key to understanding the past, present, and future of our species. Much of human evolutionary success can be attributed to our ability to consume a wide range of foods. On the other hand, recent changes in the types of foods we eat may lie at the root of many of the health problems we face today. To deal with these problems, we must understand the evolution of the human diet. Studies of traditional peoples, non-human primates, human fossil and archaeological remains, nutritional chemistry, and evolutionary medicine, to name just a few, all contribute to our understanding of the evolution of the human diet. Still, as analyses become more specialized, researchers become more narrowly focused and isolated. This volume attempts to bring together authors schooled in a variety of academic disciplines so that we might begin to build a more cohesive view of the evolution of the human diet. The book demonstrates how past diets are reconstructed using both direct analogies with living traditional peoples and non-human primates, and studies of the bones and teeth of fossils. An understanding of our ancestral diets reveals how health relates to nutrition, and conclusions can be drawn as to how we may alter our current diets to further our health.

Book Description
We are interested in the evolution of hominin diets for several reasons. One is the fundamental concern over our present-day eating habits and the consequences of our societal choices, such as obesity prevalent in some cultures and starvation in others. Another is that humans have learned to feed themselves in extremely varied environments, and these adaptations, which are fundamentally different from those of our closest biological relatives, have to have had historical roots of varying depth. The third, and the reason why most paleoanthropologists are interested in this question, is that a species' trophic level and feeding adaptations can have a strong effect on body size, locomotion, "life history strategies", geographic range, habitat choice, and social behavior. Diet is key to understanding the ecology and evolution of our distant ancestors and their kin, the early hominins. A study of the range of foods eaten by our progenitors underscores just how unhealthy many of our diets are today. This volume brings together authorities from disparate fields to offer new insights into the diets of our ancestors. Paleontologists, archaeologists, primatologists, nutritionists and other researchers all contribute pieces to the puzzle. This volume has at its core four main sections: · Reconstructed diets based on hominin fossils--tooth size, shape, structure, wear, and chemistry, mandibular biomechanics · Archaeological evidence of subsistence--stone tools and modified bones · Models of early hominin diets based on the diets of living primates--both human and non-human, paleoecology, and energetics · Nutritional analyses and their implications for evolutionary medicine New techniques for gleaning information from fossil teeth, bones, and stone tools, new theories stemming from studies of paleoecology, and new models coming from analogy with modern humans and other primates all contribute to our understanding. When these approaches are brought together, they offer an impressive glimpse into the lives of our distant ancestors. The contributions in this volume explore the frontiers of our knowledge in each of these disciplines as they address the knowns, the unknowns, and the unknowables of the evolution of hominin diets.

Book Description
In this stunningly original book, Richard Wrangham argues that it was cooking that caused the extraordinary transformation of our ancestors from apelike beings to Homo erectus. At the heart of Catching Fire lies an explosive new idea: the habit of eating cooked rather than raw food permitted the digestive tract to shrink and the human brain to grow, helped structure human society, and created the male-female division of labour. As our ancestors adapted to using fire, humans emerged as "the cooking apes". Covering everything from food-labelling and overweight pets to raw-food faddists, Catching Fire offers a startlingly original argument about how we came to be the social, intelligent, and sexual species we are today. "This notion is surprising, fresh and, in the hands of Richard Wrangham, utterly persuasive ... Big, new ideas do not come along often in evolution these days, but this is one." -Matt Ridley, author of Genome

Book Description
A landmark book of popular science that gives us a lucid and engaging account of how the human body evolved over millions of years—with charts and line drawings throughout. “Fascinating.... A readable introduction to the whole field and great on the making of our physicality.”—Nature In this book, Daniel E. Lieberman illuminates the major transformations that contributed to key adaptations to the body: the rise of bipedalism; the shift to a non-fruit-based diet; the advent of hunting and gathering; and how cultural changes like the Agricultural and Industrial Revolutions have impacted us physically. He shows how the increasing disparity between the jumble of adaptations in our Stone Age bodies and advancements in the modern world is occasioning a paradox: greater longevity but increased chronic disease. 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 and pursue better lifestyles.

Book Description
Whether we realize it or not, we carry in our mouths the legacy of our evolution. Our teeth are like living fossils that can be studied and compared to those of our ancestors to teach us how we became human. In Evolution’s Bite, noted paleoanthropologist Peter Ungar brings together for the first time cutting-edge advances in understanding human evolution with new approaches to uncovering dietary clues from fossil teeth. The result is a remarkable investigation into the ways that teeth—their shape, chemistry, and wear—reveal how we came to be. Traveling the four corners of the globe and combining scientific breakthroughs with vivid narrative, Evolution’s Bite presents a unique dental perspective on our astonishing human development.

Book Description
Believe it or not, our DNA is almost exactly the same as that of our ancestors. While scientific advances in agriculture, medicine, and technology have protected man, to some degree, from dangers such as starvation, illness, and exposure, the fact remains that our cave-dwelling cousins were considerably healthier than we are. Our paleolithic ancestors did not suffer from heart disease, diabetes, high blood pressure, or obesity. In fact, a good deal of what we view as normal aging is a modern condition that is more akin to disease than any natural state of growing older. Our predecessors were incomparably better nourished than we are, and were incredibly physically fit. And certainly none of them ever craved a doughnut, let alone tasted one. In fact, the human preference for sweet tastes and fatty textures was developed in an environment where such treats were rare, and signaled dense, useful energy. This once-helpful adaptation is the downfall of many a dieter today. It's what makes it hard to resist fats and sweets, especially when they are all around us. We are not living as we were built to live. Our genes were forged in an environment where activity was mandatory—you were active or you starved or were eaten. This created strong selective pressure for genes encoding a smart, physically adept individual capable of very high activity levels. Humans are among the most active of species, and we carry energetically expensive brains to boot. Our energy expenditures rank high among all animals. At least they once did. The New Evolution Diet by Arthur De Vany, PhD is a roadmap back to the better health our ancestors once enjoyed. By eliminating modern foods, including carbohydrates, dairy, and all processed foods from our diets, we can undo much of the damage caused by our modern food environment. The plan is based on three simple principles: 1. Enjoy the pleasure of food and do not count or restrict calories. Eat three satisfying meals a day filled with non-starchy vegetables, fruits, and high-quality, lean proteins 2. Do not starve yourself, but do go hungry episodically, for brief periods, to promote a low fasting blood insulin level and increase metabolic fat-burning. 3. Exercise less, not more, but with more playfulness and intensity. The goal is to create a strong body with a high resting metabolism and a large physiologic capacity to move through life easily—not to burn calories.

Book Description
Researchers who study ancient human diets tend to focus on meat eating because the practice of butchery is very apparent in the archaeological record. In this volume, Julie Lesnik highlights a different food source, tracing evidence that humans and their hominin ancestors also consumed insects throughout the entire course of human evolution. Lesnik combines primatology, sociocultural anthropology, reproductive physiology, and paleoanthropology to examine the role of insects in the diets of hunter-gatherers and our nonhuman primate cousins. She posits that women would likely spend more time foraging for and eating insects than men, arguing that this pattern is important to note because women are too often ignored in reconstructions of ancient human behavior. Because of the abundance of insects and the low risk of acquiring them, insects were a reliable food source that mothers used to feed their families over the past five million years. Although they are consumed worldwide to this day, insects are not usually considered food in Western societies. Tying together ancient history with our modern lives, Lesnik points out that insects are highly nutritious and a very sustainable protein alternative. She believes that if we accept that edible insects are a part of the human legacy, we may have new conversations about what is good to eat—both in past diets and for the future of food.

Book Description
“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.
