Why Medicine Needs a Dose Of Evolution

The fundamental answer to why so many humans are now getting sick from previously rare illnesses is that many of the body’s features were adapted in environments from which we evolved, but have become maladapted in the modern environments we have now created. This idea, known as the mismatch hypothesis, is the core of the new emerging field of evolutionary medicine, which applies evolutionary biology to health and disease.” (Daniel E. Lieberman)
