B. Artificial selection is selection by humans rather than the environment.
We human can select to breed dogs and wolves together to make a better species. We breed grain and grasses together to create a better yields. We bred cattle, sheeps, and horses to be stronger. Artificial selection is based on what the person desire the traits to be; it is not always for a better fit. We human are responsible for breeding the traits we want. This is artificial selection.
