Reference: AQA
Linnaeus arranged living things into a hierarchy of seven groups: kingdom, phylum, class, order, family, genus and species, where each level contains fewer organisms with more shared features.
A system in which each group is nested inside the one above, so a species belongs to a genus, which belongs to a family, and so on.
