Which one of the following options gives one correct example each of convergent evolution and divergent evolution?
A
Convergent evolution: Thorns of Bougainvillea and tendrils of Cucurbita;
Divergent evolution: Eyes of Octopus and mammals
Divergent evolution: Eyes of Octopus and mammals
B
Convergent evolution: Eyes of octopus and mammals;
Divergent evolution: Bones of forelimbs of vertebrates
Divergent evolution: Bones of forelimbs of vertebrates
C
Convergent evolution: Thorns of Bougainvillea and tendrils of Cucurbita;
Divergent evolution: Wings of butterflies and birds
Divergent evolution: Wings of butterflies and birds
D
Convergent evolution: Bones of forelimbs of vertebrates;
Divergent evolution: Wings of butterfly and birds
Divergent evolution: Wings of butterfly and birds
Detailed Solution
Convergent evolution gives analogous structures: different origin, similar function. Eyes of octopus and mammals are an example (so are wings of butterflies and birds).
Divergent evolution gives homologous structures: same origin, different functions. Bones of the forelimbs of vertebrates are an example (so are thorns of Bougainvillea and tendrils of Cucurbita).
So the correct pairing is eyes of octopus and mammals (convergent) and bones of forelimbs of vertebrates (divergent).
