ORIGINAL: ThatDaveGuy69 I just LOVE the fact that CS has so many molecular biologists as members! Guess what folks: EVERYTHING we eat is a GMO! Here's an example: You like bananas? They've been genetically modified over 100's of years to make the sweet, tasty fruit we know today. You wouldn't recognize must of what we eat today even 100 years ago. Farmers have been cross-breeding crops for as long as there have been farmers. The difference is that today we can do in a lab in a week what took decades in the field. Oh, and since your post is right above this: TeaseAndSpankMe (great name, BTW) insects don't know the difference because from their perspective there isn't any. Hybridization is a different process than genetically modifying foods in a lab. GMO's do have risks to agriculture and our food supply which should be enough to cause concern. To sum up my point of view about tinkering too much with nature is just because we can do something doesn't mean that we should. I understand the benefits and risks alike. I am just too much of a skeptic to fall down on one side of this or the other at this point. Well, there's an interesting point here and hybridization isn't the only factor here -- mutations are, too (which don't involve crossbreeding). The question is: can you look at the genome of a crop a posteriori and determine, without reference to earlier genomes, whether that crop's genotype (or phenotype for that matter) was "made by nature over the course of time" or "made in lab in a much shorter course of time." Note my condition. Of course, if you had access to prior genomes, you'd know, but the point is -- is there anything in and of itself that says "I am a GMO, hear me roar!" To the best of my knowledge, and I'm not a molecular geneticist, the answer is no. You might be able to say the probability it's a lab GMO is greater that it's a natural mutation, but that's a probability of < 1.0. Can a lab introduce bad shit (everyone here should appreciate my scientifically precise terms)? Sure, but since we in principle know what we are doing, much less likely than nature would. Can a GMO bioterrorist do that? Yes, they probably could. But then they'd have to get it into the food supply. Whereas, for example, if you found a human being, with a pig's foot grafted on to his leg, you would know with certainty it was not a natural occurrence. GMOs aren't like that.
