Why are both similarity and variation important from the viewpoint of evolution?
Answer and explanation
Correct answer: Similarity indicates common ancestry and variation provides material for change
Similarity among organisms, especially in basic structures or inherited features, can indicate descent from a common ancestor. Variation creates differences within a population, and natural selection may favour some of those differences under changing conditions. Thus option A correctly combines evidence of ancestry with the raw material for evolutionary change. The other statements contradict heredity and selection.
