Question:How are the areas of study - evolution and classification - interlinked?
Answer:the classification of organisms is a reflection of their evolutionary relationships. Classification is based on similarities and differences amongst organisms:
the more characteristics 2 organisms have in common, the more closely they are related and the more recently they will have had a common ancestor in the evolutionary chain,
the more different characteristics 2 organisms have, the more remotely they are related and they will have had a common ancestor in the more remote past
