Description : Parents often disagree with their children over their choice of partner. Although the reasons may vary the outcome is very often one of conflict – a conflict peculiar to the human species. For the first time in one volume, Sexual Selection under Parental Choice employs an evolutionary perspective to understand this conflict and explore its implications. Covering recent developments in the field of evolutionary psychology, Menelaos Apostolou reveals the extent of parental attempts to control the mating decisions of their offspring and investigates the qualities parents seek in prospective in-laws. Children’s attempt to escape this control can lead to practices such as foot-binding and clitoridectomy or, in postindustrial societies, more subtle forms of coercion and manipulation. Apostolou demonstrates that much of human mating behavior has been shaped by parental choice and that parents have a significant influence in sexual selection: the traits they favour in their children’s mates are selected and increase in frequency in the population. Sexual Selection under Parental Choice will be ideal reading for researchers and advanced students of evolutionary, developmental and social psychology, as well as other related disciplines such as social anthropology, sociology and the biological sciences.
Description : The present book aims to examine how sexual selection works in the human species. Almost all scholarly effort focuses on sexual selection in non-human species and extrapolates the findings to the human one. However, human mating has a unique pattern not found in any other species, namely parental influence over mate choice. Across preindustrial societies, the typical pattern of long-term mating is arranged marriage, where parents choose spouses for their children. By doing so, parents effectively become a sexual selection force. Traits that enhance an individual’s chance to be selected as a son- or a daughter-in-law confer important reproductive advantages to those who are endowed with them, increasing in frequency in the population. The author has coined the term parental choice to describe the sexual selection force that arises from parental control over mating. He synthesizes extensive theoretical and empirical work in order to understand and model this force. The aim is to understand which factors give rise to parental choice and to combine these insights into constructing a more formal model. It also aims to further examine whether the predictions of the model fit the patterns of mating found across different types of human societies, and how the model can be used to understand the evolution of behavioral traits involved in mating. By synthesizing the various arguments put forward and published across the literature, the book offers a comprehensive argument and overview of an aspect of sexual selection unique to our species. Furthermore, the book revises and extends previously made arguments and models, while it provides useful insights on how the proposed revision of sexual selection theory can enable us to understand a wide range of human behavioral phenomena. It should be key reading for those interested in studying sexual selection in general and in the Homo sapiens species in particular.
Description : A major new look at the evolution of mating decisions in organisms from protozoans to humans The popular consensus on mate choice has long been that females select mates likely to pass good genes to offspring. In Mate Choice, Gil Rosenthal overturns much of this conventional wisdom. Providing the first synthesis of the topic in more than three decades, and drawing from a wide range of fields, including animal behavior, evolutionary biology, social psychology, neuroscience, and economics, Rosenthal argues that "good genes" play a relatively minor role in shaping mate choice decisions and demonstrates how mate choice is influenced by genetic factors, environmental effects, and social interactions. Looking at diverse organisms, from protozoans to humans, Rosenthal explores how factors beyond the hunt for good genes combine to produce an endless array of preferences among species and individuals. He explains how mating decisions originate from structural constraints on perception and from nonsexual functions, and how single organisms benefit or lose from their choices. Both the origin of species and their fusion through hybridization are strongly influenced by direct selection on preferences in sexual and nonsexual contexts. Rosenthal broadens the traditional scope of mate choice research to encompass not just animal behavior and behavioral ecology but also neurobiology, the social sciences, and other areas. Focusing on mate choice mechanisms, rather than the traits they target, Mate Choice offers a groundbreaking perspective on the proximate and ultimate forces determining the evolutionary fate of species and populations.
Description : Bright colors, enlarged fins, feather plumes, song, horns, antlers, and tusks are often highly sex dimorphic. Why have males in many animals evolved more conspicuous ornaments, signals, and weapons than females? How can such traits evolve although they may reduce male survival? Such questions prompted Darwin's perhaps most scientifically controversial idea--the theory of sexual selection. It still challenges researchers today as they try to understand how competition for mates can favor the variety of sex-dimorphic traits. Reviewing theoretical and empirical work in this very active field, Malte Andersson, a leading contributor himself, provides a major up-to-date synthesis of sexual selection. The author describes the theory and its recent development; examines models, methods, and empirical tests; and identifies many unsolved problems. Among the topics discussed are the selection and evolution of mating preferences; relations between sexual selection and speciation; constraints on sexual selection; and sex differences in signals, body size, and weapons. The rapidly growing study of sexual selection in plants is also reviewed. This volume will interest students, teachers, and researchers in behavioral ecology and evolutionary biology.
