Lightbulbs are unnecessary, you can get light from candles and gas mantles. And, of course, mobile phone ringtones are unnecessary (no, they REALLY are)... You see, some new developments look lilke they might be good, but they aren't, others look good and really turn out to be.
Cloning technology for the preservation of advantageous traits in many species is well established; every time you take a cutting, you're cloning. It's feasible that such technology could be very useful for increasing yields from ethically reared animals, for eliminating genetic disorders that make some breeds of animals (even older breeds) less viable or healthy, reducing costs of said practices thus lowering price or increasing profits, etc. I have no ethical problems with any of that. And providing the practice is done in such a way that I can view and evaluate the science and practices for myself, I'll make my mind up application by application, which is the rational thing to do. |

No, you take a tissue sample and add in a set of chromosomes from an adult into a new embryonic cell, culture that for a while and add it to a parent.
Rather like taking a tissue sample from a plant, dropping the end in hormone rooting powder with fungicide, rotting that in pompost (a massively un-natural medium for growing plants) or water (even odder), and potting up before planting out. That ain't natural, you know.

The practice is surely a good deal more complex than that and presumably involves a lot of trial and error on our part. At what point will we know we have got it spot on? |
Well, it is and it isn't more complex. In essence, in terms of what's happening, it's simpler. In terms of actually doing it it's way more complex.
When will we know if we've got it spot on? Why do we have to have it spot on, and what do you mean by 'spot on' anyway? I'm not sure I agree that such a question is meaningful. Are you referring to animal welfare, safety, edibility, or what? |
