Systematic biology (hereafter called simply systematics) is the field that (a) provides scientific names for organisms, (b) describes them, (c) preserves collections of them, (d) provides classifications for the organisms, keys for their identification, and data on their distributions, (e) investigates their evolutionary histories, and (f ...
The 1735 classification of animals Linnaeus's work had a huge impact on science; it was indispensable as a foundation for biological nomenclature , now regulated by the Nomenclature Codes . Two of his works, the first edition of the Species Plantarum (1753) for plants and the 10th edition of the Systema Naturæ (1758), are accepted to be among ...
Taxonomic rank is a classification level in biological taxonomy, such as species, genus, family, order, class, phylum, and kingdom.
The hierarchy of biological classification's eight major taxonomic ranks. A phylum contains one or more classes. Intermediate minor rankings are not shown. In biological classification, class (Latin: classis) is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. It is a group of related taxonomic orders.
The particular form of biological classification (taxonomy) set up by Carl Linnaeus, as set forth in his Systema Naturae (1735) and subsequent works. In the taxonomy of Linnaeus there are three kingdoms, divided into classes, and the classes divided into lower ranks in a hierarchical order. A term for rank-based classification of organisms, in ...
The hierarchy of biological classification's eight major taxonomic ranks. A domain contains one or more kingdoms. Intermediate minor rankings are not shown. In biology, a kingdom is the second highest taxonomic rank, just below domain. Kingdoms are divided into smaller groups called phyla (singular phylum).

Later classifications added to the number of species described, but continued to give species status to relatively minor variants, such as winter-vs. spring-forms. The wild wheats were not described until the mid-19th century because of the poor state of botanical exploration in the Near East , where they grow.
