Which theory of aging suggests that aging is genetically determined?

Genetics play a powerful role in determining an individual's lifespan, with estimates suggesting they account for up to 35% of longevity. The question, 'which theory of aging suggests that aging is genetically determined?' leads to a deeper exploration of several biological frameworks, particularly the Programmed Theory of Aging and its specific sub-theories. These theories posit that the aging process is not a random occurrence but is instead a meticulously controlled, sequential process encoded within our DNA.

What are two main biological theories of aging?

According to the American Federation for Aging Research, over 300 theories have been proposed to explain why we age, but two main biological theories of aging dominate scientific thought: programmed theories and damage or error theories. The first suggests aging is a regulated biological process, while the second attributes it to cumulative cellular damage over time.

What is the death hormone theory of aging?

According to one aspect of the programmed theory of aging, our biological clocks act through hormones to control the pace of aging. The death hormone theory of aging is a historical concept suggesting that an excess of a specific pituitary hormone accelerates the aging process. While the idea of a single 'death hormone' has been largely debunked, it has paved the way for deeper research into how hormonal changes influence senescence.
