The ethical debate about what is now called “human gene editing” (HGE) began sixty years ago. At the time, eugenicist scientists wanted to use new knowledge about the structure of DNA to modify humans—to perfect the human species by making us more healthy, musical, intelligent, and generally virtuous. A consensus later formed that gene editing […]
The US government recently announced that it was lifting its moratorium on funding certain experiments that use human stem cells to create animals that are partly human. At present scientists are only interested in creating entities with some human qualities, but which remain “mostly” animals. For example, some scientists want to create a chimeric pig with a human-enough heart to transplant into a human. Distinguishing between humans and other animals is common in most cultures.
