GMO= artificially spliced DNA, mixing multiple species DNA, to get desired traits or response.

Humans could be GMO as well, actually we probably are at this point, either by design or by events of "micro evolution", our bodies adapting to GMO's in our diets and environment at an excellerated rate.

The evidence suggests that we are being modified in one way or another, look at all the evidence; autism, mental illness(60% of the US population is on drugs for mental disorders, from anxiety, depression to bi-polar). That is not normal, we are human beings, we live in an environment we were built to enhabit, the majority of the population should not need drugs just to cope with life, there is no logical reason for it.
