Identical Twins, Epigenetics & Aging: The Science Behind Longevity
8 hours ago
- Epigenetics shapes how genes function.
While DNA provides the blueprint, gene expression is controlled by environmental and cellular factors, making epigenetics a major driver of health and aging. - Aging is driven by cellular damage and stem cell decline.
As stem cells accumulate errors and telomeres shorten, the body’s ability to repair and regenerate decreases. - Identical twins can age differently.
Despite identical DNA, differences in environment, lifestyle, and epigenetics lead to noticeable variations in health, personality, and aging outcomes.
