What purpose does the International Code of Zoological Nomenclature (ICZN) serve?

The International Code of Zoological Nomenclature (ICZN) serves the purpose of providing standardized guidelines for naming animal species. This is crucial for ensuring consistency and clarity in the scientific naming of animals across the globe, facilitating communication among scientists and researchers. By establishing rules for the naming conventions, such as how to form valid names and the criteria for their use, the ICZN helps avoid confusion that can arise from synonyms or outdated names within the scientific community. This framework is essential for taxonomic work and biodiversity studies, as it enables accurate identification and classification of species, which is foundational in areas like ecology, conservation, and evolutionary biology.

Other options, while related to biology and ecology, focus on different aspects: habitat regulation, evolutionary analysis, and pollution control are important fields but do not pertain to the nomenclatural standards that the ICZN specifically addresses.
