Do penguins have fins

Penguins, like all birds, have wings. The difference is that these wings help them swim, not fly.

Some sources state that the wings are vestigial, meaning they have become useless for any purpose. This is not the case, as the penguin uses its wings as flippers. Nonetheless, as birds have wings, and penguins are birds, then the logical outcome is that penguins have wings; they are not flippers.
