The teosinte is on the left in each panel. The three ears are teosinte, a corn/teosinte hybrid, and corn.
Basically, any plant or animal that does not look like its wild ancestor is genetically modified. That includes most, if not all, of the foods grown commercially.
What the advanced technology has provided is the means to genetically engineer organisms by targeting and modifying a single gene. Previous genetic engineering methods (hybridization, selective breeding, etc.) never allowed that degree of control; in order to get the one wanted genetic trait involved randomly changing many genes and screening hundreds or thousands of organisms to try to find those with the desired trait while minimizing those with undesirable traits.
As for the vaccines, I have been in medical research for over 20 years, and a large part of my career has been focused on fighting infectious disease. So when I say that vaccines are the most significant medical breakthrough ever, it is because I am very familiar with the various medical breakthroughs that have taken place. Countless millions of people are alive today because they received vaccines as children. In many third world countries, that may be the only medical intervention they ever receive. The problem in the US, and the reason that anti-vax hooey finds so many willing recipients, is that vaccines have been so successful that most young people--millennials, gen Xers, even some boomers--have never experienced or known anyone who has experienced the loss of a loved one from a vaccine-preventable disease. And so they think those diseases are gone, but have no understanding of why they are gone. I will continue to fight against this ignorance for as long as I am able.
The Hopi have genetically engineered corn to thrive in their desert fields. The plants appear stunted but produce ears that are the real thing. They have been at in Arizona, Utah and New Mexico for at it least a thousand years. Hopi corn is derived from teosinte Their village of Oraibi is the longest occupied town in America. It was founded in 1100 AD or thereabouts. The Hopi corn can be seen growing at present
Genetically engineered is not precisely the same is cross breeding to improve plants.
IOW, Monsanto creating Round up ready corn is not the same as cross breeing to create better varieites of corn.
But you, the One Who Knows It All, won’t admit that you are ever wrong.
I don’t give a crap who important and knowledgeable and experienced you are or tout yourself as being; you are not all knowing, and there are many people just as highly educated and experienced in the field as yourself, who disagree with your stand on vaccines as being the wonder magic of all times.
You want to use weasel words to conflate actual genetic engineering with normal, standard cross breeding.
