Like Dolly the Sheep was before them, two healthy baby macaques were recently cloned after decades of research. Though more than 20 species have been cloned successfully, the macaques are the first primates. After 20 years of trying from the most talented groups, and nothing working, finally this works. This research is going to help cloning of all species. Researchers expect the cloning to help in the understanding and treatment of disease, and especially genetically-linked disease.
