How did the wings of *Waimanu* primarily differ from the wings of modern penguins?

Answer

They retained small wings, not fully adapted for efficient, sustained swimming locomotion.

Unlike modern penguins with specialized flippers, *Waimanu* possessed small wings whose skeletal structure indicated they were not yet fully adapted for the powerful underwater propulsion seen in later species.
