"Modern science has made claims of no use, or de-selected use and then was PROVEN COMPLETELY WRONG, as more knowledge was discovered."

This is incorrect. The point is that these structures are not being used for their original function. For instance, the ostrich limbs are no longer used for flying, even though they are obviously underdeveloped wings. The appendix no longer is used to digest cellulose, which is the function it had originally in our ancestors. THAT is what a vestigial organ is, and that was the understanding of what one is at least since Darwin.

According to who? The same people who were so brilliant as to be completely wrong about their non-use in the first place?

the ostrich limbs are no longer used for flying

Maybe they are used for balance while running? Who knows?

The appendix no longer is used to digest cellulose, which is the function it had originally in our ancestors.

And how do we know that? Let me guess, they make this absolute authoritative statement by looking at a fragment of monkeyman's kneecap.
