Your view of biology is entirely too rigid and overly simplistic. I could give you hundreds of examples from the knockout literature which prove your assumption false.
Yet what I find interesting is you write later on in another post......
Most genes are not vital, they are not killers. You can play with those genes and not destroy an organism.
So which do you really believe Gore? Are you finally leaving open the possibility that the genome can adapt to change?
That is not what I said. You surmised that because it did not kill that the change was okay. I said the effects may not be obvious, but that does not mean they were not detrimental. I said you would not play around that way with the genes of a family member or indeed those of any human. Also, you gave very little details as to the experiment - where it was done in the genome, what were the expected results, what procedures were taken to insure it would work, etc., etc. I already listed some of what scientists know about how to insert changes in a genome. It is not the same as how random mutations would act.
