Although the problem of speciation is a puzzle for evolutionists, species are not mere fantasies. In many cases, it is possible to identify evolutionary entities that deserve to be attributed the name 'species' and that are relevant to medical researchers and decision makers. All approaches to the problem of speciation in pathogens are specific cases of four main concepts (or combinations thereof): biological, phylogenetic, phenetic and phenotypic. Modern genetic concepts and technologies help to juggle these concepts.
虽然物种形成问题对进化论者来说是个难题，但物种并非纯粹的幻想。在许多情况下，有可能识别出那些值得被赋予“物种”之名且与医学研究人员和决策者相关的进化实体。病原体物种形成问题的所有研究方法都是四个主要概念（或其组合）的具体实例：生物学概念、系统发育概念、表型分类概念和表型概念。现代遗传学概念和技术有助于协调这些概念。
