Question

How are the areas of study evolution and classification interlinked?

Answer 1

Different forms of organisms have evolved during the course of evolution. Classification deals with grouping of these organisms into groups and subgroups based on their similarities and differences. The more characteristics any two species have in common more closely they are related. In other words, they will have a more recent ancestor.
Thus, classification helps tracing the evolutionary relationships between the two organisms. Hence classification and evolution are interlinked

Answer 2

How are areas of study evolution & classification interlinked?

The two species having most common characteristic are considered to be closely related and have originated from common ancestor.

The modern classification is based on the phylogenetic resemblance between the spaces.

Systematics is the branch of taxonomy which deals with the classification of living beings on the basis of evolution
