Every head of livestock we consume is a GMO. Every ear of corn we consume is a GMO. Wheat, the same. And so on. When humans domesticate anything, they take control of its breeding, and that of course modifies its genome.
The only difference is that we've GMO'ed them using nature's slow method, rather than introducing them.
