Biological clessification, or scienteefic clessification in biology, is a method o scienteefic taxonomy uised tae group an categorize organisms intae groups such as genus or species. These groops are kent as taxa (singular: taxon).
Modren biological clessification hars its ruit in the wirk o Carolus Linnaeus, who grooped species accordin tae shared pheesical characteristics. These groopins hae syne been revised tae improve consistency wi the Darwinian principle o common strynd. Wi the introduction o the cladistic method in the late 20t century, phylogenetic taxonomy in which organisms are grooped based purely on inferred evolutionary relatitness, ignorin morphological similarity, haes acome common in some auries o biology. Molecular phylogenetics, which uises DNA sequences as data, haes an aa driven mony recent reveesions an is likely tae continue daein so. Biological clessification belangs tae the science o biological seestematics.
