衰老的群体遗传学理论的一个一般推论是，使用较晚年龄的雌性进行远交实验室种群的培养应该导致延缓衰老的进化。这之前已经过测试，但预测结果并不是一致的可重复性。这类实验被重复和复制，使用的是之前研究过的黑腹果蝇种群。这些结果一致地证实了衰老的进化论。衰老一直被推迟。另一些反常的结果则用实验伪像来解释。
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 D. 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.
