Ética nos transplantes entre animal-ser humano discutida pela Academia Britânica

A manipulação genética, tendo em vista o benefício do ser humano, levanta várias questões éticas que ainda esperam resposta definitiva, embora seja amplamente reconhecido que esta assunto nunca será consensual.

When former President Bush mentioned human-animal hybrids during a State of the Union speech in 2006, most of the audience probably sat scratching their heads for a second. However, in the years since then, transplanting human genes into animals, whether to make better milk or study human diseases, has become a bigger and bigger issue.

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.
