A genetic basis for homosexuality has been all but proved, yet Darwinism, the most widely accepted evolutionary theory, emphasises successful reproduction. How do we explain a lifetime preference for non-reproductive sex? Whilst social constructionism offers explanations in terms of social learning and cultural preferences, the body of evidence for a genetic predisposition to homosexuality grows. Social learning argues that homosexual sex is merely misdirected and therefore futile, but far from dying out it continues through the ages and is found in different cultures. What if there was an evolutionary advantage to homosexuality? Straight Science? Homosexuality, Evolution and Adaptation dares to ask such questions.

Expand your knowledge—with theories and concepts that may challenge your assumptions about sexual attraction Human sexuality can be better understood by knowing how sexual psychologies may have evolved throughout the ages. Handbook of the Evolution of Human Sexuality presents a detailed examination of human sexuality, the assumptions about concepts and terms pertaining to sexuality, and the latest theories on the evolution of human sexual attraction. Leading experts explore various aspects of evolutionary theory, with a focus on Evolutionary Psychology (EP). Discussions include mate preferences, mating behavior, mate signaling, pheromones, and same-sex attraction. This comprehensive source also presents three groundbreaking theories of the evolution of same-sex attraction. Handbook of the Evolution of Human Sexuality takes current assumptions about human sexuality, explains each in turn, and then offers fresh perspectives on conventional concepts of sexual orientation. This extensive resource provides ample evidence to argue that researchers should investigate sexual relationships based on a person’s characteristics such as personal traits, complementary roles/status, sexual acts, or situational context rather than simply the sex of the partner. The book provides a discussion of evolutionary theory, evolution of human sexual culture, evolution of sexual pleasure, and detailed analysis of assumptions about sexual orientation. The text is carefully referenced. Some of the topics explored by Handbook of the Evolution of Human Sexuality include: links to non-human primate sexual behaviors and the emergence of human (sexual) nature EP research on consensual adult human sexual behaviors studies of evolved male and female mating strategies, mate preferences, and sexual psychologies a brief history of the theory of evolution ancient culture, archeology, and an overview of premodern human sexuality evolutionary history of sexual pleasure human mating strategies development of mate preferences sexual signals, such as distinctive physical features, material wealth, etc. theories of the evolution of same-sex sexual attraction and behavior Primatologist Paul Vasey’s observations of female Japanese macaques and their female-female sexual encounters—with an examination of human male-male behavior evolutionary history of female-female affectional bonding with a new theory on the behavior evolutionary history of male-male sexual behavior—with intriguing thoughts on why it happened evolutionary history of pheromones as chemical messengers much more Handbook of the Evolution of Human Sexuality is an important, thought-provoking resource perfect for evolutionary psychologists, sexologists, educators, researchers, scholars, and graduate students.

The book aims to revitalise the interdisciplinary debate about evolutionary ethics and substantiate the idea that evolution science can provide a rational and robust framework for understanding morality. It also traces pathways for knowledge-based choices to be made about directions for future long-term biological evolution and cultural development in view of adaptation to the expected, probable and possible future and the ecological sustainability of our planetary environment The authors discuss ethical challenges associated with the major biosocial sources of human variation: individual variation, inter-personal variation, inter-group variation, and inter-generational variation. This book approaches the long-term challenges of the human species in a holistic way. Researchers will find an extensive discussion of the key theoretical scientific aspects of the relationship between evolution and morality. Policy makers will find information that can help them better understand from where we are coming and inspire them to make choices and take actions in a longer-term perspective. The general public will find food for thoughts.

