Detailed explanation-1: -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-2: -Artificial selection is an evolutionary process in which humans consciously select for or against particular features in organisms – for example, by choosing which individuals to save seeds from or breed from one generation to the next. People have been artificially selecting plants and animals for thousands of years.
Detailed explanation-3: -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.
Detailed explanation-4: -Artificial selection has been practiced for thousands of years by humans to make improvements in plant species. Mass selection is one of the earliest methods of artificial selection that enabled domestication of crop plants.
Detailed explanation-5: -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.
