HELP ME - The shape of songbird wings affects the efficiency of flight. Birds with more pointed wings fly long distances more efficiently, and birds with more rounded wings fly short distances more efficiently. Over the last 100 years, large portions of forests have been cut down, forcing many songbirds to travel to other forests to find mates. Which of the following evolutionary changes has most likely occurred in these bird populations as a result?
A. Bird wings are more pointed than they previously were.
B. Bird wings are more rounded than they previously were.
C. Young birds learn to use their pointed wings later than they previously did.
D. Young birds learn to use their rounded wings earlier than they previously did.
