Abstract

We review herein the concept of aging in Metazoans, showing the large diversity of cases that prevents the establishment of a general rule for the Animal Kingdom. We describe cases of species that never become old, other that show neglecting senescence and other that develop degenerative processes and decreased or absent fecundity with age. We also review the hypotheses that try to explain the evolutionary conservation of senescence processes that decrease the fitness of the animal as well as the physiological mechanisms involved in them.
