This situation is changed at stage 20 (Fig. 6); in the central region, retina and pigment epithelium temporarily have a negative radius of curvature. In this region the formation of the choroid is most advanced; many mitoses can be seen in the central retina while they decrease rapidly towards the periphery.

Therefore, we should be able to find immediate conditions, dependencies and rules determining the development of an organic form. With this in mind, His (1874) defined the task of embryology as follows: “Developmental biology is essenti

The lens epithelium forms a pit which is open towards the body surface. At stage 18 (only 15 hours later) the edges of the lens have come together and fused. The lens now for
