物种问题，尽管经过了几十年的激烈争论，至今仍未得到解决。最近，两个新的物种概念已经出版，mitochondrial兼容性物种概念和包容性物种概念。我简要地讨论他们，连同最近的尝试，在更广泛的框架，我相信是一个固有的限制分类学强加一个离散系统的连续过程（进化），导致模糊的边界在性质上的分类决策标准化。有鉴于此，分类学家、一般生物学家和自然资源保护主义者都必须接受这样一个事实，即完全非任意的物种划分是不可能的。这对所有依赖物种的学科都有严重的影响，特别是物种计数，作为定量分析（生态学，进化生物学）和实际决策（保护和环境政策）的基本货币。
The species problem, despite decades of heated debates, has not been resolved yet. Recently, two new species concepts have been published, the mitonuclear compatibility species concept and the inclusive species concept. I briefly discuss them, together with a recent attempt at standardizing taxonomic decisions, in the broader framework of what I believe is an inherent limitation of taxonomy—imposing a discrete system on a continuous process (evolution) that leads to fuzzy boundaries in nature. In the light of this, taxonomists, biologists in general and conservationists alike will have to accept the fact that completely nonarbitrary species delimitation is impossible. This has serious ramifications in all disciplines that rely on species, and particularly species counts, as a basic currency for quantitative analyses (ecology, evolutionary biology) and practical decision-making (conservation and environmental policy).
