The fate of germ layers is the same in all triploblastic animals. Why?

Explanation

### Step-by-Step Solution:

1. **Understanding Triploblastic Animals**:
- Triploblastic animals are those that develop from three primary germ layers: ectoderm, mesoderm, and endoderm. These layers are formed during embryonic development.

2. **Identifying the Germ Layers**:
- **Ectoderm**: This is the outermost layer and is responsible for forming the epithelial and neural tissues.
- **Mesoderm**: This is the middle layer and gives rise to structures such as skeletal muscle, bone, and connective tissues.
