Every species or organisms has inbuilt tendency for genetic variation which plays an important role in the origin of new species and forms the basis for evolution. Organisms appear to be same because of similarity in their inherited body designs. The more characteristics two species have in common, the more closely they are related. And they are likely to have a a common ancestor more recently. Classification of organisms necessarily involves, organizing them in different groups, based on the similarities and differences of characteristics. Classifying organisms helps us in recognizing the basic arrangement of a hierarchical structure among diverse species. It tells us about the resemblances and relationships between various organisms thus facilitating studies or research of wide variety associated with organisms effortlessly.
Different life forms have evolved during the course of evolution.
Classification deals with the grouping of these life forms into groups and sub groups based on similarities and differences.
The more characteristics any two species have in common, more closely they are related.
In fact, classification of species is a reflection of their evolutionary relationship. Thus, we can say, the areas of study evolution and classification interlinked.
