兄弟姐妹的合作育雏护理，真社会性的一个定义特征，被假设为是从进化上派生的孕产妇护理通过转移的时间表达的基因基础孕产妇护理。如果兄弟姐妹和母亲的照顾共享遗传基础，这两种行为预计将在遗传和表型相关。我们测试了这一预测在黑蚂蚁Lasius尼日尔花园通过量化的育雏率的皇后和他们的第一代和后代工人的后代。蚁后取卵率与第一代工蜂取卵率呈显著正相关，与后代工蜂取卵率无显著相关。第一代工蚁和第二代工蚁之间的差异可能是由于蚁后和第一代工蚁提供的照料行为与后代相比具有更强的相似性。此外，我们发现，女王检索率与殖民地生产力呈正相关，这表明自然选择是作用于母亲的照顾。总体而言，我们的结果支持了孕产妇和兄弟姐妹护理以及更普遍的蜂王和工蜂特征之间存在共同遗传基础的观点，这对种姓间相关性在蜂王和工蜂特征以及正常社会性的进化中的作用具有影响。
Cooperative brood care by siblings, a defining feature of eusociality, is hypothesized to be evolutionarily derived from maternal care via shifts in the timing of the expression of genes underlying maternal care. If sibling and maternal care share a genetic basis, the two behaviors are expected to be genetically and phenotypically correlated. We tested this prediction in the black garden ant Lasius niger by quantifying the brood retrieval rate of queens and their first and later generation worker offspring. Brood retrieval rate of queens was positively phenotypically correlated with the brood retrieval rate of first generation but not with later generation workers. The difference between first and later generation workers could be due to the stronger similarity in care behavior provided by queens and first generation workers compared to later generations. Furthermore, we found that queen retrieval rate was positively correlated with colony productivity, suggesting that natural selection is acting on maternal care. Overall, our results support the idea of a shared genetic basis between maternal and sibling care as well as queen and worker traits more generally, which has implications for the role of intercaste correlations in the evolution of queen and worker traits and eusociality.
