Two processes suggested to drive bacterial speciation - periodic selection and recombination - are generally thought to be mutually opposed. Recent work shows that data taken as evidence supporting the former may be explained by the latter, raising further problems for the idea of bacterial 'species'.
有两个被认为相互矛盾的过程被认为可以驱动细菌的物种形成——周期性选择和重组。最近的研究表明，被认为支持前者的证据数据可以用后者来解释，这给细菌“物种”的概念带来了更多的问题。
