Maryann Mott National Geographic News January 25, 2005
quote: Scientists have begun blurring the line between human and animal by producing chimeras—a hybrid creature that's part human, part animal.
Chinese scientists at the Shanghai Second Medical University in 2003 successfully fused human cells with rabbit eggs. The embryos were reportedly the first human-animal chimeras successfully created. They were allowed to develop for several days in a laboratory dish before the scientists destroyed the embryos to harvest their stem cells.
In Minnesota last year researchers at the Mayo Clinic created pigs with human blood flowing through their bodies.
And at Stanford University in California an experiment might be done later this year to create mice with human brains. ... What's caused the uproar is the mixing of human stem cells with embryonic animals to create new species.
Biotechnology activist Jeremy Rifkin is opposed to crossing species boundaries, because he believes animals have the right to exist without being tampered with or crossed with another species.
He concedes that these studies would lead to some medical breakthroughs. Still, they should not be done. ... Cynthia Cohen is a member of Canada's Stem Cell Oversight Committee, which oversees research protocols to ensure they are in accordance with the new guidelines.
She believes a ban should also be put into place in the U.S.
Creating chimeras, she said, by mixing human and animal gametes (sperms and eggs) or transferring reproductive cells, diminishes human dignity.
"It would deny that there is something distinctive and valuable about human beings that ought to be honored and protected," said Cohen, who is also the senior research fellow at Georgetown University's Kennedy Institute of Ethics in Washington, D.C.

quote:
"There are other ways to advance medicine and human health besides going out into the strange, brave new world of chimeric animals," Rifkin said, adding that sophisticated computer models can substitute for experimentation on live animals.
(Emphasis mine)
...Right...
quote:
David Magnus, director of the Stanford Center for Biomedical Ethics at Stanford University, believes the real worry is whether or not chimeras will be put to uses that are problematic, risky, or dangerous.
Less problematic, risky and dangerous then, say, nerve-gasses? I don't know, i just don't see the problems in this whole thing. I don't believe there's anything "distinctive and valuable" to homo sapiens other then the distinctiveness and value we as a society give to it.
It might actually spark some interesting debates on what it means to be human. I'd love to see some religious nuts arguing against equal rights for mice-man because they don't have souls. Or some environmentalist fundy ranting about the "unnaturalness" of it all right before stepping into his automobile and driving off to go home and cook a veggie-burger on his induction-heater that's powered by the solar panels on his roof. Now that's entertaining.
I don't think this sort of thing will be considered problematic, risky, or dangerous for very long. Probably some people will worry about it, but then they'll flip on their TVs and watch the latest stupid reality show or sit-com and they'll just forget about the whole thing. Hmm, come to think of it, maybe i shouldn't write posts when i'm in such a cynical mood. |

Agree with Plyss, although I might not have some few years ago.
If nothing else, it shows that we are not as far removed from the natural world as we might think. Or hope.
Thanks, Isaiah.

This is really interesting. Was the objective or profit, in making these 'chimeras' ever mentioned? Having resently seen the result of an apparent 'group death wish,' am coming to accept the notion that humanity's time on the stage is limited and drawing to a close. Leads me to wonder, "What will come forth, next?" What a joke to play on the next (?) player's evolutionists. There would be a clear and real evidence, of a deliberate intervention, {perhaps of a Divine nature..?}, in the DNA , uh, phylogeny. Although loosing favor now, there was a bit of speculation, suggesting it would come in the form of AI from our computers or more likely our computer directed factories.
edit for spelling *sigh* |

Wow. Interesting. I say go for it. Maybe we should quit worrying about what's at the bottom of the slippery slope until we're closer to it.
There might be some increased risk of future diseases that cross species' barriers, but that is true for lots of human activities like animal tissue transplants into humans and new roads through the rain forest. |

Don't forget the implications of the reverse. Many animals are not vulnerable to some of the worst pathogens that effect humans.
It's a very interesting area of inquiry.

Dave, are you thinking what I'm thinking?
Besides, Dave, haven't you read the Hitchhiker's Guide to the Galaxy? It wouldn't make sense for mice to try to take over the world. They commissioned it's construction! |
