Whether or not bacteria have species is a perennially vexatious question. Given what we now know about variation among bacterial genomes, we argue that there is no intrinsic reason why the processes driving diversification and adaptation must produce groups of individuals sufficiently coherent in their genetic and phenotypic properties to merit the designation 'species'--although sometimes they might.
细菌是否存在物种是一个长期困扰人的问题。鉴于我们目前对细菌基因组变异的了解,我们认为,驱动分化和适应的过程必然会产生在遗传和表型特征上足够一致、值得被称为“物种”的个体群体,这并没有内在原因——尽管有时可能会这样。
