Hybrid embryos and ethical confusion
The Human Fertility and Embryology Act from 1990 is being overhauled and the current white paper proposes to ban the use of hybrid-embryos conforming to public concern.
Opponents are concerned about the ethical and moral issues involved though thre is already a move to collect the skeptical comments from some scientists. Already the camp opposed to the process are using the american technique of raising the certainty threshold before a scientific proposal can be researched. It's been well-tested in the US: someone challenges the proposer to acknowledge that there is some doubt about the outcome of the research and on that basis, argues that the proposal won't deliver and is therefore not worth doing. This approach has been used to prevent climate research, to oppose pesticide limitation, limit stem cell research, and as part of widespread opposition to environmental controls. Now the approach is being used in the UK to limit stem-cell research.
Any scientist worth the name will argue that there is always doubt - that's why we do experiments and study real-world data. In the case of the hybrid embryos, there's no guarantee that they will deliver everything we need in terms of stem cell research but that's not a reason for rejecting the proposed work.
The stronger case is made by those who have moral or ethical objections but these are quite vague. A common objection is that it is playing God, creating a "something", a potential new species which has not naturally arisen. This is tantamount to saying that if variation arises naturally then it's OK to exploit it, but not using techniques to induce those variations. This objection unravels when we look at animal husbandry, and especially so in the deliberate manipulation of plant species. Agriculture has been doing this kind of artificial manipulation of nature for centuries. The only difference is the timescales.
When we think of playing God, we are of course invoking the presumed capabilities of a mythical all-powerful being, the perjorative intent of the phrase being used to make us think that the process is inherently wrong, not because the outcomes may be harmful but the very act of manipulating nature is wrong in itself. This seemingly goes not apply to the use of electricity, or even fire, processes which directly and deliberately manipulate nature. It also divorces the consequence from the cause, which is actually the whole point of ethical argument. Is it wrong to produce antibiotics for example? For years we have been using bacteria to produce quantities of antibiotics:
Research is very well established in this area.
But to be fairer, the concern is often really about the "human" part of the process, the human DNA. Here the moral issue really comes down to the religious basis for the objections. It;s about interfering with human biology at a low level. Medical intervention is apparently acceptable but low level cellular intervention is a problem. But what exactly is human? Is it the DNA, which can be constructed from inert constituents and assembled - it hasn't been done yet but the technology is available? And what of the living host cell that would have such DNA introduced to it? If we judge it to be human, what then of the so-called soul? At what point does conception take place? Would such a hybrid be 1% host soul? Soulless? Incomplete soul? The raise absurdly doctrinal questions for religious people reminiscent of the Inquisition.
One argument though is based on statistics. The claim is that such embryos would be 99% human. But in fact we share 85% of our DNA with mice. Does that make us 85% mice or mice 85% human? And in fact at the level of genes, we share 99%.
So some of the confusion is around what constitutes a human. As the mysteries of life are unravelled, there will soon be nothing supernatural about creating living tissue and the ethical issues will properly concern our understanding of what constitutes a person. Collections of cells grown in a culture do not constitute a person and the ethical question is really about whether it is moral not to study such tissues.
As Dr Stephen Minger of King's College, London, put it:
At present we have no therapies to even alleviate the symptoms for conditions such as Alzheimer's, spinal muscular dystrophy and motor neuron disease, never mind make an impact on disease progression.
So the ethical dilemma is in practice about stopping research because of quasi-religious notions of what being human consists of. The consequence of preventing this research is the rather uncharitable condemnation of sufferers from incurable diseases to continued suffering.
The possibilities for medical research now becoming available are precisely brought about because we are understanding that the biochemistry and genetics of living organisms has an enormous amount in common. Human life is not special and that is the broadside to religious thinking for it undermines the notions of chosen peoples, creation myths, notions of souls, sins, redemption and some all-powerful being that supposedly created us.
Because science is demonstrating life to be prosaic, commonplace, generic, mundane, and above all intelligible, religious and mythical interests are coming to the fore. Building on popular prejudice, they seek to role back scientific research but it's the people who suffer incurable diseases who will pay the price.
