Book Description
People have always been attracted to foods rich in calories, fat, and protein; yet the biblical admonition that meat be eaten "with bitter herbs" suggests that unpalatable plants play an important role in our diet. So-called primitive peoples show a surprisingly sophisticated understanding of how their bodies interact with plant chemicals, which may allow us to rediscover the origins of diet by retracing the paths of biology and culture. The domestication of the potato serves as the focus of Timothy Johns's interdisciplinary study, which forges a bold synthesis of ethnobotany and chemical ecology. The Aymara of highland Bolivia have long used varieties of potato containing potentially toxic levels of glycoalkaloids, and Johns proposes that such plants can be eaten without harm owing to human genetic modification and cultural manipulation. Drawing on additional fieldwork in Africa, he considers the evolution of the human use of plants, the ways in which humans obtain foods from among the myriad poisonous and unpalatable plants in the environment, and the consequences of this history for understanding the basis of the human diet. A natural corollary to his investigation is the origin of medicine, since the properties of plants that make them unpalatable and toxic are the same properties that make them useful pharmacologically. As our species has adapted to the use of plants, plants have become an essential part of our internal ecology. Recovering the ancient wisdom regarding our interaction with the environment preserves a fundamental part of our human heritage.

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
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
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 wide-ranging book, Nina Etkin reveals the medicinal properties of foods in the specific cultural contexts in which they are used. Incorporating co-evolution with a biocultural perspective, she addresses some of the physiological effects of foods across cultures and through history while taking into account both the complex dynamics of food choice and the blurred distinctions between food and medicine. Showing that food choice is more closely linked to health than is commonly thought, she helps us to understand the health implications of people's food-centered actions in the context of real-life circumstances."--Jacket.

Book Description
"We want to examine what the scientific evidence suggests is really going on when we eat food, and how we can eat and live in a way that best gives us the health benefits of a hunter-gatherer lifestyle while living in and enjoying the advantages of the modern world. We also hope to use the evidence to explore how we can increase our chances of avoiding chronic diseases, obesity, and other health problems -- the "Diseases of Civilization."--P. 7.

Book Description
"Quammen brilliantly and powerfully re-creates the 19th century naturalist's intellectual and spiritual journey."--Los Angeles Times Book Review Twenty-one years passed between Charles Darwin's epiphany that "natural selection" formed the basis of evolution and the scientist's publication of On the Origin of Species. Why did Darwin delay, and what happened during the course of those two decades? The human drama and scientific basis of these years constitute a fascinating, tangled tale that elucidates the character of a cautious naturalist who initiated an intellectual revolution.

Book Description
Winner, 2010 PROSE Award for Excellence in the Biological Sciences. Professional and Scholarly Publishing division of the Association of American Publishers In this unique book, Peter S. Ungar tells the story of mammalian teeth from their origin through their evolution to their current diversity. Mammal Teeth traces the evolutionary history of teeth, beginning with the very first mineralized vertebrate structures half a billion years ago. Ungar describes how the simple conical tooth of early vertebrates became the molars, incisors, and other forms we see in mammals today. Evolutionary adaptations changed pointy teeth into flatter ones, with specialized shapes designed to complement the corresponding jaw. Ungar explains tooth structure and function in the context of nutritional needs. The myriad tooth shapes produced by evolution offer different solutions to the fundamental problem of how to squeeze as many nutrients as possible out of foods. The book also highlights Ungar's own path-breaking studies that show how microwear analysis can help us understand ancient diets. The final part of the book provides an in-depth examination of mammalian teeth today, surveying all orders in the class, family by family. Ungar describes some of the more bizarre teeth, such as tusks, and the mammal diversity that accompanies these morphological wonders. Mammal Teeth captures the evolution of mammals, including humans, through the prism of dental change. Synthesizing decades of research, Ungar reveals the interconnections among mammal diet, dentition, and evolution. His book is a must-read for paleontologists, mammalogists, and anthropologists.
