It really doesn't. It just states that the song the Red Lyrium has and the song the Old gods have are similar. Coincidence making Dragon Age, and all, your words. Their purposes are diametrically opposed.
The whispering isn't just similar. It's exactly the same. I have no clue though if the whispering is the song they hear, but I would hope that the song is something ethereal and not just "GAbhojaohofhaohaohf"
I never stated Corypheus could hear the calling. I stated that he and awakened Darkspawn have to have some level of communication with Old Gods for Dragon Age Awakening, as well as the revelation that the Architect created the fifth blight, to be plausible, as other options are completely comical. I never stated they need the Calling to control Darkspawn, only that their control cannot be stronger than the calling, or Dragon Age Awakening, already considered canon, could not have occured.
Except Awakened Darkspawn no longer have a connection to the Old Gods. That's precisely what the Architect's research was about. Sundering the connection and allowing the Darkspawn to live their own lives. For all we know, the Architect either: A) dug in various areas and not just one,

used the Darkspawn under his control to find the area to dig, or C) remembers some things from when he was a Magister and quite possibly one of those things is the location of the Old Gods and where they're buried (if the Magisters ever knew, though it might be unlikely).
What shipments? We know the Dwarves did not have knowledge of every corner of the Deep Roads by virtue of the Ancient Thaig, and the fact that it's not in the Shaperate's memories. It was only necessary to dump one undetected Broodmother into the Deep Roads to cause, well, everything that occured. Do you know how many undetected fauna and flora go around this planet and flourish, without natural predators that you think that they would leave a paper trail for some reason? Perhaps it's just me, but I've always seen the Darkspawn/Old God correlation to be directly linked to that of the Golden/Black City and the Magisters, as soon as you get close to it, you corrupt it. As such, I don't see where you are getting shipments from, why the Tevinters would note it on ledgers, or where you see the Tevinters, who could not care less about anyone, would care about leaving an experiment to Dwarves they hold no allegiance to. Like I 've stated, if the Imperium did not create Darkspawn, it would not only be part of their history but part of the surrounding neighbors of Tevinter via travel, it would get out unless the Imperium deems it neccessary to hide, and they have no good reason to.
Have you seen a broodmother? They're fused into the wall/ground. I'm getting shipments because you're saying that the Imperium just decided to drop Darkspawn/Ghoulified women (broodmothers) in the Deep Roads. For one thing, the Primeval Thaig couldn't be a dropping point because it's untouched by Darkspawn, and we have no clue if there are others (though I believe there are)
I never stated the Darkspawn were a scientific creation. Only the Kossith seemingly study science. I feel they are a magical creation, though, and given the unfettered control the Tevinters had over Thedas, what would stop them from taking magic to those levels, as they were already approaching being like Darkspawn come the First Blight anyway.
Scientific or magical, the taint cannot be recreated artificially. It can be studied like Avernus did, but it cannot be recreated artificially.
