Would it be ethical for scientists to try to create babies that have genetic material from three different people? An influential panel of experts has concluded the answer could be yes. The 12-member panel, assembled by the National Academies of Sciences, Engineering and Medicine, released a 164-page report Wednesday outlining a plan for how scientists could ethically pursue the controversial research.

“The committee concludes that it is ethically permissible” to conduct such experiments, the report says, but then goes on to detail a long list of conditions that would have to be met first. For example, scientists would have to perform extensive preliminary research in the laboratory and with animals to try make sure it is safe. And then researchers should initially try to make only male babies, because they would be incapable of passing their unusual amalgamation of DNA on to future generations. FULL REPORT
