不同生物之间的系统发育重建不仅有助于理解它们的进化史，还揭示了几个基本的进化问题。对生物体之间进化关系的理解为其他生物学学科的研究奠定了基础。然而，几乎所有广泛使用的系统发育方法都有局限性，无法有效消除系统误差，阻碍真正的生物关系的重建。“长枝吸引”(LBA)伪影是系统发育重建中最具干扰性的因素之一。本文对LBA的概念、分析方法以及规避策略进行了综述。此外，还给出了几个典型的算例。讨论了避免和解决LBA伪影的方法。
Phylogenetic reconstruction among various organisms not only helps understand their evolutionary history but also reveal several fundamental evolutionary questions. Understanding of the evolutionary relationships among organisms establishes the foundation for the investigations of other biological disciplines. However, almost all the widely used phylogenetic methods have limitations which fail to eliminate systematic errors effectively, preventing the reconstruction of true organismal relationships. "Long-branch Attraction" (LBA) artifact is one of the most disturbing factors in phylogenetic reconstruction. In this review, the conception and analytic method as well as the avoidance strategy of LBA were summarized. In addition, several typical examples were provided. The approach to avoid and resolve LBA artifact has been discussed.
