The Living World
Why are the classification systems changing every now and then?
Millions of plants, animals, and microorganisms are found on earth, many of which are still unclassified. Scientists keep on discovering new species around the world. Some of these cannot be placed in the traditional classification system. Therefore, to classify these newly discovered species, with new characters, new systems of classification have to be devised every now and then.
