The three germinal layers differentiate during the process of Gastrulation.

Explanation:
Gastrulation is a crucial process in early embryonic development, during which the blastula (a hollow ball of cells) is transformed into a three-layered structure called the gastrula. The three germinal layers - the endoderm, mesoderm, and ectoderm - differentiate during this process.

• Endoderm: The endoderm is the innermost layer and gives rise to the lining of the digestive and respiratory tracts, as well as some organs such as the liver and pancreas.

• Mesoderm: The mesoderm is the middle layer and gives rise to the muscles, bones, kidneys, and reproductive organs.

• Ectoderm: The ectoderm is the outermost layer and gives rise to the skin, nervous system, and sensory organs.

During gastrulation, the cells in the blastula undergo a series of complex movements, resulting in the formation of the three germinal layers. This process is regulated by a variety of signaling molecules and genetic factors.

In summary, the three germinal layers differentiate during the process of gastrulation, which is a critical stage in early embryonic development.
