Genetic Engineering and Cloning
Genetic engineering and cloning are popular topics in science fiction. They have been featured several times in Star Trek, with a focus either on the dangers of "playing god" in general, on the rightfulness of such a procedure, or on the subjects or victims in particular. This article sorts out the available evidence, points out inconsistent statements and attempts to find a general trend how Star Trek is dealing with the topic.
TOS: Space Seed Genetic engineering is the subject of a Star Trek episode for the first time in TOS: "Space Seed", in a plot thread that is continued in "Star Trek II". Khan and his company were genetically engineered to be superior to other human beings in most respects. It is uncertain to what extent their physical and mental strength has been enhanced, what was the actual purpose of their creation and what has become of possible other genetically engineered humans of Khan's time. But this isn't really of importance in the course of the episode and the movie. What we learn is that Khan and his followers assumed dictatorial powers in several countries of Earth and were finally defeated in the Eugenics Wars. Clearly the idea of "super-humans" is frightening most of the Enterprise crew. The knowledge about the horrors of Khan's regime from the history books fits with Khan's grandiose habits and with his fascist stance that becomes obvious in the dinner with the ship's crew. The impression is created that genetically improved humans have an intrinsic ambition to rule over naturally gifted humans. Overall, the criticism about genetic engineering in the episode is quite concrete. Rather than a general condemnation of tampering with human DNA, the result is criticized here: genetic engineering, although it might be tempting to improve humanity, goes along with bad side effects and creates criminals. Only Lt. Marla McGiver, who falls in love with Khan, is positive about Khan's nature, but she is rather love-sick than having a rational view on genetic engineering.
TNG: Unnatural Selection The second-season episode "Unnatural Selection" is TNG's first and worst take on genetic engineering. The stance put forward here is worrying, to say the least. On the remote outpost Gagarin IV, scientists are breeding "perfect" children. These children are growing extremely fast, they are immune against any known illness, and they even possess telepathic or telekinetic abilities. The scientists are keeping the children in isolation and in spite of all the obvious "success" they don't really know what they are doing by messing with their DNA. That is why they contract the illness of accelerated aging that kills the crew of the USS Lantree. The practice of these scientists is the same as of the creators of Khan, maybe worse. But no one of the Enterprise crew decidedly condemns the irresponsible and inhumane experiments, which we would expect to be outlawed, even if certain other forms of genetic engineering were legal in the Federation. Captain Picard and most of the rest are at most skeptical, and Dr. Pulaski is even fascinated by the idea of breeding humans without illnesses and with all kinds of funny features.
TNG: Up the Long Ladder Quite the opposite opinion on genetic engineering (this time on cloning, to be precise) becomes obvious in TNG: "Up the Long Ladder". The Enterprise crew are very suspicious about the Mariposans, when they learn that their survival has been achieved through cloning. This alone does not bother the crew very much, though. But when Riker and Pulaski discover that they have been cloned by the Mariposans against their explicit will, they don't hesitate and agree that Riker should kill both clones. It is true that their right of individuality and of integrity, as it is almost certainly granted by Federation laws and probably stated in the constitution, has been violated. Nevertheless, killing one's clone can well be regarded as an act of murder, no matter if the clones are still developing, are not yet "programmed" and therefore not yet self-aware -- and no matter whether cloning is legal or not. Especially Pulaski's stance is peculiar, bearing in mind how she was still rather positive about the bred über-children in "Unnatural Selection". In retrospect, she was either overly hypocritical about genetic engineering as a general concept, or just overly selfish when it came to her personal rights.
TNG: The Hunted Genetically enhanced soldiers appear in TNG: "The Hunted". They were designed by the Angosians to be the ultimate soldiers with unnatural abilities, and they were never meant to be integrated into the Angosian society. Picard condemns the practice of breeding soldiers, but ultimately it is once again mostly the result of genetic engineering that is in the focus of interest, as the soldiers are trying to take over the planet. Still, there is a reconciling tone in the end when it becomes obvious that the super-soldiers are not intrinsically bad and that there may be a peaceful solution of the conflict.
