Practical Ethics

Re-creating mammoths and the family dog: two different cases

The idea of reproductive cloning can easily be perceived as offensive, as a practice that constitutes the dark side of cloning and should be prohibited under all circumstances, by contrast with therapeutic cloning, the benefits of which are increasingly acknowledged. However, such reactions typically assume that it is human cloning we are talking about. Regardless of how we should assess this latter practice, it seems difficult to make a plausible case for a complete ban on reproductive cloning of nonhuman animals. On the contrary, such a technique appears to open up exciting prospects. A group of Japanese scientists, as recently reported in the press (by the BBC and the Guardian, among other sources) have thus managed to produce clones from dead mice that had been frozen for 16 years. According to the aforesaid scientists, this achievement raises the possibility of re-creating extinct species such as mammoths from their frozen remains – a bit like what happens in Steven Spielberg’s movie Jurassic Park.

Reproductive science: is there something we're missing?

Thirty years after the first test-tube baby, Nature asks various experts for their views on what the next thirty years of reproductive medicine will bring. Some of the more startling predictions are:

• No more infertility, with both children and 100-year-olds able to have children
• Embryos created from stem cells, increasing the ease of embryo research and genetic engineering of children
• … with the resulting greater availability of embryos making it easier to create cloned humans
• Artificial wombs, enabling babies to develop outside the mother’s body
• … which, some worry, could become compulsory as an alternative to abortion, or to avoid premature birth or fetal alcohol syndrome
• ‘Genetic cassettes’ implanted in embryos to counteract the effects of inherited diseases
• Increase in litigation following evidence that IVF babies may later suffer adverse effects from the environment in which they were grown as embryos

Cloning and animal exploitation

The Daily Mail reports this morning that 8 clone-offspring cows have been born in the UK. Also today, the first survey of public opinion on ‘clone farming’ has been released indicating significant unease and opposition to the idea of meat products or milk from cloned sources.

There are strict prohibitions on reproductive cloning for humans in most countries (for example, the recently debated HFEA bill in the UK, and the Human reproductive Cloning Act 2001). However there are few, if any, constraints on the cloning of animals. Is this the start of a new era of animal exploitation?
