What are GMOs?
Genetically modified organisms (GMOs) are organisms that have been modified in a laboratory in order to produce a specific result. For example, many types of food sources, especially corn and soybean crops, are genetically modified in order to withstand herbicides and insects. This method stems from the concept of selective breeding and dates back to at least 8000 BCE, although genetically altering DNA didn’t happen until 1973.
Austrian monk Gregor Mendel is credited with identifying the founding principles of genetics when he crossbred two pea breeds in 1866. In 1922, hybrid corn made its commercial debut, while plant breeders discovered how to alter DNA with radiation and chemicals in 1940. After 1973, the FDA approved insulin in 1982 as the first genetically engineered product for human use. However, genetically modified food didn’t get FDA approval until 1994, when a GMO tomato became the first to go commercial. While on the surface it appears that GMOs are 100 percent positive, they have been surrounded by controversy for decades.
