Can you clone a human?

Answer

Theoretically, this is no problem at all. There is a whole laundry list of cloned animals available these days and some animals clone themselves in nature!

But first, let’s take a look at the experimental reality.

Dolly, the first creature we know of to be cloned and to become world famous even as keychains, was a sheep. In the media “first cloned sheep”. What they didn’t mention was that about 250 attempts (read: pregnancies, read: ovulations) were preceded to bring a “healthy” sheep into the world that was cloned. Since then, sheep, monkeys, mice, mules, camels, and so on have been cloned. Then you don’t have to think far and you arrive at the human being.

Extrapolate Dolly’s data to homo sapiens and you can theoretically say that this can be done. There is, of course, an ethical issue that is beyond the scope of this question. There have been reports of human cloning around the turn of the century, but these have never been scientifically confirmed.

Do clones exist? Yes. Any monozygotic twin can view their twin sibling as an “identical” natural clone of themselves. However, developmental differences can arise due to environmental factors (nutrition, etc).
