How about a human body with a beating heart?....And a beating heart that continues to beat even after being removed from the womb?
Is that enough science for you?....
Negatory good buddy. No higher thinking, no reactive movements, no sentience, just another parasite living off something else's otherwise healthy body. All you're left with is some day this could be a person. It doesn't mean it will be a person(anything could happen before birth), especially doesn't mean it'll be a good person(given that the mother either doesn't want the child for whatever reason).
But since we're down the science road, take it a step further. An overly cold and scientific person's interpretations;
We're already living on an overpopulated rock as it is. Why are we even discussing this?
Every month a mother has a menstrual cycle. Those are also cells that could be human. Does that mean from the age of 11 on women should be having unprotected sex to save more human life?
