~~==Theories==~~

−

Throughout history, many theories of aging have existed. Currently, modern empirical theories of aging are categorized into two groups: stochastic damage-based theories of aging and programmed theories of aging

−

~~These groups however, are not strict categories as programmed theories of aging may also incorporate elements of damage based theories.~~

−

Especially relevant theories known to the public include the free radical theory of aging as well as aging determined by genetics. However, recently empirical evidence of a hormesis effect by free radicals as well as conflicting data weaken the free radical theory.

−

~~Additional questions include:~~

−

~~What genetic pathways might influence aging?~~

−

~~How does the evolutionary theory of aging affect programmed theories of aging?~~
