我分析了一些普遍存在的关于物种的误解。物种类别由一个概念定义，表示物种分类单元在林奈等级中的等级。生物物种的繁殖是相互隔离的，这保护了它们基因类型的完整性。形态差异的程度不是一个合适的物种定义。不同特征进化速度的不平等和缺乏关于孤立种群交配潜力的信息是划分物种分类群的主要困难。
I analyze a number of widespread misconceptions concerning species. The species category, defined by a concept, denotes the rank of a species taxon in the Linnaean hierarchy. Biological species are reproducing isolated from each other, which protects the integrity of their genotypes. Degree of morphological difference is not an appropriate species definition. Unequal rates of evolution of different characters and lack of information on the mating potential of isolated populations are the major difficulties in the demarcation of species taxa.
