Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Sexual Selection A Very Short Introduction written by Marlene Zuk and published by Oxford University Press. This book was released on 2018-06-28 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is responsible for the differences between the sexes in so many animals, from the brilliant plumage of birds of paradise to the antlers on deer? And why are the traits that distinguish the sexes sometimes apparently detrimental to survival? Even when they look more or less alike, why do males and females sometimes behave differently? Questions like these have intrigued scientists and the public alike for many years, and new discoveries are showing us both how wildly variable the natural world is, and how some basic principles can help explain much of that variation. Like natural selection, sexual selection is a process that results from differential representation of genes in successive generations. Under sexual selection, however, the crucial characteristics that determine whether an individual reproduces depend on sexual competition, rather than survival ability. This Very Short Introduction considers the history of our understanding of sexual selection, from Darwin's key insights to the modern day. Considering the investment animals place on reproduction, variation in mating systems, sexual conflict, and the origin of sexual dimorphism, Marlene Zuk and Leigh Simmons discuss questions such as whether females can really choose between males on aesthetic grounds, and how sexual conflict is resolved in different species. They conclude with a consideration of the thorny question of how, and even if, sexual selection theory applies to humans.

Download or read book Current Perspectives on Sexual Selection written by Thierry Hoquet and published by Springer. This book was released on 2015-01-28 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This root-and-branch re-evaluation of Darwin’s concept of sexual selection tackles the subject from historical, epistemological and theoretical perspectives. Contributions from a wealth of disciplines have been marshaled for this volume, with key figures in behavioural ecology, philosophy, and the history of science adding to its wide-ranging relevance. Updating the reader on the debate currently live in behavioural ecology itself on the centrality of sexual selection, and with coverage of developments in the field of animal aesthetics, the book details the current state of play, while other chapters trace the history of sexual selection from Darwin to today and inquire into the neurobiological bases for partner choices and the comparisons between the hedonic brain in human and non-human animals. Welcome space is given to the social aspects of sexual selection, particularly where Darwin drew distinctions between eager males and coy females and rationalized this as evolutionary strategy. Also explored are the current definition of sexual selection (as opposed to natural selection) and its importance in today’s biological research, and the impending critique of the theory from the nascent field of animal aesthetics. As a comprehensive assessment of the current health, or otherwise, of Darwin’s theory, 140 years after the publication of his Descent of Man, the book offers a uniquely rounded view that asks whether ‘sexual selection’ is in itself a progressive or reactionary notion, even as it explores its theoretical relevance in the technical biological study of the twenty-first century.

