Describes the Linnean taxonomy, a way of classifying organisms in a hierarchy based on similarities and physical traits, as well as binomial nomenclature.
The three most commonly used methods are phenetics, cladistics, and evolutionary taxonomy. Some taxonomists use a combination of several of these different methods. Groups of organisms in taxonomy are called taxa (singular, taxon). You may already be familiar with commonly used taxa, such as the kingdom and species. A kingdom is a major grouping of organisms, such as plants or animals.
