Mortal Beings: How Evolution Helps Us Understand Illness and Aging

Abstract

In these two books, biological anthropologist Richard Bribiescas and developmental psychologist David Geary address sex differences in health and aging from the perspectives of evolutionary biology and psychology. Bribiescas explores the aging process in men and describes why and how men age differently from women, with earlier mortality and greater susceptibility to the diseases of aging. Geary provides a comprehensive survey of the animal and human literature on sex differences in vulnerabilities to the effects of stress on psychological and physical traits. Both authors focus on the role of Darwinian sexual selection as the source of different health outcomes for men and women. These works make valuable contributions to our understanding of why humans get sick and age and argue convincingly for approaching medical research with a greater sensitivity to the role played by biological sex in poor health.
