Question: How much kingdoms are there? I know there is Anamalia and Fungi, but I pretty sure there are 4 or 5 kingdoms

  1. Hi Pnemono

    Under the Cavalier-Smith 2004 classification there are 6 kingdoms: bacteria, protozoa, chromista, plantae, fungi, and animalia.

    But the classifications, especially in the multi-celled organisms, do not really mean much due to phylogenetic classification.

  3. Hi pnemo,
    Dustin has answered this well. I just want to add something to show you how quickly the classification system can change. The 6 kingdom names Dustin has told you are from a revision of the classification in 2004. I started uni in 2003, and at the time the names of the 6 kingdoms we were taught were Animalia, Plantae, Fungi, Protista, Archaea, and Bacteria. When I was at in Year 11 and 12 at school (2001-2002), we were taught in biology class about a 5 kingdom model (Animalia, Plantae, Fungi, Prokarya, Monera).
    The phylogenetic classification system is a pretty fluid thing and is constantly changing as scientists discover more similarities and differences between forms of life, as well as more forms of life sometimes, and group organisms differently or change the names of different groups.
