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.
Sexual conflict - what happens when the reproductive interests of males and females diverge - occurs in all sexually reproducing species, including humans. This is the first volume to assemble the latest theoretical and empirical work on sexual conflict in humans from the leading scholars in the fields of evolutionary psychology and anthropology.
Kinship ties-the close relationships found within the family-have been a central focus of evolutionary biological analyses of social behavior ever since biologist William Hamilton extended the concept of Darwinian fitness to include an individual's actions benefiting not only his own offspring, but also collateral kin. Evolutionary biologists consider organisms not only reproductive strategists, but also nepotistic strategists. If a person's genes are just as likely to be reproduced in her sister as in her daughter, then we should expect the evolution of sororal investment in the same way as one expects maternal investment. This concept has revolutionized biologists' understanding of social ...
An essential primer presenting major topics of study undertaken by evolutionary cognitive neuroscientists.
In species with internal fertilization, sperm competition occurs when the sperm of two or more males simultaneously occupy the reproductive tract of a female and compete to fertilize an egg (Parker, 1970). A large body of empirical research has demonstrated that, as predicted by sperm competition theory, males and females in many species possess anatomical, behavioral, and physiological adaptations that have evolved to deal with the adaptive challenges associated with sperm competition. Moreover, in recent years, evolutionary biologists and psychologists have begun to examine the extent to which sperm competition may have been an important selective pressure during human evolution. Some rese...
Taking a multi-agency approach to domestic violence, this book looks at a range of issues that impact on those working in the healthcare field - from the starting point of identifying abuse when it's occurring, through to seeing a (hopefully) positive outcome for the individuals involved.

The Oxford Handbook of Evolutionary Family Psychology focuses on the psychology behind people's familial behavior, an understanding of which can illuminate our understanding of modern, ancient, and animal families.
The indispensable reference tool for the groundbreaking science of evolutionary psychology Why is the mind designed the way it is? How does input from the environment interact with the mind to produce behavior? These are the big, unanswered questions that the field of evolutionary psychology seeks to explore. The Handbook of Evolutionary Psychology is the seminal work in this vibrant, quickly-developing new discipline. In this thorough revision and expansion, luminaries in the field provide an in-depth exploration of the foundations of evolutionary psychology and explain the new empirical discoveries and theoretical developments that continue at a breathtaking pace. Evolutionary psychologist...
When one partner in a relationship is unfaithful to the other, it takes a lot of work by both parties involved to salvage the relationship. In today’s therapy-friendly climate, marriage/couples counseling is often a part of that rebuilding process. Many couples seek out professional therapy after an affair is out in the open, but often the act of infidelity is revealed while uncovering and discussing unrelated issues for which the couple is in counseling. And yet, amazingly, as common as this complex and difficult topic arises in therapy, there is relatively little professional literature devoted to understanding and "treating" infidelity. In this volume, Paul Peluso has assembled a truly impressive list of contributors from a range of disciplines and backgrounds, including marital therapy, family therapy, evolutionary psychology, marriage research, and cyberstudies, with the aim of filling this void.
