The history of biotechnology is found parallel to the civilization history of man. Use of biotechnology can be traced back to the earliest human society. Human realized that, to get good and continuous food they should plant their own crops, breed and domesticate their own animals. Study of biotechnology began when human discovered to produce yogurt and cheese from fermented milk. Early human made wine or beer from fermented juices of fruit, sugarcane and malted barley. Since early times of civilization, human are naturally acting as unqualified biotechnologists by baking soft, spongy and tasty bread and bakery items. The first farmer who grafted a more beneficial plant over the other less beneficial plants to increase his yield and quality was a performing biotechnologist.
Rapidly growing human population, led the human to develop new animals with dream characteristics. Scientists planned to grow more nutritive and naturally pest- resistant crops. Researchers hoped to develop unlimited and purest sources of human medicines. Human found the natural ways to remove pollutants form environment and to increase the fertility of the soil and kill insect pest.
