For sure, if some research institution were motivated enough. I won't speculate if it's happened in secret, but cloning a sheep brings us pretty close to being capable of cloning a human. I would be more surprised if 30 years since the cloning of Dolly, we haven't advanced to the point where the only thing stopping us from cloning humans are ethical concerns.

I don't think cloning a human would be much harder than a sheep.

Yes, 100% the technology and skill is available today to clone a human.

The ethics are dubious and nobody with that technology and skill is going to attempt it. They're working on lab grown meat and replacement transplant organs.

100% it can be. Once it was done in animals there is nothing really keeping it done people and while im 100% on if it has been done secretly I would in no way be shocked to find out it had and think its more likely to have been than not.

I wouldn't be surprised if a human was cloned. The issue right now seems to be resolving the ethical issues over the technical ones.

We're either there or close, but just like last time you asked this, nobody's going to do this in secret. They'd be bragging their asses off.

I mean, I don't see why not, but having a clone isn't as big a deal as people think. Identical twins are already natural clones

Technically? I don't see why not

Currently, no.
They haven't even managed to clone any hominids from adult cells, yet. But they're not far off.

I think it's possible. If you can clone a sheep then why not a human?

I think this depends upon your definition of success. I think it could be done now such that you could get to a live birth, but not without serious health complications for the clone, probably resulting in an imprinting disorder or maybe something akin to progeria. You'd wind up with a sick infant instead of a healthy adult. Producing a copy of a human being as they are, if that is the definition of success, is still a ways away, probably a decade or more. This is without even considering the ethical issues with human cloning.

Yes, I believe some cloned humans already exist at secret military facilities. Area 51. Super Soldier clones.

No, and the ethics behind it are too screwed to try it.

Probably not cloning like scifi where exact body scars, broken bones, & memories transferred.

But china did try to hide some cloning human project researcher a while back. Not sure what happened there.
