Biological Classification – Quick Revision

Classification is the scientific procedure of arrangement of living organism into groups. It is done on the basis of their similarities and dissimilarities and placing the groups in a hierarchy of categories.

The first pioneer work on biological classification was done by Linnaeus. He classified living organisms into the two kingdoms, i.e Plantae and Animalia. But this classification system proved to be inadequate as there were many organisms that did not fall into any of the categories. Afterwards, the classification system for living organisms has undergone several changes. However, the place of plant and animal kingdoms remains consistent under all different systems
