Perspectives in Ethology


Book Description

The relations between behavior, evolution, and culture have been a subject of vigorous debate since the publication of Darwin's The Descent of Man (1871). The latest volume of Perspectives in Ethology brings anthropologists, ethologists, psychologists, and evolutionary theorists together to reexamine this important relation. With two exceptions (the essays by Brown and Eldredge), all of the present essays were originally presented at the Fifth Biannual Symposium on the Science of Behavior held in Guadalajara, Mexico, in February 1998. The volume opens with the problem of the origins of culture, tackled from two different viewpoints by Richerson and Boyd, and Lancaster, Kaplan, Hill, and Hurtado, respectively. Richerson and Boyd analyze the possible relations between climatic change in the Pleistocene and the evo lution of social learning, evaluating the boundary conditions under which social learning could increase fitness and contribute to culture. Lancaster, Kaplan, Hill, and Hurtado examine how a shift in the diet of the genus Homo toward difficult-to-acquire food could have determined (or coe volved with) unique features of the human life cycle. These two essays illus trate how techniques that range from computer modeling to comparative behavioral analysis, and that make use of a wide range of data, can be used for drawing inferences about past selection pressures. As culture evolves, it must somehow find its place within (and also affect) a complex hierarchy of behavioral and biological factors.




Theories of Human Evolution


Book Description

The question of human origin has always been disputed by evolution theorists. This book provides a comprehensive survey of the debates over human evolution from the time of Darwin to the 1940s. Part 1 discusses the early controversies, noting that they focused on philosophical issues rather than causes or details of the evolutionary process. A framework for the debate is outlined, considering evolution theory with race, culture and the progress of humankind. Part 2 describes various theories including the Neanderthal-Phase theory, the Presapiens theory, the Tarsioid theory, and Polytypic theories. Part 3 of the book deals with interpretations of the causes of human evolution. Arguments are presented which relate to the factors of brain expansion, upright posture and environment in the evolutionary process. Trends in human evolution are discussed, including convergence, Lamarckism, nonadaptive trends, and orthogenesis. The book ends with a review of arguments concerning Broom's (1933) question: The coming of man--was it accident or design? An extensive listing of references is provided in a bibliography and note section. (TW)

The Selfish Gene


Book Description

Science need not be dull and bogged down by jargon, as Richard Dawkins proves in this entertaining look at evolution. The themes he takes up are the concepts of altruistic and selfish behaviour; the genetical definition of selfish interest; the evolution of aggressive behaviour; kinshiptheory; sex ratio theory; reciprocal altruism; deceit; and the natural selection of sex differences. 'Should be read, can be read by almost anyone. It describes with great skill a new face of the theory of evolution.' W.D. Hamilton, Science







The Symbolic Species: The Co-evolution of Language and the Brain


Book Description

"A work of enormous breadth, likely to pleasantly surprise both general readers and experts."—New York Times Book Review This revolutionary book provides fresh answers to long-standing questions of human origins and consciousness. Drawing on his breakthrough research in comparative neuroscience, Terrence Deacon offers a wealth of insights into the significance of symbolic thinking: from the co-evolutionary exchange between language and brains over two million years of hominid evolution to the ethical repercussions that followed man's newfound access to other people's thoughts and emotions. Informing these insights is a new understanding of how Darwinian processes underlie the brain's development and function as well as its evolution. In contrast to much contemporary neuroscience that treats the brain as no more or less than a computer, Deacon provides a new clarity of vision into the mechanism of mind. It injects a renewed sense of adventure into the experience of being human.




The Psychology of the Human-Animal Bond


Book Description

There have been dramatic increases in the financial, emotional, and psychological investment in pets over the past four decades. The increasing importance of animal companions in people's lives has resulted in growing emphasis on the human-animal bond within academic literature. This book introduces practicing and emerging professionals to vital subject matter concerning this growing specialty area by providing an essential framework and information through which to consider the unique contextual backdrop of the human-animal bond. Such contexts include a wide array of themes including: issues of attachment and loss, success and frustration with making and sustaining connections, world views regarding animal ethics, familial history of neglect or abuse, and cultural dynamics that speak to the order of things between mankind and nature. Adopting a contextual stance will aid mental health professionals in appreciating why and how this connection has become a significant part of everyday life for many. As with any other important clinical dynamic, training and preparation are needed to gain competence for professional practice and research. To this end, an ensemble of international experts across the fields of psychology and mental health explore topics that will help both new and established clinicians increase and understanding of the various ways the human-animal bond manifests itself. Perspectives from beyond the scope of psychology and mental health such as anthropology, philosophy, literature, religion, and history are included to provide a sampling of the significant contexts in which the human-animal bond is established. What brings these divergent topics together in a meaningful way is their relevance and centrality to the contextual bonds that underlie the human-animal connection. This text will be a valuable resource that provides opportunities to deepen one's expertise in understanding the psychology of the human-animal bond.
