Human needs and values guided these manipulations and search for knowledge. Plants and animals were selectively bred for their usefulness, and microorganisms were used to make food items such as beverages, cheese, and bread.

Early farmers noted that they could improve each succeeding harvest by using seeds from only the best plants of the current crop. They noticed that plants that gave the highest yield, stayed the healthiest during periods of drought or disease, or were easiest to harvest tended to produce future generations with these same characteristics. Through several years of careful seed selection, farmers could...
