| 摘 要： | 头索动物文昌鱼是现存的最接近脊椎动物的无脊椎动物,它的形体结构简单却具有脊索动物的基本特征,而且其没有经过大规模复制的基因组结构与脊椎动物的始祖很接近。文昌鱼占据着重要的进化地位,并且长期以来在进化生物学和发育生物学等研究领城中一直作为模式动物,本文从文昌鱼的发现、形态结构、物种及分布、生活习性和胚胎发育等方面作以阐述。

| Abstract: | The cephalochordate amphioxus is the closest living relative to the vertebrates, with a simple chordate body plan, and a genome lacking the large-scale gene duplications, most closely approximates to that of the last common ancestor of all vertebrates. It possesses an important evolutional status and has long been regarded as the model animal for insight into the evolutionary biology and developmental biology. Here we provide a detailed review of the discovery history of amphioxus body plan, category, distribution region, living habit and their embryonic development. |
