Thread: Embryo Selection

Hi, folks!

Read about embryo selection here:

http://en.wikipedia.org/wiki/Preimpl...etic_diagnosis
http://www.brown.edu/Courses/BI0032/gentherp/IVABC.htm

Note the 'ethics' section in the wikipedia article, for this is where this discussion will be about.

My question to you guys is:
Is embryo selection ethical? Is it morally acceptable or morally wrong? And if it is acceptable: where do we draw the line? And more importantly: why?


And.... You may start debating!

Fun ey?


Mmmkay... Bye!

Until someone gives me a clear reason why this is ethically wrong, I think it's a beautiful opportunity.

If we're talking about designer babies, I can think of four reasons that this might be a bad idea.

1) The technology will probably not be readily available to poor people. This creates potential for the wealthiest families/countries to produce smarter, stronger, healthier children than the poor families/countries, creating a self-perpetuating cycle of eugenic disparity between the rich and the poor. This could lead to a new form of feudalism, except now the aristocrats really are superior. Call this the 'genetic aristocracy' effect.

2) Society and the market may decide that babies should be designed as a matter of moral principle. It would start with society demanding that all babies are screened for disease genes, but then they may demand that babies are as smart as possible, or strong, etc. This may lead to genetic discrimination. Call this the Gattaca effect.

Interestingly, a law was recently passed in the US outlawing genetic discrimination. However, this should be taken more as a sign that it will happen and congress knows it, rather than a sign that it won't.

3) If the technology is developed, governments may use it to produce (probably covertly) a generation of children better suited to serving their own ends, which would be children that are healthier, stronger, dumber, and more prone to indoctrination. Over time, using a combination of eugenics and aggressive indoctrination, it may be possible to create a lower class of humans, barely conscious, bred only to fight war and keep the peace (and trust God/the government). Call this the 'anti-aristocracy' effect.

4) Evolution works best when you don't interfere. Humans may think they know nature's tricks, but no one is cleverer than evolution when it comes to survival. By creating a generation of designer babies, we may inadvertently select out a key gene the immune system uses to fight off viruses. Because of this, humans may not be able to fight off the next plague, and this would make humanity more vulnerable to extinction.

hmmmmmmm

im not sure embryo selection necessarily makes for a smarter/healthier/better off human being

babies aren't born with fully developed brains. the brain is still growing and developing as a baby and as a child and as a teenager. . .what really makes the difference is how they are taken care of in early life. what foods their parents feed them - are they eating junk food and drinking sodas by the age of one? are they getting enough sleep? are their minds being stimulated or are they left to rot in front of the tele?

you know, there are some studies showing how certain groups of minorities are doing worse in school. and its not because of genetics that minorities some how are inferior brains. it comes down to nutrition. some families are too poor to afford to eat healthy. poor family means poor nutrition. poor nutrition means its hard to focus at school. fish has been called brain food for a reason.

with all the newer research we have done, we understand that 1. this is a left brain society that practically suppresses right brain thinking. 2. we are ALL essentially left brainers and can learn to be right brainers 3. your lifestyle has a greater impact on your intelligence and performance as a human being than.....dna. anyone can drink them self stupid even if hes born a genius.

but you know, if the parents want to do this thats fine. I know at least in my immediate family probably the only bad genes we have are bad eyes. in other families there are a host of genetic diseases. maybe some people have more to be concerned about than others

but my real problem is WHO is screening and WHAT are they screening for. An 'anomaly' can be a GOOD thing for example. Thats how evolution works right? Autism is pretty strange, but those individuals can lead fascinating and fulfilling lives and have proven to be able to advance in areas that normal people can't. I would just be worried if we ever get to a point in our history where we are suddenly afraid of any sort of anomaly we don't understand in our dna. Especially at the same time, when were being told only a portion of our dna is active

who has the right to decide what is good and what is bad genetics? where are the lines there and how far will that go?

Of course I'm talking about potential. Obviously the best genes in the world won't help you if you're malnourished. But, given a good environment, good genes can make a difference, and some people might try to exploit this. I say "might" because we don't yet know how much variation you can get out of small genetic modifications. My 4 scenarios are just some things to think about, not predictions.

Plus, if the technology got advanced enough, than the government, (or people,) could remove or alter certain alleles to actually affect personality to thier own ends, suppress certain emotions, (Equilibreum anyone?,) create dispositions to certain types of things, what have you.
