What are the difficulties that you would face in the classification of animals if common fundamental features are not taken into account?

(N/A) The classification of living organisms relies on identifying common fundamental characteristics to group them systematically.
If common fundamental features are ignored and only specific or unique characteristics are considered,every organism would likely be placed in a separate group,making the classification system impractical and overly complex.
The primary objective of classification is to simplify the study of diverse life forms and understand their evolutionary relationships.
By focusing on shared traits such as the level of organization,symmetry,diploblastic or triploblastic nature,coelom,and segmentation,we can establish a hierarchy that reflects biological relationships.
Without these common features,it would be impossible to compare different organisms or determine their evolutionary significance,thereby defeating the entire purpose of biological classification.
