Explanation:
Humans, since they started taming wild cows, began artificially selecting the cows that produced more milk because this trait is desirous. Humans depended on milk for food. This artificial selection by humans ensured that traits for cows for more milk production were preserved in the population of tamed cows. Humans also went further to breed the cows that produced more milk leaving out those that didn’t. Just like natural selection, artificial selection favors the desired traits in a population.
