Which is CORRECT regarding convergent evolution?

Options

A. Convergent evolution indicates common ancestry
B. Thorn of Bougainvillea and tendrils of Cucurbita are examples of convergent evolution
C. Selection of similar adaptive features in different groups of organisms but towards the same function is convergent evolution.
D. Homologous organs are result of convergent evolution.

Answer

To solve the question regarding convergent evolution, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Convergent Evolution**:
- Convergent evolution is a process where organisms from different evolutionary backgrounds develop similar traits or functions. This occurs because they adapt to similar environments or ecological niches, leading to analogous structures.

2. **Identifying Key Characteristics**:
- In convergent evolution, the structures involved are not anatomically similar (they do not share a common ancestor) but serve similar functions. These structures are referred to as **analogous structures**.

3. **Evaluating the Statements**:
- We need to analyze the provided statements about convergent evolution:
- **Statement 1**: Convergent evolution indicates common ancestry.
- **Evaluation**: This is incorrect. Common ancestry is indicated by divergent evolution, not convergent evolution.
- **Statement 2**: Thorn of Poggenveliae and Tendrils of Cucurbita are examples of convergent evolution.
- **Evaluation**: This is also incorrect. These are examples of divergent evolution, as they have a common ancestor.
- **Statement 3**: Selection of similar adaptive features in different groups of organisms but towards the same function is convergent evolution.
- **Evaluation**: This statement is correct. It accurately describes the essence of convergent evolution.
- **Statement 4**: Homologous organs are a result of convergent evolution.
- **Evaluation**: This is incorrect. Homologous organs arise from divergent evolution, not convergent evolution.

4. **Conclusion**:
- The correct statement regarding convergent evolution is the third one: "Selection of similar adaptive features in different groups of organisms but towards the same function is convergent evolution."

### Final Answer:
The correct statement regarding convergent evolution is: "Selection of similar adaptive features in different groups of organisms but towards the same function is convergent evolution."
