Résumé du livre

Randolph M. Nesse, MD co-founded the field of evolutionary medicine when he co-authored the book Why We Get Sick in 1994. He is also the founding director of the Center for Evolution and Medicine at the University of Arizona, a member of the American Association for the Advancement of Science, and the president of the International Society for Evolution, Medicine and Public Health.

Depression, anxiety, and other emotional challenges are deeply rooted in our evolutionary history, serving as mechanisms for survival and adaptation. While moods once guided straightforward decisions in simpler societies, modern complexities—such as career dissatisfaction or strained relationships—often blur their purpose, sometimes leading to clinical conditions. Negative emotions like jealousy, grief, and anxiety, though painful, have protective functions, shaping behaviors that enhance survival and communal well-being. However, when these emotions become overwhelming or persist unchecked, they can evolve into severe mental health disorders. Understanding these feelings through an evolutionary lens reveals their dual nature: they are both burdens and tools for growth. By addressing underlying causes and leveraging therapeutic approaches like cognitive therapy, we can navigate these challenges more effectively. As the chapter transitions, it delves further into how evolutionary forces shape human behavior, relationships, and the pursuit of well-being, offering insights into the intricate balance between biology and modern life.
