What is the classification based on evolutionary relationships among organisms called?

Correct answer: Phylogenetic classification

Correct answer: A, phylogenetic classification. Phylogeny means the evolutionary history and relationships of organisms. A phylogenetic system groups organisms by their inferred common ancestry and evolutionary relationships, using evidence such as structural, developmental and molecular features. A is correct because it directly describes classification based on evolutionary history. B is incorrect because artificial classification uses a few convenient or superficial characters and does not primarily represent evolutionary relationships. C is incorrect because morphological classification focuses on form and structure; morphology may provide evidence, but the term does not necessarily mean a complete evolutionary classification. D is incorrect because “domestic classification” is not the accepted scientific term for this basis of classification. Memory cue: phylogeny means “family history through evolution.”
