Natural system of classification differs from artificial system in bringing out similarities and dissimilarities.

The natural system of classification in biology is based on the concept of evolution and seeks to arrange organisms into groups that reflect their evolutionary relationships. On the other hand, the artificial system of classification is based on arbitrary characteristics chosen by humans and does not necessarily reflect evolutionary relationships.

Bringing out similarities and dissimilarities:
1. Natural system of classification:
- The natural system of classification aims to bring out the similarities and dissimilarities between organisms based on their evolutionary history. It considers various characteristics such as morphology, anatomy, physiology, and genetics to determine these relationships.
- It groups organisms based on shared characteristics that are inherited from a common ancestor. This helps in understanding the evolutionary history of different species and their relationships with each other.
- For example, in the natural system of classification, organisms with similar genetic sequences or anatomical structures are grouped together, indicating a closer evolutionary relationship.

2. Artificial system of classification:
- The artificial system of classification, on the other hand, does not consider evolutionary relationships. It is based on a single or a few selected traits that are not necessarily indicative of evolutionary history.
- Artificial classification may focus on easily observable traits like color, size, or number of limbs. These traits may not have any evolutionary significance but are chosen for convenience or practical purposes.
- For example, in an artificial classification system, all red-flowered plants may be grouped together regardless of their evolutionary relationships or other characteristics.

Significance of bringing out similarities and dissimilarities:
1. Evolutionary history:
- The natural system of classification provides valuable insights into the evolutionary history of organisms. By identifying similarities and dissimilarities between species, scientists can reconstruct the evolutionary tree of life and understand the relationships between different groups of organisms.
- This information helps in understanding the origins and diversification of life on Earth.

2. Predicting traits and behaviors:
- Similarities and dissimilarities between organisms can also provide insights into their shared traits and behaviors. Organisms that are closely related are more likely to have similar adaptations and behaviors due to their shared evolutionary history.
- By studying the similarities and dissimilarities between species, scientists can make predictions about the traits and behaviors of different organisms, even if they have not been studied extensively.

3. Conservation and biodiversity:
- Understanding the similarities and dissimilarities between organisms is crucial for conservation efforts and preserving biodiversity.
- By identifying evolutionary relationships, scientists can identify key species and ecosystems that are important for maintaining overall biodiversity. This information can help in prioritizing conservation efforts and protecting vulnerable species.

In conclusion, the natural system of classification differs from the artificial system in its focus on bringing out similarities and dissimilarities based on evolutionary relationships. This approach provides valuable insights into the evolutionary history, traits, and behaviors of organisms and is essential for understanding and conserving biodiversity.
