[Dead Space] Origin of the Necropmorhs?

What is the origin of the Necromorps and the Markers? Are they a bioweapon developed by an unknown alien species that they lost control of when they deployed it or had an accident with it or are they just a fluke product of evolution?

Prevailing theory is that they're a race that has ascended to evolutionary perfection. Functionally immortal and able to exist for billions of years. They're the true end of existence a perfect harmony between life and death. Reproducing by seeding worlds with their markers and waiting millions of years to gestate into a new moon. 

Another theory is that they're the natural universe and we're the aberration. That death and lifeless rocks are the natural order and worlds like tau volantis and earth are freak mutations the brethren moons correct.
