Which of the following options gives one correct example for each of convergent evolution and divergent evolution

	Covergent evolution	Divergent evolution
1	Brains in vertebrates	Flippers of penguins and dolphins
2	Bones of forelimbs of vertebrates	Wings of butterfly and birds
3	Sweet potato and potato	Bones of forelimbs of vertebrates
4	Flippers of penguins and dolphins	Eyes of octopus and mammals

Sweet potato and potato perform the same function i.e store starch,  sweet potato is a stem modification and potato is a root modification. Same function but structurally different therefore convergent evolution. Bones of the forelimbs of vertebrates are structurally similar but functionally different as the forelimbs of man, cheetah, whale and bat are structurally similar, but the forelimbs of man help in gripping, in cheetah help in fast running, and in whale adapted for swimming and in bat for flying. 

Flippers in penguins and dolphins, Eyes of octopus and mammals represent convergent evolution

Brain in vertebrates ---Divergent evolution. Flippers in penguins and dolphins-convergent evolution

Bones of forelimbs in vertebrates--Divergent. Wings of butterfly and birds --convergent
