Artificial selection is a process where humans intentionally breed plants or animals for specific traits. This method allows people to enhance desirable characteristics, such as size, color, or yield, in crops and livestock. By choosing which individuals to mate, humans can influence the genetic makeup of future generations. This practice contrasts with natural selection, where environmental factors determine which traits are advantageous for survival. Examples of artificial selection include the breeding of dogs for various sizes and temperaments or the cultivation of corn for higher productivity. Over time, these selections can lead to significant changes in species.
