Final answer:
The purpose of a taxonomic system is to allow for a scientific classification throughout the world.
Step-by-step explanation:
Taxonomy, sometimes referred to as the Linnaean system, is the science of naming and grouping species to construct an internationally shared classification system.
This system uses a hierarchical model which includes a series of nested groups, akin to directories on a computer, or the organization of a grocery store from departments down to individual products. This hierarchical structure begins with three large categories known as domains: Bacteria, Archaea, and Eukarya, and continues with increasingly specific categories: kingdom, phylum, class, order, family, genus, and species.
Scientists in the field of systematics provide crucial information on how organisms are similar or different, and this contributes to building, updating, and maintaining the "tree of life". As new species and character information are discovered by scientists, these taxonomic trees evolve to reflect more accurate data and to provide a consistent framework for classification across the world.
