Question:
What are the advantages of classification?
Answer:
Following are the advantages of classification:
- Classification helps us identify the living organisms easily.
- It makes a study of such a wide variety of bio-life in a systematic manner.
- It helps us learning different plants and animals, similarities and dissimilarities among them.
- Enables us understand how complex organisms evolve over the time.
- Classification helps us understand the inter-relationships among different groups.
- It forms the basis of other branches of bio-sciences like bio-geography, environmental biology, ecology etc.
- It also provides a systematic way to identify known and unknown organisms.
- Classification systems are adapted internationally. This aids communication between scientists.
