Didn't you see the story about the wolf lady on yahoo news the other day? She was abandoned by her parents in Russia and, no joke, was found when she was 15 running around on all fours growling and barking like a dog. She now leads a somewhat normal life but, no embryo could do that.
Technically speaking, a baby CAN survive on its own, it will just starve, freeze, etc without assistance, but the fact is it CAN survive outside the womb, a fetus cannot.
As far as your last statement, instinct! Are you saying that your cognitive ability and intelligence is the same as a baby?? Of course not, because you ARE the sum of your experiences. I'm sure no baby has injected a gram of test into it's ass either!
