Question

a group of moths lives in a forest where the trees were originally dark - colored due to pollution. most moths had dark wings, which helped them blend in. over time, environmental policies reduced pollution, and tree bark became lighter. some moths were born with lighter wings due to genetic variations. over generations, more moths had light - colored wings. what is the most likely explanation for this trait shift within the moth population?

the moths with light - colored wings survived better and had more offspring like them.

the moths developed light - colored wings because the environment changed.

the moths all started having light - colored wings because of a sudden gene change.

the moths decided to have babies with light - colored wings to survive better.

Explanation:

This is an example of natural selection. Moths with light - colored wings had a survival advantage in the new, less - polluted environment with lighter tree bark. They were better camouflaged, survived more often, and passed on the light - winged trait to their offspring.

Answer:

The moths with light - colored wings survived better and had more offspring like them.
