(A/N FROM HERE WE WILL START BIOLOGICAL CLASSIFICATION.)

Different types of classification 

*ARTIFICIAL SYSTEM OF CLASSIFICATION ----> Classification is done on basis of very superficial basis of characters. e.g movable characters, bacteria and humans both. 

*NATURAL SYSTEM OF CLASSIFICATION ----> Classification is done on the basis of multiple  basis, descent from a common ancestor.
