This story highlights what I think is one of the more common misconceptions about cloning.

It sounds like the woman in this article feels like she's getting her old dog Booger back. While it's true she's getting an exact genetic replica of Booger, he could end up being very different than the original.

Much of Boogers personality and capabilities were the result not only of his genetic make-up, but of his life experience. There's no way to exactly duplicate that experience, so it's very likely the cloned Boogers will be somewhat if not very different than the original. This could be true for some of his physical characteristics as well, as some of them are influenced by life's experiences.

While I believe cloning can hold great promise, people need to realize it can't be used to bring a dead loved one back to life.
