LOST WKND Issue N˚ 1
In April, the scientific community was jolted by news that Chinese researchers had successfully edited the DNA of a human embryo. It was a watershed moment: the first time humanity had edited its own germ line, the sex cells (eggs and sperm) used to pass on genes from generation to generation. Although the experiment—conducted by Junjiu Huang and his colleagues at Sun Yat-sen University—used non-viable embryos and produced unintended mutations, the implications are profound. Beyond fears over genetic engineering and “designer babies,” to manipulate the human germ line is to manipulate human heredity; evolution itself becomes malleable.
