Which of the following statements best explains the appearance of the flatwing phenotype among male crickets on Kauai?

A) The flatwing phenotype arose due to genetic mutations specific to the cricket population on Kauai.
B) The flatwing phenotype is a result of natural selection favoring traits that increase mating success in the local environment.
C) The flatwing phenotype is a response to environmental factors unique to Kauai, altering the development of cricket wings.
D) The flatwing phenotype emerged as a result of interbreeding between different cricket species inhabiting Kauai.

The correct option is (B) The flatwing phenotype is a result of natural selection favoring traits that increase mating success in the local environment. The flatwing phenotype in male crickets on Kauai is due to natural selection favoring traits that enhance mating success in the local environment.

Explanation:

The flatwing phenotype among male crickets on Kauai is BEST explained by natural selection favoring traits that increase mating success in the local environment.

This means that the flatwing phenotype likely provides a mating advantage for male crickets on Kauai, allowing them to reproduce more successfully than those without this phenotype.

Therefore, the appearance of the flatwing phenotype can be attributed to the evolutionary process of natural selection in response to the specific environmental conditions on Kauai.
