Go to the aquarium section of any pet store. You will see tanks of fresh water fish that glow with neon-bright colors under florescent light. Those fish are products of a DNA change... and will pass it down to their offspring.
That's fine so long as they live in a fish tank, where basic survival isn't required. However, take those fish to a small pond and see how many survive after a few weeks. Somehow, the ability to "glow" in bright colors might not contribute to their survival in nature. :>)
We are doing a similar experiment with 2 BILLION people world-wide, including about 70% of all Americans. We just changed the DNA in their liver and possibly in their reproductive system. Now... let's see how well they do in nature?
