鱼类-四足动物的转变是脊椎动物进化中的主要事件之一，许多形态变化使其成为可能。尽管近年来从古生物学和比较发育的角度来看，配对鱼鳍转变为四足动物肢体一直是一个主要的研究主题，但人们的兴趣几乎完全集中在附肢的远端部分，特别是脚趾的起源。对于骨盆腰带从一个小的一部分结构到一个大的三部分承重结构的转变，相对较少的关注，使得四足动物主要依靠后肢来运动。为了了解在这一转变过程中坐骨和髂骨是如何进化的，以及髋臼是如何重新定位的，我们对澳大利亚肺鱼Neoceratodus forsteri和墨西哥Axolotl ambystoma micianum的生长系列进行了清除，并对软骨和骨骼进行了染色，对骨骼肌进行了免疫染色。为了了解肌肉发育的数据，根据腔棘鱼(Latimeria)、澳大利亚肺鱼(Neoceratodus)和火蜥蜴(Necturus)的文献描述，提出了关于Latimeria、Neoceratodus和Necturus成虫盆部肌肉同源性的假设。在Axolotl和肺鱼中，骨盆带的软骨化始于髋臼，在肺鱼中向前发展，在火蜥蜴中向前和向后发展。髂骨向背侧延伸，与枢椎肋骨相遇，并与之相连。同种肌肉的发育顺序相同，先发育下轴肌，然后是深肌，然后是盆浅肌。新角化症和间囊瘤的骨盆内骨骼和肌肉系统的发育非常相似。如果髋臼被视为一个固定的地标，坐骨的进化只需要耻骨前软骨形成细胞向后迁移。据推测，大多数四足形鱼类的髂突或脊部是四足类髂骨的前身，其进化过程与现代火蜥蜴的发育过程相似。
The fish-tetrapod transition was one of the major events in vertebrate evolution and was enabled by many morphological changes. Although the transformation of paired fish fins into tetrapod limbs has been a major topic of study in recent years, both from paleontological and comparative developmental perspectives, the interest has focused almost exclusively on the distal part of the appendage and in particular the origin of digits. Relatively little attention has been paid to the transformation of the pelvic girdle from a small unipartite structure to a large tripartite weight-bearing structure, allowing tetrapods to rely mostly on their hindlimbs for locomotion. In order to understand how the ischium and the ilium evolved and how the acetabulum was reoriented during this transition, growth series of the Australian lungfish Neoceratodus forsteri and the Mexican axolotl Ambystoma mexicanum were cleared and stained for cartilage and bone and immunostained for skeletal muscles. In order to understand the myological developmental data, hypotheses about the homologies of pelvic muscles in adults of Latimeria, Neoceratodus and Necturus were formulated based on descriptions from the literature of the coelacanth (Latimeria), the Australian Lungfish (Neoceratodus) and a salamander (Necturus). In the axolotl and the lungfish, the chondrification of the pelvic girdle starts at the acetabula and progresses anteriorly in the lungfish and anteriorly and posteriorly in the salamander. The ilium develops by extending dorsally to meet and connect to the sacral rib in the axolotl. Homologous muscles develop in the same order with the hypaxial musculature developing first, followed by the deep, then the superficial pelvic musculature. Development of the pelvic endoskeleton and musculature is very similar in Neoceratodus and Ambystoma. If the acetabulum is seen as being a fixed landmark, the evolution of the ischium only required pubic pre-chondrogenic cells to migrate posteriorly. It is hypothesized that the iliac process or ridge present in most tetrapodomorph fish is the precursor to the tetrapod ilium and that its evolution mimicked its development in modern salamanders.
