    • Recent genetic analysis and other advancements have found that some earlier classifications do not align with the evolutionary past; therefore, changes and updates are made as new discoveries occur.

      Classification systems have continued to be developed by other scientists, such as Carl Woese who developed the three-domain system. This is based on evidence now available from chemical analysis.

      The updated system divides organisms into:

      Archaea (primitive bacteria usually living in extreme environments)

      Bacteria (true bacteria)

      Eukaryota (including protists, fungi, plants, and animals)
