I could go into how Eugenics was created to justify slavery and divided human beings into ridiculously psuedo-scientific social groups known as 'races', and how it led to the Holocaust, but for simplicity's sake what constitutes "better" is subject to unlimited opinions and perspectives, making the whole idea nothing less that completely ignorant of human nature.

Purely biologically speaking there is nothing wrong with it. However to rely only on this single race for human survival would be an error. The power of evolution is to have a multitude of mutations available at all times. As soon as the environment changes, chances are good that at least a part of the population can adapt and procreate. Having a mono culture of human beings would be a terrible risk for the species.

It is immoral and unethical

Well, for one thing, human beings already think themselves too close to immortal god-like creatures. Playing with the natural order of things like that is bound to have disastrous results. It's high time we accept things for what they are, life for what it is. If we weren't so preoccupied with extending our lives, we'd be more interested in actually living. Quality over quantity and all that.

Watch Star Trek --- Kahn was a eugenics project.

Because it is all subjective. What is 'better' to one person or group is 'not so good' to another. What classifies a person as beautiful? Their insides or their outsides? What is the optimal color? What is the best height, weight, etc? It's a persons uniqueness that sets them apart from everyone else. You start to be selective and you begin to eliminate these unique features that separate or identify people as individuals. You begin to have a group that looks alike, thinks alike, and in fact are so alike that they could become related to everyone else. You could get to the point where everyone is related and you begin to degrade the genetics and result in a higher level of birth defects... then comes the quandry of what to do with those 'defective' babies that come from 'selective' breeding? It's a whole big can of worms that people already do on a small scale, on their own, when they marry for money, for bloodline, when they marry for looks, it's peoples own version of selective breeding based on their own definition of 'better'. Anytime you let someone define human characteristics or traits as being better than others based on human thinking, you will split society into the acceptable and the unacceptable lending weight to segregation and division and group pride and group hate. More bad than good would come out of selective breeding of the human race on a large scale.

It makes the creation of life a huge scientific project, to be done in controlled environments with controlled objects and a controlled outcome..there is no soul/spirit/heart in that..it is all test tubes, microscopes and death of one set of genes or another. It is no different from "ethnic cleansing" or what Hitler tried to do by eliminating the Jews, or what the Turks tried to do by eliminating the Armenians. It is cold, calculating and dreadful!:(

It's all well and good until you get classified into an "undesirable" category. How do you think it would make you feel? Who has the right to tell you not to create children? The whole basis for eugenics is subjective discrimination - and whose standards are "right?" You even used one of the key words in your question - "better." Who determines what is "better" - and benefitting whom? I'd prefer to let nature take its course, thanks. The Nazis were the last main experimenters with eugenics, it should be recalled.

As eugenics was practiced in the past, It has been clearly shown that there is a high potential for abuse in such a practice. However, you must remove yourself from your selfish emotional state of thinking when you ask yourself this question: "How would you feel if someone told you that you were not allowed to have children of your own?" You must instead use logic when answering this question. If you pre-existing medical issues which are known to be passed on through your genetic information... Then why should you be allowed to breed? What is wrong with making an effort to reduce genetic medical issues by implementing selective breeding, and not allowing such people to breed? If you use your emotions to guide you to an answer, then my opinion would be worthless to you. If you use a more logic based way of thinking: "What is wrong with making every effort to reduce people from passing on genetic problems up to and including preventing such people from breeding?" By the way, for all selfish breeders out there who must have a child of their own; I suggest that you first examine the statistics of orphaned and abandoned children who actually need a parent(s) to take care of them. P.S. -- I welcome anyone to challenge me on this subject, but please check your emotions at the door. (Emotion has always stood in the way of progress in our society)

selective breeding will always favour one group over another. the favored group in their struggle for perfection and recognition will seek the demise of another less favored group resulting in racial discrimination and other social injustices.

We would have another Hitler on our hands. That was what Hitler was all about. Racism causes injustice such as slavery.

It's happening right now. Who knows what the result will be. I won't live long enough to see the results. +5

There is quite a bit about the american eugenics movement if you do a google search. A representative site is http://www.eugenicsarchive.org/eugenics/list3.pl . Eugenics was used to justify, for example, a forced sterilization that was upheld in the U.S. Supreme Court. Majority opinion Oliver Wendell Holmes said "three generations of idiots is enough". The movement died quietly due in part to its eerie resemblance to the views of Adolf Hitler. Eugenics gets especially ugly when it comes down to just who determines what makes a superior strain, and when the thinning out of supposedly inferior ones becomes a genocide.

ask captain Kirk, bet he has a lot to say on the subjeck

Didn't you learn enough from the history of slavery in America to see the problems selective breeding called eugenics caused? 1. Who is going to decide what people they will breed to do what? Probably those in control--the majority or those with the most money and resources! 2. To what degree will they carry the process of doing this? Look at what Hitler did? 3. What if you are on the first list of not being "good enough" to breed? 4. How will the "idea" of freedom and the Bill of Rights survive?

Because humans cannot agree what precisely is "better".

One: it reduces the gene pool, which eventually yields genetic fade. Two: restricting the gene pool reinforces the bad traits and weaknesses as well as the strong and "good" ones, whatever "good" means. Charles II of Spain was the result of selective breeding. Here's one site: http://www.xs4all.nl/~monarchs/madmonarchs/carlos2/carlos2_bio.htm Three: It is a monstrous invasion of privacy and a total suppression of personal choice. Bureaucrats decide who may reproduce and who may not; those who may do so are forced to do so against their will. Four: one inevitable concomitant is forced sterilisation of those whom the bueaucrats deem "unfit" to reproduce.
