一个多世纪以来，节肢动物内的系统发育关系一直存在争议。今天，关于神经系统结构和发育的比较研究为这一讨论提供了重要的论据，因此“神经系统发育学”一词是为该学科创造的。最近对各种非模型节肢动物神经系统的大量研究表明，我们在深入分析节肢动物神经系统细胞结构的过程中取得了很大进展，最终将提供与形态学系统发育研究中传统使用的特征相同甚至更好的分辨率水平的特征。本文旨在总结节肢动物系统发育学讨论的现状，并简要评估已被用作支持传统气管动物假说的论据的形态特征。然后，从细胞水平到更大的神经纤维系统水平，对节肢动物大脑和腹神经索的结构和发育的特征进行了全面的概述。这些特征支持了多尔提出的新的四足亚目假说，并为将软甲纲、唇足类甲壳类动物与六足动物统一起来的进化枝提供了证据。
The phylogenetic relationships within the Arthropoda have been controversial for more than a century. Today, comparative studies on the structure and development of the nervous system contribute important arguments to this discussion, so that the term "neurophylogeny" was coined for this discipline. The large number of recent studies on the nervous system in various nonmodel arthropods indicates that we are far advanced in the process of analyzing the cellular architecture of the arthropod nervous system in a depth that will ultimately provide characters at a level of resolution equal or even superior to that of characters traditionally used in morphological phylogenetic studies. This article sets out to summarize the current state of the discussion on arthropod phylogeny and briefly evaluates the morphological characters that have been used as arguments in favor of the traditional Tracheata hypothesis. Then, a thorough over-view is given of characters derived from structure and development of the arthropod brain and the ventral nerve cord from the cellular level to the level of larger neuropil systems. These characters support the new Tetraconata hypothesis suggested by Dohle and provide evidence for a clade that unites malacostracan and remipede crustaceans with the Hexapoda.
