I meant in a sense of mental development, like moral development for instance. It's nothing to do with when they are born, it is to do with how 'human' they are. The only thing that makes us special is our capacity of abstract thought, so when that child can do that I would say you cannot for certain destroy it. But that is actually quite late, and for a fair while the child could quite easily be that of an ape, for the amount of difference there is. They have said to look more ape-like than human, on occasion.
