    Early classification

    Early systems grouped organisms into broad categories, like kingdoms, often based on limited knowledge.

    Kingdoms and Domains

    Levels of biological classification; kingdoms are broader than domains and domains are more specific.

    Monera Kingdom

    A historical kingdom of unicellular, prokaryotic organisms (no nucleus).

    Eubacteria

    A group of prokaryotes, one of the types in the Monera kingdom.
