Behind the Chinese trial also lies some bold thinking about how evolution can be shaped by science. While the natural mutation that disables CCR5 is relatively common in parts of Northern Europe, it is not found in China. The distribution of the genetic trait around the world—in some populations but not in others—highlights how genetic engineering might be used to pick the most useful inventions discovered by evolution over the eons in different locations and bring them together in tomorrow’s children."
