Now, a year after English scientists implanted human stem cells into bovine egg cells, Britain's Academy of Medical Sciences has launched a study to determine the ethics of creating human/animal hybrids.
The study hopes to mark out the boundary past which genetic mixing becomes unethical. Over the next year, the study will investigate what percentage of DNA constitutes a human, as well as looking at other issues like the creation of human stem cells from animal eggs and the implantation of human cells into animal bodies.
While most people support implanting a single gene for a human disease into a primate for the sake of research, the level of unease rises as the genome becomes more and more mixed. Certainly, with the technology available to create a 50/50 split hybrid, this field calls into question how we define ourselves in particular, and species at large.
No doubt the scientists conducting this study are serious, qualified, and respectful of human life. But if any of the scientists show up with a little red dude dressed like them, I'm gonna start worrying.
