Which of the following is the most evident source of evolution

Options

A. Fossils
B. Morphology
C. Embryo
D. Vestigial organs

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the most evident source of evolution among the given options: fossils, morphology, embryo, or vestigial organs.

2. **Analyzing the Options**:
- **Fossils**: These are the preserved remains of organisms from the past. They provide direct evidence of the existence of different species over time and allow scientists to study the changes in species and their structures.
- **Morphology**: This refers to the study of the form and structure of organisms. While morphology can provide insights into evolutionary relationships, it is not as direct as fossil evidence.
- **Embryo**: The study of embryos can show similarities between species, but it does not provide a clear picture of evolutionary history on its own.
- **Vestigial Organs**: These are organs that have lost their original function through evolution. While they can indicate evolutionary history, they are not as direct a source of evidence as fossils.

3. **Identifying the Correct Answer**: Among the options, fossils are the most evident source of evolution because they provide concrete evidence of how species have changed over time. They allow for comparisons between ancient and modern organisms, helping to establish evolutionary lineages.

4. **Conclusion**: Therefore, the correct answer to the question is **fossils**.

**Final Answer**: The most evident source of evolution is **fossils**.
