Which system of classification prioritizes evolutionary and genetic relationships of organisms?

Answer and explanation

Correct answer: Phylogenetic system

A phylogenetic classification groups organisms according to their evolutionary history and inferred relationships. It uses evidence such as shared ancestry, structural features, and genetic or molecular similarities. Organisms placed close together in such a system are expected to share a more recent common ancestor than organisms placed far apart. This approach tries to represent the branching pattern of life rather than relying only on visible convenience.

Option B, the phylogenetic system, is correct. An artificial system selects a few easily observed traits and may group unrelated organisms together. A natural system considers several similarities and gives a broader picture, but the question specifically emphasizes evolutionary and genetic relationships. “Sexual system” is not the relevant biological classification system here. Thus the supplied choice correctly names the system centered on descent and evolutionary relationships.
