硬骨鱼的成对鳍和四足脊椎动物的四肢肌肉发育的进化史在很大程度上仍然是不确定的。然而，已有共识认为，在脊椎动物分支中，鳍和四肢肌肉发育的祖先机制涉及上皮组织从体节延伸到鳍/肢芽。这一机制已经在软骨类、双节类、软骨类和硬骨鱼中得到了证明，也被认为在羊膜动物中，肌肉的单个祖细胞从体节迁移到肢芽中。不，不是的。现在提出了一个令人兴奋的发现，即斑马鱼中存在这种可能与单个细胞迁移有关的衍生机制。基于鲨鱼、斑马鱼、鸡、鹌鹑和老鼠的数据，他们得出结论，认为这种派生机制存在于石棺龙中，然而，根据文献中提供的进一步数据，这一结论可能为时过早，这些数据显示，这种特征在脊椎动物分支中高度镶嵌分布，此外，在硬骨鱼、爬行动物和可能的两栖动物中，存在一种介于假定的祖先模式和派生模式之间的发育模式。(C)2001年John Wiley&Sons，Inc.
The evolutionary history of muscle development in the paired fins of teleost fish and the limbs of tetrapod vertebrates is still, to a large extent, uncertain. There has been a consensus, however, that in the vertebrate clade the ancestral mechanism of fin and limb muscle development involves the extension of epithelial tissues from the somite into the fin/limb bud. This mechanism has been documented in chondrichthyan, dipnoan, chondrostean and teleost fishes, It has also been assumed that in amniotes, in contrast, individual progenitor cells of muscles migrate from the somites into the limb buds. Neyt et at. now present the exciting finding that in zebrafishes this presumably derived mechanism involving individual cell migration, is present. They conclude, based on data on sharks, zebrafishes, chickens, quails and mice that the derived mechanism was present in the sarcopterygians, This conclusion, however, may be premature in the light of further data available in the literature, which show a highly mosaic distribution of this character in the vertebrate clade, Furthermore, a developmental mode exists that is intermediate between the supposed ancestral and derived modes in teleosts, reptiles and possibly amphibians.
