Detailed explanation-1: -Reasons: New organisms are constantly being discovered and for classifying them, the new system needs to be used. This is why the new classification system is constantly developed to classify the organisms based on the similarity in characters.
Detailed explanation-2: -Over time, the Linnean classification system was expanded, first to three kingdoms and then to four. By the 1960s, scientists had organized living things into five kingdoms-the Monera (bacteria), Protista (protozoa and algae), Fungi (mushrooms, yeasts, and molds), Plantae (plants), and Animalia (animals).
Detailed explanation-3: -The classification system provides great deal of information about the characteristics of organisms. Using scientific names can therefore act as a shorthand method for describing a plant or animal.
Detailed explanation-4: -For example, scientists can use DNA sequences to help determine if they have discovered a new species. Scientists can also compare DNA sequences from different organisms and measure the number of changes (mutations) between them to infer if species are closely or distantly related.
