Guys, I think we're all failing to consider a potential validation for this theory. That is the fact that Ace is so evolved that he devolved, and became capable of asexual reproduction. However, Ace only got half way there and thus, he did not produce an exact copy of himself, but rather only a female version. Then, he named female-Ace Anne because he was actually capable of conscious thought when he was just born on account of learning to speak, read and write while in the womb. Cause he's so evolved. Or devolved. I forget. COME AT ME!
Also, I personally think Anne is Naruto's dad.
