Who introduced the five-kingdom system of classification?

Explanation

The five-kingdom classification system was developed by Robert Whittaker, distinguishing organisms into Monera, Protista, Fungi, Plantae, and Animalia. Carl Linnaeus created the binomial nomenclature, Édouard Chatton proposed the prokaryote-eukaryote distinction, and Lynn Margulis and Karlene Schwartz contributed to endosymbiotic theory.
