Question

Which one of the following options gives one correct example of convergent evolution and divergent evolution respectively?

A

Convergent: Eyes of octopus and mammals; Divergent: Bones of forelimbs of vertebrates

B

Convergent: Thorns of Bougainvillea and tendrils Cucurbita; Divergent: Wings of butterflies and birds

C

Convergent: Bones of forelimbs of vertebrates; Divergent: Wings of butterfly and birds

D

Convergent: Thorns of Bougainvillea and tendrils of Cucurbita; Divergent: Eyes of Octopus and mammals

Step-by-Step Solution

the eyes of the octopus and of mammals are analogous structures resulting from convergent evolution, where different structures evolve for the same function , . Conversely, the bones of forelimbs of vertebrates (like whales, bats, cheetahs, and humans) are homologous structures that indicate common ancestry and are a result of divergent evolution , . The thorns of Bougainvillea and tendrils of Cucurbita are examples of divergent evolution (homology) , while the wings of butterflies and birds are examples of convergent evolution (analogy) .

Exam Context & Concepts Covered
