Question

In the case of the peppered moths in England, when Kettlewell set up cameras to document that more white or black moths were eaten by birds on clean or sooty trees, he was verifying which factor involved in evolution by natural selection.

Answer 1

Answer: Some individuals are better adapted to the environment

Explanation:

In case of peppered moth, in England cameras was put to see whether white moth better suits the environment or the black moths.

Earlier there was more white moths and then after industrial revolution they were easily seen in smoky environment due to pollution.

The moths evolved and started to appear grey so that they can hide from the predators that prey on them.

This proves that some individuals( grey moths) are better suited in the environment as they match the color of the environment.
