The modern six kingdom classification was developed by microbiologist and botanist Robert Whittaker in the late 1950s and early 1960s. This classification system was created to provide a more precise, inclusive, and detailed understanding of taxonomy (the science of classifying living things). Whittaker’s classification system was based on several different factors, including the organism’s mode of nutrition, cell structure, and genetic makeup. He divided living organisms into five kingdoms: Animalia, Plantae, Fungi, Protista, and Monera. In 1977, Carl Woese further divided the kingdom Monera into two separate kingdoms, Eubacteria and Archaebacteria. This resulted in the six kingdom classification system that is still used today.
