Human Cloning

Cloning is in this respect no different from any other new medical technology. Research is required on embryos in order to quantify and reduce the risk of the procedures. Embryo research is permitted in Britain until the fourteenth day of embryo development. Many other Western countries are also actively engaged in embryo research. The thousands of ‘spare’ embryos generated each year by IVF procedures and destroyed could be used to the good purpose of human cloning research.

This argument assumes that we know God’s intentions. Evidently, there is no biblical statement on the ethics of human cloning. Who is to say that it is not God’s will that we clone ourselves ? At least one Hindu writer has indicated that Hindu thought embraces IVF and other assisted reproduction technology (ART). Moreover, every time that a doctor performs life-saving surgery or administers drugs he is changing the destiny of the patient and could be thus seen as usurping the role of God. Furthermore, we should be very wary of banning something without being able to say why it is wrong. That way lie all sorts irrational superstition, repression, fundamentalism and extremism.

This argument is wholly unsuited to the modern age. Society freely allows single people to reproduce sexually, whether by accident or design. Existing lawful practices such as sperm donation allow deliberate procreation without knowledge of the identity of the father. Surely it is preferable for a mother to know the genetic heritage of her offspring, rather than accept sperm from an unknown and random donor? Moreover, reproductive cloning will allow lesbian couples to have children genetically related to them both. It might be better for the welfare of the child for it to be born into a happy relationship, but the high rates of single parenthood and divorce suggest that this is not always possible.

When people resort to talking in wholly empty abstract terms about ‘human dignity’ you can be sure that they have no evidence or arguments to back up their position. It is difficult to understand why the act of sexual intercourse that leads to sexual procreation is any more ‘dignified’ or respectable than a reasoned decision by an adult to have a child, that is assisted by modern science. The thousands of children given life through IVF therapy do not suffer a lack of dignity as a consequence of their method of procreation. The Catholic church regards every embryo from the moment of existence as a living person. This position is not shared by most Western governments, and it would deny not only cloning, but IVF and all the medical knowledge and benefits that have accrued from embryo research.

There is much more danger of eugenics associated with developments in gene therapy and genetic testing and screening, rather than human cloning. The notion of clones of Hitler is frankly preposterous. Psychologists have shown that nurture is at least as important as genes in determining personality. It would be impossible to produce another Hitler, or Elvis, or whomever, by cloning or any other ART. Clones (people with identical genes) would by no means be identical in every respect. You only need to look at identical twins (who are genetic clones of each other) to see how wrong that assumption is, and how different the personalities, preferences, and skills of people with identical genes can be.The idea of breeding huge fighting forces is also confined to the realm of science fiction. The necessity of thousands of willing mothers, the nine month gestation process, and the many years rearing this child towards adulthood, means that cloning would hardly be an efficient technique for any mad dictator to raise an army. And there is no reason, in any case, to suppose that a clone would be any more willing or effective a soldier than any other human being – clones (like twins) are just as conscious and free as everyone else.

It should be emphasised that children produced by reproductive cloning will be ‘clones’ but not ‘copies’ of their parents. Different environmental factors, nurture, and the process of gestation mean that children will not be emotionally or mentally identical to the people from whom they are cloned. Furthermore, this objection would apply to all identical twins. A small proportion of identical twins do indeed suffer from psychological problems related to feelings of a lack of individuality. However, cloned children would in fact be in a better position than these monozygotic twins, as the clones will be many years younger than their genetic twins, which are of course their parents. They will not be daily compared to a physically identical individual, as there will be a gap between their ages, and hence psychological and physical characteristics, of tens of years.

Any reduction in the diversity of the human gene pool will be so limited as to be virtually non-existent. The expense and time necessary for successful human cloning should mean that it will only be used to the benefit of the small minority of people who require the technology. The pleasure of procreation through sexual intercourse does not suggest that whole populations will prefer to reproduce asexually through cloning. The only significant lack of diversity which can be expected will be in women who suffer from a severe mitochondrial disease. They will be able to use cloning by nuclear transfer in order to avoid passing on the disease which is carried in their egg cells to any offspring. This elimination of harmful genetic traits from the gene pool is no different from the eradication of infectious disease, such as small pox, and should be welcomed.

The desire to have one’s own child and to nurture it is wholly natural. The longing for a child genetically related to oneself existed long before biotechnology, but it is only recently that medicine has been able to satisfy it. In vitro fertilisation remains an imperfect technology. Couples typically submit to four cycles of costly treatment before producing a child. Evidently, the technique does not assist homosexual couples, couples where both partners lack gametes, or where the female partner suffers from a mitochondrial disease. Cloning would allow a child to be born to all these couples.

The decision making and the effort that will be required to clone a human suggests that the child will be highly valued by its parent or parents. Furthermore, we should not pretend that every child conceived by sexual procreation is born to wholly well-intentioned parents. The desire to have ‘a son and heir’ is common around the world but does not concern the welfare of the future child. Similarly, children are often conceived out of marital custom, in order to consolidate a relationship, or even in order to gain free accommodation from local housing authorities. Finally, many children are not intended at all, but are born as a result of unplanned pregnancies. There would be no fear of ‘accidental cloning’ that could bring a child to a parent who was unprepared, or unwilling, to love it.
