Is domain more inclusive than a supergroup?

Yes, a domain is generally considered more inclusive than a supergroup in biological classification. In the hierarchy of life, domains (such as Bacteria, Archaea, and Eukarya) encompass the broadest categories of organisms, while supergroups are subdivisions within the domain Eukarya that group together specific lineages based on genetic and evolutionary relationships. Therefore, while all supergroups fall under a domain, a domain includes a wider range of biological diversity.
