摘要：

Adult longevity is genetically correlated with larval viability and developmental rate, and with adult fecundity and reproductive homeostatic ability in Drosophila melanogaster. More longevous strains are more viable as larvae and are more able to maintain high levels of fecundity throughout life, with less variation in fecundity due to environmental variation, than are less longevous strains. These results suggest that longevity is directly related to reproductive or Malthusian fitness and to homeostatic ability, and that natural selection must favor the evolutionary accumulation of longevity assurance factors in Drosophila melanogaster. © 1979.
