This video looks 12 theories current on the causes of ageing, namely: Genome damage to DNA; Telemere shortening; epigenetic malfunctions; Misfolding of ... Biological Theories of Ageing · Emerging Theories

Genetic, or programmed theories, propose that aging is genetically determined and organisms have an internal clock that programs longevity. Damage theories, ...

In the 1970s, Thomas Kirkwood added to the evolutionary biol- ogy theory of aging with his “disposable soma” theory. He believed that organisms have to balance ...

Modern biological theories of aging in humans currently fall into two main categories: programmed and damage or error theories.

Evolutionary biologists may argue that aging occurs due to the absence of natural selection at the post-reproductive stage of life (Johnson et al., 1999). Hence ...

The autoimmune theory of aging proposes that aging is due to faulty immune system functioning. In particular, the immune system attacks the body's own cells.

The genetic theory of aging states that lifespan is largely determined by the genes we inherit.

Cellular Clock Theory: This theory suggests that biological aging is due to the fact that normal cells cannot divide indefinitely. This is known as the Hayflick ...

Programmed Aging (Biological Clock): Incorporates the concepts of apoptosis, the Hayflick Limit, and the progressive shortening of telomeres with each division.
