A number of scholars have found that concepts such as mutation, selection, and random drift, which emerged from the theory of biological evolution, may also explain evolutionary phenomena in other disciplines as well. Drawing on these concepts, Professors Cavalli-Sforza and Feldman classify and systematize the various modes of transmitting "culture" and explore their consequences for cultural evolution. In the process, they develop a mathematical theory of the non-genetic transmission of cultural traits that provides a framework for future investigations in quantitative social and anthropological science. The authors use quantitative models that incorporate the various modes of transmission (for example, parent-child, peer-peer, and teacher-student), and evaluate data from sociology, archaeology, and epidemiology in terms of the models. They show that the various modes of transmission in conjunction with cultural and natural selection produce various rates of cultural evolution and various degrees of diversity within and between groups. The same framework can be used for explaining phenomena as apparently unrelated as linguistics, epidemics, social values and customs, and diffusion of innovations. The authors conclude that cultural transmission is an essential factor in the study of cultural change.

Culture shapes vast swathes of our lives and has allowed the human species to dominate the planet in an evolutionarily unique way. This book is unique in focusing on the evolutionary continuities in culture, providing an interdisciplinary exploration of culture, written by leading authorities from the biological and cognitive sciences.

The book considers the challenge of poverty and deterioration of the ecological environment in China, particularly in rural areas. Examining key factors such as the overuse of natural resources and the loss of biodiversity in the face of an expanding population and rapidly developing economy. It focuses on examining the frameworks of rural households in poor mountainous areas in rural China, considering their livelihood choices and decision-making processes. It analyses the relationship between these households’ livelihoods and their environment, notably farmers’ attitudes and perceptions towards ecological conservation policies, and their use of forest resources. Cutting across the fields of population studies, sociology, economy and environment, this is an important read for scholars and students interested in how China is dealing with the challenges of natural resources exploitation, sustainable development and social welfare.

The transformation of vibrations into electric energy through the use of piezoelectric devices is an exciting and rapidly developing area of research with a widening range of applications constantly materialising. With Piezoelectric Energy Harvesting, world-leading researchers provide a timely and comprehensive coverage of the electromechanical modelling and applications of piezoelectric energy harvesters. They present principal modelling approaches, synthesizing fundamental material related to mechanical, aerospace, civil, electrical and materials engineering disciplines for vibration-based energy harvesting using piezoelectric transduction. Piezoelectric Energy Harvesting provides the first comprehensive treatment of distributed-parameter electromechanical modelling for piezoelectric energy harvesting with extensive case studies including experimental validations, and is the first book to address modelling of various forms of excitation in piezoelectric energy harvesting, ranging from airflow excitation to moving loads, thus ensuring its relevance to engineers in fields as disparate as aerospace engineering and civil engineering. Coverage includes: Analytical and approximate analytical distributed-parameter electromechanical models with illustrative theoretical case studies as well as extensive experimental validations Several problems of piezoelectric energy harvesting ranging from simple harmonic excitation to random vibrations Details of introducing and modelling piezoelectric coupling for various problems Modelling and exploiting nonlinear dynamics for performance enhancement, supported with experimental verifications Applications ranging from moving load excitation of slender bridges to airflow excitation of aeroelastic sections A review of standard nonlinear energy harvesting circuits with modelling aspects.

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. Table of Contents: The Question of Egalitarian Society Hierarchy and Equality Putting Down Aggressors Equality and Its Causes A Wider View of Egalitarianism The Hominoid Political Spectrum Ancestral Politics The Evolution of Egalitarian Society Paleolithic Politics and Natural Selection Ambivalence and Compromise in Human Nature References Index Reviews of this book: This well-written book, geared toward an audience with background in the behavioral and evolutionary sciences but accessible to a broad readership, raises two general questions: 'What is an egalitarian society?' and 'How have these societies evolved?'...[Christopher Boehm] takes the reader on a journey from the Arctic to the Americas, from Australia to Africa, in search of hunter-gatherer and tribal societies that emanate the egalitarian ethos--one that promotes generosity, altruism and sharing but forbids upstartism, aggression and egoism. Throughout this journey, Boehm tantalizes the reader with vivid anthropological accounts of ridicule, criticism, ostracism and even execution--prevalent tactics used by subordinates in egalitarian societies to level the social playing field...Hierarchy in the Forest is an interesting and thought-provoking book that is surely an important contribution to perspectives on human sociality and politics. --Ryan Earley, American Scientist Reviews of this book: Combing an exhaustive ethnographic survey of human societies from groups of hunter-gatherers to contemporary residents of the Balkans with a detailed analysis of the behavioral attributes of non-human primates (chimpanzees, gorillas, bonobos), Boehm focuses on whether humans are hierarchical or egalitarian by nature...[Boehm's hypotheses] are invariably intriguing and well documented...He raises topics of wide interest and his book should get attention. --Publishers Weekly Boehm has been the first to look at egalitarianism with a cold, unromantic eye. He sees it as a victory over hierarchical tendencies, which are equally marked in our species. I would predict that his insightful examination will reverberate within anthropology and the social sciences as well as among biologists interested in the evolution of social systems. --Frans de Waal, Emory University Hierarchy in the Forest is an original and stimulating contribution to thinking about the origins of egalitarianism. I personally find Boehm's ideas convincing, but whether one agrees with him or not, he has formulated his hypotheses in such a way that this book is likely to set the terms of the discussion for the forseeable future. --Barbara Smuts, University of Michigan The most unique and interesting feature of this clear, well written book is the way Boehm links the study of nonhuman primates (particularly chimpanzees) to traditional concepts of political anthropology. As a political scientist, I was intrigued by Boehm's suggestion that democracy, both ancient and modern, could be understood as the expression of the same natural dispositions that support the egalitarianism of nomadic bands and sedentary tribes. I expect that many scholars in biology, anthropology, and the social sciences would learn from this stimulating book. Even those who disagree with Boehm's arguments are likely to be provoked in instructive ways. --Larry Arnhart, Northern Illinois University Chris Boehm boldly and cogently attacks a whole orthodoxy in anthropology which sees hunter-gatherer 'egalitarianism' as somehow the basic form of human society. No praise can be too high for Boehm's brilliant and courageous book. --Robin Fox, Rutgers University

An acclaimed biologist draws on a wide range of his own and others' research into the behavior of fish, birds, whales, and humans to reveal the failure of genetic determination to explain mating behavior and the fundamental process of learning.
