Explanation:

Environmental changes can cause certain traits to be favored through natural selection. Natural selection acts on the existing variation within a population. When the environment changes, the selective pressures change. Traits that were previously neutral or even disadvantageous may now become advantageous. Over time, this can lead to changes in genetic variation within the population as the alleles (versions of genes) associated with the favored traits become more common.

Answer:

Changing environmental factors can cause certain traits to be favored through natural selection. This can lead to changes in genetic variation.
