What is difference between natural classification and artificial classification of living organisms ?

Question

Answer

Difference between Artificial and Natural Systems of Classification

Artificial System:

1. The system is highly useful in the field for quick identification of organisms.

2. Artificial system often utilizes one or two morphological traits.

3. An artificial system may use habit and habitat as criteria for classification.

4. The system does not employ characters from anatomy, cytology, cytochemistry, biochemistry, genetics, ontogeny, etc. for grouping of organisms.

5. Homology is never studied.

6. The system gives no information about natural relationships or phylogeny.

7. It often results in placing of unrelated organisms in a group.

8. Related organisms often get separated into different groups.

Natural System:

1. A natural system often employs artificial keys for quicker identification in the field because the system as such is difficult to operate in the field.

2. The system employs several morphological characters for grouping of organisms.

3. A natural system never uses habit and as criteria for grouping.

4. The system employs all these information’s.

5. It studies homology in all characters including morphology, anatomy, cytotaxonomy, molecular systematics, etc.

6. This system gives information about both natural relationships and phylogeny.

7. There is little chance of placing of unrelated organisms in a group.

8. Related organisms are placed in the same groups.

Answer

Natural classification - the common characters are identified first and then proceeded furthur...while in artificial morphological characters are considered the natural classification was given by Bentham and hooker and artificial classification credit goes to Carolous Linn.

Answer

Natural Classification of Living Organisms

Natural classification refers to the categorization of living organisms based on their natural relationships and evolutionary history. It aims to group organisms together based on their shared characteristics and common ancestry. The key features of natural classification are as follows:

1. Based on Evolutionary Relationships: Natural classification takes into account the evolutionary history of organisms. It categorizes organisms based on their genetic similarities and common ancestry. This approach helps in understanding the evolutionary relationships between different groups of organisms.

2. Hierarchical Structure: Natural classification follows a hierarchical structure where organisms are grouped into broader categories called taxa. The taxa are arranged in a hierarchical manner, from the highest level (Kingdom) to the lowest level (Species), reflecting the evolutionary relationships among organisms.

3. Shared Characteristics: Natural classification focuses on identifying and grouping organisms based on shared characteristics. These characteristics can include morphological features, physiological functions, genetic traits, and ecological roles. The more characteristics organisms share, the closer their evolutionary relationship.

4. Reflects Evolutionary History: Natural classification aims to reflect the evolutionary history of organisms. It groups organisms together based on their shared evolutionary traits and common ancestors. This approach helps in understanding the evolutionary patterns and processes that have shaped the diversity of life on Earth.

Artificial Classification of Living Organisms

Artificial classification, on the other hand, refers to the categorization of living organisms based on arbitrary characteristics that may not reflect their true evolutionary relationships. The key features of artificial classification are as follows:

1. Based on Superficial Characteristics: Artificial classification relies on easily observable traits that may not have any evolutionary significance. These traits can include external appearance, size, color, or habitat preference.

2. Non-Hierarchical Structure: Artificial classification does not follow a hierarchical structure like natural classification. It may group organisms based on a single characteristic without considering their overall relationship or evolutionary history.

3. Subjective and Arbitrary: Artificial classification is subjective and can vary depending on the criteria set by the classifier. It does not necessarily reflect the true evolutionary relationships among organisms.

4. Practical Utility: Artificial classification is often used for practical purposes such as identification, organization, or convenience in scientific studies or everyday life. It may not provide insights into the evolutionary history or relationships of organisms.

Conclusion

In summary, natural classification of living organisms focuses on grouping organisms based on their evolutionary relationships and shared characteristics. It follows a hierarchical structure and aims to reflect the true evolutionary history of organisms. On the other hand, artificial classification relies on superficial traits and does not consider evolutionary relationships. It is subjective and often used for practical purposes. Natural classification provides a more accurate understanding of the diversity of life and helps in studying the evolutionary patterns and processes that have shaped it.
