Abstract
Now that the genes controlling embryonic patterning have been identified in several model organisms, long-standing questions concerning the evolution of developmental systems are open to investigation. Examination of the expression of even-skipped in a variety of insects reveals that Insect germ-type designations apparently do not reflect the variations in the mechanisms of segmentation evident throughout insect phylogeny.
摘要
既然已经在几种模式生物中鉴定出了控制胚胎模式形成的基因，那么关于发育系统进化的长期问题就有待研究了。对多种昆虫中even-skipped基因表达的研究表明，昆虫的胚型划分显然并不能反映整个昆虫系统发育过程中明显的体节形成机制的差异。
