Which is a set of evidence of evolution

Options

A. Homologous and analogous organs
B. Homologous and vestigial organs
C. Analogous and vestigial organs
D. All the above.

Answer

To answer the question "Which is a set of evidence of evolution?", we will analyze the provided options and understand the types of organs mentioned.

### Step-by-Step Solution:

1. **Identify the Types of Organs**:
- We have three types of organs mentioned: homologous organs, analogous organs, and vestigial organs.

2. **Understand Homologous Organs**:
- Homologous organs have a similar structure but different origins. For example, the forelimbs of humans and whales are structurally similar but evolved from different ancestors. This similarity in structure despite different functions supports the theory of evolution.

3. **Understand Analogous Organs**:
- Analogous organs have similar functions but different structures and origins. For instance, the wings of birds and insects serve the same function (flying) but have different structural designs and evolutionary origins. This indicates that similar environmental pressures can lead to similar adaptations, which is also evidence of evolution.

4. **Understand Vestigial Organs**:
- Vestigial organs are remnants of organs that were functional in ancestors but are non-functional in the current organism. An example is the human appendix. The presence of these organs suggests a common ancestry and evolutionary change over time.

5. **Evaluate the Options**:
- Option A: Homologous and Analogous organs - Both types provide evidence of evolution.
- Option B: Homologous and Vestigial organs - Both types also provide evidence of evolution.
- Option C: Analogous and Vestigial organs - Both types provide evidence of evolution as well.
- Option D: All of the above - Since all the previous options are correct, this is the most comprehensive answer.

6. **Conclusion**:
- Therefore, the correct answer is **D: All of the above**. Each type of organ mentioned provides evidence supporting the theory of evolution.
