Vedclass · Answer

(D) Convergent evolution refers to the development of similar adaptive functional structures in unrelated groups of organisms,which is known as analogy. Examples include the wings of butterflies and birds,the eyes of octopuses and mammals,and the flippers of penguins and dolphins.Divergent evolution involves the development of different functional structures along different directions due to adaptations to different needs from a common ancestral form. $A$ classic example is the forelimbs of vertebrates (e.g.,whales,bats,cheetahs,and humans). Although these limbs perform different functions,they share a similar anatomical structure (homology). Therefore,the correct pair is: Thorns of Bougainvillea and tendrils of Cucurbita (divergent) $\rightarrow$ Eyes of octopus and mammals (convergent).
