UN Convention on Biological Diversity, Art. Bioengineering is the application of the principles of engineering and natural sciences to tissues, cells and molecules. This can be considered as the use of knowledge from introduction to biotechnology thieman pdf with and manipulating biology to achieve a result that can improve functions in plants and animals. Indeed, the cultivation of plants may be viewed as the earliest biotechnological enterprise.
Through early biotechnology, the earliest farmers selected and bred the best suited crops, having the highest yields, to produce enough food to support a growing population. 1857, it is still the first use of biotechnology to convert a food source into another form. Darwin added to that body of work with his scientific observations about the ability of science to change species. These accounts contributed to Darwin’s theory of natural selection. For thousands of years, humans have used selective breeding to improve production of crops and livestock to use them for food. In selective breeding, organisms with desirable characteristics are mated to produce offspring with the same characteristics.
For example, this technique was used with corn to produce the largest and sweetest crops. Biotechnology has also led to the development of antibiotics. In 1940, penicillin became available for medicinal use to treat bacterial infections in humans. 1972 by transferring genetic material into a bacterium, such that the imported material would be reproduced. Revenue in the industry is expected to grow by 12.
