This book was released on 2012-12-06 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic studies aimed at understanding the origin of species are dominating major scientific journals. In the past decade, genetic tools that were previously available only in model systems have become accessible to investigators working on nearly all species. Concurrent with these technical advances has been an increase in understanding of both the importance of considering the ecological context of speciation and testing hypotheses about causes for species formation. Many recent studies suggest a prominent role of sexual selection in species formation. These advances have produced a need for a synthesis of what we now understand about speciation, and perhaps more importantly, where we should go from here. In this volume, several leading investigators and rising stars have contributed reviews and/or novel primary research findings aimed at understanding the ultimate mystery on which Darwin named his most famous and influential book. Fundamental to the origin of species is the evolution of mate choice systems. This collection of papers discusses burgeoning genetic, evolutionary, and ecological approaches to understanding the origins of mating discrimination and causes of premating reproductive isolation both within and between species. The individual contributions span a wide spectrum of disciplines, taxa, and ideas (some controversial). This synthesis brings together several of the most recent ideas with supporting empirical data. This book will be of particular interest to both undergraduate and postgraduate researchers and students and researchers in the field of evolutionary biology, genetics and animal behaviour.

This book was released on 2007-12-04 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essay from the year 2002 in the subject Biology - Behaviour, grade: 2.1, Oxford Brookes University, language: English, abstract: The “good gene” hypothesis is one of the main hypotheses regarding sexual selection by female mate choice. Sexual selection was first defined by Darwin as “the advantage which certain individuals have over others of the same sex and species, in exclusive relation to reproduction”. He devised sexual selection theory to account for the evolution of survival-decreasing traits, which nevertheless increase individual reproductive success by enabling individuals to acquire mates in competition with others. Sexual selection consists of two components, one arising when the members of one sex compete for mates (often called intrasexual selection) and the other occurring when members of the choosier sex determine which members of the other sex will have a chance to mate (often called intersexual selection). The good gene hypothesis is concerned with the latter or rather with the evolution of female preferences for male traits. First, I am going to outline the main components of the good gene hypothesis and then I am going to explore whether there is any evidence that females choose on the basis of “good genes”.

