Options

A. Darwin finches show convergent evolution .
B. Home erectus evolved earlier than Homo sapiens .
C. Home sapiens appeared in African grassland
D. Archaeopteryx is connecting link between the birds and reptiles .

Answer

To solve the question of identifying the incorrect statement among the provided options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze the First Statement:**
- **Statement:** "Darwin finches show convergent evolution."
- **Explanation:** Darwin finches are an example of adaptive radiation, which is a form of divergent evolution. They evolved from a common ancestor into various species with different beak shapes adapted to their specific feeding habits. Therefore, this statement is incorrect as it misclassifies the type of evolution.

2. **Analyze the Second Statement:**
- **Statement:** "Homo erectus evolved earlier than Homo sapiens."
- **Explanation:** This statement is correct. Homo erectus is indeed an earlier species in the human evolutionary timeline, preceding Homo sapiens.

3. **Analyze the Third Statement:**
- **Statement:** "Homo sapiens appeared in African grassland."
- **Explanation:** This statement is also correct. Fossil evidence supports that Homo sapiens originated in Africa, and the grassland environment is consistent with the habitats where early humans lived.

4. **Analyze the Fourth Statement:**
- **Statement:** "Archaeopteryx is a connecting link between the birds and the reptiles."
- **Explanation:** This statement is correct. Archaeopteryx is widely recognized as a transitional fossil that exhibits characteristics of both birds and reptiles, thus serving as a connecting link.

### Conclusion:
After analyzing all the statements, the incorrect statement is the first one: "Darwin finches show convergent evolution."
