Biotech Industry Overview - History of Industry


"This document is not an official pronouncement of the law or the position of the Service and cannot be used, or cited, or relied upon as such."

2. History of Industry

The history of biotechnology begins when primitive humans became domesticated enough to breed plants and animals; gather and process herbs for medicine; make bread and wine and beer; create many fermented food products including yogurt, cheese, and various soy products; create septic systems to deal with their digestive and excretory waste products, and to create vaccines to immunize themselves against diseases. Archeologists keep discovering earlier examples of each of the uses of organisms by humans, but examples of most of these processes go back to between 5,000 and 10,000 BC.

It is evident that biotechnology in the past concentrated on the production of food and medicine and solving environmental problems.

Modern biotechnology, based on recombinant DNA technology, finds a similar distribution in the use of recombinant organisms to serve in the production of food, and medicines and solving environmental problems. Introducing genes into organisms, breeding organisms to form new variants, or treating organisms with specific compounds may accomplish this. Biomedicine is medicine based upon the principles of biology and biochemistry.

Biotechnology-derived products have the potential to positively change our society, from improving health care and increasing agricultural products to producing a cleaner environment.

Though a quarter of a century old, the industry remains relatively small compared to the traditional pharmaceutical industry, which bases its approach to drug development more on chemistry than on genetics.  Most biotechnology companies are still in the start-up mode, which means they are not yet profitable and instead are consuming investors' capital on research and development in order to develop new products, such as human therapeutics.
