Dr. Randolph Nesse, an evolutionary biologist and physician, is one of the world’s preeminent researchers in evolutionary medicine. This young field of research applies modern evolutionary theory to questions of health in order to understand why our bodies are designed to be vulnerable to pathogens and diseases. This approach has driven important advances in our understanding of antibiotic resistance, cancer, autoimmune disease and anatomy. Randolph Nesse’s current research focuses on how natural selection shaped our psychological states, moods and anxieties.