Our experience of the world is driven by processes common to all animals: growth, survival, reproduction and death. Evolution and Human Behaviour explores the complexities of the human experience through the lens of Darwinism, drawing on a long and vibrant tradition of different theories and interpretations. This textbook offers a compelling synthesis of key concepts, addressing human thought, feeling and behaviour in fundamental evolutionary terms. This is a essential text for undergraduate students taking courses in psychology, human biology, ethology, anthropology and human behavioural ecology, providing an insightful and comprehensive introduction for anyone who wishes to understand how human behaviour has evolved. new_to_this_edition Additional chapters on health and disease, homosexuality, the nature of adaptations and life history theory Includes brand-new material on epigenetics, patterns of crime, error management theory, moral foundations theory, religion and gene culture co-evolution Now accompanied by a companion website offering additional reading material and useful practice questions New 'controversy' boxes in each chapter, providing ideas for essay topics and classroom discussion

This book provides a comprehensive analysis of the evolutionary origins of same-sex attraction, evaluating multiple existing evolutionary theories. It combines empirical findings with theoretical arguments in order to review evidence on the prevalence rates of same-sex attraction and determine its genetic and environmental basis. Among the topics addressed: Attitudes towards same-sex attraction across human history Assessing the weak selection pressures hypothesis of attraction Assessing the male choice hypothesis of attraction Evolution of same-sex attraction in men versus women The Evolution of Same-Sex Attraction will be of interest to academics and students of evolutionary and psychological sciences, filling a gap in literature on the origins of specifically same-sex attraction.

A broad overview of the science of evolution, and why understanding it matters in our everyday lives. Explaining Life through Evolution tells the origin story of life on this planet and how we arrived at the tremendous diversity among organisms that we see around us today. Prosanta Chakrabarty explains evolution in a concise, accessible, and engaging way, emphasizing the importance of understanding evolution in everyday contemporary life. Weaving his own lived experience among discussions of Darwin and the origins of evolutionary thought, Chakrabarty also covers key concepts to our understanding of our current condition, including mutation; the spectrum of race, sex, gender, and sexuality; the limitations of ancestry tests; and the evolution of viruses like SARS-CoV-2, the virus at the heart of the COVID-19 pandemic. Offering a contemporary update to classic popular evolution books by Stephen Jay Gould, Jerry Coyne, and others, Explaining Life through Evolution is not only an illuminating read, but also an essential guide to the kind of scientific literacy that we need in order to face the challenges of our collective future.

This book examines human psychology and behavior through the lens of modern evolutionary psychology. Evolutionary Psychology: The Ne w Science of the Mind, 5/e provides students with the conceptual tools of evolutionary psychology, and applies them to empirical research on the human mind. Content topics are logically arrayed, starting with challenges of survival, mating, parenting, and kinship; and then progressing to challenges of group living, including cooperation, aggression, sexual conflict, and status, prestige, and social hierarchies. Students gain a deep understanding of applying evolutionary psychology to their own lives and all the people they interact with.

In Sex, Gender and Science , Myra Hird outlines the social study of science and nature, specifically in relation to 'sex', sex 'differences' and sexuality. She examines how Western understandings of 'sex' are based less upon understanding material sex differences, than on a discourse that emphasizes sex dichotomy over sex diversity and argues for a feminist engagement with scientific debate that embraces the diversity and complexity of nature.

I have long been awe-struck by authors' claims that their books had been in the making for 5, or 10, or even 15 years. I now have a better appreciation ofthe work involved in bringing a book to press. The seeds of this project have had a long germination. The impetus for this book began more than 10 years ago when I was a graduate student in clinical psychology. Having an interest in human sexuality-and in theories on the forms of sexual attraction specifically-I was perplexed by various perspectives on this subject. Disciplines of thought that I encountered medicine, evolutionary biology, developmental psychology, gay/lesbian theory, social constructionism, anthropology, Marxism, Christianity, and others-perceived the issue so differently, so strongly, with almost no overlap. I was fascinated that the question ofhow and why one is attracted to either one or both sexes could elicit such conviction and divergent points of view. There seemed to be no easy way to resolve these differences. Still, what frustrated me most in my readings were several conceptual problems among the two prominent proponents of contemporary sexuality theory scientists and social constructionists. One ofmy first frustrations with biomedical and social scientists who write about sexuality was that they often define sexual attraction in strict behavioral terms, as completed observable sexual acts--observable in the sense that such acts or their consequences are seen by others.

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.
