Of, pertaining to, or relating to taxonomy
Taxonomy refers to a branch of science that deals primarily with the description, identification, nomenclature, and classification of organisms. It aims to classify organisms in a hierarchical system or in taxonomic ranks (e.g. domain, kingdom, phylum or division, class, genus, species) based on shared characteristics or on phylogenetic relationships inferred from the fossil record or established by genetic analysis. For example, organisms are classified into clades (i.e. a taxonomic group of organisms based on homologous features derived from a common ancestor) in phylogenetic taxonomy. The person specializing in this particular field is called a taxonomist. One such notable taxonomist is the Swedish botanist Carl Linnaeus. He is considered as the father of taxonomy. One of his major contributions in taxonomy was a system of classification referred to as Linnaean classification where organisms are categorized into taxa. He was also the proponent of binomial nomenclature.
