The Reapers? All three of them??? Are the Asari to be counted in the same genus as Homo sapiens? On the other hand, it would Hand Wave the whole Rubber-Forehead Aliens trope in a rather elegant way, so the verdict is still out as to whether or not its a case of Fridge Logic, or Fridge Brilliance.
It is mentioned in the Forerunner Saga that the Prehistoric Human Civilization after the Human- Forerunner War was split into multiple sub-species, collectively known as 'The People'. Over time, most of these subspecies would die out, leaving only Homo Sapien Sapiens as the single remaining variant. Perhaps the Asari are/ evolved from one of these sub-species? The existence of Prothean Ruins on Mars and the fact that the Protheans meddled in Asari development are both known facts, so this could be explained quite nicely as Protheans finding a population on earth that matched their specifications, taking them away and tweaking them, and then them being left on Thessia...
