What is Full Form of ICZN
The full form of ICZN is International Code of Zoological Nomenclature. It is a set of rules and recommendations for the formal scientific naming of animals to ensure consistency and universality in zoological taxonomy.
Evolution and Development of ICZN
The International Code of Zoological Nomenclature (ICZN) traces its origins to the late 19th century when the need for standardized animal naming conventions became evident. The first formal rules were established by the International Commission on Zoological Nomenclature, founded in 1895.
The Code underwent multiple revisions to adapt to scientific advancements, with major editions published in 1905, 1961, 1985, and 1999. Over time, it has evolved to ensure stability and clarity in zoological names, incorporating digital taxonomy and addressing issues like electronic publication. Today, the ICZN remains the guiding framework for naming animal species worldwide.
ICZN Functions:
ICZN ensures a universal system for naming animals, preventing confusion in scientific communication.
It establishes rules for naming priority, ensuring older valid names take precedence to maintain stability.
The Code provides guidelines for handling name changes, synonyms, and classification conflicts in zoological taxonomy.
ICZN allows electronically published names under specific conditions, adapting to modern scientific practices.
Principles of the International Code of Zoological Nomenclature
The principle of priority ensures the earliest valid name is recognized for a species.
The principle of binomial nomenclature mandates a two-part scientific name for each species.
The principle of coordination ensures consistency in naming across taxonomic ranks.
The principle of homonymy prevents the use of identical names for different taxa.
Role and Significance of the International Commission on Zoological Nomenclature
The International Commission on Zoological Nomenclature (ICZN) plays a crucial role in maintaining consistency and stability in the scientific naming of animals. It ensures that species names follow standardized rules under the International Code of Zoological Nomenclature (ICZN Code), preventing confusion in taxonomy.
The commission resolves naming disputes, enforces the principle of priority, and provides official rulings on controversial cases. Additionally, it adapts the Code to accommodate modern scientific advancements, including digital publications, ensuring the continued accuracy and relevance of zoological nomenclature worldwide.
Conclusion:
The International Code of Zoological Nomenclature (ICZN) is essential for maintaining consistency, stability, and universality in the scientific naming of animals. By establishing clear rules and principles, it prevents confusion in taxonomy and ensures that names are applied systematically.
The International Commission on Zoological Nomenclature (ICZN) continues to oversee and adapt the Code, addressing challenges in modern taxonomy, including digital publications. Its role remains vital in supporting scientific communication and preserving the integrity of zoological nomenclature worldwide.

FAQs on ICZN Full Form
1. What do ICBN and ICZN stand for?
ICBN stands for International Code of Botanical Nomenclature, and ICZN stands for International Code of Zoological Nomenclature. They regulate the scientific naming of plants and animals, respectively.
2. What is the function of the ICZN?
The ICZN ensures a standardized system for naming animals, maintaining stability, priority, and uniformity in zoological nomenclature while preventing confusion in classification.
3. What is ICZN and IVF?
ICZN is the system of rules governing the scientific naming of animals, whereas IVF (In Vitro Fertilization) is a medical procedure that helps with reproduction by fertilizing an egg outside the body.
4. Who is the father of ICBN?
Adolf Engler is regarded as the father of the International Code of Botanical Nomenclature (ICBN).
5. What are the five codes of nomenclature?
The five major codes of biological nomenclature are:
ICZN – International Code of Zoological Nomenclature (for animals)
ICBN / ICN – International Code of Nomenclature for algae, fungi, and plants (formerly ICBN)
ICNP – International Code of Nomenclature of Prokaryotes (for bacteria)
ICVCN – International Code of Virus Classification and Nomenclature (for viruses)
ICNCP – International Code of Nomenclature for Cultivated Plants
6. What is the objective of ICZN?
The main objective of ICZN is to provide globally accepted rules for naming animals, ensuring consistency, stability, and preventing duplication or confusion in taxonomy.
7. What are the three parts of the ICZN?
The three key parts of the ICZN include:
Principles – Fundamental rules guiding zoological naming.
Rules and Recommendations – Specific guidelines for classification and naming.
Appendices – Additional materials, including official rulings and modifications.
