Q. Which one of the following options gives one correct example each of convergent evolution and divergent evolution?
A) Convergent: Thorns of Bougainvillea and tendrils of Cucurbita; Divergent: Eyes of octopus and mammals
B) Convergent: Eyes of octopus and mammals; Divergent: Bones of forelimbs of vertebrates
C) Convergent: Thorns of Bougainvillea and tendrils of Cucurbita; Divergent: Wings of butterflies and birds
D) Convergent: Bones of forelimbs of vertebrates; Divergent: Wings of butterfly and birds
Explanation
[Solution from source] Eyes of octopus and mammals are analogous structures that evolved independently (convergent evolution), while the forelimb bones of vertebrates are homologous structures from a common ancestor (divergent evolution). Thorns of Bougainvillea and tendrils of Cucurbita are homologous, not convergent, and wings of butterflies and birds are analogous, not divergent. Answer (2).
