|Too many times, scientists do things just because they CAN.
I'm sorry if this offends or upsets anyone, but as a research scientist I felt I had to respond. An ethical scientist does not do something just because they can, but because they are trying to study an experimental question. Unfortunately, in our world where the media only gives us 30 second sound bites, this is often lost.
Cloning is used to study a number of very important questions. For instance, in a grown human are there cells which are capable of regenerating nerves or entire organs? This is important in searching for a cure of such things as paralysis due to injury, Parkinson's disease and for people who need transplants. Also, the studies in cloning have allowed a better understanding of development before and after birth. Finally, it has shown us that cloning of any organism (whether it's a pet or a family member) will NOT produce the same organism.
I think the story of cc is very instructive, but should not be seen as a modern example of Frankenstein's monster.
