[mass effect] If Andromeda isn't "reaped" why are the races in Andromeda only as advanced as the races from the milky way?

If andromeda was left alone by the Reaper species or ignored entirely, and intelligent life evolved reliably every million years, Wouldn't the races in Andromeda be a lot more advanced?

It can't be just luck that even without help, the old races just wipe themselves out?

In the Milky Way technology was much more advanced because it was heavily seeded by the Reapers with advanced tech. 

That said, the Jardan were moderately advanced, a bit below the level of the Protheans, but they recently had a galaxy wide catastrophe and screwed up the galaxy, so less advanced technology.

Even without help, yes, the old races do wipe themselves out. It's a major plot point.
