What does the genetic clock theory propose about aging?

The genetic clock theory proposes that aging is regulated by genetic factors, suggesting that our genes play a significant role in determining the lifespan and the biological aging process of an organism. This theory reflects the idea that there are specific genetic structures or sequences that control the timing of aging, including the processes of cellular and organismal development.

The genetic clock implies that our biological clock is influenced by hereditary factors, such as telomere length and the activity of certain genes associated with growth and development. As we age, the activity of these genes can lead to gradual degradation of cellular functions, ultimately resulting in the various signs and symptoms of aging. This contrasts with other explanations of aging that emphasize the roles of environmental factors, lifestyle choices, or random mutations, which do not account for the systematic and intrinsic nature of aging proposed by the genetic clock theory.
