脊椎动物身体结构的进化起源：头部 segmentation 的问题。 注：这里“segmentation”在生物学领域可能有特定专业含义，比如“体节形成”等，需结合具体文献进一步准确理解其确切所指。

The basic body plan of vertebrates, as typified by the complex head structure, evolved from the last common ancestor approximately 530 Mya. In this review, we present a brief overview of historical discussions to disentangle the various concepts and arguments regarding the evolutionary development of the vertebrate body plan. We then explain the historical transition of the arguments about the vertebrate body plan from merely epistemological comparative morphology to comparative embryology as a scientific treatment on this topic. Finally, we review the current progress of molecular evidence regarding the basic vertebrate body plan, focusing on the link between the basic vertebrate body plan and the evolutionarily conserved developmental stages (phylotypic stages).
脊椎动物的基本身体结构，以复杂的头部结构为代表，大约在5.3亿年前从最后的共同祖先演化而来。在这篇综述中，我们简要概述了历史上的讨论，以厘清关于脊椎动物身体结构进化发展的各种概念和论点。然后，我们解释了关于脊椎动物身体结构的论点从仅仅是认识论的比较形态学向作为该主题科学研究方法的比较胚胎学的历史转变。最后，我们回顾了关于脊椎动物基本身体结构的分子证据的当前进展，重点关注脊椎动物基本身体结构与进化上保守的发育阶段（系统发育阶段）之间的联系。
