You are thoroughly missing the point I'm making about the professor's argument.

And you call *me* a moron?

Consider your first sentence, about parasites.
Since the female has organs pre-existing which activate only during pregnancy, to feed the baby *after* birth; and pregnancy only results, based on a combination of the woman’s physiological state and her actions (which are not incidental, like walking through tall brush to acquire deer ticks), that pretty much destroys any idea of the fetus as parasite.
