Abstract: A general corollary of population genetic theories of senescence is that the culture of outbred laboratory populations using females of later ages should lead to the evolution of postponed senescence. This has been tested before, but the predicted results have not been consistently reproducible. An experiment of this kind was both repeated and replicated, using a previously studied Drosophila melanogaster population. The results uniformly corroborated the evolutionary theory of senescence. Senescence was consistently postponed. Other, anomalous, results are explained in terms of experimental artifact.
