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...

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...

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...

The field of forensic psychology explores the intersection of psychology and the law. The purpose of this book is to examine topics in the field using the powerful, multidisciplinary, conceptually integrated approach that the natural sciences have embraced for decades with great success.

Darwin's theory of evolution by natural selection is the meta-theoretical framework that unifies the field of biology. It unites research and understanding of the development, control, and organization of behavior. The study of humans, which includes all of the social sciences, is part of the field of...

This book is an introduction to the emerging field of evolutionary cognitive neuroscience, a branch of neuroscience that combines the disciplines of evolutionary psychology and cognitive neuroscience. It outlines the application of cognitive neuroscientific methods (e.g., functional magnetic resonance imaging, transcranial magnetic stimulation, magneto- and electroencephalography, and the use of neuropsychiatric and neurosurgical patients) to answer empirical questions posed from an evolutionary meta-theoretical perspective. Chapters outline the basics of cognitive evolution and how the...

This Encyclopedia provides a comprehensive overview of individual differences within the domain of personality, with major sub-topics including assessment and research design, taxonomy, biological factors, evolutionary evidence, motivation, cognition and emotion, as well as gender differences, cultural considerations, and personality disorders.

The Oxford Handbook of Evolutionary Perspectives on Violence, Homicide, and War synthesizes the theoretical and empirical work of leading scholars in the evolutionary sciences to produce the first extensive and authoritative review of this literature. The handbook includes chapters on intimate partner violence, child abuse, sibling violence, suicide, adolescent bullying, sexual abuse, religious terrorism, animal cruelty, and several chapters addressing human and non-human intergroup aggression and war. This breadth of coverage is unique, and ensures that the handbook provides...

Sexual conflict -- what happens when the reproductive interests of males and females diverge -- occurs in all sexually reproducing species, including humans. The Oxford Handbook of Sexual Conflict in Humans 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.

Following an introductory section that outlines theory and research on sexual conflict in humans and non-humans, ensuing sections discuss human sexual conflict and its manifestations before...
