Are flippers of penguin and dolphin homologous or analogous? What type of evolution has brought such a similarity in them?

Solution

Analogous organs have similar functions but different origins. Flippers of penguin and dolphin have a similar function (helps in swimming) but different origin so they are called analogous organs. Penguin and dolphin are not closely related to each other but evolved similar traits (flippers) which represent convergent evolution.
