GM animals

Have we gone to far in genetically modifying animals?mouse with ear.jpg Well do you think this is normal? This is real you can go look it up but I am telling you as disgusting as it is you are in fact looking at a mouse with a human ear on its back. But it gets stranger then this. Ever heard of a Belgian blue cow well they are huge and incredibly muscled cows produced only to get more meat out of them.  belgian-blue-bull.jpgThis is what they look like. Huge muscled things only produced to be later slaughterd. If you are strongly against or you strongly agree that GM animals are good reply with your reasons. Nat

    Re: GM animals

    Is selective breeding GM ? Because I'm afraid that the Belgian Blue has not had its genes played about with it is a 'sport' that has a natural mutation that enables it to have huge muscles (therefore more steak yay). The 'Vacanti' mouse once again is not geneticaly modified It has a ear shaped polyester fiber mould seeded with bovine cartilage inserted under its skin. The mouse itself is from an imunocompromised strain that usefully does not reject implant and the like.

    The actual amount of Genetically Modified animals is actualy very small most animals under this banner are actualy sports or mutations that would die out in the real world but are very useful in the laboratory. I champion the rights of animals and go out of my way to avoid harming even an ant, but I live with the fact that I eat meat and rely on drugs that have been tested on animals to live a normal life. A good number of the World's population would not be here without animal testing even animal right activists i'm afraid.

        Hi Nat. It is a great question that really affects a lot of people today. I actually think that genetically modified crops are a greater threat (and these ones really are mucked about at a Gene level) as there seems far less excitement at first sight. Although we do once again have to temper this with the fact that these scientists are not actually trying to kill us, just produce plants that are disease resistant and heavy croppers. It's all a 'can of worms' really and as a child of the new millennium it will be something that directly effects you and your children.

            Hi Natalie.

            Yes I've heard of Golden Rice and I agree it could save lives but at the same time people on subsistence rice farming possibly could be better served with education on getting their vitamin A (I think) from other sources. I am no scientist I work in Scenic Arts, love natural history (I contribute on the NHM's Bug Forum on this site) and I read all the time and luckily have a good memory, so my advice to you is to read everything, fact and fiction, listen to debate and try to see what's behind every breakthrough and headline. It is almost impossible to find an impartial view on anything, sometimes very clever sounding people can be talking absolute rubbish and sometimes you will have to completely change your stance on a subject (never be too embarassed to do this, but don't do it every day) so it is down to you to read what all sides say on a subject and form your own opinion. Although I would have to say that as a rule of thumb mums tend to be right in the long run .

            The Chinese have now produced GM cows that produce breast milk. Not sure how I feel about that!

                Yes, sorry Nat', they produce the equivalent of Human Breast Milk. Not absolutely sure that it's a good thing. It might save lives but possibly could be another way of introducing the part protein that causes BSE into the food chain. But what do I know as I said before I'm a scenic artist so it's my job to turn fantasy into reality and these new animals that are being created might be just the start before we start mucking around with the Human Genome.

    Re: GM animals

    Hi Nat Very interesting question!  Some GM creatures are really weird: pigs that fluoresce bright green under UV light for example - because they have had a gene from (I think) a jellyfish inserted into their genome.  I'm not sure about getting human milk from cows either. 

    But, in spite of the risks, I don't really see anything “morally” wrong with GM crops if they help produce better quality or disease resistant food plants.  Especially if they feed poorer people.

    As Lewis said, the Belgian Blue cow is not GM, but the result of a mutation.

    You said: "Just think it is a little bit cruel to produce an animal that is not natures evolutionary choice just so we can invest more because the animal has more meat on it." I agree that it seems cruel, because such mutations are usually connected with health problems.  That is, if the animal is allowed to live long enough before being turned into beef.

    However, part of your comment shows a misunderstanding that even qualified scientists often make. The Belgian Blue mutation is not evolution, because there is no new genetic information added.  What seems to have happened is a fault in the mechanism that “switches off” muscle growth when the muscles are fully developed. It is rather like the timer that switches street lights off when daylight comes.  If there is a fault in this mechanism the light will remain on all the time – wasting electricity. 

    You could call it “devolution”, not evolution…
