A system of classification that is based on evolution , order and ancestry is known as

Options

A. Natural system
B. Analogous system
C. Phylogenetic system
D. Homologous system

Answer

To solve the question "A system of classification that is based on evolution, order and ancestry is known as," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a classification system that relies on evolutionary relationships and ancestry among organisms.

2. **Identify the Options**: The options provided are:
- Natural system
- Analogous system
- Phylogenetic system
- Homologous system

3. **Define Each Option**:
- **Natural System**: This system is based on morphological and anatomical characteristics of organisms.
- **Analogous System**: This refers to similarities between organisms that arise from convergent evolution, not from a common ancestor.
- **Phylogenetic System**: This classification is based on the evolutionary history and relationships among organisms, considering their ancestry.
- **Homologous System**: This refers to traits that are similar due to shared ancestry, but it is not a classification system by itself.

4. **Analyze the Correct Answer**: Since the question specifically mentions a system based on evolution, order, and ancestry, the **Phylogenetic System** is the most appropriate choice. It focuses on the evolutionary histories and relationships of organisms.

5. **Conclusion**: Therefore, the answer to the question is the **Phylogenetic System**.

### Final Answer:
The system of classification that is based on evolution, order, and ancestry is known as the **Phylogenetic System**.
