The science of diversity of organisms is

Options

A. Taxonomy
B. Evolution
C. Systematics
D. Palaeontology

Answer

To solve the question "The science of diversity of organisms is," we will analyze the provided options one by one.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the branch of science that specifically deals with the diversity of organisms.

2. **Analyzing Option A: Taxonomy**:
- Taxonomy is the branch of science that focuses on the classification and naming of organisms. It involves organizing species into categories based on shared characteristics.
- However, taxonomy primarily deals with classification rather than the diversity of organisms as a whole.
- **Conclusion**: Taxonomy is not the correct answer.

3. **Analyzing Option B: Evolution**:
- Evolution is the study of how organisms change over time through heritable traits. It focuses on the processes that lead to the diversity of life forms over generations.
- While evolution explains how diversity arises, it does not specifically focus on the diversity itself.
- **Conclusion**: Evolution is not the correct answer.

4. **Analyzing Option C: Systematics**:
- Systematics is the branch of science that studies the diversity of organisms and their evolutionary relationships. It encompasses both taxonomy and phylogenetics, focusing on understanding how different organisms are related and how they have diversified.
- This option directly addresses the question regarding the diversity of organisms.
- **Conclusion**: Systematics is the correct answer.

5. **Analyzing Option D: Paleontology**:
- Paleontology is the study of fossils and ancient life forms. It provides insights into the history of life on Earth but does not specifically focus on the diversity of living organisms today.
- **Conclusion**: Paleontology is not the correct answer.

### Final Answer:
The correct answer is **Systematics** (Option C).
