Cloning was presented by Ian Wilmut for cloning animals, specifically the sheep. He saw that it could be useful if he could clone humans. For example, say that someone has a disease right? And it's like impossible to find a perfect make for the victim. All the creator has to do is make a clone of the organ and input the correct things to connect the cloned heart into the body system. And we dont need to use donors, or people who donate their body parts for people who need body parts.