TNG: The Masterpiece Society This episode shows a human colony on Moab IV that is based on a genetic balance, meaning that each member of this society is bred to have certain abilities and characteristics. Whilst none of them is supernatural, selection is clearly a form of tampering with human life instead of leaving that to nature. This is the most controversial treatise on genetic engineering so far, even though once again the practice itself is not in the center of interest. Almost everyone one the Enterprise is not fond of the idea that the natural development of a human being should be replaced with a predetermined career. The critics include Picard who always votes in favor of individuality (especially after his Borg experience), Worf who is opposed to anything unnatural, as well as Geordi who quickly recognizes that disabled embryos would be denied their right to develop. Only Deanna is attracted by the perfect harmony of the colony, which may also have to do with her interest in the colony leader Aaron Conor. But the focus of attention shifts in the following, when it becomes clear that the alleged paradise has been contaminated. It turns into one of the many episodes dealing with the Prime Directive, even though it wouldn't apply here because the settlers are human. In the eyes of the colonist Martin, disturbing the colony's genetic balance by letting some of the colonists leave is even worse than its destruction. This is clearly hypocritical, because the colony would hardly need a genetic balance if all were doomed to die, as Worf and Riker correctly object, but even Picard acknowledges that a paradise is being destroyed. Still, Picard's stance does not really touch the issue whether genetic engineering is wrong or right. Picard merely acknowledges that, irrespective of its inception, this colony has developed its own characteristics, its own culture that deserves to be preserved.
DS9: A Man Alone The episode creates the impression that cloning is anything but commonplace, although the technology is rather well-known. The ethical impact of cloning is not really discussed, as it is just an aspect of a murder mystery here. Yet, we learn that killing one's clone is punishable as murder under Bajoran law, which sheds new light on what Riker did in TNG: "Up the Long Ladder". It is mentioned only in a side note that the clone of Ibudan that Bashir created in this episode is kept alive and is allowed to conduct a normal life. We don't learn far he was developed in the end, how he would gain the necessary knowledge and experience and whether Bashir has a bad conscience for playing god, even if it was unwittingly.
The Jem'Hadar The Jem'Hadar are completely artificially generated biological species bred by the Founders and addicted to Ketracel White. There is no natural procreation, no other nourishment but White, and Jem'Hadar seem to have no hobbies or interests aside from fighting, as seen in many episodes, especially DS9: "To the Death". As they are fighting for the Dominion, Jem'Hadar are an exception among the genetically enhanced individuals. Clearly Starfleet has no bad conscience to let their mortal enemy die by destroying White facilities like in DS9: "A Time to Stand", much less to allow the whole race to become extinct, as there is no natural reproduction.
The Vorta The Vorta are another race created by the Founders. If we believe Weyoun (who may have told Odo a lot of crap in DS9: "Treachery, Faith and the Great River"), they have been developed from a primitive ape-like race and are reproduced by cloning. Damar, Worf and Garak obviously had no bad conscience killing various Weyoun clones. But we shouldn't assume that the life of a clone was of lower value to them. Rather than that, it was made easy because of Weyoun's villainous nature.
DS9: Dr. Bashir, I Presume? Here it is revealed that Julian Bashir has been genetically enhanced at the age of five with the illegal "accelerated critical neural pathway formation". This is the first time that a form of genetic engineering is explicitly said to be outlawed in the Federation, the Eugenics Wars being mentioned as one reason for the restrictive laws. Whilst this is not necessarily inconsistent with previous episodes, it lets appear the experiments in TNG: "Unnatural Selection" in an even worse light. If as little as the improvement of young Julian's abilities is illegal (and will get his father into prison for two years), what about the ruthless scientists on Gagarin IV? Not only should Picard have been disgusted, but it would have been his duty to put all the scientists under arrest for their extremely criminal activities. The case of Bashir's parents, on the other hand, may be understandable to a certain extent. As it is mentioned in the episode, Richard Bashir was frequently switching jobs, and he was obviously never really successful in and content with his life. No one needs to be poor or underprivileged in the 24th century, but with all the wealth and social security it may be still important to have certain capabilities for personal happiness -- and to improve oneself, as Picard would put it. When the Bashirs saw that their son's abilities were below average, they decided to change that. Although the result is clearly unnatural, Julian is quite different from any genetically enhanced human being shown so far. It wasn't even noticed by anyone until he was forced to admit it in "Dr. Bashir, I presume" (although, in retrospect, there is almost no way to explain why he didn't make use of his improved senses in one emergency or another).
The "Jack Pack" As opposed to Dr: Bashir, many genetically enhanced humans are emotionally unstable like Jack, Lauren, Patrick and Sarina, who appeared in DS9: "Statistical Probabilities" and once again in DS9: "Chrysalis". They were subject to similar treatments like young Julian, but it failed in their cases, making them geniuses who are not fit for social life and who spend their lives in what appears to be a mental hospital. In this regard they are a bit like Khan, the Angosian super-soldiers or the Jem'Hadar, only that Khan was clearly villainous and the soldiers were designed to be ruthless and violent. Still, an overall tendency becomes obvious. It is a discriminatory depiction in Star Trek (or it would be one if there were genetically enhanced people in the real world), and once again a warning that genetic engineering may have incalculable side effects, especially if we consider that this won't change after over 300 years of medical research.
