The Oxford Handbook of Evolutionary Psychology and Romantic Relationships

This handbook showcases the empirical and theoretical advancements produced by the evolutionary study of romantic relationships, tracing evolved psychological mechanisms that shape strategic computation and behavior across the lifespan of a romantic partnership. It discusses popular and cutting-edge methods for data analysis and theory development, critically analyzing the state of evolutionary relationship science and recommendations for future research.

Justin K. Mogilski earned his Ph.D. in evolutionary psychology from Oakland University in 2017. He is an Assistant Professor at the University of South Carolina, Salkehatchie. He researches how evolution has shaped brain computation to adaptively guide the decisions that people make to initiate, maintain, and dissolve intimate relationships. He has published evolutionary, social, personality, and sexual psychology journals on topics spanning mate poaching, infidelity, cross-gender friendship, intimate partner conflict, moral decision-making, morphometric cues of partner attractiveness, and multivariate statistical analyses of human mate preference.
Todd K. Shackelford received his Ph.D. in evolutionary psychology from the University of Texas at Austin in 1997. Since 2010, he is Professor and Chair of the Department of Psychology at Oakland University in Rochester, Michigan. Shackelford has published around 400 journal articles and his work has been cited around 28,000 times. Much of
Shackelford's research addresses sexual conflict between men and women, with a focus on men's physical, emotional, and sexual violence against their intimate partners.
