Two monkeys have followed in the footsteps of Dolly the Sheep by becoming the world’s first primates to be cloned from transferred DNA.
Identical long-tailed macaques Zhong Zhong and Hua Hua were born eight and six weeks ago respectively at a laboratory in China.
The success marks a watershed in cloning research and raises major ethical questions.
The scientists hope to pave the way for populations of genetically uniform monkeys that can be customised for ground-breaking research into human diseases.
But the cloning of monkeys will be seen by some as a step toward the creation of human clones.
