The introduction of the new kingdom Protista in addition to Plantae and Animalia, led to uncertainty as to whether fungi truly were best placed in the Plantae or whether they ought to be reclassified as protists.

Ernst Haeckel, in his 1866 " Generelle Morphologie der Organismen ", asserted that all living things were monophyletic ( had a single evolutionary origin ), being divided into plants, protista, and animals.
33.
No fungi or protista have the classification, though only four species in those kingdoms have been evaluated by the IUCN . Humans qualify for this category, and in 2008 were formally assessed as such by the IUCN.

""'Geinitzina " "'is a genus of Foraminifera ( Protista or Protozoa ) from the early Carboniferous ( late Mississippian to the late Permian that may have extended into the Triassic.
35.
As new discoveries enabled detailed study of Haeckel in the kingdom Protista; later, the prokaryotes were split off in the kingdom Monera, which would eventually be divided into two separate groups, the Bacteria and the Archaea.

I don't know enough about protista and bacteria, but I can guess they probably can get rather messy as well . "'talk "'02 : 13, 15 October 2007 ( UTC)

It was the question of where to put such " unclassifiable " creatures that prompted Ernst Haeckel to add a third kingdom to the " Animale " and " Vegetabile " of Linnaeus : the Kingdom Protista.
38.
The main categories are : Category : Bacteria and : Category : Protista, and to avoid being overloaded should only include articles on top-level subgroups, or groups that have been considered top-level in the past.
39.
At first, Haeckel included a few multicellular organisms in this kingdom, but in later work he restricted the Protista to single-celled organisms, or simple colonies whose individual cells are not differentiated into different kinds of tissues.
40.
Since then, various life forms have been moved into three new kingdoms : Monera, for prokaryotes ( i . e ., bacteria ); Protista, for protozoans and most algae; and Eukaryota, comprising the remaining forms.
