This is really just carrying on from the genetic engineering thread in biology....

I was just wondering how far do you think a human has to change before they become non-human?
Is it simply by removing an emotion that a person becomes non-human, or do you think the whole behaviour of a person needs to change before they become something different. Perhaps if we keep the human brain but changed the body maybe into some sort of android, would you still think of that person as a human ?
