The question is simple: from what or who the modern human came from?
We may never have a direct answer to this, (does not equate to godsdidit) because not everything that dies fossilizes, as that takes a very specific set of environmental conditions and circumstances. Closest we will get is through DNA analysis of what we do find, to see which things are closer or further apart in relation to other living and extant species.
Also see my ape/man graphic to get an idea of where we came from. Then study evolution in an honest fashion not colored by your Culture, to fully understand it.
