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.

Download or read book Sexual Selection and the Descent of Man written by Bernard Campbell and published by Routledge. This book was released on 2017-07-12 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Download or read book Genotype-by-Environment Interactions and Sexual Selection written by John Hunt and published by John Wiley & Sons. This book was released on 2014-09-03 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sexual selection is recognized as being responsible for some of the most extravagant morphologies and behaviors in the natural world, as well as a driver of some of the most rapid evolution. While Charles Darwin’s theory is now a fundamental component of modern evolutionary biology, the impact of genotype-by-environment interactions on sexual selection has thus far received little attention. This book represents the first comprehensive analysis of the role genotype-by-environment interactions play in sexual selection and the potential implications that they have for the evolutionary process. The Editors have identified 13 topics that currently define the field and shed light on the impacts of these interactions on sexual selection. This includes key topics, such as resolving the lek paradox and how genotype-by-environmental interactions can compromise the honesty of sexual signals. The volume also outlines key questions that remain unanswered and provides a comprehensive guide to analyzing genotype-by-environment interactions. The mix of theory, empirical studies, and practical instructions from world leading experts make this book a particularly potent and definitive guide on the topic. It will be of interest to evolutionary biologists, spanning from genomicists to behaviorists. “This is a very timely book, covering a topic that should change the way we think about sexual selection. The contributors are all leaders and the topics should provide guidance to many PhD projects in the years to come. GEI is increasingly shown to be important, and it seems likely that it is critical in species where sexual selection is operating. This book is likely to help revitalize the study of sexual selection.” Professor Allen Moore, The University of Georgia “GEIs fascinate evolutionary biologists, but the unique consequences for sexually selected traits have been neglected - until now. This multi-authored book comprehensively explains key theoretical concepts, handles practical ‘how to’ issues and uses classic case studies to illustrate the value of studying GEIs. It is a must read for everyone interested in sexual selection.” Professor Michael Jennions, The Australian National University

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 Sexual Selection and Condition Dependence in the Fruit Fly, Drosophila Melanogaster written by Sean Christopher Andrew Clark and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: While natural selection acts to strengthen nonsexual fitness (i.e., survivorship and fecundity), the capacity for sexual selection to enhance this process is the source of much theoretical and empirical debate. The potential for sexual selection to reinforce natural selection in reducing the mutation load is rooted in condition dependence theory. This theory predicts that females select mates on the basis of condition, as indicated by condition-dependent sexual traits, and in doing so simultaneously sort them by genetic quality. The premise of condition-dependent mate choice is transferrable to non-female-choice components of selection; hence, sexual selection at its multiple stages is predicted to remove mutations deleterious to condition. Support for the notion that sexual selection in toto can reduce the mutation load is mounting; however, understanding which components of sexual selection are important in the removal of deleterious mutations remains an important challenge. To address this issue, I employed the Drosophila melanogaster model system. I demonstrated support for the capacity of sexual selection to remove deleterious mutations at multiple stages of selection (Chapters 2-4), before and after mating. Furthermore, I showed that the efficacy of sexual selection in eliminating deleterious mutations is dependent on the stage of selection (Chapter 4), and the source of mutation under selection (Chapters 2-4). I deviated slightly in research objective for my final thesis study (Chapter 5). There is mounting empirical support for precopulatory male mate choice across insect taxa, and emerging support for choice post-copulation (i.e., sperm and seminal fluid allocation). I manipulated perceived female mating status in D. melanogaster, and I demonstrated precopulatory male preference for females perceived as virgins, which suggests male choice for low ejaculate competition risk. At the postcopulatory level, males mated to perceived virgins outperformed those mated to perceived mated females in several key components of sperm competition defence; however, I did not detect a downstream fitness cost to this differential investment. Ultimately, my thesis has contributed valuable and novel results on the relative impacts of pre- and postcopulatory sexual selection on genetic quality in D. melanogaster, which collectively suggest that sexual selection can be effective against deleterious mutations.

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

Available in PDF, EPUB and Kindle. Book excerpt: Comparative analyses of the anatomy, reproductive physiology, and behaviour of extant primates and other mammals can offer important insights into the origins of human sexual behaviour, allowing us to reconstruct the origins of human mating systems, the evolution of sexual attractiveness, patterns of mate choice, and copulatory behaviour. Sexual Selection and the Origins of Human Mating Systems provides a modern synthesis of research on the evolution of human mating systems, bringing together work on reproductive physiology, behavioural biology, anthropology, primatology, palaeontology, evolutionary psychology, and sexological research. The approach taken is genuinely cross-disciplinary in scope, and provides a fascinating account of the effects of sexual selection upon human evolution in the light of the latest advances in the field.

Download or read book The Evolution of Sex Determination written by Leo W. Beukeboom and published by . This book was released on 2014 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis and the fusion of two gametes of different sexes or mating types. Sex-determination mechanisms are responsible for the sexual fate and development of sexual characteristics in an organism, be it a unicellular alga, a plant, or an animal. In many cases, sex determination is genetic: males and females have different alleles or different genes that specify their sexual morphology. In animals, this is often accompanied by chromosomal differences. In other cases, sex may be determined by environmental (e.g. temperature) or social variables (e.g. the size of an organism relative to other members of its population). Surprisingly, sex-determination mechanisms are not evolutionarily conserved but are bewilderingly diverse and appear to have had rapid turnover rates during evolution. Evolutionary biologists continue to seek a solution to this conundrum. What drives the surprising dynamics of such a fundamental process that always leads to the same outcome: two sex types, male and female? The answer is complex but the ongoing genomic revolution has already greatly increased our knowledge of sex-determination systems and sex chromosomes in recent years. This novel book presents and synthesizes our current understanding, and clearly shows that sex-determination evolution will remain a dynamic field of future research. The Evolution of Sex Determination is an advanced, research level text suitable for graduate students and researchers in genetics, developmental biology, and evolution.

Available in PDF, EPUB and Kindle. Book excerpt: Evolutionary psychology and behavioural genetics are two successful and important fields in the study of human behaviour, but practitioners in these subjects have different conceptions of the nature of human intelligence. Evolutionary psychologists dispute the existence of general intelligence and emphasise the differences among species. They argue that natural and sexual selection would be expected to produce intelligences that are specialised for particular domains, as encountered by particular species. Behavioural geneticists consider general intelligence to be the most fundamental aspect of intelligence and concentrate on the differences between individuals of the same species. This exciting book features papers and discussion contributions from leading behavioural geneticists, evolutionary psychologists and experts on intelligence that explore the differences and the tensions between these two approaches. The nature of 'g' or general intelligence is discussed in detail, as is the issue of the heritability of intelligence. The alternative approaches that emphasise domain-specific intelligences are explored, alongside wide-ranging discussions on a broad range of issues such as the biological basis for intelligence, animal models and changes in IQ scores over time.
