Biological classification involves grouping organisms based on shared characteristics and evolutionary relationships. Organisms are organized into a hierarchy of taxonomic ranks including domain, kingdom, phylum, class, order, family, genus, and species. This system allows organisms to be accurately identified and studied based on their evolutionary relationships and physical similarities.
