Here's why:
* Early Examples: Practices like bread making and brewing beer, involving the use of microorganisms, predate recorded history and can be considered early forms of biotechnology.
* 19th Century: The 19th century saw crucial discoveries like the understanding of fermentation by Louis Pasteur and the development of pasteurization, paving the way for modern biotechnology.
* 20th Century: The 20th century brought significant advancements like the development of antibiotics (penicillin), the discovery of DNA structure, and the emergence of genetic engineering techniques.
Therefore, rather than a single year, biotechnology has developed over centuries, with key milestones and innovations contributing to its evolution.
It's more accurate to say that biotechnology emerged as a distinct field in the late 20th century with the development of recombinant DNA technology and its applications in medicine, agriculture, and industry.
