Detailed explanation-1: -For example, broccoli, cauliflower, and cabbage were all derived from the wild mustard plant through selective breeding. Artificial selection appeals to humans since it is faster than natural selection and allows humans to mold organisms to their needs.
Detailed explanation-2: -In animal breeding, techniques such as inbreeding, linebreeding, and outcrossing are utilized. In plant breeding, similar methods are used. Charles Darwin discussed how selective breeding had been successful in producing change over time in his 1859 book, On the Origin of Species.
Detailed explanation-3: -One of the oldest and most widely documented examples of selective breeding for food is the selection of tall growing (for easier harvesting), disease resistant wheat, which yields large amounts of grain.
