[You said yourself that the alternative explanation is a priori false.]

Yes, it is... *now*.

That's a total contradiction. If it wasn't false at the beginning, then it wasn't false a priori.

So, how many other theories do you think don't need to be reevaluated once they're formulated?

And the scientific understanding of the origin of species was not until Darwin.

Non sequitur. And an especially silly one considering we're talkign about evolution, perhaps the most constantly re-evaluated theory in history.
