Taxonomic classification is the practice of categorizing and organizing living organisms into hierarchical groups based on their shared characteristics. This system of classification, developed by Swedish biologist Carl Linnaeus in the 18th century, helps scientists to study and understand the diversity of life on Earth. Organisms are grouped into categories such as domain, kingdom, phylum, class, order, family, genus, and species. Taxonomic classification provides a framework for identifying and naming organisms, as well as for studying their evolutionary relationships and biological diversity.
