Guys.....isn't this going a bit too far?

Indeed as I said those aren't formations those are modification to what already there

You may be surprised to know that pretty much everything is "already there" by the first trimester. It's just a matter of all those things continuing to grow and mature. Which they keep doing for years.

But not everything

Second It's still formation in the first and modification in puberty

But even if we grant your promise those things are still bodily reliant on the mother to survive thus rendering the argument is secondary really
