Seconded. Not only does the law support this, but every argument I've ever come across has been about whether the cell-group(? I can't think of a neutral term that does sound dumb) should be considered a person once it has a full set of human DNA or if it isn't considered a person until it has a central nervous system. The last time I even heard of a serious abortion-rights argument hinging on Birth rather than Neural Development was decades before I was born. While the original post is interesting, I don't understand it's fixation on birth.