Description : Sexual Selection: Perspectives and Models from the Neotropics presents new sexual selection research based upon neotropical species. As neotropical regions are destroyed at an alarming rate, with an estimated 140 species of rainforest plants and animals going extinct every day, it is important to bring neotropical research to the fore now. Sexual selection occurs when the male or female of a species is attracted by certain characteristics such as form, color or behavior. When those features lead to a greater probability of successful mating, they become more prominent in the species. Although most theoretical concepts concerning sexual selection and reproductive strategies are based upon North American and European fauna, the Neotropical region encompasses much more biodiversity, with as many as 15,000 plant and animal species in a single acre of rain forest. This book illustrates concepts in sexual selection through themes ranging from female cryptic choice in insects, sexual conflict in fish, interaction between sexual selection and the immune system, nuptial gifts, visual and acoustic sexual signaling, parental investment, to alternative mating strategies, among others. These approaches distinguish Sexual Selection from current publications in sexual selection, mainly because of the latitudinal and taxonomic focus, so that readers will be introduced to systems mostly unknown outside the tropics, several of which bring into question some well-established patterns for temperate regions. Synthesizes sexual selection research on species from the Neotropics Combines different perspectives and levels of analysis using a broad taxonomic basis, introducing readers to systems mostly unknown outside the tropics and bringing into question well-established patterns for temperate regions Includes contributions exploring concepts and theory as well as discussions on a variety of Neotropical vertebrates and invertebrates, such as insects, fish, arthropods and birds
Description : In this book, the authors present current research in the study of the evolutionary perspectives, mating strategies and long-term effects on genetic variation of sexual selection. Topics discussed in this compilation include sexual dimorphism in insect longevity; evidence of natural and sexual selection shaping the size of nuptial gifts among a single bush-cricket genus; mate choice copying in both sexes of the guppy; and sexual selection under parental choice.
Description : Over the course of the last four decades, Robert Cialdini's work has helped spark an intellectual revolution in which social psychological ideas have become increasingly influential. The concepts presented in his book, Influence: The Psychology of Persuasion, have spread well beyond the geographic boundaries of North America and beyond the field of academic social psychology into the areas of business, health, and politics. In this book, leading authors, who represent many different countries and disciplines, explore new developments and the widespread impact of Cialdini's work in research areas ranging from persuasion strategy and social engineering to help-seeking and decision-making. Among the many topics covered, the authors discuss how people underestimate the influence of others, how a former computer hacker used social engineering to gain access to highly confidential computer codes, and how biology and evolution figure into the principles of influence. The authors break new ground in the study of influence.
Description : Just over one hundred and thirty years ago Charles Darwin, in The Descent of Man and Selection in Relation to Sex (1871), developed remarkably accurate conclusions about man's ancestry, based on a review of general comparative anatomy and psychology in which he regarded sexual selection as a necessary part of the evolutionary process. But the attention of biologists turned to the more general concept of natural selection, in which sexual selection plays a complex role that has been little understood. This volume significantly broadens the scope of modern evolutionary biology by looking at this important and long neglected concept of great importance. In this book, which is the first full discussion of sexual selection since 1871, leading biologists bring modern genetic theory and behavior observation to bear on the subject. The distinguished authors consider many aspects of sexual selection in many species, including man, within the context of contemporary evolutionary theory and research. The result is a remarkably original and well-rounded view of the whole concept that will be invaluable especially to students of evolution and human sexual behavior. The lucid authority of the contributors and the importance of the topic will interest all who share in man's perennial fascination with his own history. The book will be of central importance to a wide variety of professionals, including biologists, anthropologists, and geneticists. It will be an invaluable supplementary text for courses in vertebrate biology, theory of evolution, genetics, and physical anthropology. It is especially important with the emergence of alternative explanations of human development, under the rubric of creationism and doctrines of intelligent design. Bernard G. Campbell is professor of anthropology at the University of California, Los Angeles. Born in Weybridge, England, he received his Ph.D. from the University of Cambridge in 1957, and has been a lecturer in anthropology at Cambridge and Harvard Universities. Among his many contributions to the field of anthropology is Human Evolution: An Introduction to Man's Adaptations.
Description : nology in New Zealand. Angeles Tan Alora reports on the Code of Pharmaceutical Marketmg Practices developed by the Pharmaceutical and Health Care Association of the Philippines. Ruud ter Meulen and his colleagues provide detailed analysis of the Remmelink Commission's report on euthanasia in the Netherlands. Kazumasa Hoshino discusses the fmdings of the Special Committee on Gene Therapy in Japan. As such examples suggest, the activities of many governmental groups and professional advisory bodies, although varied, tend to converge upon a number of especially important issues. If one peruses the index of documents discussed in Volume Four, certain topics are more often the focus of legislation and official concern than others: withholding and withdrawing treatment, access to health care, consent to treatment and experimentation, and issues posed by HIV testing and AIDS. Such a common focus should not be exaggerated, for the discussion of topics is wide-ranging. But that commonality, when in evidence, is also not surprising. It suggests that key issues and concerns in bioethics may be widely shared among modern cultures and societies, for all the distinctiveness of a particular nation's or region's response to them. Issues of informed consent, after all, implicate more fundamental matters of respect for persons and the rights of individuals in the contexts of therapy and research. Issues of access to medical care concretize deeper questions about the nature and scope of a society's welfare obligations to its citizens.
