WebJan 26, 2024 · The programmed theory of aging asserts that aging and death are necessary parts of evolution, not of biology. If a species did not have the genetic capacity for aging and death, then it would not be forced to replicate to survive. 3. Individuals in the species would just keep on living until a climate or other change wiped them all out. WebMar 30, 2024 · Cellular clock theory of aging focuses on the lifespan of cells. Since many human cells do not continue to reproduce indefinitely, this theory suggests that aging is a result of cells hitting their programmed reproductive limit. Parts of cells just wear out. An example of this is the shortening of telomeres, the caps on cell chromosomes.
