Question:
Our current biology text lists five kingdoms:monera, protista, fungi,plantae, and animalia. Does the present classification system use these five, or have there been recent changes?


Replies:
Currently the five kingdom classifications stands. Monera, protista, plantae, fungi and animalia. However, there is movement under foot to change to an eight kingdom system [Monera into two, and Protista into three] or a three kingdom system [the three cell types, archaea, prokarotic and eukaryotic.

David,

Most high school biology texts still show 5 kingdoms and teachers are therefore largely encouraged to teach that system, though some AP texts have begun to modernize their representation of the classification of organisms. Biologists, however, generally agree that that 5-kingdom system had serious flaws and current data from molecular biology/genetics show that there are instead three primary lineages from the original common ancester: archaea, eubacteria/bacteria and eukarya. More information can be obtained by a web search using those now-common group names.
