About This Answer
Birds have two wings adapted for flight, gliding, or swimming depending on species. According to ornithologists at the Smithsonian National Museum of Natural History, wings evolved from dinosaur forelimbs. The American Museum of Natural History documents how wing structures vary among bird species. Biologists note that even flightless birds like penguins and ostriches retain two wings. The two-wing configuration represents a fundamental adaptation in avian evolution.
