Remak is the second great name in the history of the germ-layer theory.
He it was who introduced the terms "Keimhaut" (blastoderm) and "Keimblatt" (germ-layer).
In his germ-layer theory Remak's standpoint is histological 212rather than morphological.
He used the germ-layer theory to prove the essential unity of type of all the Triploblastica.
If the germ-layer theory is no longer credited, upon what fundamental laws is embryology based?
In this manner the foundations of the germ-layer theory were established in their modern form.
