If for some strange reason The bronze age never develops. The Stone Age Continues.
Old Stone age -New Stone age - 3rd Stone age
What kind of Political/Cultural - Europe and Mesopotamia - would whe be looking at.
Stone age can have Empires, [ie Incas, 1st dynasty Egypt, etc.]. Major Agriculture, Major trade, [Beaker? peoples]
?But would whe still have those Villages on Stilts, in the middle of lakes? or would some Mediterranean Empire have conquered Europe [aka Rome] and imported Cities.?

?Any Ideas or Thoughts?
