The author discusses ageing with special regard to evolution processes. Accelaration and retardation of certain ontogenetic phases or the whole ontogenesis have developed during phylogenesis and have been fixed genetically as a special reaction norm. The limitation of life span in highly differentiated organisms after reproduction is perfected has to be considered as one of the preconditions of evolution. Considering the phylogenesis, those hypotheses which interpret ageing as a continuous accumulation of cell damage, are no longer admissable. The different theories of the genetic control for ontogenesis are discussed on the basis of international literature.
作者讨论了衰老，特别关注进化过程。在系统发育过程中，某些个体发育阶段或整个个体发育的加速和延缓已经形成，并作为一种特殊的反应规范在基因上固定下来。繁殖后高度分化的生物体寿命的限制必须被视为进化的前提条件之一。考虑到系统发育，那些将衰老解释为细胞损伤持续积累的假设不再成立。基于国际文献讨论了个体发育的遗传控制的不同理论。
