First Monkey Clones Created by Technique That Made Dolly the Sheep

For the first time in history, scientists have cloned monkeys, using the same technique that made Dolly the sheep in 1996. The technique is called somatic cell nuclear transfer, in which an egg’s nucleus is removed and replaced by a nucleus from another cell, which is then developed into a embryo.

In a study published in the journal Cell, researchers say the cloning of animals by somatic cell nuclear transfer has been successful in 23 mammals, including mice and dogs, but up until now, cloning of non-human primates by somatic cell nuclear transfer has failed to produce offspring.

The creation of the monkeys brings up ethical questions, just like Dolly did in 1996, and more so now because humans are in the primate family.
