WebFigure 9.9: Theories of human aging. Genetics: One’s genetic make-up certainly plays a role in longevity, but scientists are still attempting to identify which genes are responsible. Based on animal models, some genes promote longer life, while other genes limit longevity. WebNov 1, 2015 · A related theory is the DNA damage hypothesis, which posits that incompletely repaired free radical-derived damage alters gene expression and impairs cell function. Evidence supporting this theory includes studies connecting DNA repair ability to lifespan and premature aging to genetic mutations that damage DNA repair ability.
