In the UK a scientist is making a case to edit the DNA of human embryos. Dr Kathy Niakan claims that these experiments would "provide a deeper understanding of the earliest moments of human life and could reduce miscarriages." This is possible by using the Crispr process that, in short, “turns off and replaces specific genes.” This is an exciting scientific possibility, but is far from without criticism. Many people think that editing the genes of an embryo is “playing god” and should not be tested.
Personally, I have nothing in my morale standard to claim this wrong or evil and see no reason for this not to happen. We are likely to understand a dark corner of science, miscarriages, and by getting more experience with gene editing the possibilities of that alone is worth more than any moral standard she may break.
