The second major event in animal development is Gastrulation. Here is a step-by-step breakdown of the major events:

1. Fertilization: This is the first major event in animal development. It involves the fusion of the sperm and egg cells to form a zygote.

2. Gastrulation: This is the second major event. During gastrulation, the cells of the blastula rearrange themselves into a three-layered structure called the gastrula.

3. Organogenesis: This is the third major event. During organogenesis, the three germ layers developed during gastrulation develop into the internal organs of the organism.

4. Cleavage: This is actually not a major event in development, but a stage of early embryogenesis following fertilization and preceding gastrulation. During cleavage, the zygote undergoes rapid cell division without growth to form a multicellular structure called a blastula.
