Although commonly believed that males are more promiscuous than females, new research has revealed that female infidelity is a common occurrence throughout the animal kingdom. Female Infidelity and Paternal Uncertainty is the first book to address how males deal with the consequences of female infidelity and the strategies they have evolved to try to avoid the possibility of raising an offspring they unknowingly did not sire. Each chapter deals with a specific evolved strategy developed to aid males in either limiting opportunities for their mate to be unfaithful or to 'correct' the by-products of infidelity should it occur. With sections including mate guarding, intra-vaginal tactics and paternity assessment, this book will appeal to researchers and graduate students in behavioral biology, evolutionary psychology, human sexuality, anthropology, sociology, reproductive health and medicine.

This volume presents the intricate ways in which sperm compete to fertilize eggs and how this has prompted reinterpretations of breeding behavior from a biological perspective. Sperm Competition in Humans: Classic and Contemporary Readings provides a theoretical framework for the study of sperm competition and also discusses the roles of females and the relationships between paternal care in sperm competition. The chapters focus on everything from evolutionary biology to taxonomic development.

Research conducted in the last fifteen years has placed in question many of the traditional conclusions scholars have formed about human female sexuality. Though conventional wisdom asserts that women's estrus has been evolutionarily lost, Randy Thornhill and Steven W. Gangestad assert that it is present, though concealed. Women, they propose, therefore exhibit two sexualities each ovulatory cycle-estrus and sexuality outside of the estrous phase, extended sexuality-that possess distinct functions. Synthesizing research in behavioral evolution and comparative biology, the authors provide a new theoretical framework for understanding the evolution of human female sexuality, one that is rooted in female sexuality and phylogeny across all vertebrate animals.

The interface of sexual behavior and evolutionary psychology is a rapidly growing domain, rich in psychological theories and data as well as controversies and applications. With nearly eighty chapters by leading researchers from around the world, and combining theoretical and empirical perspectives, The Cambridge Handbook of Evolutionary Perspectives on Sexual Psychology is the most comprehensive and up-to-date reference work in the field. Providing a broad yet in-depth overview of the various evolutionary principles that influence all types of sexual behaviors, the handbook takes an inclusive approach that draws on a number of disciplines and covers nonhuman and human psychology. It is an essential resource for both established researchers and students in psychology, biology, anthropology, medicine, and criminology, among other fields. Volume 3: Female Sexual Adaptations addresses theory and research focused on sexual adaptations in human females.

This e-only volume expands and updates the original 4-volume Encyclopedia of Women in Today′s World (2011), offering a wide range of new entries and new multimedia content. The entries reflect such developments as the Arab Spring that brought women′s issues in the Islamic world into sharp relief, the domination of female athletes among medal winners at the London 2012 Olympics, nine more women joining the ranks of democratically elected heads of state, and much more. The 475 articles in this e-only update (accompanied by photos and video clips) supplement the themes established in the original edition, providing a vibrant collection of entries dealing with contemporary women′s issues around the world.

“In this rigorous and beautifully researched volume, Milanich considers the tension between social and biological definitions of fatherhood, and shows how much we still have to learn about what constitutes a father.” —Andrew Solomon, author of Far from the Tree: Parents, Children, and the Search for Identity For most of human history, the notion that paternity was uncertain appeared to be an immutable law of nature. The unknown father provided entertaining plotlines from Shakespeare to the Victorian novelists and lay at the heart of inheritance and child support disputes. But in the 1920s new scientific advances promised to solve the mystery of paternity once and for all. The stakes were high: fatherhood has always been a public relationship as well as a private one. It confers not only patrimony and legitimacy but also a name, nationality, and identity. The new science of paternity, with methods such as blood typing, fingerprinting, and facial analysis, would bring clarity to the conundrum of fatherhood—or so it appeared. Suddenly, it would be possible to establish family relationships, expose adulterous affairs, locate errant fathers, unravel baby mix-ups, and discover one’s true race and ethnicity. Tracing the scientific quest for the father up to the present, with the advent of seemingly foolproof DNA analysis, Nara Milanich shows that the effort to establish biological truth has not ended the quest for the father. Rather, scientific certainty has revealed the fundamentally social, cultural, and political nature of paternity. As Paternity shows, in the age of modern genetics the answer to the question “Who’s your father?” remains as complicated as ever.
