Do you think the wings of a galapagos cormorant are vestigial structures? explain your answer using evidence from the article.

Yes, the wings of the Galapagos cormorant are vestigial.  

Explanation:

The Galapagos cormorant is also called the flightless cormorant is a cormorant exclusively found in the Galapagos Island. It is specific as it is the only cormorant that has lost the tendency to fly. The wings of the bird are about 1/3rd the size needed for a bird to fly. The breastbone keel, that is, the location where the birds’ accord the big muscles required for flight is also substantially diminished. The changes would have taken place generally due to mutation with time.  

Yes, the wings are vestigial structures because they are still apart of the birds' bodies but they can't use them for flight. The article says it's because of a genetic mutation.
