Aaron Levine, a bioethicist at Georgia Tech, said cloning's biggest impact on human health is likely to come from animals raised to produce organs, tissue or biological drugs that will not be rejected by the human immune system.

“I think human cloning will disappear,” he said.

“I think there's just not ultimately enough demand, not enough that you can do through cloning that you can't do through other things.”
