Question

Large and well-developed sternum with keel, in a bird suggests:

• A. Inability to fly
• B. Fast running adaptation
• C. Strong flying ability
• D. Fast swimming adaptation

Answer 1

Answer: (C)

Strong flying ability

In Aves, the keel is an extension of the breastbone or the sternum. The keel provides an anchor for the attachment of a bird's wing muscles. It basically provides leverage or support for flight. Flightless birds do not possess a keel.

So, the correct answer is 'Strong flying ability'.
