How has Darwinian medicine improved the study of health and disease?

Darwinian medicine, also known as evolutionary medicine, has significantly advanced the study of health and disease by providing a foundational biological framework that moves beyond viewing the body merely as a designed machine.1

By applying evolutionary biology to clinical practice and research, the field has improved our understanding in several key ways:

• Addressing Vulnerabilities: It identifies why the human body remains susceptible to disease, categorizing these vulnerabilities into factors such as environmental mismatches (e.g., obesity and hypertension), evolutionary constraints, and trade-offs between reproduction and longevity.1
• Pathogen Dynamics: It uses rigorous mathematical models to track antibiotic resistance and understand the virulence of infectious organisms, which informs more effective public health policies.1
• Reinterpreting Symptoms: It recognizes that many symptoms, such as fever, pain, and anxiety, are often protective responses shaped by natural selection rather than diseases themselves.1
• Genetic Insights: It utilizes phylogenetic methods and population genetics to trace infections and identify genetic locations subject to recent selection.1
