When more than one adaptive radiations appeared to have occured in an isolated geographical area (representing different habitats). One call this

Answer

**Step-by-Step Solution:**

1. **Understanding Adaptive Radiation**:
- Adaptive radiation refers to the process where organisms diversify rapidly into a variety of forms to adapt to different environments. This typically occurs when a species colonizes a new area with diverse habitats.

2. **Identifying the Context**:
- The question specifies that more than one adaptive radiation has occurred in an isolated geographical area. This implies that different species have adapted to various habitats within the same isolated location.

3. **Recognizing the Key Concept**:
- The key concept here is that these species do not share a common ancestor but have developed similar traits due to the similar environmental pressures they face in their respective habitats.

4. **Defining the Phenomenon**:
- When multiple species from different ancestral backgrounds evolve similar traits in response to similar environmental challenges, this phenomenon is termed "convergent evolution."

5. **Conclusion**:
- Therefore, when more than one adaptive radiation occurs in an isolated geographical area, it is referred to as "convergent evolution."

**Final Answer**: Convergent evolution.
