What is the term for the subdivision of an order made up of related species?

The term referring to a subdivision of an order that consists of related species is "Families." In biological classification, the hierarchy goes from broader categories to more specific ones. An order consists of multiple families, each comprising species that share certain characteristics and evolutionary links. Families serve as a way to group related genera, which in turn consist of species. This system helps in understanding the relationships and traits shared among different species within the same family, highlighting their common ancestry and behavioral, morphological, or ecological similarities.
