Ancient DNA tests the notion that allergies are due to our dirtier past
Our take
Recent analyses of ancient DNA challenge the prevailing notion that increased allergies stem from our increasingly sanitized lifestyles. Instead, emerging research indicates that certain immune genes, inherited from our ancestors, may actually contribute to a lower risk of developing allergies. By examining the genetic makeup of ancient populations in relation to modern disease risks, scientists are uncovering a complex interplay between our evolutionary history and contemporary health challenges.
An analysis of ancient DNA and modern disease risk suggests some immune genes may reduce allergy risk rather than increase it.
