Taxon
Taxon
Taxon (pronounced: /ˈtæks.ɑːn/) is a term used in biology and taxonomy to refer to a group of one or more populations of an organism or organisms, which a taxonomist adjudges to form a unit. The term was coined by the German botanist Julius von Sachs in 1875, derived from the Greek τάξις (taxis), meaning 'arrangement' or 'order'.
Etymology
The term "taxon" was first introduced in 1926 by the International Congress of Botany in Cambridge, England. It was derived from the Greek word "τάξις" (taxis), which means 'arrangement' or 'order'. The term was later adopted by the International Code of Zoological Nomenclature in 1961.
