re: #26 EiMitch

All true.
And my main point is the most relevant to the argument: GMO plants are not the same thing as the age-old process of hybridization.
I adore Dr. Tyson, but he is essentially saying they are the same thing and they are not.
In producing hybrids, one selects attributes of a plant to promote by cross pollination, such as Mendel and his pea plants, or the process of developing modern day corn from the original wild maize.
GMO is actually splicing unrelated genes into a different DNA, as is the case with Bt and Roundup Ready, to produce new plants. An artificial hybrid, if you will, that could not occur by merely selecting attributes to promote by cross fertilization.
I really wish this was explained better by those who should know better.
