ALL LIVING THINGS ARE GMOs. For millions of years, viruses and bacteria have been splicing their genetic material, and that of other species, into host genomes, and the result is an ancient and ongoing genetic fossil record of species heterogeneity. This natural GMO experiment occurs every day in every species. This fantastic collage of genes and fragments defines all living creatures. Rational genetic design by man represents but a needle in a vast haystack of natural experiments.
