摘要：

Under a wide variety of dynamic environmental conditions, natural selection appears to favor reproductive investment in a sexually produced offspring, carrying only half of the mother's genes, over the investment in an asexually produced offspring, genetically identical to her. It is maintained that the same environmental conditions must affect the evolutionary cost and benefit of an investment in the prolongation of one's own life versus an investment in sexual reproduction, in favor of the latter. The effects of different environmental conditions on the division of resources among sexual reproduction, asexual reproduction and prolongation of life are studied. © 1990 Indian Academy of Sciences.
