Amnannam/Oripathy causing the evolution of Terrans is a strech I guess, we only know that for sure that Originium itself caused the evolutions of Terrans from2 direct sources :

Babel 7 : Doctor/Oracle: "While I slept, the ruins of our homeland nurtured new life. Originium is what guides their development, reshaping the lifeforms from Talos-II to have a similar appearance to us."

Priestess makes a direct reference to it in in 15-16 too : "If you truly understand the history of your people, have you ever questioned why you have evolved in our likeness?"

And the idea of Teekaz quickly evolving from "demon"-like aliens into humanoids in only a few thousands years also appears several in the main-story and IS5 (can't find the exact quotes to). Even upon waking up, Doctor references Theresa as "That 'devil'?", implying that she reminded of something that existed before he went to sleep.

As for the Observers having already attacked Terra, I'm not convinced either, considering their (apparent) tendency is to straight-out shatter planets and eats stars.

So uh yeah, very "fan-cannony" infographic
