The timing of some key embryological events is given for man, rat, chick, and certain other animals. Such times, however, are approximations, and variations occur among members of the same strain and even among members of the same litter. Some differences in developmental patterns are indicated.
文中给出了人类、大鼠、鸡以及某些其他动物一些关键胚胎学事件的发生时间。然而，这些时间只是近似值，同一品系的个体之间甚至同一窝的个体之间都会存在差异。文中还指出了发育模式上的一些差异。
