Which one provides direct and solid evidence in favour of organic evolution through ages `?`

Options

A. Atavism
B. Palaeontology
C. Vestigeal organs
D. Galapagos island fauna

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks which option provides direct and solid evidence in favor of organic evolution through ages. This implies that we need to identify a concept or field that offers concrete proof of how life forms have changed over time.

2. **Analyzing the Options**:
- **Atavism**: This refers to the reappearance of ancestral traits in an organism. While it can show how traits can re-emerge, it does not provide direct evidence of the overall process of evolution.
- **Paleontology**: This is the study of fossils and ancient life forms. Fossils are key pieces of evidence that show how organisms have changed over time, making paleontology a strong candidate for providing solid evidence of organic evolution.
- **Vestigial Organs**: These are organs that have lost their original function through evolution. While they can indicate evolutionary history, they do not provide direct evidence of the process itself.
- **Galapagos Islands Fauna**: The unique species found here contributed to Darwin’s theory of evolution, but it does not serve as direct evidence of evolution through ages.

3. **Identifying the Correct Answer**: Among the options provided, paleontology stands out as it directly involves the study of fossils, which are the most concrete evidence of organic evolution over time. Therefore, the correct answer is **Paleontology**.

4. **Conclusion**: The solid evidence in favor of organic evolution through ages is best represented by the study of fossils, which is encompassed in paleontology.

**Final Answer**: Paleontology
