What is adaptive radiation ? When can adaptive radiation be referred to as convergent evolution ? Give an example.

Explanation

### Step-by-Step Solution:

1. **Definition of Adaptive Radiation**:
- Adaptive radiation is a process of evolution where organisms diversify rapidly from an ancestral species into a wide variety of forms to adapt to different environments. It typically begins from a single point (a common ancestor) and radiates outwards into various niches.

2. **Conditions for Adaptive Radiation to be Considered Convergent Evolution**:
- Adaptive radiation can be referred to as convergent evolution when multiple adaptive radiations occur in isolated geographical areas. In this scenario, different species evolve similar traits or adaptations independently due to similar environmental pressures, despite having different ancestral origins.
