Classification system are chaning every now and then because an attempt has been made to evolve such a sytem ultimately which is able to explain evolutionary relations in organisms. What was the correct sequence of these types of classification systems with respect to their solutions:-

Options

A. Practical `to` Artificial `to ` Natural `to `Phylogenetic ` to `Numerical
B. Artificial `to` Practical `to `Numerical `to` phylogenetic
C. Practical `to` Artificial `to` Natural `to ` Numerical `to` Phylogenetic
D. Numerical `to` Artificial `to`Natural `to` Practical `to` phylogenetic

Answer

To answer the question regarding the correct sequence of classification systems that explain evolutionary relationships in organisms, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Identify the First Classification System:**
- The first classification system was proposed by Aristotle around 350 BC. This system is known as the **Artificial System of Classification**. It primarily used one or two morphological characteristics to group organisms.

2. **Second Classification System:**
- Following the artificial system, the next significant development was the **Practical System of Classification**. This system aimed to categorize organisms based on practical and observable traits.

3. **Third Classification System:**
- The third system is the **Numerical System of Classification**. This system evaluates organisms based on their resemblances and differences using statistical methods. It considers a large number of characters to assess whether organisms are primitive or advanced.

4. **Fourth Classification System:**
- The final and most advanced system is the **Phylogenetic System of Classification**. This system focuses on the evolutionary relationships among organisms, determining classifications based on common ancestors and evolutionary lineage.

5. **Correct Sequence:**
- Therefore, the correct sequence of these classification systems is:
1. Artificial System of Classification (Aristotle)
2. Practical System of Classification
3. Numerical System of Classification
4. Phylogenetic System of Classification

### Final Answer:
The correct sequence of classification systems with respect to their evolutionary relations is:
1. Artificial System of Classification
2. Practical System of Classification
3. Numerical System of Classification
4. Phylogenetic System of Classification
