Vanderbilt Researchers Show Some Anaerobic Bacteria Have Surprisingly High Mutation Rates
Feb. 17, 2026—By Andy Flick, Evolutionary Studies scientific coordinator Ask any biologist what causes DNA mutations, and oxygen will likely make the shortlist. It is reactive, super-abundant, and has been fingered as a major culprit in genetic damage for decades. So, here is a head-scratcher: if oxygen is such a DNA troublemaker, bacteria that avoid it entirely...
