Strong agreement here.

Sometimes, as your paper is saying is the case, they're orthogonal to them.

From your article, emphasis mine:

"While this article’s findings suggest a fetus is biologically classified as a human at fertilization"

The problem you have is that this paper doesn't discuss children at all, merely that a fetus is of the human species. It's basically tautological so of course it's essentially unanimous. A human fetus is a human fetus and not, say, a chicken fetus.
