Knowra Family (biology) Family (biology) A taxonomic rank grouping related genera, positioned between order and genus. Family names are standardized within each nomenclature code, with distinct conventions across major groups of organisms.
Genus : A taxonomic rank grouping closely related species and positioned below family. Families consist of one or more genera.
Felidae : The mammal family that includes cats such as lions, tigers, and domestic cats. Felidae groups several cat genera within one family.
Subfamily : A taxonomic rank below family and above tribe, used when a family is divided into smaller groups. Subfamily provides an optional subdivision within a family.
Phylogenetics : The study of evolutionary relationships among organisms, often represented as branching trees. Phylogenetic evidence can prompt taxonomists to revise family boundaries.
Order (biology) : A taxonomic rank above family and below class in the standard hierarchy. An order contains families, placing family between these two ranks.
Hominidae : The primate family that includes humans, chimpanzees, gorillas, and orangutans. Hominidae demonstrates how multiple related genera can share a family.
Superfamily : A taxonomic rank above family and below order, used to group related families. Superfamily groups families at a broader level than family.
Taxonomic revision : A formal change to the classification or naming of a group of organisms. Revisions can transfer genera between families or redefine a family.
Species : A basic taxonomic rank commonly used for distinct groups of organisms capable of interbreeding. Species are grouped into genera, the immediate rank beneath family.
Canidae : The mammal family that includes dogs, wolves, foxes, and their close relatives. Canidae groups diverse doglike genera at the family rank.
