why do we classify organisms

Classification refers to the identification, naming, and grouping of organisms into a formal system based on similarities in their internal and external structure or evolutionary history. It determines the methods of organizing diversity of life on earth. Therefore, classification helps in understanding millions of life forms in detail. Classification allows things to be identified and categorized on the basis of structure and function of an organism, and accordingly, we can refer to them as primitive or advanced organisms. This helps in predicting the line of evolution.