Download or read book The Mating Mind written by Geoffrey Miller and published by Anchor. This book was released on 2011-12-21 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: At once a pioneering study of evolution and an accessible and lively reading experience, a book that offers the most convincing—and radical—explanation for how and why the human mind evolved. Consciousness, morality, creativity, language, and art: these are the traits that make us human. Scientists have traditionally explained these qualities as merely a side effect of surplus brain size, but Miller argues that they were sexual attractors, not side effects. He bases his argument on Darwin’ s theory of sexual selection, which until now has played second fiddle to Darwin’ s theory of natural selection, and draws on ideas and research from a wide range of fields, including psychology, economics, history, and pop culture. Witty, powerfully argued, and continually thought-provoking, The Mating Mind is a landmark in our understanding of our own species.
Download or read book Genotype by environment Interactions and Sexual Selection written by Fiona Caroline Ingleby and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Genotype-by-environment interactions (G x Es) describe genetic variation for phenotypic plasticity, such that the relative performance of genotypes varies across environments. These interactions have been studied in the context of natural selection for decades, but research interest in the evolutionary consequences of G x Es in sexual traits is more recent. Theory suggests that G x Es in sexual traits could be of fundamental importance to the operation of sexual selection across heterogeneous environments, but empirical research lags behind the theory. In this thesis, I review the current literature on the role of G x Es in sexual selection and identify areas for further research. Using cuticular hydrocarbons (CHCs) in the fruit fly Drosophila simulans as a model system for sexual selection, I examine G x Es in trait expression and quantify the effect of these G x Es in terms of sexual signal reliability and the coevolution of male and female sexual traits. To do so, I use a combination of quantitative genetics and laboratory environmental manipulations. First, I demonstrate that male CHC profile is subject to sexual selection through female mate choice and find some variation in patterns of mate choice across diets and temperatures (Chapter 3). Next, I identify G x Es in male and female CHC expression across diets and temperatures, although G x Es in male CHC profile across temperatures are weak (Chapter 4). I find that G x Es in male CHC expression can cause sexual signal unreliability, as predicted by theory, since male CHCs do not reliably signal heritable aspects of male attractiveness across diets and temperatures (Chapter 5). I also find G x Es in some aspects of female mate choice across temperatures (Chapter 6). In spite of the evidence for signal unreliability and variation in female mate choice across environments, I show that the overall outcome of mate choice is unaffected by G x Es, such that the same male genotypes are attractive across diets and temperatures (Chapters 5 and 6). From my results, it seems likely that females assess male attractiveness based on multiple male sexual signals, so that whilst male CHCs influence mate choice, CHC profile does not necessarily correlate well with overall male attractiveness. I discuss the implications of these results for the evolution of sexual traits and the genetic covariance between male and female sexual traits across environments. The research in this thesis highlights the importance of multivariate studies of sexual selection across environments for a more complete understanding of the evolution of sexual traits.
Download or read book Sexual Selection written by Malte Andersson and published by Princeton University Press. This book was released on 2019-12-31 with total page pages. 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 Female Control written by William Eberhard and published by Princeton University Press. This book was released on 2019-12-31 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: A growing body of evidence has begun to reveal flaws in the traditional assumption of female passivity and lack of discrimination after copulation has begun. William Eberhard has compiled an impressive array of research on the ability of females to shape the outcome of mating. He describes studies of many different cryptic mechanisms by which a female can accept a male for copulation but nevertheless reject him as a father. Evidence from various fields indicates that such selectivity by females may be the norm rather than the exception. Because most post-copulatory competition between males for paternity is played out within the bodies of females, female behavior, morphology, and physiology probably often influence male success in these contests. Eberhard draws examples from a diversity of organisms, ranging from ctenophores to scorpions, nematodes to frogs, and crickets to humans. Cryptic female choice establishes a new bridge between sexual selection theory and reproductive physiology, in particular the physiological effects of male seminal products on female reproductive processes, such as sperm transport, oviposition, and remating. Eberhard interweaves his review of previous studies with speculation on the consequences of this theoretical development, and indicates promising new directions for future research.
Download or read book Looking for a Few Good Males written by Erika L. Milam and published by JHU Press. This book was released on 2010-03-15 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: 2010 Outstanding Academic Title, Choice Magazine Why do female animals select certain mates, and how do scientists determine the answer? In considering these questions, Erika Lorraine Milam explores the fascinating patterns of experiment and interpretation that emerged as twentieth-century researchers studied sexual selection and female choice. Approaching the topic from both biological and animal-studies perspectives, Milam not only presents a broad history of sexual selection—from Darwin to sociobiology—but also analyzes the animal-human continuum from the perspectives of sex, evolution, and behavior. She asks how social and cultural assumptions influence human-animal research and wonders about the implications of gender on scientific outcomes. Although female choice appears to be a straightforward theoretical concept, the study of sexual selection has been anything but simple. Scientists in the early twentieth century investigated female choice in animals but did so with human social and sexual behavior as their ultimate objective. By the 1940s, evolutionary biologists and population geneticists shifted their focus, studying instead how evolution affected natural animal populations. Two decades later, organismal biologists once again redefined the investigation of sexual selection as sociobiology came to dominate the discipline. Outlining the ever-changing history of this field of study, Milam uncovers lost mid-century research programs and finds that the discipline did not languish in the decades between Darwin’s theory of sexual selection and sociobiology, as observers commonly believed. Rather, population geneticists, ethologists, and organismal biologists alike continued to investigate this important theory throughout the twentieth century.
Download or read book Male Choice Female Competition and Female Ornaments in Sexual Selection written by Ingo Schlupp and published by . This book was released on 2021 with total page 164 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 Mate Choice written by Gil G. Rosenthal and published by Princeton University Press. This book was released on 2017-07-18 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Sexual Conflict written by Göran Arnqvist and published by Princeton University Press. This book was released on 2013-11-28 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past decade has seen a profound change in the scientific understanding of reproduction. The traditional view of reproduction as a joint venture undertaken by two individuals, aimed at replicating their common genome, is being challenged by a growing body of evidence showing that the evolutionary interests of interacting males and females diverge. This book demonstrates that, despite a shared genome, conflicts between interacting males and females are ubiquitous, and that selection in the two sexes is continuously pulling this genome in opposite directions. These conflicts drive the evolution of a great variety of those traits that distinguish the sexes and also contribute to the diversification of lineages. Göran Arnqvist and Locke Rowe present an array of evidence for sexual conflict throughout nature, and they set these conflicts into the well-established theoretical framework of sexual selection. The recognition of conflict between the sexes is transforming our theories for the evolution of mating systems and the sexes themselves. Written by two top researchers in the field, Sexual Conflict is the first book to describe this transformation. It is a must read for all scholars and students interested in the evolutionary biology of reproduction.

Download or read book The Evolution of Beauty written by Richard O. Prum and published by Anchor. This book was released on 2017-05-09 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: A FINALIST FOR THE PULITZER PRIZE NAMED A BEST BOOK OF THE YEAR BY THE NEW YORK TIMES BOOK REVIEW, SMITHSONIAN, AND WALL STREET JOURNAL A major reimagining of how evolutionary forces work, revealing how mating preferences—what Darwin termed "the taste for the beautiful"—create the extraordinary range of ornament in the animal world. In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum—reviving Darwin's own views—thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons—for the mere pleasure of it—is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.
