There are numerous textbooks on embryology which attest to that fact and I can provide quotes if you like. To say an embryo is a human being is not a statement of faith, it is a statement of fact, and if anyone wants to dispute I'll direct them to the aforementioned references and I would challenge them to state 1) if the embryo isn't a human being, what it is, and 2) the definition of human being.
As for law, I'm surprised by how many seem to lean on it with a degree a permanency and finality not usually attributed to it. Is it not plainly the case that laws can be both newly written, changed and/or removed? Law is simply an attempt to codify that which society believes to be true of good and which is based upon, or a reflection of, an underlying truth. By way of example, but without wanting to draw to direct a parallel, were not slaves, at one point, legally considered property, legally treated as less than human, and not deserving of human rights? Those laws pertained to the status of human being and were changed because of the recognition of an underlying truth. The law was made to fit reality; defined by it. Theoretically, could that not be the same here?
