What caution do analogous organs teach us in the study of evolution?
Answer and explanation
Correct answer: Similar function does not always prove the same basic structure or common ancestry
Analogous organs perform similar functions but arise from different basic structural plans and do not necessarily indicate close common ancestry. Bird wings and insect wings both enable flight, yet one is a bony vertebrate forelimb and the other is an external insect structure. Therefore option A is correct. Similar function alone is insufficient evidence; B, C, and D are false.