Download or read book Unnatural Selection written by Mara Hvistendahl and published by ReadHowYouWant.com. This book was released on 2011 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Lianyungang, a booming port city, has China's most extreme gender ratio for children under four: 163 boys for every 100 girls. These numbers don't seem terribly grim, but in ten years, the skewed sex ratio will pose a colossal challenge. By the time those children reach adulthood, their generation will have twenty-four million more men than women. The prognosis for China's neighbors is no less bleak: Asia now has 163 million females "missing" from its population. Gender imbalance reaches far beyond Asia, affecting Georgia, Eastern Europe, and cities in the U.S. where there are significant immigrant populations. The world, therefore, is becoming increasingly male, and this mismatch is likely to create profound social upheaval. Historically, eras in which there have been an excess of men have produced periods of violent conflict and instability. Mara Hvistendahl has written a stunning, impeccably-researched book that does not flinch from examining not only the consequences of the misbegotten policies of sex selection but Western complicity with them"--
Download or read book Darwin and the Making of Sexual Selection written by Evelleen Richards and published by University of Chicago Press. This book was released on 2017-04-27 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sexual selection, or the struggle for mates, was of considerable strategic importance to Darwin s theory of evolution as he first outlined it in the "Origin of Species," and later, in the "Descent of Man," it took on a much wider role. There, Darwin s exhaustive elaboration of sexual selection throughout the animal kingdom was directed to substantiating his view that human racial and sexual differences, not just physical differences but certain mental and moral differences, had evolved primarily through the action of sexual selection. It was the culmination of a lifetime of intellectual effort and commitment. Yet even though he argued its validity with a great array of critics, sexual selection went into abeyance with Darwin s death, not to be revived until late in the twentieth century, and even today it remains a controversial theory. In unfurling the history of sexual selection, Evelleen Richards brings to vivid life Darwin the man, not the myth, and the social and intellectual roots of his theory building."
Download or read book Sex Selection of Children written by Neil G. Bennett and published by Elsevier. This book was released on 2012-12-02 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sex Selection of Children explores the strategies used to control the sex of children, the conditions under which a couple would employ a given technique, and the technology to achieve their desired family composition. It also considers the social consequences of sex-selection techniques, the legal factors that might impinge on the use of such a technology, and the ethical considerations associated with its use. Organized into 10 chapters, this book begins with an overview of some of the more humorous past approaches to sex selection. It then discusses the effects of sex selection on fertility, sex selection by means of amniocentesis and selective abortion, and the theorized link between the timing of fertilization and the sex ratio of offspring. A chapter considers a decision-making model that describes the use of sex-selection techniques by couples who wish to have a specific number of children over their entire childbearing period, while another chapter analyzes the economics of sex preference and selection. The remaining chapters address the parental preferences about the sexes of their offspring in different societies, the legal aspects of prenatal sex selection, a moral policy for sex choice, and the ethics and public policy on sex choice. This book is a valuable resource for specialists involved in fields ranging from sociology and economics to biology, public health, law, and ethics.
Download or read book Ethics and Human Reproduction written by Christine Overall and published by Routledge. This book was released on 2012-10-11 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Ethics and Human Reproduction, Christine Overall blends feminist theory and philosophical expertise to provide a coherent analysis of a range of moral questions and social policy issues pertaining to human reproduction and the new reproductive technologies. Topics covered include: sex preselection, artificial insemination, prenatal diagnosis, abortion, in vitro fertilisation and embryo transfer, surrogate motherhood, and childbirth. Throughout the book, the author examines the values and assumptions underlying common perceptions of sexuality and fertility, the status of the foetus, the value of children, the nature of parenting, and the roles of women. In so doing, she develops a feminist approach to answering questions about reproductive rights and freedoms, the value of a genetic link between mother and their offspring, the commodification of reproduction, and the effects of reproductive technologies on women and children. This book should be essential reading for anyone interested in the new reproductive technologies, biomedical ethics, and women's health.

Download or read book Sexual Selection written by Regina H. Macedo and published by Academic Press. This book was released on 2013-09-25 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
Download or read book Male Choice Female Competition and Female Ornaments in Sexual Selection written by Ingo Schlupp and published by Oxford University Press. This book was released on 2021 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Charles Darwin first proposed Sexual Selection Theory, he suggested two mechanisms: competition among males and choice by females. Although their importance is long established and extremely well understood, their mirror images have remained largely underappreciated; males also choose, and females also compete. The combination of male mate choice (MMC) and female competition (FC) may be one of the most overlooked yet important and intriguing phenomena in modern sexual selection theory. This novel text reviews our current understanding of MMC and FC, highlighting the important connections between them. It places both concepts in the context of related fields such as female choice, mating systems, and sexual selection theory more broadly. A truly holistic approach is provided which takes all the relevant elements into consideration, especially the relative roles of MMC and FC, female ornamentation, their evolutionary consequences, and their genetic basis. Considering male mate choice and female competition in this way as effectively two sides of the same coin creates a powerful paradigm for a more complete understanding of sexual selection. Male Choice, Female Competition, and Female Ornaments in Sexual Selection will be suitable for both graduate students and researchers interested in sexual selection from an evolutionary, psychological, and anthropological perspective. It will also appeal to a broader audience of behavioural ecologists and evolutionary psychologists.

Download or read book Gender before Birth written by Rajani Bhatia and published by University of Washington Press. This book was released on 2018-02-01 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the mid-1990s, the international community pronounced prenatal sex selection via abortion an “act of violence against women” and “unethical.” At the same time, new developments in reproductive technology in the United States led to a method of sex selection before conception; its US inventor marketed the practice as “family balancing” and defended it with the rhetoric of freedom of choice. In Gender before Birth, Rajani Bhatia takes on the double standard of how similar practices in the West and non-West are divergently named and framed. Bhatia’s extensive fieldwork includes interviews with clinicians, scientists, biomedical service providers, and feminist activists, and her resulting analysis extends both feminist theory on reproduction and feminist science and technology studies. She argues that we are at the beginning of a changing transnational terrain that presents new challenges to theorized inequality in reproduction, demonstrating how the technosciences often get embroiled in colonial gender and racial politics.
