Answer :

Final answer:

Artificial selection is a human-driven process of selectively breeding organisms to enhance specific traits. This deliberate manipulation of breeding has led to the creation of various useful plants and animals.


Explanation:

Artificial selection is a process where humans selectively breed plants and animals to emphasize specific desirable traits. This can be seen in examples like domesticated dogs, cats, broccoli, and corn, which have been modified by humans for various purposes.

Through artificial selection, humans play a significant role in shaping the genetic makeup of organisms for traits that are advantageous to them. This process has led to the development of various crops, work animals, and companions that may not survive in the wild without human intervention.

Artificial selection is distinct from natural selection, as it involves deliberate human choice in breeding decisions to perpetuate certain desired characteristics in future generations of organisms.
