In the present review, we have categorized the various theories of aging as evolutionary, molecular, cellular, and systemic.

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.

WebTheories and hypotheses The beginning. August Weismann was responsible for interpreting and formalizing the mechanisms of Darwinian evolution in a modern theoretical framework. In 1889, he theorized that ageing was part of life's program to make room for the next generation in order to sustain the turnover that is necessary for evolution.

Figure 9.9 … 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.
