Answer:
The Linnaean system of classification is also known as the classical system of biological classification proposed by the Carolus Linnaeus. He categorised the organisms into two groups- the plants and animals on the basis of morphological characters.
But this system has evolved with time from two kingdoms to six kingdom system which is divided into Archaebacteria, Eubacteria, Protista, Fungi Animalia and Plantae with time due to the advancements in technology and understanding of nature into depth.
This shows that knowledge can be modified with time depending on the understanding of nature.
