The wing of a penguin is homologous to the arm of a human.
Homologous organs refer to organs of different organisms that are structurally similar but functionally different.
The wing of a penguin and the arm of a human are structurally similar because they are both built on the same pentadactyl or five-digit plan.
Despite the structural similarity, the wing of a penguin and the arm of a human are adapted for different functions. While the wings of a penguin are used to propel the animal in water by flapping them together, the arms of a human are adapted for several functions, including swimming when necessary.
