PARIS: Scientists in China on Tuesday (Jan 16) announced that they have cloned the first healthy rhesus monkey, a two-year-old named Retro, by tweaking the process that created Dolly the sheep.
Primates have proved particularly difficult to clone, and the scientists overcame years of failure by replacing the cloned cells that would become the placenta with those from a normal embryo.
