What is peculiar about the development of frog?

Explanation

### Step-by-Step Solution:

1. **Understanding Frog Development**: Frogs undergo a unique developmental process that includes distinct life stages, starting from eggs to tadpoles and then to adult frogs.

2. **Tadpole Stage**: The larval stage of frogs is known as the tadpole. Tadpoles are aquatic and have a fish-like appearance, characterized by a tail and gills for breathing underwater. This stage indicates that frogs share a common ancestry with fish.

3. **Evolutionary Significance**: The presence of a fish-like tail in tadpoles suggests that frogs have evolved from fish. This is a significant evolutionary trait that highlights the transition from aquatic to terrestrial life.
