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.
