Programmed theory of aging
WebThe study proves conclusively that aging is selected for by evolution and is programmed. A result that contradicts all major mainstream theories of aging that have been proposed since the early 1900’s. It turns out August Weisman got the right answer in 1882 but with the wrong reasoning. WebA number of theories, which fall into two main categories, have been proposed in an attempt to explain the process of aging. The first category is comprised of concepts holding that aging is programmed and those positing that aging is caused by the accumulation of damage. Conversely, the latter category of

Damage occurs during general cellular function and can target DNA, proteins, or lipids. It can be caused by extrinsic factors such as toxins, or intrinsic factors such as free radicals.
