The cycle reversed

  • Peter Calow

Abstract

C.M. Child once wrote a book with the provocative title: Senescence and Rejuvenescence (Child, 1915). It is very appropriate, however, to consider these two processes together as Child did, for any system which ages must become rejuvenated, in some sense of the word, if it is to persist. Both sexual and asexual reproduction, for example, must involve a kind of rejuvenation if their products are not to continue ageing from where the parents left off. Furthermore, in some organisms it is possible of reverse the developmental programme, and perhaps also to rejuvenate, artificially. Rejuvenation by reproduction and these contrived methods will be our main concern in this chapter.
