Book Description
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.

Book Description
Jim McKnight examines both the biological and the social evolutionary theories of the causation of homosexuality. He considers such questions as, how the discovery of a gay gene would fit with Darwin's theory of 'survival of the fittest'.

Book Description
What causes a child to grow up gay or straight? In this book, neuroscientist Simon LeVay summarizes a wealth of scientific evidence that points to one inescapable conclusion: Sexual orientation results primarily from an interaction between genes, sex hormones, and the cells of the developing body and brain. In this revised edition LeVay broadens his horizons. He adds a new chapter on bisexuality, reviews some uncommon forms of sexuality such as asexuality and pedophilia, and considers whether there could be a biological basis for subtypes of gay people such as "butch" and "femme" lesbians.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
Where did we come from? What is our connection with other life forms? What are the mechanisms of mind that define what it means to be a human being? In the seventh edition of this revolutionary textbook, David M. Buss examines human behavior from an evolutionary perspective, providing students with the conceptual tools needed to study evolutionary psychology and apply them to empirical research on the human mind. Content is organised by topic, beginning with the challenges of survival, mating, parenting, and kinship; progressing to challenges of group living, including cooperation, aggression, sexual conflict and status, prestige, and social hierarchies. Key features of this edition include: • Updated and enhanced material based on an explosion of new theories and research, including dozens of new references. • Expanded coverage of topics including socioecology, behavior, emotions, and gender. • Exploration of evolutionary mismatches in several domains such as survival, kinship, and mating, including a discussion of internet dating. With a wealth of student-friendly pedagogy including critical thinking questions and case study boxes supporting the application of evolutionary psychology to real-world situations, this is an invaluable resource for undergraduates studying psychology, biology, and anthropology. The textbook is also supported by a range of instructor resources, including PowerPoint slides, a test bank, and an instructor’s manual, to help students achieve their higher learning goals.
