There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, and species.

It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of ...

The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family".
The principal ranks in modern use are domain, kingdom, phylum (division is sometimes used in botany in place of phylum), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms.
This, in turn, may be altering family (and birth order) dynamics—and not in a bad way. First, a quick look at the data: Between 1967 and 2017, the spacing between sibling births only increased ...
The difference in nomenclature between the various kingdoms/domains is reviewed in.
