I think that if one day this is applied to the human being, we would be crossing the barrier of morality, since the human being would no longer be a human being as such. It would be something like, human-animal hybrid. Suppose they carry out this experiment and it goes well, but other scientists come up with the idea of altering the genetics of the eyes and their shape so that they can see better, they also alter the shape of their ears and they modify their feet so that they can run better . The question we ask is: Who dictates how far the human body is experienced and modified?
