lol. That is such a flawed arguement. The arguement that DNA from something has no effect on us because we have not turned into the DNA attributes that we eat, it is that of which I would expect from a 5 year old....
And like a five year old I'd like to resolve this argument with violence.
What I actually said is that we don'thave dna from the thing we eat in our genome, we do have junk virus dna but not anything from a ham sandwich.
In my opinion this is all about you opinion. Disease is passed more easily from similar organisms, dim. WHen you eat another person you get sick because they were sick not because you stomach somehow reconizes the source of the meal. Cows don't eat meat, hell they get sick just from eating corn. GM foods are only dangerous when they are altered to do something insane like provide you with a ton of the more toxic vitamins and say, a pesticide chaser. I know enough about evolution to know this has nothing to do with evolution.
