Abstract

Might the 2018 birth of two designer babies in China write the opening paragraph for the next chapter in the history of eugenics? The worldwide scientific community has tacitly put a moratorium on human clinical application of CRISPR gene editing, waiting until unknown risks can become known. But this ethical agreement has been breached, and calls are now being heard for more rigorous regulations. Perhaps religious and spiritual leaders can join the bioethical chant: the yellow light of caution is flashing.
