On July 5, 1996, after 276 failed attempts, a team of scientists at the Roslin Institute at the University of Edinburgh achieved something remarkable:ย Theyย managed to clone a sheep.
After seeing her, the media went wild, quickly incitingย hysteria about what would come next. If scientists knew how to clone a sheep, how soon would it be before they started cloning humans?

Over the last two decades, a number of different animals have been cloned in the same wayโcows, horses, cats, dogs, pigs…. Despite the success in cloning various mammals through nuclear transfer, cloning is still very difficult to pull off. The process is prone to introducing genetic errors, which results in many cloned offspring dying young.

These days, Alta Charo, a professor of law and bioethics at the University of Wisconsin, said no one is really researching reproductive cloning for humans. It’s simply too inefficient and error prone to make it worthwhile.ย Some researchers have suggested cloning technology could be used to rebirth lost children or prevent disease, but Charo said no one has filed an application with the Food and Drug Administration to get started onย this kind of research.
