The first famous clone was the sheep Dolly. Since then, many mammals have been cloned; rats, cows, goats, pigs, rabbits, cats…
The method of cloning is rather a performance of “artificial twinning” which was applied on non-viable human embryos in 1993. They died at the latest six days later. “Actual” cloning would mean to take a cell from an adult individual, remove the nucleus and implant it in a fertilized egg that has had its nucleus removed. This has been done with frogs with a low success rate but certain scientists argue that they successfully cloned humans. There is no evidence for these claims (due to confidentiality) but at any rate, science is advancing quickly and if not yet, then human cloning might be possible in the near future. Although the majority of people agree that cloning is inhuman, the laws of cloning differentiate around the world.
The ethical issue
Cloning could bring about benefits in many medical areas such as cell development and various types of plastic and reconstructive surgery.
However, the whole way of cloning would be paved with unethical research.
There are many roadblocks for cloning but in a time of endless advances, no one really knows what might happen next (in terms of cloning). The fact remains though, that cloning is throughout unethical and should, at least in my opinion, never be practised on human beings.
yes… and wiki 😉
