Q6 of 40 Page 1

Select two pairs from the following which exhibit divergent evolution. Give reasons for your answer.

(i) Forelimbs of cheetah and mammals


(ii) Flippers of dolphins and penguins


(iii) Wings of butterflies and birds


(iv) Forelimbs of whales and mammals


The combination having divergent evolution are:

(i) Forelimbs of cheetah and mammals


(ii) Forelimbs of whales and mammals


These two pairs exhibit divergent evolution because they have similar anatomical structure but they perform different functions.Hence, the same structural organs in these animals have developed in different ways because of adaptations to their different requirements. This shows that the divergent evolution and that the structures or organs are Homologous.
