Final answer:

Decreased wing length in barn swallows is likely a result of sexual selection, where traits for mating success can evolve independently of survival benefits.


Explanation:

Decreased wing length in barn swallows is most likely a result of sexual selection, where traits not necessarily linked to survival become preferred for mating success. This phenomenon, known as sexual selection, can lead to the development of characteristics that are not advantageous for survival but enhance reproductive success, such as smaller wings in male barn swallows.
