International Code of Phylogenetic Nomenclature

The International Code of Phylogenetic Nomenclature (ICPN) provides standardized rules for naming groups of organisms based on their evolutionary history and relationships. Unlike traditional naming methods, it emphasizes the use of precise, objective criteria—like common ancestors and branching patterns—to define each group. This approach aims for stability and clarity, ensuring that names reflect actual evolutionary connections. By doing so, the ICPN helps scientists communicate consistently about the diversity of life, regardless of changes in new discoveries or classifications, making taxonomy more accurate and scientifically rigorous.
