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.
