The eukaryotes are often treated as a superkingdom, or domain.

Eukaryotes evolved in the Proterozoic eon. The oldest known probable eukaryote is Grypania, a coiled, unbranched filament up to 30mm long.[3] The oldest Grypania fossils come from an iron mine near Negaunee, Michigan. The fossils were originally dated as 2100 million years ago,[4] but later research showed the date as about 1874 million years ago.[5] Grypania lasted into the Mesoproterozoic era.

Another ancient group is the acritarchs, believed to be the cysts or reproductive stages of algal plankton. They are found 1400 million years ago, in the Mesoproterozoic era.[6]p57

The classification of the Eukaryota is under active discussion, and several taxonomies have been proposed. All modern versions have five kingdoms, but disagree about which groups go into each kingdom.
