在过去的十年中，人们对了解微生物合作行为的多样性产生了极大的兴趣，包括交流，群体为基础的蜂群，子实体的形成，以及群体有益酶和食物清除分子的分泌。Zhang和Rainey（以下简称为Z&R）最近认为，社会微生物学家过于热衷于将微生物视为内在的社会有机体，而在社会进化框架中解释微生物的行为又过于草率。这一挑战伴随着一系列实验，在这些实验中，他们重新审视了细菌中研究得最好的社会行为之一——产生可扩散的、可共享的清除铁的铁载体分子。Z&R认为，他们的发现挑战了铁载体生产是一种合作特性的观点。在这里，我们证明他们的论点是有缺陷的，并且源于技术错误和对社会进化论的误解。
Over the past decade, there has been enormous interest in understanding the great diversity of microbial cooperative behaviors, including communication, group-based swarming, fruiting-body formation, and the secretion of group-beneficial enzymes and food-scavenging molecules. Zhang and Rainey, henceforth Z&R, recently contended that sociomicrobiologists have been overzealous in their casting of microbes as inherently social organisms, and too hasty in interpreting microbial behaviors in a social evolutionary framework. This challenge accompanied a set of experiments in which they revisited one of the best-studied social behaviors in bacteria-the production of diffusible, sharable iron-scavenging siderophore molecules. Z&R posit that their findings challenge the view that siderophore production is a cooperative trait. Here, we demonstrate that their arguments are flawed, and stem from both technical mistakes and misunderstandings of social evolution theory.
