社会生物学的一个基本目标是解释复杂的社会行为是如何进化的(1)，特别是在社会生活的典范--社会昆虫中。虽然仍有很多争议的主题(2)，但最近的理论解释集中在工人行为的进化起源(来自留在巢中的女儿的帮助，并帮助她们的母亲生育)，通过表达母亲对兄弟姐妹的照顾行为(3，4)。这一进化模型的一个关键预测是，涉及母性照料的特征通过母性基因的异时性表达而被增选(5)，从而产生兄弟姐妹照料，这是昆虫高度进化的社会生活的标志(6)。母性行为与生殖状态的结合是在独居昆虫中进化的，是工蚁社会进化的现成基础(3，4，7，8)。在这里，我们表明，工蜂(蜜蜂)之间觅食劳动的分工与兼性不育雌性的生殖状态有关。因此，我们确定了一种广泛表达的社会-昆虫行为综合症(1，5，7，9)的进化起源，并提供了关于母亲生殖特征的变异如何导致非生殖帮助者复杂的社会行为的直接演示。
A fundamental goal of sociobiology is to explain how complex social behaviour evolves(1), especially in social insects, the exemplars of social living. Although still the subject of much controversy(2), recent theoretical explanations have focused on the evolutionary origins of worker behaviour ( assistance from daughters that remain in the nest and help their mother to reproduce) through expression of maternal care behaviour towards siblings(3,4). A key prediction of this evolutionary model is that traits involved in maternal care have been co-opted through heterochronous expression of maternal genes(5) to result in sib-care, the hallmark of highly evolved social life in insects(6). A coupling of maternal behaviour to reproductive status evolved in solitary insects, and was a ready substrate for the evolution of worker-containing societies(3,4,7,8). Here we show that division of foraging labour among worker honey bees ( Apis mellifera) is linked to the reproductive status of facultatively sterile females. We thereby identify the evolutionary origin of a widely expressed social-insect behavioural syndrome(1,5,7,9), and provide a direct demonstration of how variation in maternal reproductive traits gives rise to complex social behaviour in non-reproductive helpers.
