Evolutionary history of an organism is called

Options

A. Taxon
B. Phylogeny
C. Taxonomic hierarchy
D. Metabolism

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes the evolutionary history of an organism.

2. **Analyzing the Options**: We have four options to consider:
- Texon
- Phylogeny
- Taxonomic hierarchy
- Metabolism

3. **Defining Each Term**:
- **Texon**: This term refers to a unit of taxonomic hierarchy, which includes categories like kingdom, phylum, class, order, family, genus, and species. It does not refer to evolutionary history.
- **Phylogeny**: This term specifically refers to the evolutionary history of a species or group of related species. It provides insights into how different organisms are related through evolution.
- **Taxonomic Hierarchy**: This is a system of organizing biological classification into ranks or categories. It does not directly refer to evolutionary history but rather to the structure of classification.
- **Metabolism**: This term refers to all the biochemical reactions occurring within an organism. It is unrelated to evolutionary history.

4. **Identifying the Correct Answer**: Based on the definitions:
- Texon is not the answer as it relates to classification.
- Phylogeny is the correct answer, as it directly refers to the evolutionary history of an organism.
- Taxonomic hierarchy and metabolism do not pertain to evolutionary history.

5. **Conclusion**: The correct answer to the question is **Phylogeny**.
