Which is a correct example of homologous organs?
Answer and explanation
Correct answer: Human arm and whale forelimb
Homologous organs have a similar basic structural plan and common evolutionary origin, although their present functions may differ. The bones in a human arm and a whale forelimb follow the same basic arrangement, even though they are used differently. Hence option A is correct. Bird and insect wings are analogous, while the other pairs do not represent the standard homologous comparison.
