REVIEW OF BIOLOGICAL HYPOTHESES EXPLAINING AGING

Abstract

The present paper analyses and organises the most relevant theories existing in the approach to the theology of aging. All the hypotheses shown have specifically and genetically marked biological and contents, but at the same time there characters is inconsistent and irregular, maybe because what we know today is still at an experiment stage and many biological theories to explain old age, all of them centred on life duration and on the restriction of vital functions, in relation to survival as a dependent variable. In any case progress nowadays in such precise types of knowledge such as genetics or molecular biology has made several of this theories reasonable safe.
