Explanation: 

Detailed explanation-1: -The meats sold today are the result of the selective breeding of chickens, cattle, sheep, and pigs. Many fruits and vegetables have been improved or even created through artificial selection. For example, broccoli, cauliflower, and cabbage were all derived from the wild mustard plant through selective breeding.

Detailed explanation-2: -Chickens are selectively bred in order to amplify certain characteristics deemed desirable for human use. Chickens are commonly raised for their meat, eggs, or companionship when kept as pets. Some breeds grow quickly while eating relatively small amounts of food, making their flesh more cost-effective for farmers.

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.
