Phylum Class Order Family Genus Species |
In the Linnaean system (and taxonomic systems based on it), the Family is a taxonomic category between Order and Tribe. It might seem strange that a family is considered higher than a tribe (i.e. a family can contain many tribes, but not vice versa), but such is the way these names are. When there are no Tribes, the Family is a taxonomic category between Order and Genus. More even then an order, a family is a group of organisms among which the differences are quite minor, e.g. Equidae - horses and their relatives, Ceratopsidae - horned dinosaurs, or Hominidae, man and ape-men (although again the differences among Hominids are extremely slight, here we see a chauvinistic taxonomic inflation, elevated a probably genus rank to family ranking). Some families contain thousands of species, others might only have a single species. |
