Description
The process of gastrulation allows for the formation of the germ layers in metazoan embryos, and is generally achieved through a series of complex and coordinated cellular movements. The process of gastrulation can be either diploblastic or triploblastic. In diploblastic organisms like cnidaria or ctenophora, only the endoderm and the ectoderm form; in triploblastic organisms (most other complex metazoans), triploblastic gastrulation produces all three germ layers. The gastrula, the product of gastrulation, was named by Ernst Haeckel in the mid-1870s; the name comes from Latin, where gaster means stomach, and indeed the gut (archenteron) is one of the most distinctive features of the gastrula.
