✦ Synopsis
Calorie restriction results in an increased lifespan and reduced,fecundity of rodents. In a natural environment the acailability of food will vary greatly. It is suggested that Darwinian fitness will iw increased i f animals cease breeding during periods of ,food deprivation and incest saved resources in maintenance of the adult body, or soma. This would increase the probahility of producing viable ofspring during an extended lifespan. The ditwrsion of limited energy resources from breeding to maintenance of the soma is seen as an evolutionary adaptation, fully compatible with the ' disposable soma' theory of the evolution of ageing.
