The three-domain system was created to provide a more accurate representation of the evolutionary relationships among organisms. Prior to its introduction, the five-kingdom system grouped all prokaryotes under the kingdom Monera, which was later found to be polyphyletic. The three-domain system, introduced by Carl Woese in 1990, recognizes the fundamental differences between Archaea and Bacteria, leading to a more accurate classification of life forms.
