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.

Our ancestral diets have been critical to our success as a species. This volume brings together experts in human and primate ecology, paleontology, and evolutionary medicine. Authors offer their unique perspectives on the evolution of the human diet and the implications of recent changes in diet for health and nutrition today.

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.
