Detailed explanation-1: -Artificial selection, also called “selective breeding”, is where humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection.

Detailed explanation-2: -Artificial selection is the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations.

Detailed explanation-3: -Artificial selection is a breeding process in which a population of organisms is screened for some quantitative trait or traits and those individuals rated highest are used as parents for the next generation.

Detailed explanation-4: -For example, dachshunds were selected to flush out and hunt small animals, while German Shepherds were selected for herding sheep. Modern domestic dog breeds come in such a variety of shapes and sizes that we might well have classified them into dozens of different species if we did not know their history.

Detailed explanation-5: -Farmers and breeders allowed only the plants and animals with desirable characteristics to reproduce, causing the evolution of farm stock. This process is called artificial selection because people (instead of nature) select which organisms get to reproduce.
