Best Answer: Taxonomy is the science of classifying organisms. The system currently used by taxonomists is called the Linnaean taxonomic system, in honor of Swedish biologist Carolus Linnaeus (1707 â 1778). The Linnaean system breaks down organisms into seven major divisions, called taxa (singular: taxon).
The second feature of Linnaeus's taxonomy system that simplifies organism classification is the ordering of species into broad categories. The major categories include: Kingdom, Phylum, Class, Order, Family, Genus, and Species.These categories have been updated to include Domain in the taxonomic hierarchy.Domain is the broadest category and organisms are grouped primarily according to differences in ribosomal RNA structure.innaeus's taxonomy system has two main features that contribute to its ease of use in naming and grouping organisms. The first is the use of binomial nomenclature. This means that an organism's scientific name is comprised of a combination of two terms. These terms are the genus name and the species or epithet.
