Detailed explanation-1: -Biotechnology began at least 6, 000 years ago with the agricultural revolution. This early era was characterized by exploiting living organisms in their natural forms or modifying their genetic makeup through selective breeding.
Detailed explanation-2: -The earliest example of biotechnology is the domestication of plants and animals. Domestication began over 10, 000 years ago when our ancestors started keeping plants as a reliable source of food.
Detailed explanation-3: -Humans have used biotechnology since the dawn of civilization. Egyptians used yeasts to bake leavened bread, the Chinese developed fermentation techniques for brewing and cheese making, and the Aztecs used Spirulina algae to make cakes.
Detailed explanation-4: -For thousands of years, humans have been using traditional modification methods like selective breeding and cross-breeding to breed plants and animals with more desirable traits. For example, early farmers developed cross-breeding methods to grow corn with a range of colors, sizes, and uses.
Detailed explanation-5: -The term biotechnology was used for the first time by Karl Erkey, a Hungarian Engineer, in 1919.
