What Does Senescence Mean?
Senescence is deterioration with age and a diminishing of both biological and functional characteristics over time. There are two types of senescence: cellular and whole organism. Organismal senescence has more to do with higher death and fecundity rates in older organisms within a population. Senescence begins with germ-soma separation. This process can be delayed with decreased caloric intake of 50% in laboratory rats, with some species showing negligible senescence.
