当雌性乱交时，竞争的雄性会竞争使卵子受精。从理论上讲，雄性可以通过诱导雌性产更多的卵，以及产生更具竞争力的精子来增加他繁殖后代的成功率。在这里，我们报告说，生殖力刺激的进化后果超出了竞争对手的男性，通过实验揭示对后代的影响。通过对埋葬虫Nicrophorus vespilloides的实验，我们发现较小的从属雄性比较大的占主导地位的雄性更能刺激雌性生殖力。此外，占主导地位的雄性也受益于较小的雄性诱导的更大的繁殖力，因此从雌性早期的滥交中获益-正如理论所预测的那样。通过诱导雌性在有限的资源上产生更多的后代，较小的雄性会导致每个幼虫变小，即使是那些它们自己没有繁殖的幼虫。因此，生殖刺激促进了后代体型的非遗传遗传，并为后代遗传提供了一种机制。
When females mate promiscuously, rival males compete to fertilise the ova. In theory, a male can increase his success at siring offspring by inducing the female to lay more eggs, as well as by producing more competitive sperm. Here we report that the evolutionary consequences of fecundity stimulation extend beyond rival males, by experimentally uncovering effects on offspring. With experiments on the burying beetle Nicrophorus vespilloides, we show that smaller subordinate males are better able to stimulate female fecundity than larger, dominant males. Furthermore dominant males also benefit from the greater fecundity induced by smaller males, and so gain from the female's earlier promiscuity ‐ just as predicted by theory. By inducing females to produce more offspring on a limited resource, smaller males cause each larva to be smaller, even those they do not sire themselves. Fecundity stimulation thus promotes the non‐genetic inheritance of offspring body size, and provides a mechanism for telegony.