VOY: Child's Play Cloning is mentioned only as a humorous side note. The Borg twins wanted to clone Naomi for a science project, as Seven said, but she suggested they should start with something smaller. So they went with potatoes.
VOY: Lineage B'Elanna has never been very happy with the Klingon part of her ancestry. She wants the Doctor to modify the DNA of her unborn daughter so she would look less Klingon, without any medical necessity and against Tom's explicit wishes. She even tampers with the Doctor's program to get him to agree. This episodes reaffirms that genetic engineering is seen as unfavorable. However, like DS9: "Dr. Bashir, I Presume?", it explores the motivation, which in this case is perhaps understandable.
Star Trek Nemesis Here Picard is very negative about cloning, but this may have to do with he himself being the victim. Unfortunately Shinzon, the clone, is an unstable person who is out for conquest. This image matches with the one created of the genetically enhanced Khan.
The Suliban The Suliban, or at least a faction known as the Cabal, are shown as a race obsessed with improving themselves through genetic enhancements. When Dr. Phlox discovers the genetic tampering in ENT: "Broken Bow", it is a reason for astonishment but not necessarily for condemnation. Yet, with the Suliban's elasticity being an opportunity to play with CGI, it is only a side aspect anyway in the pilot episode and the following Suliban arc.
ENT: Similitude This is a remarkable treatise that takes the issue of cloning to a new level. Here the problem is not only "Are we allowed to tamper with what nature has given us?" but also "Can we deny so created 'unnatural' lifeforms the rights that should apply to any sentient being?" Starfleet or Star Trek do not really have an answer to the latter question. This uncertainty complicates the episode, as it adds to the general problem of allowing cloning in certain limited cases, for reasons which were swiftly made up by Phlox and Archer here. Cloning has been outlawed by the Lyserians, probably because their simple procedure using the mimetic symbionts (which obviously requires little to no technology) has been subject to extensive misuse. Cloning, like any kind of genetic tampering, has been almost consistently condemned for several reasons in Star Trek so far. But the discussion usually boiled down to practical and rather superficial questions of cloning. Moreover the clones themselves, just like various other types of doppelgangers, were depicted as threatening, like in TNG: "Up the Long Ladder" or DS9: "A Man Alone". This one-sided impression is eventually corrected in "Similitude" by letting the clone speak for himself. But the basic question is still which person would "deserve" to live, if the chances of survival are about equal. So the possible ethical failure in "Similitude" may not have been cloning Sim in the first place, but rather consciously killing him, even if this was the original intention. In this light Sim's remark that he was meant to die just like Trip was meant to be an engineer and Archer a captain leaves a bad taste. It sounds like false heroism out of a false sense of duty, and this is unfortunately bolstered by Archer's speech at the funeral.
The Augments The episodes ENT: "Borderland", "Cold Station 12" and "The Augments" let the genetically enhanced humans, the Augments, appear in a much worse light than "Space Seed" or "Star Trek II" did. Pretending that they just seek a home for themselves, they ruthlessly kill anyone who stands in their way. Internal conflicts are resolved with the same deadly violence, and their behavior is overall governed by the desire for power and for sex. Clearly the Augments, as strong and "intelligent" they may be, are shown as less enlightened than average human beings, as some of the worst characteristics of humanity are amplified in them. With the exception of the unfortunate Smike, who was arguably different, the Augments were not given a chance to show any positive facet, the honor of being a criminal who shows remorse goes to Soong but not to any of them.
Summarizing, Star Trek remains somewhat consistent with its negative stance on genetic engineering. We could take into account several more cases in which the DNA of crew members was consciously modified, but this was usually to repair mutations, like in TNG: "Rascals" or TNG: "Genesis". The DNA fusion of VOY: "Tuvix" and its reversal is still another case that deserves to be scrutinized separately. Among the above "genetic enhancement" episodes most of all TNG: "Unnatural Selection" leaves a bad taste, because it fails to condemn the most blatant and most ruthless form of genetic engineering.
Overall, it is a disappointment that in the majority of all episodes so far mainly the result of genetic engineering is subject to controversies instead of the procedure itself and the motivation for it. That way the focus shifts away from the general question if man should be allowed to play god, and if only to remove some deficiencies that may occur with natural conception. Only "Dr. Bashir, I Presume" attempts to get to the bottom of this question. However, the "Jack Pack", his four genetically enhanced friends fit into the perpetuated cliché again: that there is something intrinsically wrong with enhanced persons, and that the public needs to be protected from them. It is sad that in most episodes that feature genetically enhancements the subjects are either conceded a minor role or are depicted as villains like Khan. But ENT: "Similitude" successfully corrected this cliché by showing Sim, Trip's clone, as a human being and not only a subject that the crew has to deal with.
Thanks to Bob Lemiszki for reminding me of VOY: "Lineage".
