18 Jul 2011

Senescence violates the most basic tenet of natural selection by causing death rather than individual survival. Thus, current theories favor the concept of antagonistic pleiotropy (AP) to explain how aging emerged in metazoans. Presumably, pleiotropic genes reduce vigor and limit longevity in adults.
