物种之间缺乏明显的形态差异，阻碍了许多生物体群体中物种的鉴定。与此同时，基于DNA的方法越来越多地被用于调查生物多样性。在这项研究中，我们对西部古北区534只蝙蝠的线粒体蛋白编码基因NADH脱氢酶1亚单位(ND1)进行了测序，在两个主要方面证实了DNA条形码的前景。首先，用经典分类学工具描述的物种可以从基因上识别，只有少数几个例外。其次，巨大的序列差异表明，未被发现的物种数量出人意料地高。
The lack of obvious morphological differences between species impedes the identification of species in many groups of organisms. Meanwhile, DNA-based approaches are increasingly used to survey biological diversity. In this study we show that sequencing the mitochondrial protein-coding gene NADH dehydrogenase, subunit 1 (nd1) from 534 bats of the Western Palaearctic region corroborates the promise of DNA barcodes in two major respects. First, species described with classical taxonomic tools can be genetically identified with only a few exceptions. Second, substantial sequence divergence suggests an unexpected high number of undiscovered species.
