Why do analogous organs not give strong evidence of common ancestry even if they perform similar functions?
Answer and explanation
Correct answer: Because their basic structures and evolutionary origins are different
Analogous organs perform similar functions but arise from different basic structures and evolutionary histories. For example, wings of birds and insects both support flight, yet a bird wing is a modified bony forelimb while an insect wing develops from a different body structure. Similar environmental demands can produce similar functions without close ancestry. Thus option A is correct; the other choices are biologically false or irrelevant.
