GM humans are possible, but do we really want them?
We are entering a new era as a species. For the first time, we are not only able to read our genetic code but also edit it. This will revolutionise our ability to treat disease and it will improve the lives of millions if not billions of people. But it means that, if we want to, we can now edit human embryos to “improve” the characteristics of our children. We will be able to create designer babies and these changes will be passed on to their descendants, which will change the human species forever.
