| D. Darwin finches | IV. Mutation |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → A-III, B-I, C-IV, D-II
(A) Tendrils of Cucurbita and thorns of Bougainvillea — this matches (III) Divergent evolution. Both are modified stems (homologous organs): the same basic structure has been changed for different jobs.
(B) Sweet potato and potato — this matches (I) Convergent evolution. Sweet potato is a root and potato a stem; different structures do the same job of storing food (analogous organs).
(C) Evening prime rose — this matches (IV) Mutation. Hugo de Vries saw new forms suddenly appear in the evening primrose and called these large changes mutations.
(D) Darwin finches — this matches (II) Adaptive radiation. From one seed-eating ancestor, finches with different beaks evolved on the Galapagos Islands for different foods.
