What is germline manipulation?
Altering in fundamental ways the genetic code for a human being. Altering the code in ways that can be passed on from generation to generation, alterations that can create new subspecies of humans, alterations that change what it means to be human. That’s not science fiction. It’s well established technology in clinical gene therapy trials right now all around the country. It’s used in assisted reproduction technologies that allow individuals to test for genetic diseases before implanting an embryo, and changing those bad genes before implantation.
