Two cloned monkeys make us wonder: When will humans be cloned?

Zhong Zhong and Hua Hua are two monkey clones in China. It’s the first time researchers have cloned a primate, and it could lead to major medical advances.

Zhong Zhong and Hua Hua, two identical long-tailed macaques, seen here January 20, 2018, were born eight and six weeks ago, making them the first primates -- the order of mammals that includes monkeys, apes and humans -- to be cloned from a non-embryonic cell.
