“Two areas of study namely ‘evolution’ and ‘classification’ are interlinked”. Justify this statement.

Classification and evolution are linked since the organisms show similarities and dissimilarities from each other. Similarities permit them to put in a group which dissimilarities keep them away apart. We study gram and classify them. Closely related species have more common characters. So they had a common ancestor. Therefore classification seem to be a reflection of their evolutinary relationships. Classification involves hierarchy or keys.
