# First Cloned Mammal: Dolly the Sheep

> Scottish scientists cloned a sheep from adult DNA, breaching the apparent barrier to reproductive cloning and sparking urgent bioethical debates that persist today.

## Summary

Zhong Zhong and Hua Hua are a pair of identical crab-eating macaques that were created through somatic cell nuclear transfer (SCNT), the same cloning technique that produced Dolly the sheep in 1996. They are the first cloned primates produced by this technique. Unlike previous attempts to clone monkeys, the donated nuclei came from fetal cells, not embryonic cells. The primates were born from two independent surrogate pregnancies at the Institute of Neuroscience of the Chinese Academy of Sciences in Shanghai.
