本文对节肢动物的系统发育、形态学和发育资料进行了综述和讨论，目的是重建下颌骨节肢动物（多足、六足、甲壳纲）的祖先形体计划。malacostracans和六足动物的比较形态学和胚胎学（细胞系、有丝分裂结构域模式、条纹形成模式、配对规则、同型异体和间隙样基因的表达区）表明：(a)将下颌骨体细分为初级胚胎区域（前头原体和后原球茎）的基本边界位于副节PS1的前面（=在下颌骨段内）；(b)头原体（孕区）可能不是一个单一的身体区域；(c)上颌节段与颌后干节段密切相关；(d)“典型的”下颌骨头部（妊娠-下颌-上颌）并不是在所有的下颌骨中发育的，而是平行进化了好几次的；(e)头后tagmosis比前区tagmosis更不保守，可能是最近发生的。前异网膜瘤，即原体，与假设的祖先下颌骨头部进行比较。
Phylogenetic, morphological, and developmental data concerning the Arthropoda are reviewed and discussed with the aim of reconstructing the ancestral body plan of the mandibulate arthropods (Myriapoda, Hexapoda, Crustacea). Comparative morphology as well as embryology of malacostracans and hexapods (cell‐lineages, patterns of mitotic domains, patterns of en‐stripe formation, expression zones of pair‐rule, homeotic, and gap‐like genes) suggest that (a) the basic boundary subdividing the mandibulate body into the primary embryonic regions, anterior protocephalon and posterior protocorm, runs anteriorly to parasegment PS1 (=within the mandibular segment); (b) protocephalon (pregnathal region) probably is not a unitary body region; (c) maxillary segments are closely related to the postgnathal trunk segments; (d) the “typical” mandibulate head (pregnathal‐mandibular‐maxillary) is not developed in all Mandibulata and has evolved several times in parallel; and (e) postcephalic tagmosis is much less conserved, and probably more recent, than tagmosis of more anterior areas. The arachnomorphan anterior tagma, the prosoma, is compared with the hypothesized ancestral mandibulate head.
