The evolution of soldier reproduction in ..
The presence of reproductively altruistic castes is one of the primary traits of the eusocial societies. Adaptation and regulation of the sterile caste, to a certain extent, drives the evolution of eusociality. Depending on adaptive functions of the first evolved sterile caste, eusocial societies can be categorized into the worker-first and soldier-first lineages, respectively. The former is marked by a worker caste as the first evolved altruistic caste, whose primary function is housekeeping, and the latter is highlighted by a sterile soldier caste as the first evolved altruistic caste, whose task is predominantly colony defense. The apparent functional differences between these two fundamentally important castes suggest worker-first and soldier-first eusociality are potentially driven by a suite of distinctively different factors. Current studies of eusocial evolution have been focused largely on the worker-first Hymenoptera, whereas understanding of soldier-first lineages including termites, eusocial aphids, gall-dwelling thrips, and snapping shrimp, is greatly lacking. In this review, we summarize the current state of knowledge on biology, morphology, adaptive functions, and caste regulation of the soldier caste. In addition, we discuss the biological, ecological and genetic factors that might contribute to the evolution of distinct caste systems within eusocial lineages.

Despite the fact that both soldiers and workers exhibit reproductive altruism, the two castes are distinct in their adaptive functions. Current debates regarding how genetics and ecological factors contribute to the development of eusociality primarily focus on how these factors contribute to the evolution of altruistic helping(why to help), whereas the remarkable functional differences (how to help) between the two castes are not sufficiently considered. Although it has been demonstrated in many lineages that genetic relatedness might contribute to evolution of altruism in both worker-first and soldier-first lineages, little genetic correlation has been found to explain distinct caste distribution in worker-first and soldier-first lineages. However, a comparison between worker-first and soldier-first lineages suggests the presence of strong ecological and biological correlations for such differences. Therefore, while eusocial evolution could be attributed to both genetic and ecological factors, the function and distribution of altruistic castes are primarily shaped by the latter.
